WTERT-India is latest addition to the Global WTERT Council

The Earth Engineering Center (EEC) at Columbia University, the parent organization of WTERT has signed an MOU with the National Environmental Engineering Research Institute (NEERI) to form WTERT, India. NEERI, headquartered at Nagpur and with five other branches in Chennai, Delhi, Hyderabad, Kolkata and Mumbai is one of the prime research institutes in India. It is a forerunner in research on solid waste management with dedicated researchers. Research conducted by NEERI in 2005 on MSWM in fifty nine Indian cities is one of the most comprehensive studies on this issue. 

It's not waste anymore..

A chilly Chicago played host to the Municipal Solid Waste to Biofuels Summit this week, and the meeting attracted a diverse group of ambitious developers and would-be developers of waste-to-energy/biofuel projects. In the United States the waste-to-energy segment of the green sector remains largely at the demonstration phase. “We’re about a decade away from being project finance ready,” one attendee told G.E.R.

WTE in Cartoons

Toy Story 3 earned three British Association of Film andTelevision Arts (BAFTA) awards due in part to the success of the scene in which the animated characters get trapped in a waste-to-energy facility.
The incinerator scene (duration: 7' 21") can be watched here.

Annie Leonard's unfounded views of Waste-to-Energy expressed in her popular cartoon and book, both titled "Story of Stuff" (Ch: 6) were reviewed by Joanna Schroeder a few months ago. The first of Schroeder's seven part online series on "An In-depth Look at Waste's Role in Energy Development" can be found here.

Waste-to-Energy predictions for 2011

Investment bank Cascadia Capital has published its predictions for sustainable industries in 2011, one of which is that waste-to-energy, helped by rising oil prices, will be more widely adopted. Cascadia specifically mentioned InEnTec, which was recently honored as 2010 Top Innovator by the Wall Street Journal, that uses new technologies to transform industrial, household and even medical waste into electricity and fuel for transport and also mentioned Plasco Energy Group which also uses plasma waste gasification technology. They predict that oil will rise to over $100 per barrel, which will encourage investment in waste-to-energy and also lead to increased use of natural gas making it a more viable energy alternative. As a result, traditional energy companies such as BP, Chevron and Shell will acquire more renewable energy technology companies, including waste-to-energy. Among its other predictions is that Congress will abandon cap and trade in favor of policies that focus on gas, nuclear andrenewable energies.

New SWM plan for New York

New York has finalized a new solid waste management plan - focused on minimising waste up front - for the first time since 1987.
New Yorkers produce more than 14 million tons of waste each year, 20% of which is recycled and the rest is destined for landfills and waste combustors. The plan - Beyond Waste: A Sustainable Materials Management Strategy for New York - sets forth a new approach for the state, shifting from focusing on "end of pipe" waste management to reducing waste from the start. This plan provides a framework to municipalities, businesses and the public  that can help minimize waste, increase the use of materials that can be reused or recycled.

A glimpse at WTERT's Director Nickolas Themelis's work

Turning Waste into Energy

In recent years, Nickolas Themelis has devoted his career to the management of household trash—a fitting occupation for a professor originally from Athens, where the ancient Greeks created the first municipal garbage dump in the Western world near Athens in the sixth century B.C.E.

The engineering professor has overseen a global consortium of experts dedicated to waste management and waste-to-energy research from his desk on the ninth floor of the Seeley W. Mudd building.

Themelis founded the Waste-to-Energy Research and Technology Council (WTERT) in 2003 as part of the Earth Engineering Center, which he directs, at Columbia’s Fu Foundation School of Engineering and Applied Science. WTERT offshoots now exist in Greece, Germany, China, Brazil and Japan, with others planned in France, Britain, India and Mexico. The mission of the consortium is to promote research and innovation in sustainable technologies such as recycling, composting, waste-to-energy and landfill gas capture, as well as to share information among developed and developing countries.

EPA updates WARM

The USEPA has released an updated version of the "Waste Reduction Model" also called WARM.

WARM is a detailed model based on life cycle analysis (LCA) for calculating and comparing the changes in green house gas emissions and energy usage with change in waste handling techniques. It is developed to "help solid waste planners and organizations track and voluntarily report greenhouse gas emissions reductions and energy savings". It is available in two forms, one of which web based calculator is much easier to use than Excel spreadsheet, however in terms of functionality, the Excel spreadsheet which could be used on desktop offers more.

Energy Recovery Council (ERC) releases 2010 Directory of Waste-to-Energy Plants

The Energy Recovery Council today released the ERC 2010 Directory of Waste-to-Energy Plants, which provides current information about the waste-to-energy sector in the United States. In 2010, 86 plants operate in 24 states and have capacity to process more than 97,000 tons of municipal solid waste per day. According to the latest BioCycle estimates, 26 million tons of trash were processed by waste-to-energy facilities in 2008. While this amount is less than the 28 million tons processed in 2006, it reflects reduced waste generation during difficult economic times rather than decreased waste-to-energy capacity.

Techniques and timelines

A city or town can be envisioned as a thermodynamic system with a continuous input of materials and energy, generating work and wastes as output. Most material chains in today's globalized cities are open loops, starting as raw materials and ending up as wastes in landfills. They are not sustainable as the materials move in a single direction resulting in significant depletion of natural resources and causing environmental degradation over time. The creation of natural resources involves energy inputs which are embodied in the wastes that are generated at the end of material loops. Thus, closed material cycles where materials and energy are recycled or recovered hold a key to sustainable world.

Dioxins from WTE and coal-fired plants

QUESTION SENT TO Nickolas Themelis (NJT):

Dear Dr. Themelis,

My name is Nathan Walker and I work as an Environmental Scientist for the Shoshone-Bannock Tribes in SE Idaho. I have recently been doing research regarding waste to energy technologies for the tribes and just finished reading your 2009 Waste Management article entitle Waste-to-Energy: A review of the status and benefits in USA. I enjoyed the paper and found it informative, but was left with a nagging question that I thought you might be able to answer. The majority of the figures used to compare WTE technologies to fossil fuel energy production, especially coal, were not normalized to anything. For example, when you talk about dioxin emissions you attribute 12 g/year to WTE and 60 g/year to coal fired power plants, but fail to take into account how much coal and MSW was burned, or how many kWh were produced. If the mass/year emissions values were presented as mass/year/kWh, or mass/year/ton, or simply as a concentration of flue gas would the MSW emission values continue to hold up? I appreciate your time and look forward to your response.

Regards,
Nathan Walker

RESPONSE BY NJT:
Dear Nathan, there was no intention to castigate coal plants for dioxin emissions because both they and the WTE plants emit very little (by now 6 grams TEQ for WTEs and about 60 g TEG for coal fired power plants). The big dioxin emitter now according to EPA is "backyard barrel burning" (fireplaces, burning grass, etc. etc.,) amounting to about 550 grams TEQ, plus all the fireworks on the 4th of July. Even that 550 grams is insiginifant for a country the size of the U.S.
You cannot compare energy from coal and MSW because coal has about three times the energy of MSW, ton per ton. MSW is a poor fuel and the primary puropse for incineration is to get rid of the MSW with energy generation being a definite plus and much preferable in most urban settings to landfilling.
The U.S. combusts 30 million tons of MSW and about 900 million tons of coal (last time I looked it up some years back) so, ton per ton, MSW emits more dioxins than coal but both levels are insignificant as far as environmental/health effects are concerned. Regards NJT
