For this simple animation describing just how simple it is to build your own biogas digester Building real digester is about as easy as building a digital one in sketchup -- it really is just two plastic barrels, one inverted inside the other, with three pipes -- one to get the food in, one to take the liquid fertilizer out and one at the top to deliver the gas to your cookstove or generator. 1000 liter tanks should get you about 2 hours of cooking gas a day if you live in a warm climate. As shown, we intend to use psychrophilic bacteria at the bottom to increase cold weather production. The process is very simple
located on campus of The Ohio State University. Dr. Li's research focuses on biomass feedstock logistics; biological and chemical conversion of biomass and processing waste to fuels, chemicals, and polymers; and algae grow for production of fules and bioenergy.
Using plants rather than oil or coal to produce fuels and chemicals could play an essential role in reducing the world's dependence on fossil fuels, according to a group of scientists from the UK and the USA writing today in the journal Science.
Biomass Magazine is a monthly trade publication tailored to serve companies and organizations engaged in producing or utilizing biomass power and heat, advanced biofuels, biogas, wood pellets and biobased chemicals. In addition to policy, regulation, project finance, technology and plant management, the publication maintains a core editorial focus on biomass logistics: generating, cultivating, collecting, transporting, processing, marketing, procuring and utilizing sustainable biomass.
