Reusable Package—Flexible and Logical Material Choice

Cha Tzu Tang considers sustainability not only just an implementation of recycling, but also an establishment of a long-term strategy based on each enterprise’s need. What is more important is to create an exclusive system for packaging choice within the concept of sustainability.

In 2025, Cha Tzu Tang intends to become one of the representatives of the circular economy in Taiwan by strengthening the sustainability level in every part of its brand; including communities, farms, factories, companies, stores, products. This project consists of 7 subprojects; one of them is reusable packaging, where the enterprises mainly put their efforts in to make the disposable packaging reusable and returnable.

To reach the target, Cha Tzu Tang has launched a campaign in collaboration with REnato Lab to scientifically attain a balance between business demands and environment preservation. In the context of reusable packaging, Cha Tzu Tang took advantage of Analytic Hierarchy Process (AHP) to come up with 4 evaluation standards to help selecting appropriate packaging materials. Regarding the process of AHP, the enterprise first exclude those materials that could potentially be prohibited in the near future by conducting a global investigation into the associated legislations. Second, the enterprise compiled a general list for evaluation that fulfilled the packaging needs of Cha Tzu Tang. After a thorough and discreet evaluation, 4 main evaluation standards were finally determined—material circularity indicator, carbon footprint, recycling rate, and buyback price.

Buyback price : With a study in the price of the associated recycled materials among the market, the price is determined by DOLLAR/KG. Material Circulatory Indicator: According to Ellen MacArthur Foundation, material circulatory indicator comprises factors such as recycling rate, reuse rate, material leakage, etc. Carbon Footprint: The amount of carbon emission resulted from the transporting, sorting and processing the used packages. Recycle Rate: The amount of trash recycled in compared to the trash produced under the supervision of an organization.

Based on the scientific theory, the development department of the enterprise have a clear path to achieve circular economy in 2025 by completing each of the subprojects on schedule.
