Abstract

This study examines the life cycle analysis of the manufacturing of 1 kg of green tea using various disposal techniques, including landfill procedure, incineration, and modification of green tea waste as an adsorbent for heavy metal removal. OpenLCA is used to produce the evaluation. To identify the objectives and scope, inventory analysis, effect, and interpretation, the assessment process corresponds to ISO 14044 of 2006. AGRIBALYSE version 3 is the database used to evaluate the environmental effects. A reference unit called a DALY is used to study the environmental impact. For the LCA of green tea, there were four main effect categories that were taken into consideration: human carcinogenic toxicity, human non-carcinogenic toxicity, global warming (human health), and fine particle creation. The outcome demonstrates that processing 1 kg of green tea waste has an environmental effect that is around 63% greater than incinerating it and roughly 58% higher than dumping it in a landfill. However the ecology is more affected by the adsorption process than by landfill and incineration of green tea waste. Even yet, if the preparation is done in bulk, the process can be improved by altering the adsorption of green tea waste.
