[GreenYes] Re: RDF burner promoted to "save" paper recycling plant (Minneapolis)


Looking at it from a homemaker's perspective of how I save energy and
time, maybe this is something to look into.

When I boil my soup or use my rice cooker, I always try to heat up or
steam another dish. From there you learn that not all food need the same
degree of heat to cook. So, why can't the paper and steel recycling
industries work together. Work on the basis that steel needs more energy
to breakdown compared to paper. Also, oil palm fibre have been used to
produce biodegradable packaging. The packaging breakdown with moist and
heat to become fertilizer.

What the players of these recycling industries should do is work
together to share heat resources in their processes. To make it happen,
funds will be needed I am sure.

Need green fund? Look for "birds of a feather".
