Despite safety improvements, wood pellet plants still face risk of explosions

The investigation into an explosion this week at a wood pellet plant in Entwistle, Alta. has put the spotlight on a facility that is less than a year old and has touted its use of cutting-edge safety technology. Wood pellet plants transform sawdust, and other wood waste products, into pellets that can be burned to produce energy. A lot of wood dust is produced in the process, making the enclosed facilities susceptible to explosions, especially if enough oxygen and heat are added to the environment.
