Wright Tech improves Biodryer performance

Richmond Hill, Ontario, Canada, March 18, 2006

Wright Tech has developed a new strategy that can further enhance the performance of its Biodryer technology.

In situations where adequate waste heat is available (landfill gas, process heat, steam from CHP plant, etc), the biological drying process can be mechanically enhanced to increase the throughput capacity (i.e. Tonnes/day) of the Biodryer. Therefore, instead of drying the wet organic waste in 14 days, waste heat augmentation permits the drying process to be completed in less time (5 to 12 days instead).

In addition, this waste heat strategy can also be used to dry the biomass below conventional conditions (15% to 25% MC) for those applications that require a very dry end product (less than 10% MC).

For example, existing and closed landfill sites can either utilize the flared landfill gas or waste heat from genset exhaust to enhance the performance of the Biodryers.

Wright is currently in discussions with several landfill owners, industrial plants and developers who have adequate waste heat available to take advantage of this new strategy.
