Sugar, not oil

27-Mar-2014 - No more oil – renewable raw materials are the future. This motto not only applies to biodiesel, but also to isobutene, a basic product used in the chemical industry. In a pilot plant researchers now want to obtain this substance from sugar instead of oil for the first time. And in order not to ...

'Wired microbes' to generate electricity from sewage

Interdisciplinary team creates 'microbial battery' driven by naturally occurring bacteria that evolved to produce electricity as they digest organic material

19-Sep-2013 - Engineers at Stanford University have devised a new way to generate electricity from sewage using naturally-occurring "wired microbes" as mini power plants, producing electricity as they digest plant and animal waste. In a paper published in the Proceedings of the National Academy of Sciences, ...

Biogas Plant Markets boom Worldwide in Municipalities, Industry and Agricultur

The worldmarket is about 2 billion euro in 2006 and expected to increase over 25 billion euro by 2020 But the competition is growing fast too. The key is the knowledge in biotechnology, molecular science, nano-bio-it convergence. (helmut kaiser)

19-Sep-2007 - Helmut Kaiser Consultancy released a study about the markets for biogas plants worldwide. The worldmarkets for Biogas and Biogas Plants increase since some years with 20 to 30 percent depending on the country. Germany as a technology leader reached in 2006 about 700 million euro with 400 ...
