There has been a lot of resistance to waste to energy (WTE) systems from environmental groups because of the older technologies which fundamentally burned the trash and used to heat to boil water, the steam then generated electricity. New technology no longer burns the waste, but gasifies it. Heat in the absence of oxygen gasifies what is inside. The gases are used as a fuel for the production of electricity. The technology is simple and available. Emissions are within standards of federal and local regulations, but there is still a reluctance to implement. So the opportunities are going overseas.
Ceres Associates is promoting the concept of WTE as best we can. We have generated some interest in the US, but permitting moves very slowly here, and any such projects will be quite a while in coming. However, in other countries the demand for WTE systems is starting to crescendo.
It is a green-house gas eliminating process. Methane is generated from landfills, and methane is one of the most dangerous of green house gases. Methane is consumed in most gasification systems. Landfill space is saved, groundwater is saved, air quality is enhanced - a lot of good happens when WTE systems are employed - not the least of which is energy generated reducing the impact of petroleum products on the environment.
One more thing, most WTE systems are very effective at destroying most hazardous wastes. This is one other small benefit.
