Life Cycle Management of Waste
TSMC continuously promotes raw material usage reduction. We have introduced circular economy management methods to independently develop waste recycling technology. TSMC also adopts proactive actions to strengthen vendor auditing effectiveness to ensure legal and proper recycling and treatment of wastes.
In order to sustainably use our resources, TSMC's waste management includes waste reuse, material recycling and energy recovery. We keep increasing the feasibility of waste reuse to realize circular economy.
TSMC completed the amendment of the Company's Articles of Incorporation and added four scopes of business for chemicals in 2017 and successively invested in a number of in-house recycling facilities. With the development and introduction of various recycling technologies, wastes produced from diverse production processes are converted into products which can be reused in-house or sold to other companies. TSMC becomes a participant in the circular economy.
TSMC adopted proactive waste reduction activities. We invested in waste regeneration equipment, and collaborated with suppliers to optimize processes and improve equipment with monthly tracking of execution progress. The weight of outsourced waste disposal per wafer was reduced to 0.40 kilograms from the projected 0.70 kilograms in 2019.
