Environmental Sustainability of Waste Circulation Models for Sugarcane Biorefinery System in Thailand

Sugarcane leaves and trash burning during harvesting, vinasse management, are major challenges of the Thai sugarcane industry. Identification appropriate valorization pathways for both biomass waste streams using biorefinery concept is necessary. This study aims to assess environmental sustainability five CE models, including (1) electricity, (2) biochar, (3) as a soil conditioner, (4) bio-fertilizer, (5) power generation. Life cycle assessment has been conducted ReCiPE midpoint impact method. The results revealed that all utilization scenarios can help reduce impacts compared base case. electricity generation brings about lowest due credits from substitution grid electricity. on climate change, terrestrial acidification, ozone formation by 20–104%, 43–61%, 12–54%. Recycling bio-fertilizer biogas production change 28–29%. There significant improvement avoidance pre-harvesting in sugar industry, which led big potential utilization. Recommendations enhance efficiency discussed. integrated circulation cane vinasses sugar-electricity-ethanol shows advancement bio-circular-green economy (BCG) aspects enhancing
