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.

Strategies, Targets & Achievements

Strategies
  • Source Reduction
    Promote raw materials usage reduction, require process tool suppliers to review and minimize chemical usage
  • Circular Economy
    Study and develop waste reuse and recycling technology, encourage and support vendors to develop recycling technology
  • Audit & Guidance
    Initiate within Science Park Industry Association to establish "Waste Vendor Assessment Standard" and leverage the power of association members to upgrade the overall quality of waste industry

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...

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.

Key Projects on Waste Reduction

TSMC formed a cross-organization "Waste Management Task Force" to promote raw material source reduction and in-house waste reuse and recycling. We conducted several key projects on waste reduction, encouraged employees to innovate all the time and found ways to improve sustainable performance.

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 0.35kg from the 0.49kg forecast in 2016.
