Waste Management

TSMC understands the importance of waste resource management in green manufacturing. In order to sustainably use our resources and properly treat our waste, we continuously reduce generation and reuse on-site waste. Collaborating with our supply chain, TSMC keeps building up world-class green power.

First in the Semiconductor Industry to Adopt Two Waste Resource Regeneration Technologies

First in the Semiconductor Industry to Adopt Two Waste Resource Regeneration Technologies

TSMC was first in the semiconductor industry to adopt two waste resource regeneration technologies. In 2016, TSMC cooperated with vendors to develop and implement in-house copper extraction equipment to produce copper tube 9.7 metric tons from copper sulfate. This system avoids sending 445 metric tons waste copper sulfate out for external treatment, saving NT$2.2 million...

The First in the Industry to Develop and Implement In-House Equipment to Extract Copper from Waste Copper Sulfate

The First in the Industry to Develop and Implement In-House Equipment to Extract Copper from Waste Copper Sulfate

In 2016, TSMC cooperated with vendors to develop and implement in-house copper extraction and waste regeneration technology to reduce the amount of copper sulfate outsourced for treatment. Some 1,942 metric tons of waste copper sulfate intended for outsourcing treatment were regenerated inhouse into 42 metric tons of copper tubes. Based on this successful experience...

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.

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 amount of waste outsourced for processing per 8"e wafer-layer has been reduced to 0.36kg from the 0.59kg forecast in 2017.
