ANAEROBIC DIGESTER SERVICES INDUSTRIAL GENERATORS

BioCycle September 2006, Vol. 47, No. 9, p. 48

Waste Management's new Anaerobic Pretreatment Center receives liquid waste streams with high COD and fats, oils and grease.

COMPATIBILITY OF DIGESTION AND COMPOSTING

BioCycle September 2006, Vol. 47, No. 9, p. 42

Biogas production strips out the odorous VFAs that are problematic to composting, and converts them directly into biogas energy, for which they are biochemically ideally suited. The resulting residue is more readily - and less odorously - compostable.

Minneapolis, Minnesota
UNIVERSITY PROBES WAYS TO
CONVERT BIOMASS INTO BIOPRODUCTS
The Sixth Annual BioCycle Conference on Renewable Energy From Organics Recycling in Minneapolis, October 30 - Nov. 1, 2006 (see pages 15-17) will discuss processes that convert biomass into bioenergy and bioproducts. Many of these studies are underway at the University of Minnesota. As described by Todd Reubold of the University's Initiative for Renewable Energy and the Environment (IREE), the processes when commercialized will: Develop technologies for utilizing underused biomass; Provide a scientific assessment of energy production; Increase use of agricultural and forest

BIOCYCLE'S BRIDGE TO A RENEWABLE FUTURE

BioCycle September 2006, Vol. 47, No. 9, p. 4

THE September 9, 2006 issue of The Economist featured a special report on climate change. A conclusion in the opening commentary is that “while the science remains uncertain, the chances of serious consequences are high enough to make it worth spending the (not exorbitant) sums needed to try to mitigate climate change.” Further into the report, an article on “Where To Start” has the subtitle,
