Green Lean Six Sigma (GLSS) is an approach based on three different approaches (Lean, Six Sigma, and Green Technology) that enables system integration to be improved. The use of GLSS can identify wasteful activities, environmental impacts, and social impacts in the margarine product packaging process. Identification of wasteful activities in the process of packaging margarine products using Sustainability VSM (Sus-VSM). Measurement of resource use to identify environmental impacts on the packaging process uses Life Cycle Assessment (LCA). In achieving social sustainability, it is necessary to use Social LCA (SO-LCA) quantitatively.

Activities that experience waste in the process of packaging margarine products include seven types of waste with the most critical type of waste being Waiting with the largest Total Project Priority value of 720. One of the environmental impacts resulting from the process of packaging margarine products using LCA comes from packaging components. with contributions of 20.7 kPt and cardboard components having the largest contribution, namely 1.6x104 Pt. Assessing social aspects using SO-LCA, only 2 out of 5 social aspects measured met the criteria.
