Industrial waste

Industrial waste originates from manufacturing operations and is classified according to the regulating authorities in each operating region. It primarily includes chemicals used in manufacturing processes.

TI works to reduce or recycle waste from manufacturing operations. We start by reducing our use of chemicals or disposables. We also recapture and recycle materials, such as valuable pump oils. In some cases, we use high-pressure water instead of chemicals in some cleanup applications. Elsewhere, we replace chemicals with environmentally benign substitutes when possible.

TI can reuse materials and resources in several different ways, and we have even implemented methods to recover metals from solids, liquids and sludge. Some items, including certain solvents, are burned in boilers or industrial furnaces for energy recovery.

We also sell some of our used process chemicals for reuse in other industries. By segregating and repurposing waste chemicals, we reduce the amount of chemicals that need to be disposed and produced for other industries.

In addition, we recycle water used in our fabrication processes by feeding it to utility plant cooling towers for heating and cooling purposes.
