Oyster Shell Biomaterial Plant

Background and Goals

1. To follow the national policy for implementing circular economy and solve the environmental issue caused by oyster shells, TSC has invested NT$ 170 million to establish a biomaterial plant for oyster shell recycling and reuse.

2. The goal of this project to set a benchmark for circular economy in Taiwan.



Progress

1. The Oyster Shell Biomaterial Plant is located in Yongkang District, Tainan. After its completion on June 30, 2020, the Plant has obtained mandatory licenses for operation, including factory registration, waste reuse organization certificate, and stationary pollution source operating permit. After tunning up equipment and establishing all SOPs for facility operation, the Plant went into mass production in September 2021. It has also passed certifications of ISO 9001 and ISO 45001 and eco-mark has been certified by BS 8001 Circular Economy Certification with the highest level of circularity maturity “Optimizing.”

2. Businesses in the agricultural and industrial sectors will be developed continuously. Additionally, with the collaboration among business, academic, and research sectors, technical feasibility and marketing power can be further enhanced for oyster shell powder.

3. Participate in domestic large-scale exhibitions or events, and promote the value of circular economy to enterprises and the public by recycling the wasted oyster shells.


Future Development

Diversified products of the oyster shell powder, such as antibacterial plastics, filtering material,  3D printing material, artwork material, and cleaning agent will be developed. TSC is planning to work on greenhouse gas emission analysis,  carbon footprint certification will collaborate with its clients to enter the international markets and to further enhance industry technology and resource value.


Benefits

1. Oyster shells will be transformed into valuable resources to substitute Calcium Carbonate (CaCO3) produced from white limestones. It will create a positive cycle for job creation, capital flow, and resource flow in the rural village.

2. The circular economy concept has driven positive effects of biomaterial reuse and led a new direction for industrial strategy. Subsequently, environmental protection actions have also been taken, and waste oyster shells have been turned into resources instead of being dumped. A new supply chain of oyster shell reuse has been formed that further fulfilled TSC’s corporate social responsibility and built a stronger brand image for TSC.

3. The maximum processing volume is 50,000 metric tons of waste oyster shells per year.


Collaboration Opportunity

1. TSC is working with business partners and clients for the development of various products, such as antibacterial plastics, filtering material, biodegradable material, agricultural material, eco-friendly material, 3D printing material, artwork material, and cleaning agent.

2. The Biotechnology Business Division of TSC has planned to provide an environmental education program with which the reuse model and various applications of agricultural material can be demonstrated to the public.
