Duke Energy to buy power from swine, poultry waste.

A new facility that captures methane gas to generate renewable electricity will be built in North Carolina Duke Energy, a sustainable electric and gas company that serves 7.3 million customers in the midwestern and southeastern United States, plans to purchase swine and poultry waste output from a facility planned for North Carolina – using the captured methane gas to generate renewable electricity at four power stations. Carbon Cycle Energy will build and own the facility, which is to be located in eastern North Carolina, although the exact location of the facility has not yet been announced. "It is encouraging to see the technological advances that allow waste-to-energy projects in North Carolina to be done in an environmentally responsible and cost-effective manner for our customers," said David Fountain, Duke Energy president -North Carolina. Under North Carolina's Renewable Energy Portfolio Standard (REPS), Duke Energy companies must meet specific compliance targets for swine and poultry waste. Duke Energy is already buying electricity generated from other facilities in the state. "We are pleased to partner with Carbon Cycle Energy to help meet our compliance objectives," added Fountain. "The gas from this project will generate carbon neutral electricity compared to the emissions that would result if the waste was left to decay naturally." Expanding the utility's renewable energy output, the captured methane will be treated, injected into the pipeline system and used at four Duke Energy plants in North Carolina. Under a 15-year term, Carbon Cycle Energy is expected to produce more than 1 million MMBtus of pipeline-quality captured methane a year. Duke Energy should yield about 125,000 megawatt-hours of renewable energy a year – enough to power about 10,000 homes for a year. The renewable energy credits (RECs) generated annually by the effort will help satisfy state mandates. contributed by wattagnet.

Poultry, pig manure used to produce energy in Chile.

Researchers at University of Concepción use waste to produce biochar and thermal energy Researchers at the University of Concepción are using the solid waste from poultry and pigs in the region of Bío Bío in central Chile to produce biochar and thermal energy. Professor Cristina Muñoz and Cristina Segura are exploring the technical and economic issues of using strong heat – pyrolysis – to recovering the energy locked up in organic waste from poultry and pig farms to produce biochar and energy. The process appears to be a green option for the treatment of materials that would otherwise have the potential to add to greenhouse gas emissions or groundwater pollution. Segura explained that large quantities of organic waste – slurry, manure, bedding materials, feathers and spilt feed – are produced by the region’s poultry and pig farms. The pyrolytic process results in a carbon material known as biochar and thermal energy in a safe, environmentally friendly and cost-effective way, say the researchers. Due to be completed in October this year, the project is funded by the Regional Government of Bío Bío. Muñoz explained that the first aim of the project has been achieved, namely to obtain a homogeneous and marketable material. Now, the biochar is being evaluated by the University as a soil improver for a wide range of horticultural applications. contributed by wattagnet.

WASTE MANAGEMENT AND POWER GENERATION.

Waste management is a global issue with developing countries having the biggest task.The management technique varies as different methods are used to prevent the environmental pollution and health hazard attached to this menace. The generation of electricity from the waste is a possible route,but the methodology and cost implication has always been an issue; see how a minimal investment in a biogas plant can generate power ,save the environment and generate revenue.See this

THE GEKO BRA!!! # ANIMAL INSPIRED FASHION.

A gecko's toe consists of a microscopic hierarchical structure of stalk-like setae - 100 microns in length, 2 microns in radius. From individual setae, a bundle of hundreds of terminal tips called spatulae - approximately 200 nanometers in diameter at their widest - branch out and contact the climbing surface. These hairs create an electrostatic force known as Van der Waals. It causes neighbouring molecules to be attracted to each other. Although very weak, the effect is multiplied by thousands of tiny hairs that cover a gecko's toes, allowing them to stick firmly to surfaces.
