Happy Friday BESTers,
   There are many strategies for developing food waste-to-biogas 
projects.  This article discusses one possibility they're looking 
at in the UK to sending food waste to the sewer via sink-mounted 
disposals.  At the treatment plant an anaerobic digester would 
treat both the food waste and sewage, killing two birds with one 
stone by producing biogas from both waste streams.  This could be 
a good strategy for capturing food waste generated throughout the 
community where individual digesters may not be pratical.  In the 
US where most homes already have disposals, the switchover would 
make even more sense.  In fact some high volume sources 
(restaurants, grocery stores) are already sending their food waste 
to the sewer.  Why not make biogas, rather than expend energy to 
treat this waste?
