Waste Management


Waste Generation and Recycling

ASEH adopts source reduction measures and prioritizes the use of eco-friendly materials to minimize waste generation and reduce environmental pollution. At the same time, we request all facilities to acquire ISO14001 certificates. In 2021, we generated 82,158 tons of waste and achieved a 100% recycling and processing rate by commissioning qualified local firms to process waste within borders. To increase the recycling rate of waste, we adopted the business model of circular economy with the goal to increase the recycling and reusing of waste, achieving a 84% recycling rate of waste, a 2% increase from the previous year.

Moving Towards a Circular Economy

Issues concerning circular economy have garnered worldwide attention in recent years. The increasing depletion of natural resources has shifted the focus of resource recycling and reuse topics to using natural resources more efficiently. Specialized technologies and economic benefits will be the main factors considered in the application and implementation of circular economy to promote active participation in circular economic activities. ASEH continued to implement circular economy projects, which revolve around five key elements: direct recycling, reuse, off-site regeneration, renewable materials, and supply and leasing. With ASEH at the core, we collaborated with suppliers and business partners in the industry chain to build a circular economy in the semiconductor industry. The circular economy features the following activities: redesign, circular value addition, recycling and recovery, shared economy, circular agriculture, and industrial symbiosis. In practice, ASEH has formed alliances with industry peers and other sectors to examine the life cycle and process of resource usage and subsequently identify areas where resources can be reduced, recycled, and reused to prolong their lifespan and maximize resource efficiency.


ASEH actively rallies the support from our supply chain, industry chain, academic institutions and cross-industry partners to promote a circular economy. A total of 48,893 tons of materials were recycled or reused in 2021. For every US$10,000 invested, we contributed to reducing about 128.55 kg of global waste. In the future, we will continue to implement the 5 key elements of circular economy to assist our facilities around the world in reducing waste and greenhouse gas emissions.
