Material Balance

For a company to promote environmental management through the appropriate evaluation and control of the impact its business has on the environment, it is essential to accurately understand the details of the impact. For this purpose, the Sumitomo Forestry Group collects data on its environmental impact from each plant and business for a range of production processes from energy and raw material input to manufacturing and disposal. The data are compiled to be used to carry out impact reduction measures.
