waste output from one of the large feedlots near Lethbridge, Alberta. Methods
currently used to process manure produce some methane.

A plant on the
outskirts of Lethbridge has been proposed to process manure and other wastes
for energy. According to the company brochure, an anaerobic digestion process will produce
biogas. This biogas consists of 60 to 70% methane and 30 to 35% carbon
dioxide. It will provide fuel for three 1 MW generators which will supply
electricity to the Alberta grid and thermal energy to consumers.

The company
anticipates greenhouse gas reduction credits may be earned through
eliminating the methane emissions from
existing processes.

This plant is in
my backyard. I intend to keep a watch on
it.
