Northbrook, Illinois & Shanghai, China – October 10, 2013 – PEAT International, Inc., (“PEAT”) a leader in plasma-thermal waste destruction systems, announced the successful commissioning of a Plasma Thermal Destruction and Recovery (“PTDR”) system in Shanghai, China. The 60 kg/hr system – designed for medical waste and oil refinery sludge – was installed for Abada Plasma Technology Holdings, Ltd. – an Asian-based renewable energy project developer.

PEAT’s PTDR “single stage” plasma-thermal process transforms hazardous waste through molecular dissociation at 1,500°C (2,732°F) into recoverable, non-toxic end-products, synthetic gas and heat (sources for energy recovery), metals and a vitrified glass matrix. Emissions are below the most stringent environmental standards used anywhere.

“This is end-stage technology and sets the standard for clean hazardous waste remediation. Only with plasma can you achieve temperatures high enough for waste destruction in a single-staged process,” said Joseph Rosin, PEAT International Chairman. “It’s a 21st century solution that addresses three important needs: significant volume reduction, full pollution control and competitive pricing. We are currently preparing for other projects already under contract.”

PTDR systems are in operation in California, Taiwan and China. Go to http://www.peat.com/chinasystem.html for a video of operations and acceptance test run data.

About PEAT International

PEAT International, Inc., headquartered in Northbrook, Illinois, with offices in China, Taiwan and India, is a waste-to-energy (“WTE”) company with its two proprietary technologies – the Plasma Thermal Destruction and Recovery™ (“PTDR”) technology for the treatment and recycling of industrial, medical and other hazardous waste streams and the Thermal Volume Reduction & Conversion™ (“TVRC”) technology for municipal solid waste. For more information, contact Daniel Ripes, dripes@peat.com, at 847-559-8567 and visit www.peat.com.

PEAT’s solution for municipal solid waste is the Thermal Volume Reduction & Conversion™ (“TVRC”) technology – an innovative system that combines a thermal volume reduction system with its core PTDR plasma-arc plasma gasification system.

Each TVRC system (modular) can process up to 250 tons per day of municipal solid waste (MSW) with no secondary pollution or unusable by-products generated: all feedstock represents a 100% waste diversion, eliminating the need for landfill disposal and/or further processing. It eliminates any future liabilities to the generators resulting from the use of outside collection, treatment and disposal services/facilities that are potentially unscrupulous. Further, a TVRC system generates high volume (over 8 to 1) and weight (over 4 to 1) reductions.

In a TVRC, MSW is first thermally processed in a high temperature reactor/boiler to generate steam. This steam is then processed in a full condensing steam-turbine generator for electricity production.

Any gas generated is processed through a flue gas cleaning system that removes any potentially harmful gases to surpass European emission standards.

Any fly ash generated in the high temperature reactor/boiler is processed is the PTDR plasma-arc plasma gasification & vitrification system. The PTDR converts the ash into an inert, non-leachable vitrified matrix that can be used in a variety of commercial applications including concrete aggregate, insulation, roadbed/fill construction and even in decorative and non-decorative tiles. Independent laboratory tests (i.e. “TCLP”) have proven that the vitrified matrix does not leach, is totally benign and safe for any re-utilization.

Any residual by-products generated in the gas cleaning systems (i.e. baghouse catches, scrubber residue, etc.) is collected and also processed in the PTDR system, thereby creating zero residual waste from the TVRC.

Dioxins are an issue often cited in the marketing literature of many plasma gasification waste-to-energy technology suppliers as an area where plasma gasification may be superior to other thermal waste processing options. Studies have shown the majority of dioxins are formed within the cooler regions of processes via flyash catalyzed processes, involving chlorine and organic compounds (usually called products of incomplete combustion) in so called de-novo synthesis reactions.

It has been demonstrated (see below table) that the higher temperatures from PEAT’s plasma thermal destruction and recovery waste-to-energy process provides for substantial conversion of the organic constituents of the waste and therefore significantly reduces the likelihood of downstream dioxin formation. (There is some credence in the claims that the reducing conditions present in plasma gasification processes could minimize dioxins as the precursor formation reactions usually require excess oxygen).

Dioxins form when all of the following constituents present: carbon, hydrogen, chlorine, and oxygen in appropriate quantities. Once all these elements are present in sufficient quantities, the temperature must also be high enough to promote the formation of such a complex compound, and not so high that the molecules formed become unstable. This temperature zone has been widely estimated to be between 200°C and 450°C. However temperature is not the only mitigating factor as there could be dioxin precursors in the off-sygas/pre-cleaned syngas leaving the plasma gasification reactor thus PEAT’s plasma thermal destruction and recovery waste-to-energy systems provide for rapid quenching of the gas (i.e Venturi quench). This is to avoid the de-novo synthesis temperature window.
