Waste-to-Energy: Is It a Waste?

Here’s a video depicting the enormous problem that the Lebanese have with the disposal of their municipal solid waste (MSW).  Insofar as it’s part of the venerable “Story of Stuff” project, its central message is that our society simply consumes

Making the Case for Waste-to-Energy

Here’s a gruesome reminder of the need for waste-to-energy technology.  Sometimes the feasibility of plants that extract the chemical energy in municipal solid waste is hard to establish, in cases where the MSW itself isn’t causing problems associated with land

Waste-Tire To Energy

If you wanted to invest a few seconds, you could probably count the tires in the pic on the left.  I don’t think you’d be so successful with the aerial shot below, however.  When I came across this latter photograph

Waste To Energy

Here’s a discussion on that speaks to waste-to-energy (WTE) plants, and why they are not ubiquitous.  In addition to the NIMBY principle, which is severe, the real gating factor here is the presence or absence of regulations as to

From Guest Blogger Brooke Chaplan: Green Waste Technology – Three Alternatives to Messy Landfills

As growing populations result in the inevitable larger, messier landfills, more aggressive and viable solutions are being developed and implemented through three major channels: organic recycling, technology, and other creative forms of recycling at every level. While admittedly not totally

Biomass Has Its Pros and Cons

It’s hard to over-estimate the importance of biomass as a component to a sustainable mix of renewable energy resources—largely for its capacity to convert streams of waste, many of which are toxic, into useful chemical or electrical energy. That’s the

From 2GreenEnergy Intern Fabio Porcu:  Gasification 

Gasification is a thermochemical process which allows the conversion of materials that are rich in carbon, such as coal, petroleum, or biomass, into carbon monoxide, hydrogen and other gaseous compounds. The thermal degradation process requires high temperatures (above 700-800°C) in
