West Fraser Lumber has several projects in BC where they generate energy from sawmill residuals. Their Fraser Lake and Chetwynd are embarking on two exciting renewable bioenergy projects. The mills are developing North America’s largest biomass power generators. These unique, innovative bioenergy generators – called “ORCs” – are a first for West Fraser. ORC stands for a process called “Organic Rankine Cycle,” a type of energy system that relies on a closed-loop cycle of working liquid to generate electricity. The ORCs will replace Chetwynd and Fraser Lake’s current sawmill residuals burners. The ORC energy systems are the largest applications, worldwide, designed specifically for power generation from biomass. They are an innovative, energy-efficient choice of technology which offers environmental benefits by reducing particulate matter and emissions
