Global waste-to-energy systems about to ramp

By | December 21, 2010, 3:31 AM PST

Waste-to-energy plants, which take municipal solid waste and produce electricity and heat, are about to pick up globally with global revenue surging by 2012.

According to Pike Research, the waste-to-energy (WTE) market will see global revenue increase from $3.7 billion in 2010 to $13.6 billion in 2016.

WTE systems address a few key issues notably landfill heaps that ultimately become environmental issues. Thermal WTE systems will still dominate with 93.2 percent of the market over the next six years. So-called biological systems will be 6.8 percent of the market.

There are more than 900 thermal WTE plans globally—most of them using combustion. In a nutshell, WTE plans incinerate trash to boil water and produce electricity via steam. These plants treat 200 million tons of municipal waste and produce 130 terawatts hours of electricity. Pike Research says that advanced thermal treatment technologies like plasma arc gasification and biological options—composting and anaerobic digestion—are also emerging.

RE: Global waste-to-energy systems about to ramp
This stuff is great to know, BUT I feel waste management needs to be DECENTRALIZED. Take a peek at what a small waste-to-energy company in Kerala, India is doing. I definitely gotta get my hands on one of their systems and try it out in East Africa. This is what the masses truly need.

WTE has plenty of potential but the likes of the Sierra Club are out to shut them down as big polluters. They feel the reduction in landfill waste and hazardous run-off is not worth the particulate matter and toxic chemicals coming out the smokestacks.

Let's hope they don't win this battle as technology like WTE is beneficial to the economy, provides a valuable and continuous energy source, can be run in a clean-burn mode with post-combustion scrubbers, AND diverts an enormous volume of waste from landfills and our precious watersheds.

It's another fossil fuel alright, but at least it does reduce the overall amount of garbage whose constant increase is still a very large problem.

RE: Global waste-to-energy systems about to ramp
I think that on a large scale, the incinerator or the digester landfills (landfill
gas extraction) make sense if the intent is to do it fast and meet a large
demand for energy, but... I think that gasification combined with plasma
arc gasification is the best approach as far as true efficiency is
concerned.

But, if going for a large scale approach I also think that gasification makes
the most sense. For straight, unsorted MSW a fluidized bed reactor
makes the most sense, but if capital is available for investment in proper
sorting technology then it makes sense to separate the MSW by
feedstock.

By shredding the material down to small sizes and running them under
magnets its easy enough to extract the metals. By steaming it (with waste
steam from the end process) its easy enough to break down the biological
material and separate it from the rest of whats there. In the end its still a
clustered mess, but theres a lot of plastic and other recyclable materials...
when you get the mess of whats left, gasification would allow for syngas to
be extracted which can then be sold as a substitute for natural gas or
converted into transport fuels. It also allows for the dust ash and other
small particulates to be easily filtered out and restored back into the landfill
(taking up much less space and allowing for better, longer lasting
environmental protection against leeching, etc.
The solid materials that are left can then be fed into plasma arc gasifiers
to really break down and separate the non-magnetic metals, rare earth
elements, etc and later sorted again for recycling... as well as allow for the
extraction of more energy.

All of this requires a large initial capital investment and a fairly complex
infrastructure but one that ensures society's waste is ... really no longer
waste, and environmental protection vs just straight incinerators. With
the recycling and the energy extraction, even the large initial investment
will completely pay itself off and be profitable, as well... be environmentally
friendly.

@ ercillor... it also reduces the amount of fossil fuels and other materials
that need to be mined because its using materials that already have been.
