GWPT is dedicated to creating advanced, innovative and cost effective technologies that resolve the universal need for carbon-neutral energy production.

Our patented products convert to salable energy:

.  wood chips 

.  yard waste

.  agricultural waste

.  animal litter

8.0 L modified Origin Engine coupled with 50 kW  generator and heat recovery assemblies.  
BEAR primary reactor is  in background. See below.


GWPT’s strategic clean-tech product, the BEAR System (Bio-Energy Access and Recovery System) is a compact biomass-to-energy converter, utilizing wet or dry wood waste and other lignocellulosic biomass as feedstock in a proprietary cogeneration process. 

  • The system processes 1.5 tonnes of seasoned or unseasoned feedstock per day to generate continuous 50 kW of electricity per hour and up to 85 kW of heat power.
  • The system applies a thermochemical reduction science with optimized and scaled down equipment to create a cost effective, easily operated and monitored micro power plant.
  • Your waste and resources are now available to your advantage!

Benefits of the BEAR System :

  • Helps solve our waste problems
  • Fully proven technology exceeding environmental standards
  • Simple, continuous, and automated co-generation
  • Fully warrantied
  • Creates local employment
  • Min. 140 tonnes of CO2eq mitigated per year per operating BEAR 1500-50 unit.
  • The system design is scaled to a standard 6.1 m (20 ft) long container.
  • Designed to be quiet (<60dB at 3 m) and to provide prime power or standby power together with heating and/or cooling.
  • Easily scaled up to a 500 kWe output by adding additional BEAR generator cells.
  • The return of the ash and the CO2 from the BEAR process to the forest closes the loop for both nutrient requirements and sustainable development.
  • Financial solutions for purchasing or leasing equipment is available.



Using the BEAR system means getting involved with a forestry stewardship and management program that advantageously protects your local forests and ecosystems in terms of:

  • Better controlling the establishment, growth, composition, health, and quality of forests to meet diverse needs and values
  • Increasing total biomass output per acre through the above silviculture practices,
  • Integrating with advanced forestry and urban forestry services and forest fire safety management protocols,
  • Offering additional ecological, educational, and scientific opportunities for your community

The BEAR Natural State Reduction System, is a patented hybrid waste gasification, recycling and energy producing system developed by GWPT. The technology can accept seasoned or unseasoned forestry wood waste, wood and many types of biomass at the source with a unique pre-drying hopper. The continuously operating process transforms chipped biomass into Hydrogen, Carbon Monoxide and Methane. In this critical stage, the feedstock is heated and simultaneously starved of oxygen to prevent ignition. In the next stage of the process, the producer gas is cooled and purified to ensure that it is suitable for combustion and does not contain pollutants. The last stage of the process is a sophisticated co-generator which uses the resulting syngas to generate both electrical power and useable heat. The fully automated system is operated by a proprietary environmental supervisory control panel with remote monitoring capabilities.
