LEGISLATURE CONSIDERS BILL TO SET GOAL OF 50 PERCENT RECYCLING BY 2009
Many factors are working together to “make us feel pretty optimistic that we’re going to see an increase in recycling,” says Deputy Director Sue Inches of the Maine Planning Office. Markets and prices for recyclables are strong, as the Maine legislature assembles a bill to achieve a 50 percent recycling goal by January 1, 2009 – and also reduce MSW generation by five percent. Other factors noted: Recycled material collection has jumped 200 percent in the last 15 years; the state has three pilot composting programs to study food waste collection and is generally promoting composting; C&D companies in southern Maine are expanding materials recovery; and there’s more interest in developing regional programs. According to George McDonald of the state Planning Office, Maine is conducting a financial study of 50 municipalities to evaluate solid waste management costs – with much attention to the impact of recycling on lowering those costs.

USING FOREST-DERIVED BIOMASS TO CREATE RENEWABLE ENERGY CREDITS
Forest thinnings – mostly small wood chips that are a by-product of forest fire mitigation activities – are being used to create cleaner energy through a partnership of the Aquila, Inc. company in Canon City which owns a generating station and the U.S. Department of Energy. The forest thinning operations to reduce the threat of wildfire are being done by landowners, state and local governments, and the U.S. Forest Service. Thinning typically results in piles of slash and burn that are generally burned in place as a disposal method. ‘We hope that the success of this project will encourage more forest thinning work to be conducted and protect our forests from the damage and impact of wildfires,” says Rick Grice, chairman of the Colorado Governor’s Office of Energy Management and Conservation.
The W. N. Clark Generating Station, owned by Aquila, will use the thinnings to replace part of the coal currently processed for fuel. Substituting the woody biomass in the fuel mix reduces sulfur oxides, nitrogen oxides and carbon dioxide emissions. The plant plans to sell the environmental benefits from the project by issuing Renewable Energy Certificates (RECs). RECs represent the environmental attributes of renewable energy generation and can be sold in a voluntary market beyond the boundaries of a utility’s service area. “They expand the green power market and make it possible for people to support clean energy options,” adds the Governor’s Energy Management office.
MANDATORY RECYCLING LAW SETS 60 PERCENT TARGET BY 2010
With a nationwide recycling average of 27 percent, according to the BioCycle State of Garbage in America survey in 2003, Seattle’s rate of 40 percent stands up well. But not well enough, since the city’s mandatory recycling law took effect this year. The new goal is 60 percent by the end of the decade. Starting in 2006, reports the Associated Press, people in single-family homes won’t get their trash picked up if they dump “significant amounts” of recyclables in their trash, defined by the city as more than 10 percent by volume. Owners of apartments, condos and businesses will face $50 fines. “So far, city officials say few people have complained. Most calls have come from people wondering how to comply with the new standards,” notes the AP. Seattle has budgeted $1.5 million for a three-year education campaign that began last year with such messages as “Why waste a good thing?”
HOW TO KEEP 800 MILLION BEVERAGE CONTAINERS/YEAR OFF WHITE SAND BEACHES
According to Hawaii’s Health Department, about 800 million beverage containers are sold in the state annually. With help from a new bottle bill that charges a nickel per can or bottle, state officials hope the program will keep 80 percent out of the waste stream (and the sand). Two leading recycling firms that have been contracted by the state estimate that more than five million cans and bottles were redeemed the first week after the bill’s enactment. In states with deposit programs, about 490 bottles and cans per person are recycled on average each year, while it’s about 191 in nondeposit states, reports the organization Businesses and Environmentalists Allied for Recycling.

METHANE RECOVERY AT WASTEWATER TREATMENT PLANT WINS CITY SPECIAL AWARD
“Operating expenses at our wastewater treatment plant have remained stable at a time when the price of electricity has risen over 70 percent,” notes Palm Springs Mayor Ron Oden. Conversion of methane to electricity has reduced costs by nearly $80,000/year. The city in partnership with Veolia Water North America (which has been operating the treatment plant since 1999) received the Outstanding Achievement Award last month for Public-Private Partnerships from the U.S. Conference of Mayors. Veolia Water acquired two microturbine generators through a grant program from the Southern California Air Quality Management District to generate electricity from the methane gas produced from wastewater treatment. The company also manages distribution of Class A biosolids produced at the plant as well as delivery of effluent for irrigation.
TRANSFORMING POTATO CULLS INTO HIGH-VALUE PRODUCTS
Of the five million tons of potatoes grown by farmers in Washington State, about 15 percent wind up as culls because they do not meet minimum size, grade or quality standards. Culls are often sent on for further processing – or added to compost piles. Now, reports the American Society of Agricultural Engineers’ publication, Resource, Shulin Chen of Washington State University’s Biological Systems Engineering Department is using cull potatoes and wastewater from potato processing to make chitin, chitosan and lactic acid.
The second most abundant polysaccharide in nature, chitin and its derivatives can be used for clearing wastewater as well as in manufacturing cosmetics and in medical applications. Lactic acid is used as a food additive and in development of polylactic acid to make biodegradable plastics. As the economics improve for processing, the technology could reduce the environmental impact of potato waste and wastewater. Chen’s e-mail – firstname.lastname@example.org.

TURF TOPDRESSING WITH COMPOST CUTS FERTILIZER EXPENSE BY TWO-THIRDS
According to a public works staff person at Mass Development, the cost of topdressing 40 acres of athletic fields with fertilizers and chemicals dropped from $75,000 in 2001 to $28,000 last year as a result of using 1/2-inch minus compost. To prepare fields, he core aerates in four directions then spreads 1,000 cubic yards of compost from an Agresoil site in Ipswich, Massachusetts at a rate of 25 cubic yards per acre. Also water usage dropped from 3 million gallons per year to 0.6 million gallons as a result of the compost applications. Sums up Mike Cabral of Mass Development: “We still apply our preemergent and broad leaf controls in the spring and our grub control in the summer, but because of the quality of the fields, we are considering reducing or altogether dropping our chemical applications, which will be another huge cost saving. The fields at Devens are heavily used and have never looked better.”
