Life cycle assessment of functional food: Improving sustainability in the biotechnology industry through transparency

Abstract

With the advancement of biotechnology, consumers are demanding more scientifically advanced products as well as being more concerned with the environmental impact of products. A life cycle carbon footprint assessment is an important tool in reaching net-zero carbon production goals. This paper presents the greenhouse gas emissions of functional foods by highlighting TCI Co., Ltd. as a case study. TCI conducted life cycle assessments (LCAs) on two mainstream products that utilize common manufacturing processes to examine their carbon footprint and gain a better understanding of their environmental impact. The main finding shows that while the manufacturing stage accounts for around 20–30% of emissions, the raw material stage accounts for 70–80% for both products. This suggests that TCI needs to work closely with its suppliers to ensure a low emissions supply chain and to achieve its net-zero target. Not only do these LCAs allow TCI to increase the products’ transparency, but they can also be offered as a reference to other businesses producing similar products. Sharing of knowledge and practices in the biotechnology industry benefits the entire ecosystem and improves corporate sustainability.
