New ePack helps convert waste heat into electricity

by Isaiah Boone

In a recent article posted by Biomass Magazine, Orcan Energy AG highlights the effectiveness of its ePack product at a biogas plant in the United Kingdom. The ePack is a device that converts waste heat into electricity, and Shropshire Energy, the owner of the biogas plant, purchased 5 units to use at the facility located in Littleport, Cambridgeshire. The ePacks have helped to significantly reduce the carbon footprint of the plant while also providing it with a reliable source of additional energy. The ePacks have been particularly useful as Shropshire works closely with a neighboring mushroom farm which has reaped the benefits of the ePacks as well. Continue reading

Our Future in Feces: Vehicles Fueled by Biomethane

by Briton Lee

The British company Geneco has begun implementing prominent buses with a cartoon graphic detailing its power source: human waste. The concept of using waste to produce fuel is not novel, and is termed biomethane or renewable natural gas (RNG). It is most commonly used to power vehicles. The biomethane is collected from sewage treatment plants that process human waste while producing methane and carbon dioxide as byproducts. Typically, the resulting gases are simply released into the atmosphere, with plants in Oslo, Norway producing and releasing approximately 17,000 tons of carbon dioxide a year (Demerjian 2009).
