Green Pond, Bournes Pond, and Eel Pond in East Falmouth

A week after a day-long symposium on the potential for outfall pipes to handle the Cape’s wastewater problem, I’ve finally figured out what’s been bothering me.

It seems that wastewater managers and engineers, in their infinite wisdom, operate according to the “if it can be complicated, why make it simple?” ethic.

The speakers at the ocean outfall forum did not mince words: it would take no less than an amendment to three state acts protecting marine resources—not to mention, years of study and millions of dollars— for an outfall pipe to be constructed on these shores.

They were less candid about the probable impacts on the environment— and were subtle about the whole reason for entertaining the idea of an ocean outfall: it’s cheaper than the only other “approved” method of disposing of wastewater.

Having attended my fair share of conferences, symposia, summits, and forums on wastewater, it seems that there are two distinct schools of thought on the issue. Some play by the rules, insisting there is no way to serve an entire municipality with anything other than sewers and wastewater treatment plants. Others push for “alternatives” such as composting toilets and shellfish aquaculture— options that seem outside the box until you realize that’s the way humans have been disposing of their “waste” for millenia.

An important difference between these two schools of thought is the attention and resources given to the “big pipe” option, while grassroots groups are left to their own devices to promote eco-toilets or aquaculture. Kudos to the Falmouth wastewater committee (CWMP-RC for short!) for opening their minds and supporting a successful town meeting article to give sewering alternatives adequate study— while the taxpayer-funded report by the engineering firm Stearns & Wheler did not.

Known unknowns

Popular in places where sanitation services are lacking, outfall pipes have fallen out of favor around the globe. Speaking on “possible environmental impacts,” Batelle scientist Carlton Hunt pointed out that the effects of putting semi-treated wastewater into our precious ocean are pretty much unknown.

Think about what products you use in the shower, the kitchen, the laundry room. Would you want to swim in it or eat it later on the half shell? What about road runoff that flows into storm drains?

Dr. Hunt also pointed out the anti-microbial nanotechnology that is appearing in everything from hand sanitizers to socks. David Dow, of the Cape & Islands Sierra Club chapter, pointed out that the byproducts of pharmaceuticals and personal care products are known to cause reproductive problems in fresh-water fish and amphibians. Studies have shown these contaminants of emerging concern in most of the country’s drinking water supply. What will they do in the ocean? We simply don’t know.

We also don’t really know what pumping precious drinking water into our toilets and sinks, and back across town for treatment will do to the water table— or to our municipal energy bills. We may not be water-poor on Cape Cod, but as the Dr. Hunt pointed out, we don’t know what to expect with climate change. Is it wise to build energy-intensive infrastructure in this age of sea level rise and uncertain weather patterns? How many more wind turbines will we need to handle the additional energy demand? (and how will nearby residents feel about that?!)

A truly holistic approach

Nate Weeks of Stearns & Wheler-GHD, with Dale Saad of the Barnstable DPW and Paul Niedzwiecki of the Cape Cod Commission.

There are essentially two reasons for considering an ocean outfall: the wastewater need not be treated to a point where it’s basically drinkable (through reverse osmosis)and town-owned land resources for groundwater discharge are dwindling.  Finding a suitable discharge site is complicated by the need to avoid putting nutrients back into the ground, which would require sewering the discharge area.

All these problems add up to one thing: groundwater discharge will be expensive.

One of the main messages from the panelists is that we need a “holistic approach” to solving our wastewater problem.

For hydrologists, that means recharging the treated wastewater into the groundwater or for irrigation. For Paul Niedzwiecki, director of the Cape Cod Commission, “holistic” means we need to collaborate as a region, rather than as individual towns. For Nate Weeks, of Stearns & Wheler-GHD, the term means we need to consider all the big-pipe options, no matter the regulatory obstacle course. For residents advocating for eco-toilets, aquaculture, and inlet widening, the answer lies in using our unused nutrients as compost and fish food, removing the “waste” from the wastewater equation.

It could be that being truly holistic means trying all these approaches, but in the end, decisions will have to be made. Why not make it simple, if we can avoid the complications?

Nicole Goldman, owner of “g”Green Design Center in Mashpee Commons, said that people walking through her door are not always aware of the simple steps they can take to become more green.

With her “one-hour speed greening” service, she walks customers through their homes, recommending a switch to plant-based cleaning products, setting up an easy recycling and composting system, and other low-impact ways of greening the household.

Step 1: Reduce Your Consumption

Now in business for four years, Ms. Goldman said she has seen a growing demand for eco-friendly products and services, and the market— and the tax code— are responding.

“People are not sure where to begin. They get overwhelmed and think they have to do everything at once. We help give them a jumpstart,” Ms. Goldman said.

She added that even though some of the products in her store are more expensive than what one might find at Home Depot, the quality and durability makes them a more ecologically responsible choice— and will end up saving customers money.

“Being green is about thinking smartly about the materials you put in your house, what you ingest, and what resources you consume,” she said.

Step 2: Energy Efficiency

Homeowners interested in reducing their energy bills should take advantage of a home energy audit before replacing windows or insulation, she said. She recommended a comprehensive home energy audit provided by Cape Light Compact for a small fee.

“People are a lot more educated and aware about their energy use. They see the costs of fuel going up. It’s not just about saving money, but it’s certainly a forceful incentive,” Ms. Goldman said.

According to Cape & Islands Self Reliance, federal tax credits for household renewable energy have been extended for another year, meaning homeowners and businesses can qualify for rebates of up to 30 percent of the cost of installing wind turbines or solar photovoltaic systems, solar thermal systems for heating and domestic hot water. These systems generate renewable energy on-site and sell any unused electricity back to the grid.

“The paybacks are much quicker now. Not only does the government pay back the cost of the system, you then go on to enjoy free use,” Ms. Goldman said.

Step 3: Compost is Black Gold

If installing solar panels or a wind turbine is not an option, there are still a number of ways to establish eco-friendly habits in the home.

Anne-Marie Runfola, a composting expert and member of the Falmouth Farmers Market board of directors, said that the average household can reduce 30 to 70 percent of its trash by composting food scraps and recycling.

“We don’t have the space for landfills, so we’re trucking and training trash farther. That’s bad for air quality, carbon emissions, and the economy,” she said.

Composting has the added benefit of being an excellent fertilizer for a garden or potted plants. By mixing a carbon source such as leaves with nitrogen-heavy compost, nutrients are “fixed” at the source, helping control nitrogen runoff and erosion, she said.

Using compost instead of fertilizer made from petrochemicals on one’s garden has much less of an impact on the environment— and on the pocketbook, Ms. Runfola said. “By throwing food out, we’re paying for garbage to be taken away, and we’re paying again for fertilizer to go in,” she said.

Step 4: Eat your vegetables

While carbon dioxide has grabbed most of the attention as a greenhouse gas, nitrous oxide and methane are even longer-lasting and effective agents of climate change.

For that reason, the European Nitrogen Assessment reported at conference held this month in Scotland that the best thing people can do to reduce their nitrogen footprint is eat less meat, said Eric A. Davidson, a senior scientist at the Woods Hole Research Center.

Livestock are not particularly efficient at converting protein in the food they eat. A cow converts 10 percent of the protein it eats into meat products that humans consume. Pork and chicken are a little better, and fish is probably the best. So eating meat is wasteful in terms of the protein needed in the human diet.

-Eric Davidson, WHRC

That protein inefficiency has upstream effects, Dr. Davidson said. The greenhouse gases created by confined animal feeding operations and the fertilizers required to grow crops to feed them amounted to 6.3 percent of total US emissions in 2009, according to the US Environmental Protection Agency.

Fertilizer and manure runoff to the Mississippi River has created a “dead zone” in the Gulf of Mexico due to an overabundance of nitrogen, killing fish and other marine life.

Dedicated carnivores need not give up meat entirely, said Dr. Davidson. As demonstrated at the nitrogen assessment conference, simply reducing the amount of meat consumed each day or at each meal makes a difference, while satisfying hunger.

“It’s probably not a big enough difference for mitigating our local problem of nitrogen in our sewage. But for the Mississippi River or global climate change, one thing everyone can do is reduce the portion size and frequency of eating meat,” Dr. Davidson said.

What’s your nitrogen footprint? Calculate it here!

Step 5: Drive less, ride more

With gas prices topping $3.83 per gallon in Falmouth yesterday, people are motivated to find alternatives to driving, said Thomas S. Cahir, executive director of the Cape Cod Regional Transit Authority.

Since last July, the bus company has seen 16 percent more riders on its fixed route service over the previous year. Ridership on the SeaLine from Woods Hole to Hyannis was up by nearly 16.5 percent, while the WHOOSH trolley from Woods Hole to the Falmouth Mall was up by 15 percent.

“We’ve always felt the geography and seasonal aspects of the Cape really scream out for a vibrant and robust transport system. But it’s hard to get people out of their cars,” said Mr. Cahir, pointing to the CCRTA’s new hourly schedule and billing system on its B-bus service as reasons for increased ridership.

According to the American Public Transportation Association, cars and trucks are responsible for 33 percent of total greenhouse gas emissions in the United States, but a person who commutes 20 miles a day by bus instead of driving can reduce their carbon footprint by 10 percent.

Mr. Cahir said the CCRTA’s bus fleet uses 20 percent biodiesel, increasing the environmental benefits. The CCRTA plans to expand with a route in Bourne and Sandwich by October and a statewide public transportation pass that can be used from Logan Airport to the Steamship Authority and island bus systems by next year.

Step 6: Bike to work

But the most ecologically responsible way to get around is bicycling, said Edward S. Gross, chairman of the Falmouth Bikeways Committee.

“Biking is a non-polluting activity and contributes to our own health. It’s also a community service, reducing congestion on the road,” he said.

Since the Shining Sea Bikeway was extended in 2009, use of the nearly 11-mile path has increased by 50 percent, averaging 1,440 users on a weekend springtime day, he said.

Falmouth can certainly do more to become a bicycling-friendly community, he added, by painting bike lanes and “sharrows” on the roadways and routes to schools. It is something of a catch-22, however, because the town will probably not take these steps unless there is a demand— and until people think it is safe to ride a bike on the road, there won’t be as much demand.

In its annual bid to promote bicycle commuting, the League of American Cyclists has declared May as National Bike Month, with May 16 to 20 as National Bike to Work Week.

In Falmouth, bicycling advocates will be observing Bike to Work Day on May 18, with free coffee, pastries, and information at two booths along the Shining Sea Bikeway.

Six steps… and beyond

So, to recap, there are six things you can do today, this week, or this month to green up your life: don’t buy something that you can’t reuse or recycle;  turn off unnecessary appliances and sign up for a free energy audit; throw away food scraps in a bin and attend a composting workshop for the next steps; trade in some of your meat for fresh vegetables;  take the bus, carpool, or bike to work or on your errands.

Anything else? Let us know how you celebrate Earth Day!

Are we flushing money down the toilet?

As someone who goes to a fair share of wastewater-related meetings, I wasn’t expecting to be blown away at last weekend’s Eco-Toilet Summit.

On a conceptual level, I felt I already understood the basics of composting human waste— hey, I do it every day with food scraps.

Adding one step through my digestive system to my garden seemed to make sense… from a theoretical point of view.

But after hearing about the range of eco-toilet options available, and a variety of perspectives from regular residents, the theoretical became possible.

What stopped making sense is the way we use—and view—the bathroom.

Saturday’s Eco-Toilet Summit was a one-stop shop for those interested in reducing household water use and recovering nutrients from our excretia to make fertilizer to grow food.

A mid-size Phoenix composting toilet

Curious residents flocked to the shrines of ecological design—a large blue Phoenix composting toilet, the Ecovita’s familiar white bowl with a tiny hole for urine diversion, and the diminutive, portable Pacto toilet—and took advantage of the friendly sales representatives to ask questions:

How do they work? Does it smell? How much would it cost to install?

Sponsored by a coalition of grassroots environmental groups, the afternoon was dedicated to learning more about modern ecological approaches to dealing with an age-old problem: how and where to dispose of our waste?

That is the $600 million question, as Falmouth considers ways to clean up decades of nitrogen loading to sensitive coastal embayments, and one which the summit’s sponsors hope can be answered with alternatives to centralized sewering.

I know. Maybe not everyone’s cup of tea. But for anyone who poops and pees, it might be worth it to hold your nose and pay attention.

Eco-logical justice

The go-to solution for the past several decades has been centralized sewering, which collects sewage, storm water, and graywater (laundry, shower, and dish water) in a network of underground pipes for treatment and eventual release back into the groundwater.

I won’t get into all the pro’s and con’s of sewering here, suffice to say that there are two factions of environmentalists doing battle in town: biologists who favor sewers as a proven way to keep nutrients out of the groundwater; and ecologists who view the cycle of nutrients as a “closed-loop” system and favor composting to pump n’ treat.

It’s a fascinating chapter in environmental history, as we discover how we are all responsible for the decline of eel grass and shellfish in our beloved harbors.

The debate also takes on an environmental justice perspective, as one considers the economic cost-benefits of sewering vs. composting or diverting our waste.

Eco-toilet panelists Abe Noe (Phoenix), Carol Steinfeld (Ecovita), Hilde Maingay (the Green Center) and former state rep Matt Patrick

For eco-toilet advocates, the solution to nutrient management lies in closing the loop between waste and resources.

With urine-diverting and composting toilets, the waste products are collected and pumped out roughly every six months, depending on the size of the household. With a compacting toilet, waste is packaged neatly into a plastic or biodegradable bag, which can be collected for compost or thrown out weekly with the garbage, just like regular diapers.

Storage from six months (for urine) to two years (for solids) removes pathogens from the waste, a process that may also break down pharmaceuticals and contaminants of concern.

A composting toilet or urine-diverting system takes advantage of biological processes to break down the nutrients in urine and feces to create potent fertilizer and carbon-rich humus, said Don Mills, a sales manager for the Lawrence-based compost toilet vendor Clivus Multrum.

A conventional wastewater treatment system uses the same process, but combines household waste with stormwater, requiring enormous amounts of energy to pump and adding heavy metals and pollutants to the mix.

Earle Barnhart, whose Green Center organization was the primary sponsor of the summit, noted that treating human waste as a resource could lead to the development of new industries. Whether collected and processed on-site or elsewhere, the compost and fertilizer could be sold and used to grow organic produce, he said.

Dollars and sense

For former state representative Matt  Patrick, the eco-toilet alternative would save residents millions in betterments and taxes to finance the sewer system. Going the sewer route, he warned, could force middle- and low-income residents to leave town.

I don’t think any of us want to live in a community that’s all wealthy, where middle class and low-income families can’t afford to live. But that might be one of the outcomes if we press forward with a conventional sewer system.

-Matt Patrick

According to Mr. Patrick, installing two urine diverting toilets in every home in the south coast watershed would amount to just 10% of the cost of sewering those neighborhoods.

(2 UD toilets + 2 UD urinals @ $1,500-$3,000/home)                    x 8,000 homes = $12-24 million

+ $175/year pump-out  x 8,000 homes = $1.4 million

x 10 years= $14 million

Grand total cost for 10 years installation & maintenance:

$26-38 million.

Not only would about 80 percent of the nitrogen currently leaching from septics be stopped in its tracks, but local plumbers and waste service industries would be employed by this system, Mr. Patrick said.

The cost for each alternative system varies depending on household needs, but the vendors estimated about $1,000 for a micro-flush urine-diverting toilet; about $1,100 for a compacting toilet, plus $200 a year for disposable bags; and up to $6,000 for a large composting toilet, not including installation and maintenance.

A three- to 12-watt fan is required to remove odors from the composting system, but Mr. Patrick noted that the electricity cost for such a system is less than one energy-saving light bulb.

The Falmouth precedent

One of the recurring questions from the audience was whether this innovative method of handling waste had been done elsewhere.

Mr. Patrick said that UD toilets are popular in Sweden. Don Mills of Clivus Multrum pointed out that Europeans, Americans, and Asians only stopped using “night soil” as fertilizer in the last century.

I might add that Africans are also composting their waste, providing low-cost sanitation as well as bananas, a source of food and income.

Hilde Maingay, of The Green Center, makes the case for eco-toilets as a means of achieving social justice

Faced with an almost overwhelming dilemma, Falmouth has a unique opportunity to set a precedent among coastal communities. Yes, it is scary to be the guinea pig—but how appropriate, given our world-renowned science community and ecological pioneer residents.

Money is relative to social justice and long-term stability. [Eco-toilets] could add more stability to communities and make them more socially just.

-Hilde Maingay, the Green Center

The Eco-Toilet Summit organizers are not expecting anyone to just take their word for it, however.

They are hoping for a study of these alternative systems, including an energy-use cost-comparison with a conventional system and the regulatory mechanism by which residents could install (and maybe even get loans for) an eco-toilet system of their choice.

The cost-benefit

Mr. Patrick is in favor of urine-diverting toilets, which sequester the high nitrogen content in urine while using small amounts of water to flush feces into a septic system.

He’s a fan because of the relatively low cost and high nutrient recovery. Given that the system only needs to be pumped periodically, the maintenance requirements are also pretty low.

Composting toilets are already approved by the Department of Environmental Protection and are widely used in Massachusetts, but urine-diverting toilets have yet to go through the permitting process.

While the jury is still out as to whether composting waste will remove the pharmaceuticals and other harmful chemicals, eco-toilet proponents make a good point that it is better to remove those “contaminants of concern” from the waste stream altogether, rather than combine them for centralized treatment.

Currently, most wastewater treatment plants lack the technology to remove the aspirin, caffeine, hormones, and pesticides from effluent anyway.

Even with an eco-toilet, septic systems would still be required to handle the household laundry, bathing, and dishwater, also known as graywater. The pollutants associated with those systems would not be addressed by an alternative toilet system either.

I’ve written at length about UD toilets, composting and compacting systems elsewhere on Under the Lens, so please click here if you are interested in the details.

Footnote: it’s in the report

For further reading, it’s interesting to note that Stearns & Wheler, the engineering design firm that developed a draft of Falmouth’s comprehensive wastewater management system, devoted a few pages to “waterless toilets” and UD systems in its 454-page report.

a. Wastewater flows and loads are reduced if properly designed and installed.

b. Water consumption is significantly reduced.

c. Minimal environmental concerns occur when properly sited and designed.

d. Composting toilets require minimal energy use.

e. Size of standard septic system can be reduced to treat only gray wastewater.

f. Routine maintenance is minimal and requires no special training.

As for urine diverting toilets, Stearns & Wheler lists the advantages:

a. Water consumption is reduced.
b. Minimal environmental concerns occur when properly sited and designed.
c. The nutrients in the urine could be positively recirculated in the environment by use as fertilizers.
d. The technology could decrease the nutrient removal costs associated with wastewater (less the urine component) at the WWTF.

Urine source separation toilets have the following disadvantages, according to Stearns & Wheler.

a. Existing biological and chemical technologies at WWTFs are not sufficient to treat concentrated urine. Additional facilities would need to be designed and constructed.
b. Homeowner renovation costs would include new toilets, plumbing, and urine storage facilities. Urine separating toilets are likely to be costly and lack decorative design options which may decrease homeowner acceptance.
c. Increased homeowner disposal hauling costs associated with two separate collection systems.
d. Septage hauling trucks may need retrofitted equipment to properly handle concentrated urine.
e. Technology works correctly with proper use. Proper use is limited to sitting on the toilet, meaning behavior modification for males.
f. Technology works correctly with proper maintenance, which includes removing urine scale that can block pipes over time and using certain cleaning agents which would not contaminate the collection tank.
g. Human urine use as an agricultural fertilizer may not be socially acceptable.
h. Not well suited to high seasonal community and tourist population.

Wes Jackson, founder of The Land Institute, at MBL's Lillie Auditorium

In order to solve humanity’s biggest crises—hunger, malnutrition, environmental degradation, and even climate change—farmers and ecologists need to get married.

That was the message Wes Jackson, founder and president of The Land Institute of Salina, Kansas, brought to Woods Hole last week.

In a room filled with local scientists and backyard farmers, one could imagine a harmonious marriage.

If only the two hadn’t gotten divorced in the first place.

Speaking at MBL’s Lillie Auditorium on Feb. 2, Dr. Jackson’s wisdom was disguised in his easy Kansas manner.

“We need a system with an ecological world view,” he said, resting his elbow on a bent knee at the front of the stage.

“We need to start where climate change began: agriculture.”

A geneticist-agronomist and author who has received a number of prestigious awards– including the MacArthur Fellowship in 1992 and the Right Livelihood Award in 2000– Dr. Jackson has dedicated his life’s work to developing perennial grains, including wheat, rice, sorghum, and prairie flowers.

Agricultural colonialism?

Since wheat was first developed as a domestic crop in 9000 BCE, farming has meant cultivating annual monocultures, Dr. Jackson said. But while great advances in civilization were made possible by the spread of agriculture, it also led to the destruction of the environment that supported it.

Wheat was the “pulverized coal of the soil. That’s where climate change had its beginnings,” he said. “If we were to eat, nature had to be subdued or ignored.”

Recognizing that scientific discoveries—including Copernican theory, Galileo’s discoveries, and Darwin’s theory of the evolution of species—would not have been possible if humanity had remained hunter-gatherers, Dr. Jackson pointed out that these advances were based on the “extracting economy” of various European empires, especially the British empire.

Whether people are mining for coal or engineering seeds to increase crop yields, there are consequences to this world view, he said.

With soil erosion in many parts of the world exceeding natural replacement levels and fertilizer runoff creating “dead zones” in places like the Gulf of Mexico, “we’re losing the stuff we are made of to the sea,” Dr. Jackson said.

Fifty years after Rachel Carson’s Silent Spring exposed the ecological threat posed by pesticides, the industry has doubled in size, he added. Though fertilizers led to the “green revolution,” the energy required to produce them outpaces the amount of calories created.

If only we would learn…

Humanity is operating on a “3.45 billion-year-old imperative” that causes us to seek out carbon-based resources to sustain ourselves, Dr. Jackson told the audience.

“There was never a need to practice restraint. It has to be something learned,” he said. “If we can save our soils, we can keep alive what we’ve learned on this long journey.”

Cultivating perennial poly-cultures can solve a number of agricultural headaches, from drought, pests, and the amount of work required to plow, plant, and harvest the crops each season, he said.

In partnership with researchers in China and Sweden, Land Institute researchers around the world are working on perennial varieties of the world’s three major major grains, rice, corn, and wheat– as well as oil-producing plants like mustard and sunflowers.

Dr. Jackson acknowledged the concept he and his colleagues are developing will not be popular with seed suppliers, and fertilizer, pesticide, and oil companies.

But even without millions in corporate and government funding, The Land Institute has been able to refute the arguments often made by pro-genetic engineering types and chemical corporations.

A paper published in 2008 by Land Institute researcher Stan Cox showed that perennial crops have the potential to  feed a growing, ever-hungry population without destroying nature.

In this vision, the “sustainable agriculture industry” finally ceases to be an oxymoron– and in fact, could provide the hope for greater food security across the globe.

Considering that in 2006, prices for basic grains jumped 80 % for wheat, 60% for corn, and a whopping 320% for rice, the world’s hungry need all the help they can get.

If the uprising in Egypt is at least partly due to rising food prices– in a country where people barely survive on $2 a day– it’s possible that revolutionizing agriculture could also lead to word peace.

The perennial promise

Unfurling an 18-foot poster comparing perennial wheat to its domestic sister species, Dr. Jackson pointed out that the perennial variety’s long root system can find water where the annual plant cannot.

Perennial wheat has been found to fix carbon in the soil and reduce nitrate and water losses typically incurred at each harvest.

Furthermore, its productive life span of five to 10 years means a heartier crop that can compete with weeds and resist pests, reducing the need for pesticides.

Perennial wheat strains developed by The Land Institute have only been able to produce 40 percent of the seeds of an annual variety, said Dr. Jackson, who estimated the perennial strain will require up to 50 more years of interbreeding to match–and eventually exceed– that level of productivity.

But it will likely be worth the wait. Lab tests have shown that flour made from perennial wheat has 40 percent more protein, 10 times more folate and lutein, and up to 600 percent more nutrients than traditional wheat flour.

Dr. Jackson’s books, including the 2010 Consulting the Genius of the Place: An Ecological Approach to New Agriculture, provide plenty of food for thought on the subject of sustainable agriculture, in which biologists and backyard gardeners may find common ground.

I wonder what would be served at the wedding.

But he is not stopping in Falmouth for long: shortly after Christmas, Febos will hit the road in his Rabbit, armed with nothing more than a camera, a laptop, and a tank full of vegetable oil.

Combining his interest in low-impact living with a quest to find other people who are setting that example, Febos plans to drive across the country in his vegetable oil-powered car.

With a binder of information as a road map, he plans to visit at least 35 sustainable projects in urban and rural locales, hoping to gain insight and inspiration into how society can design itself according to ecological principles.

In what may be viewed as a modern-day version of Jack Kerouac’s On the Road, Febos plans to blog his way across America.

I’m documenting the life process of living more sustainably and happily, while minimizing my use of resources and assessing my impact on the blog. The idea is to inspire people to see how others are making their lives more sustainable with fun, cool projects. That way people can see how they can make changes in their lives.

-Barry Febos

Creating, not consuming

For Febos, repurposing waste products into useful materials is a way of life—and a form of artistic expression.

His journey began in October with a “live-in” exhibition in a Baltimore gallery, entitled “Moving to Utopia: unpacking a quest for a more sustainable life,” a slogan that is also stenciled onto the side of the Rabbit.

Living in the gallery for a week, Mr. Febos depicted his planned journey through photos, drawings, maps, and video, while cataloguing his possessions and “auctioning off” the items he deemed unnecessary. He plans to do a version of this show in New Orleans, and another when he returns to Falmouth.

His previous art projects have included making notebooks out of plastic bags and paper that had been printed on one side, making windows out of glass bottles, and a hammock made of used fabric and plastic bags.

One man’s food is another man’s fuel

While working on community art projects in Baltimore, Febos started to get interested in the mechanics of biodiesel engines a couple years ago. He bought the Rabbit, already equipped with a vegetable oil conversion system built into it, and started imagining the possibilities.

“Having a vehicle that runs on veggie oil seemed like a way to creatively use other people’s waste,” he said.

Though diesel engines can run on straight bio-diesel, using discarded vegetable oil requires a few additional steps, said Febos.

First, one has to find a source of oil. Usually, restaurants and fast-food establishments have to pay to dispose of the used oil, and are only too happy to have someone take it off their hands, he said. A classified-type website, Fillup4free.com, is another source for finding free or cheap waste oil.

Once he collects 10 gallons to fill a separate fuel tank, the oil must then be filtered to remove any food particles or water.  Febos has constructed a simple filtration system using plastic buckets and fine-meshed cloth.

He plans to have several gallons of oil filtering while he drives—so as to avoid running out of fuel with no McDonald’s in miles.

Bio-diesel mechanics

One issue with a built-in conversion system is that diesel engines cannot start with vegetable oil, and the car must be warmed up completely before switching over to the bio-diesel source. Therefore, the Rabbit has a regular fuel tank for starting the car and flushing oil from the fuel lines during the last few miles of each journey, Febos said.

“The conversion system is not as good for driving locally. For a three- to four-mile trip it doesn’t really work,” he said.

Mr. Febos plans to take the southern route across the United States, where warmer temperatures should make the oil less likely to congeal. He said the Rabbit gets up to 50 miles per gallon while running on either regular diesel or vegetable oil.

In addition to getting an MPG that rivals hybrid vehicles, running a car on veggie oil benefits the environment in a number of ways.

According to the non-profit educational organization, NOLS, running your car on recycled veggie oil:

• Makes us more energy independent. As long as people eat French fries, there will always be an oil source. Plus, your tailpipe will give off the pleasant odor of fried food, instead of toxic fumes!
• Reduces our dependence on oil from foreign sources or environmentally sensitive areas.
• Does not release sulfuric acid (SO2) into the atmosphere, one of the main causes of acid rain.
• Reduces our carbon dioxide (CO2) emissions by 78%.
• Produces 48% less carbon monoxide, a poisonous gas, than regular diesel fuel.
• Creates 48% less asthma-causing particulate matter, and 80% less cancer-causing polycyclic aromatic hydrocarbons (PAH’s) than petroleum diesel.

Connecting the dots

The first stop on Febos’s itinerary is just a few miles from his parents’ home. Having received some guidance on biodiesel vehicles from Joseph L. Hackler, a member of the Alchemy Farm Neighborhood Association, Febos plans to start his blog with a post about the agricultural and renewable energy projects at Alchemy Farm, home of the former New Alchemy Insitute.

Other highlights of the journey will include the Germantown Community Farm in upstate New York, where a fellow Falmouth native, Kaya Weidman, is working on starting up a community radio station, WGXC.

He also plans to visit a shanty boat project in Providence, Rhode Island, where a group has created something like a floating ark, complete with a vegetable garden and chickens and ducks on board.

Farther south, Febos plans to visit intentional communities in Virginia and Tennessee, staying for a while in each place to blog and contribute to projects. He also plans to visit the Project M Lab’s Rural Studio in Greensboro, Alabama, where designers tackle problems and find solutions for poor communities.

“I’m still learning. I want to see and participate in what people are doing, so that later I’ll have the resources to make things happen,” Febos said.

Eco-logical pioneers

John Todd, co-founder of Hatchville's New Alchemy Institute, surrounded by EcoMachines

In the 1970′s, a group of forward-thinking oceanographers and engineers sequestered themselves on a few dozen acres on Hatchville Road. Their dream: to design a self-sustaining way of living, limiting their consumption to what they could grow or make themselves, and returning any waste to the natural cycle. This was sustainability before the word turned into a marketing term.

In addition to growing their food in a bio-shelter and living in super-insulated buildings, one of the New Alchemy founders devised a way to turn what is traditionally called “wastewater” into a resource.

Dr. John Todd’s vision adapted nature’s principles to create the EcoMachine, a surprisingly simple design that effectively breaks down the harmful microbes and complex nutrients in wastewater.

A homegrown industry

Today, Dr. Todd’s designs are marketed across the US and the world by his son, Jonathan Todd, through the Woods Hole company, Todd Ecological Design. From China, to Hawaii, to the Bahamas, the likes of Coca Cola Company, Tyson Foods, and the Four Seasons are integrating EcoMachines into their wastewater treatment strategy. While the systems work well on a campus like the Omega Institute, they have also been adapted for the cities of Eugene, Oregon, and Providence, Rhode Island.

Much like a traditional wastewater treatment system, an EcoMachine employs aerobic and anaerobic bacteria to treat water to a very high standard– but without relying on chemicals like chlorine. What’s more, the system is designed so that water may be reused (not for drinking!) to flush toilets, water house plants, clean clothes, and so on.

The beauty of simplicity

Many people mistake an EcoMachine for a tropical greenhouse

Traditionally housed within a greenhouse or a combination of exterior constructed wetlands, a robust ecosystem is created between the plants, microbial species and distinct treatment zones. Within the Eco-Machine, all the major groups of life are represented, including microscopic algae, fungi, bacteria, protozoa, and zooplankton, to snails, clams, and fishes.

Some EcoMachines are actually intended for aquaculture applications, wherein shellfish feed on the nitrogen in the water, and fish feed on the algae. Dr. Todd’s vision has been applied so that commercially valued trees, shrubs, and even edibles such as mushrooms, can be grown within the system. In short, this self-contained ecosystem that turns a problem into a solution.

Spreading the word

Inspired by Dr. Todd’s vision, local documentary filmmaker Kristin Alexander produced a short documentary, called Green EcoMachine. With this 11-minute film, she has exposed audiences of the Woods Hole Film Festival to the Awareness Festival in Los Angeles to the possibilities of sustainable wastewater treatment.

Alexander’s work with ecological designer Dr. John Todd will be showcased at the National Design Triennial: Why Design Now? at the Smithsonian’s Cooper-Hewitt National Design Museum in New York City, opening on May 14.

At a screening of her film at Cinema Politica last Friday, several members of the audience questioned why Falmouth– and other Cape towns– do not have access to the EcoMachine. They wondered what impact household or neighborhood EcoMachines would have on the region’s estuaries, which are steadily declining due to nitrogen pollution from septic tanks.

The only response I can give you here is to bring these questions to the Comprehensive Wastewater Management Plan Review Committee, a convoluted name for the town board responsible for coming up with a way to tackle the problem. The committee meets every Tuesday at 5 PM at Town Hall. For those who can’t make it, the meetings are televised by Channel 13 and there is also an online forum. A big meeting on design alternatives is scheduled for May 27 at 7 PM at the Morse Pond School.
