Track: Sustainability and Green Systems

Abstract

Along the years, sustainability concept has been increasingly relevant to tackle the problem of fulfilling the growing human needs with limited resources. Aside from it, Circular Economy (CE) has also been recognized as one of the initiatives to achieve sustainability. As the two concepts expand, researches that bridge both concepts and develop assessment tools keep flourishing. In this context, this research aims to suggest a framework integrating Life Cycle Sustainability Assessment (LCSA) and Material Circularity Indicator (MCI) to produce an aggregate index reflecting all aspects of triple bottom lines and circularity. Moreover, this research intends to implement LCSA for circular business. Literature review was done to build the framework by combining a couple existing methods. Following it, a study case was conducted to implement the framework. The study case’s object was Company XYZ in Jakarta, a company leasing silicone containers as a substitute for single use plastic food takeaway packaging. The integrated framework produced single scores for the following aspects: environment (5.231), economy (0), social (0.534), and circularity (0.392). Through normalization and weighting, a final single score ranging from 0 (worst) to 1 (best) was constructed. Using this index, companies can attain easier communication and more straightforward comparison for all triple bottom lines and circularity, making it more convenient to design improvements. All things considered, the framework and index are more suitable for micro scale analysis due to its data intensiveness.
