    Yadkinville, N.C. -- Loyd Bryant used to pump manure from his 8,640 hogs into a fetid lagoon, where it raised an unholy stink and released methane and ammonia into the air. The tons of manure excreted daily couldn't be used as fertilizer because of high nitrogen content.

    The solution to Bryant's hog waste problem was right under his nose - in the manure itself.

    A new waste-processing system - essentially a small power plant - installed on his 154-acre farm uses bacteria to digest the waste and burns methane to produce electricity. It also converts toxic ammonia into forms of nitrogen that can be used as fertilizer for more profitable crops.

    A project that converts methane from a Will County landfill into energy that can power 4,000 homes and generate more than $1 million annually for the county is now online.

    The $9 million methane-gas-to-energy plant at the Prairie View Recycling and Disposal Facility is a joint partnership between the county and Waste Management, which handles waste disposal for many local communities. The county contributed $3.1 million in stimulus dollars to construct the plants and connect to the ComEd power grid.

    Got a new computer or TV for Christmas and want to get rid of your old one? Or is that old 19-inch dinosaur still collecting dust on its metal cabinet in your basement?

    Disposal of your old electronics got a bit trickier in the new year for many New Yorkers.

    Under a new law that took effect Jan. 1, both private and public haulers are prohibited from collecting electronic waste, except for recycling. Haulers are now prohibited from disposing e-waste at landfills and waste-to-energy facilities in New York.

    'Tis the season of gadgetry, and one of many innovations emerging on the consumer market is electronic textiles. These e-textiles, or "smart" textiles, integrate electronics capable of collecting and sending information into the fibers of clothing. Imagine: a motherboard woven into a holiday sweater. An antenna in your skullcap.

    Imagine, also: soaring mountains of e-waste, as the United Nations has described the 50 million tons of electronics disposed of every year. Imagine how e-textiles will contribute to these mountains, their obsolescence a factor of both advancing technology and the rapid cycles of seasonal fashion.

    The standard model is to invent first and consider environmental consequences later. Equally standard are calls to get it right next time -- to be proactive for the next technological innovation.

    An article published recently in Yale's Journal of Industrial Ecology identifies e-textiles as the next "next time," undertaking the first analysis of their end-of-life implications. The results predictably illustrate that reliance on business as usual won't do the trick.

    Anthony Pratt seeks $300m from government to flick switch on waste-to-power scheme

    by: Damon Kitney From: The Australian November 23, 2011 12:00AM 

    THE Pratt family's $3 billion Visy paper, packaging and recycling empire is seeking federal government support to help bankroll a revolutionary $300 million project to turn household garbage into energy that would generate 3000 jobs across the economy.

    The project would involve construction of a $200m waste-to-energy plant, the first of its type in Australia, designed to generate 75 megawatts of electricity that would be sold into the electricity grid or directly to third parties.

    Fuel for the plant would come from waste transfer stations or landfill sites in capital cities, where Visy is planning to spend $100m to build a number of so-called pellet plants to shrink garbage into fuel for the waste-to-energy facility.

    The garbage will be dehydrated to the size of a cork, which has the burn value of low-grade coal, and then fed into the clean energy plant to turn into energy.

    Visy is seeking $100m for the project from the Australian Renewable Energy Agency, or ARENA, the new independent statutory body established to provide financing assistance for projects that strengthen renewable energy and energy efficiency technologies.

    Plant would convert waste to energy

    A new Eugene company wants to use farm and food byproducts to make gas and generate electricity

    A Eugene company is proposing to build a bioenergy plant off Highway 99 near Junction City that would turn waste straw, vegetable and fruit waste, and manure into electricity. The plant would compost the waste and burn off the resulting gas to generate electricity.

    The plant, proposed by Green Lane Energy Inc., is the topic of a public hearing to be held by the state Department of Environmental Quality on Tuesday.

    The DEQ is proposing to issue a solid waste treatment facility permit for the project.

    “This operation is unlikely to pose impacts to the environment and the public health,” the DEQ analysis concludes in recommending approval. “The operation beneficially utilizes the ‘waste’ materials to generate ‘renewable green power’ and reduces the waste stream into the environment.”

    Green Lane is headed by Dean Foor, a Eugene engineer and consultant with expertise in biogas plants. The plant would be built on several acres of farmland on the east side of Highway 99, about halfway between Eugene and Junction City.

    The land is owned by members of the Posner family, who also own Lane Forest Products, a Eugene mulch, compost and landscaping materials firm.

    The state is proposing to let the facility accept dairy manure, ryegrass straw, used cooking oil and grease, food processor residue and food waste from companies and homes.

    Efforts in Eugene and elsewhere to collect and compost food wastes, rather than dump them in a landfill, have been increasing steadily. Eugene earlier this year launched a program for the collection of food waste from commercial establishments for composting. Lane Forest Products and Eugene-based Rexius are taking the food waste and using it in compost.

    It was not immediately clear whether the Green Lane Energy plant would be using Eugene’s food scraps.

    Foor and the Posners did not return phone calls seeking comment.

    The plant would have a waste material intake and storage area, concrete tanks where material would be mixed and would decompose and produce methane gas, and a burning unit that would use the gas to generate electricity, according to the DEQ’s analysis. The electricity would be fed into an existing nearby line in the electric grid. The plant would generate some liquid and solid wastes that would be sold as fertilizers or compost, the DEQ analysis said.

    The state’s analysis states that the plant would operate on average more than 23 hours a day, seven days a week, and that much of the daily operation would be automated.

    The bioenergy plant would sit next to an existing Lane Forest Products yard-waste compost plant, where Junction City’s leaves and other yard waste are composted, according to the DEQ. That plant has been in operation since 2006.

    Details of the bio­energy plant undefined including its cost, how it would be funded and who would buy the power undefined were not immediately clear.

    Coral Springs is preparing to take its recycling program up a few notches and will consider a recommendation by its consultant to provide an economic incentive to single-family residents.

    The city hopes to achieve a 75 percent recycling rate by 2020, but there is quite a distance to be traveled before it reaches its goal. According to a study conducted by the city's waste consultant, HDR Engineering, the recycling rate of single family homes in 2010 was 9.1 percent while it was 5.7 percent in multifamily homes. The commercial recycling rate in the city was 22.6 percent.

    The city's solid waste and recycling strategic plan, which was established in 2010-2011 after the legislature asked state and local government bodies to ensure that they achieved the 75 percent goal, will be implemented in three phases. At a recent city commission meeting, officials were given an idea of where the city stands today and also briefed about the steps that are needed to achieve the 10-year goal.

    ALBANY, N.Y. undefined Environmental groups are pressing state regulators to reject a petition seeking renewable energy subsidies for trash-burning power plants, saying the incinerators are big polluters that destroy paper, plastic and other materials that should be recycled instead.

    The Public Service Commission is expected to rule on Covanta Energy's petition at its meeting Thursday in Albany. Covanta, based in Morristown, N.J., operates 44 energy-from-waste plants in the United States, including seven in New York.

    Covanta has asked the PSC to add trash burning to the list of renewable energy technologies eligible for state subsidies. At a news conference Tuesday, the New York Public Interest Research Group and several other environmental organizations said they've asked the commission to reject Covanta's petition, saying incinerators generate air pollution and toxic ash.

    Covanta spokesman James Regan disputed the groups' claims, saying the company presented evidence to the PSC that waste-to-energy plants using the latest technology are cleaner than some sources of energy eligible for subsidies. The petition only applies to new plants, not existing ones, he said.

    In a report released Tuesday, the Global Alliance for Incinerator Alternatives, a coalition of environmental groups, said the incinerator industry is pursuing a strategy across the nation seeking clean-energy subsidies. The report said most federal energy subsidies that benefit trash incineration are intended to foster the development of renewable energy sources such as wind, solar and small hydroelectric plants.

    From: "United Utilities turns human waste to energy at Plant," BBC News, August 22, 2011

    Human waste is being turned into energy in a multimillion-pound project in Lancashire.

    United Utilities is converting a by-product of waste water at its Blackburn plant into gas.

    The company is using the method to generate about 15% of the power it uses in its operations - equal to the power consumed in Burnley each year.

    The power generated helps run the sewage treatment works next to the United Utilities plant.

    The plant also exports highly nutritious fertilizer to agricultural land across east Lancashire for farmers free of charge.

    'Sustainable power'

    The method uses biogas, which is produced when waste water sludge is broken down by microbes in a process known as anaerobic digestion.

    Steve Mogford, CEO of United Utilities, said: "The plant can process up to 168 mega-litres of sewage each day, which arrives from other United Utilities sites in a 15-mile radius, and includes industrial waste from the Inbev Brewery and the local BAE Systems operations.

    "The power generated helps run the adjacent sewage treatment works."

    He added: "We already use AD technology to treat sewerage sludge and generate electricity at a number of our large treatment plants across the North West.

    "Blackburn is the first in East Lancashire to use a sustainable power supply to run its heating and machinery."
