Good one - another contender in the "biomass" category. This is
controversial since the municipal solid waste stream can generate some very
nasty toxic emissions, and the pyrolysis process itself can generate
prodigious amounts of deadly carbon-monoxide.
When it comes to managing toxic wastes, I think "utility scale" processes
have an advantage over small-scale distributed applications. I'm a lukewarm
fan of waste-to-energy or "refuse derived fuel", but the economics are not
too good, especially when byproducts are managed meticulously.
A more viable loop is methane gas from sewerage, landfills, and large
agricultural feed-lots.
