Perspectives: Energy Saver

Reduce and Recycle Hazardous Materials

Optimize waste to save energy and disposal costs and cut process inefficiencies

By Ven V. Venkatesan, Energy Columnist

Nearly every plant produces waste that must be disposed without affecting other facilities and the environment. Removing and disposing of these materials can be costly. Excessive waste also is a symptom of process inefficiencies.
