DIG-L: Anaerobic digestion

["Michael Chesshire" <greenfinch@burford.co.uk>]

Dear all,

My name is Lisa Pritchard and I currently work for a company called
GreenfinchLtd based in Shropshire, UK.  Our demonstration plant is a 20m3
anaerobic digester which treats  5-7 tonnes of source-separated household
kitchen waste (biowaste) each week  from approximately 1500 households.  

One of our objectives is to recycle and reuse of by-products of the AD
process.  This does not include agricultural land application.  As you
know regulations are getting tighter so we do not want to rely on land
application to reuse the nutrients effectively.  Hence we are reusing our
by-products through various processes including aquaculture and
vermiculture.

Our digester is mesophilc. Do you see any clear advantages for running our
digester at thermophilic temperatures, bearing in mind our climate and
need to reuse all by-products?

Thankyou and look forward to any replies,

Lisa Pritchard
