How it Works

"PEMTM systems provide a revolutionary way of dealing with two very pressing problems faced by today's society: waste treatment and disposal, and clean sources of energy. The Company believes the PEMTM system is superior to competing methods of waste treatment and disposal because of its economic and environmental advantages and its potential to be used across a wide variety of applications, including distributed power production."

A typical PEM™ system includes the following components:

  • PEM™ Process Chamber
  • Waste Feed Subsystem
  • Glass Former Materials Subsystem
  • Glass and Metal Recovery Subassemblies
  • Process Controls and Instrumentation
  • Process Gas Cleaning Subassembly
  • Power Supply and Control Subassembly
  • Power Conversion Subassembly (optional)


(4.22 Minutes) Richland Plasma Gasification

  • InEnTec Environmental's proprietary Plasma Enhanced Melter (PEM™) transforms virtually any type of waste material into valuable commercial products including:
    • ultra clean fuels that can be used to generate electricity
    • a glass-like material that can be used to create items such as blasting grit or building materials and recoverable metals.

The technology is currently being demonstrated in Richland, WA, where the PEM™ can process 25 tons of the community's waste per day. (YouTube; May 29, 2008)

(3.28 Minutes) InEnTec Plasma Gasification Demo (Port Arthur, TX)

  • The technology was recently tested in Port Arthur, Texas by some of the nation's largest chemical companies. (YouTube; June 4, 2008)

  • Glassifies chemical hazardous waste cost effectively.


  • Solid waste to clean, renewable syngas.

Independent Testing

"The PEM™ has undergone extensive environmental emissions testing by a variety of groups. This testing has been performed on commercial scale PEM™ systems (Models G100 and G200) by IET staff or IET customers using “third party” contractors for the sample acquisition and chemical analysis. For testing conducted in the USA, the sampling contractor –AmTest Air Quality -- has extensive sampling experience and uses USEPA sampling protocols. The chemical analyses of the samples are performed by USEPA certified laboratories. For tests conducted by IET customers in Japan and Taiwan, similar testing, sampling, and analysis protocols are used."

In production in Japan, Taiwan and Port Arthur, TX.


"A total of 42 patents related to PEM™ technologies are owned by, licensed by, or have been assigned to, IET. In addition to these issued patents, IET has a number of patent applications pending in the U.S. Patent Office. Corresponding patent applications have been filed in certain key foreign markets. In addition to its patents, an extensive amount of proprietary intellectual property that has been developed is protected by trade secrets. IET continues its development of intellectual property. The initial inventors of much of IET's intellectual property were Dr. Daniel R. Cohn, Charles H. Titus and Jeffrey E. Surma. Mr. Titus, Dr. Cohn and Battelle Memorial Institute (Mr. Surma's employer at the time of invention) have granted an exclusive license allowing IET worldwide rights for development and commercialization of the initial patents. Development of new intellectual property will involve contributions by the initial inventors, as well as new members of IET's technical team. Detailed proprietary engineering designs for commercial systems have been completed."
"In addition to the PEM™ system, IET has licensed patents and patent applications for two additional R & D 100 Award winning monitoring technologies that were developed at MIT by Charles Titus, Daniel Cohn, Jeffrey Surma, David Lamar and Paul Woskov. These technologies can enhance the capability of PEM™ systems and for certain applications. The first is a Continuous Temperature Monitor (1994 R & D 100 Award), which has the ability to take real time temperature measurements to over 10,000o C in smoky, hostile environments. This technology could allow for more accurate monitoring and control of the PEM™ operating conditions, which could allow more efficient and economic processing. The second technology is a Refractory Corrosion Monitor (R & D 100 Award), which is used to monitor the wear of the furnace lining in areas where a visual inspection would be impossible. This technology could allow for greater planning for scheduled maintenance shutdowns and overall operational reliability. Along with the two monitoring technologies, IET has licensed patents from MIT related to the use of plasma hydrogen production technology in systems using PEM™ technology. These systems can enhance PEM™ capability for environmentally attractive electrical power generation."


Company: InEnTec Energy Solutions LLC

"InEnTec (previously Integrated Environmental Technologies, LLC), the premier provider of plasma-based waste processing and clean energy systems, has developed the proprietary Plasma Enhanced Melter ("PEM™") system that transforms virtually any type of waste material into valuable commercial products including: ultra clean fuels that can be used to generate electricity, a glass-like material that can be used to create items such as blasting grit or building materials and recoverable metals. The PEM™ system has been proven effective for a broad variety of waste streams and the Company has sold and installed commercial units that are operational and processing waste.
"InEnTec has assembled a highly qualified management team and preeminent technical group that have led the Company through its research and development and early commercial acceptance stages to become a revenue generating business. InEnTec is expanding its management infrastructure to accommodate forecasted growth. The management team and Management Committee (which acts as a Board of Directors) include successful entrepreneurs who have created several profitable businesses from the ground up, including publicly traded technology companies. These individuals have a proven track record and understand the intricacies of developing and growing a technology-based business from a clever idea into a thriving, commercial entity.
"InEnTec's world-class marketing and technical group includes experts in the areas of waste conversion, energy production, product development, environmental technologies and the marketing and installation of these systems. This group includes sales and marketing professionals, project engineers, environmental technologists and other specialists who have worked in industry at Waste Management, Rollins Environmental, ABB Lummus Global, MIT, Battelle Pacific Northwest National Laboratory ("Battelle PNNL") and General Electric. In addition, InEnTec has an agreement with Battelle Memorial Institute ("BMI"), a world leader in waste glassification technology and an InEnTec shareholder, pursuant to which BMI will act as an important supplier of technical support and potential customer contacts."
