When the process of wood pellets production do not pay attention to the environmental aspects, there will be a negative impact on the environment. Just like the usual plants always have an impact on operations for environment as well as wood pellet plant. The environmental impact was mainly noise pollution and air pollution. Engine or motor of the various units of production in the wood pellets plant is the main cause of the noise pollution. Vibration due to the large variety of equipment operational wood pellet plant also has implications for building damage around the location of the wood pellets plant. To minimize to overcome the problems then use of silencers or the selection of the motor which does not cause disturbing noise and vibration dampening mounting becomes important.
While the problems of air pollution, it is mainly caused by the exhaust gases from the combustion furnace for heating dryers, dust and VOCs (Volatile Organic Compund) of the dryer, dust and cooler from pelletiser. The dust pollution can be more severe if we process of grass type pellet. A number of equipments have been developed to overcome this, as stated in the tables below:
Noise elimination and air pollution needs to be done to the acceptable norms. Considerations such as ease of operation, maintenance and the cost are some important things so that these devices can be applied and reached a level that is safe for the environment. Selection of plant location is quite far from the people settlement are also alternatives to reduce the cost of using the equipments for the elimination of pollutants.
