Waste-to-Energy

One of our proposed approaches differs from other known techniques in at least two main features: (1) application of the newly-developed 2nd generation ICP/RF plasma torches with almost unlimited lifetime and (2) the use of oxygen and optionally water steam or carbon dioxide as a gasification medium. This approach becomes feasible because a new generation of high power plasma torches has been developed by our strategic partner Applied Plasma Technologies. These torches can use different plasma gases, including oxygen. Elimination of nitrogen as a ballast dramatically reduces power consumption and hardware dimensions, increases calorific value of synthesis gas, and avoids the formation of nitrogen oxides. Fig.1. shows a pilot module scheme.

Our technology advantages are:

  • Multi-feedstock operation, including MSW + coal gasification, scrap tires pyrolysis
  • CO2 sequestration - MSW or coal gasification in CO2 plasma
  • High efficient plasma generation by hybrid (DC + pulsed IC) torches with long lifetime
  • Possible integration into coal fired utility plants
  • Low maintenance and operating costs
  • Possible increase in electricity output by 2+ MW per ton
  • Further upgrade to near-zero toxicity operation and higher heat recovery degree
  • Proven by 5 years of commercial application and patented technical solutions due to teaming with our partners
  • Portable design
  • Short lead time
  • Worldwide maintenance
  • Permanent technology improvements
We are currently working on a 25 tones per day feedstock capacity pilot module with the main features as follows:
  • Output ~1.9 MW of electricity based on 11 MJ/kg lower heating value (45 MW*h per day)
  • 1.1 MW of thermal energy for district heating (steam and hot water) and 1,800 kg/h fresh water for air based process
  • Multi-feedstock operation – MSW, coal, scrap tires
  • Variable operation modes – from Pyrolysis to Gasification and gasification environment – air, oxygen, water steam, CO2
  • Footprint - 536 m2 (5,360 sq. ft.), including power generation module
  • Lead time - from 12 to 14 months
