Аннотация:Abstract Life cycle assessments regarding the recycling of food waste through industrial anaerobic processes, pyrolysis, and integrated waste treatment systems have been extensively reported. Among these processes, carbonization emerges as a technique to convert moist food waste into biochar, primarily for soil remediation application. In this study, a life cycle assessment (LCA) was used to evaluate the environmental performance of biochar production through carbonization from food waste in Bekasi, Indonesia. A life cycle impact assessment (LCIA) showed that this process would absorb 6,852 kg of CO 2 eq per t of biochar produced, contributing to decarbonization, and reducing global warming potential. In the sphere of CO 2 emissions associated with biochar production CO 2 eq from syngas and wood fires were identified as the major contributors. However, the presence of methane recovery from the use of food waste classifies the impact of the biochar production process as offsetting. On the other hand, terrestrial ecotoxicity and human non-carcinogenic toxicity are the most dominant effects, with values of 745.1 kg 1,4-DCB and 680.7 kg 1,4-DCB. The impact of this process on terrestrial ecotoxicity is related to wood combustion and the presence of P 2 O 5 and K 2 O in the final product. Non-carcinogenic toxic effects in humans are due to the zinc content in biochar products. Treating food waste with a carbonation approach has shown environmental benefits for climate change mitigation, in addition to economic benefits in the form of marketable biochar.
