Abstract

The Ministry of Environment and Forestry added a new criteria, Life Cycle Assessment  (LCA) on PROPER assessment 2021. This assessment aims to identify, calculate the sustainable usage of natural resources, discharge of pollution to environment as well as evaluate and implement possible environmental improvements.
