In Indonesia, the sugar industry generates substantial quantities of bio-waste annually, presenting both environmental challenges and opportunities for resource recovery. This study investigates the chemical properties of bio-waste from the sugar industry and explores its potential for upcycling. The research focuses on analysing the composition of bio-waste (by-product), including yeast mud and sludge from anaerobic digester, through various chemical analyses such as phase composition (XRD), compound composition (XRF), morphology and element distribution (SEM-EDX). These analyses provide insights into the organic carbon content, nutrient composition, and potential contaminants present in the bio-waste materials. The findings underscore the importance of sustainable waste management practices in the sugar industry, emphasizing the role of bio-waste upcycling in achieving circular economy goals. Recommendations are provided for policy-makers, researchers, and industry stakeholders to promote the adoption of bio-waste valorisation technologies in Indonesia's sugar industry and aim to foster sustainable development and resource efficiency. © Published under licence by IOP Publishing Ltd.
