Hi All,
If the solid waste comes in mixed and not with the organics source separted they can be contaminated by anything that was in the original solid waste. Heavy metal contamination comes to mind, particularly mercury, lead and zinc. I would also ask about the energy source for drying and pelletizing the solid waste. That could make it a zero sum or negative sum proposition. Organics in a solid waste stream can be very wet. Is there any penalties in the contract if 60 tons of pellets are not delivered?

Biodiesel plant to use trash as fuel
MARCUS, Iowa (AP) -- One man's trash is another man's -- energy source?
Soy Energy, a company that plans to build and operate the plant, will use
pellets of biomass from a local landfill as its primary source of steam and
thermal energy, said Mark Buschkamp, executive director of Cherokee Area
Economic Development.
Experts say trash is a novel source of energy for a biofuels refinery.
Company officials believe using biomass will offset the high costs of
natural gas.
The biomass will come from Cherokee County Solid Waste, a three-county
landfill near Cherokee, Buschkamp said.
The landfill will build a facility to collect materials, such as paper,
cardboard and foods, which will be turned into pellets for use by Soy
Energy.
The plant will require 60 tons of pellets a day.
Construction on the plant, to be located on 37 acres between Marcus and
Cleghorn in northwest Iowa, is expected to begin by the end of the year with
a planned opening for the end of 2007.
An announcement on the $52 million investor-owned project was expected
Wednesday.
Plans also include construction of a soybean-crushing plant, expected to be
completed by 2010.
