Three companies, Bio-Terre Systems Inc., Home Farms Technologies Inc. and Clear-Green Environmental Inc. have different technology and business models but are all attempting to process potential waste into commercially useable by-products. Methane and biogas used to provide electrical energy on a commercial scale, solids that can be composted or used as fuel and thermal energy are typical by products. Each company is developing different approaches to finding commercial solutions. There is no approach that has a clear advantage. The cost of energy, the increasing public pressure for real solutions to environmental issues, and significantly larger-scale livestock operations and processing facilities put integrated solutions in a new light. However, there are issues to be dealt with and business models to develop before these units will be commonplace. Right now the most potential for use is in large processing units such as slaughterhouses. It is hoped that innovation will drive these opportunities and that politicians and industry leaders will begin to deliver the message of these businesses.
