[Gasification] biodigestion- gassificaiton or incineration

[Roger Samson]

One of the most innovative waste recovery systems is the wet-dry system
being piloted in Canada in Guelph Ontario.

Not sure if there is any use of Dispose-als in eastern Canada. I have never
seen one installed in a kitchen in eastern Canada.

Dispose-als, in many areas here, are still prohibited by local by-laws,
despite places like New York with its antiquated sewage system now
encouraging use of disposers through tax-incentives; and despite
jurisdictions in the U.S. that now mandate disposers in all new
construction.  I don't know about the amount of general use of disposers
here, I'll find out.

The regional government here claims increased use of disposers will overtax
the sewage treatment plants.  I said if that's the case, they need to be
enlarged or replaced anyway.  It falls on deaf ears - they are determined to
use the green cart system for collecting organics. The numbers used to
justify organics collection are based on the entire population of our
region, which includes all those already involved in home-composting as a
result of an amazingly successful home composting program. 

The sludge from the sewage treatment plant would be greatly improved with
the inclusion of sink waste, and would improve the end product that can be
spread on farm fields, however, the way development is eating up local
farmland, not to mention a large area that has to be excluded from receiving
sludge material due to its already high metal content, gasification or
incineration seems a more logical way to go.
Gasification and incineration are not currently looked upon with favour by
our provincial government, but at the same time our local government hasn't
made an application.
