The Government of the Republic of Indonesia states that the thermal energy for hot-mixed asphalt production shall be supplied by the direct combustion of fossil fuels in the form of diesel oil, natural gas, or fuel gas from coal gasification which may generate GHG emission. Biomasses are able to substitute the fossil fuels through gasification technology. Gasification converts the biomass using limited air into gaseous fuel containing mainly CO and H₂ that are subsequently combusted to produce heat, carbon dioxide, and water. It is obvious that the CO₂ is then absorbed by the plants for photosynthesis, maintaining a balanced closed cycle. This study examines the level of global warming potential of this system for supplying heat based on the openLCA v1.9 software. The analysis used a gate-to-gate approach to evaluate scenarios of shell gasification to produce 1 metric tonne of hot-mixed asphalt. The scope covers raw material supply and transportation, palm kernel shell gasification, and products. The evaluation concludes that gasification could potentially reduce CO₂ emissions. Environmental impact analysis and interpretation of the results using the openLCA database of Traci 2.1 recommend that greater CO₂ emission reduction is possible using palm kernel shell gasification, not only for supplying heat but also for electricity generation to operate all electrical equipments.

棕榈仁壳气化为沥青搅拌站供热的生命周期分析

印度尼西亚共和国政府声明，用于热拌沥青生产的热能应通过直接燃烧化石燃料来提供，这些化石燃料的形式为柴油，天然气或煤气化产生的煤气，可能产生温室气体排放。生物质能够通过气化技术替代化石燃料。气化利用有限的空气将生物质转化为主要包含CO和H _2的气体燃料，这些气体随后燃烧产生热量，二氧化碳和水。显然，CO ₂然后被植物吸收以进行光合作用，维持平衡的封闭周期。这项研究基于openLCA v1.9软件检查了该系统的全球变暖潜能水平。该分析使用了“门到门”方法来评估壳气化的情景，以生产1吨热混沥青。范围涵盖原材料供应和运输，棕榈仁壳气化和产品。评估得出结论，气化可以潜在地减少CO ₂排放。使用Traci 2.1的openLCA数据库进行环境影响分析和结果解释，建议更大的CO ₂ 使用棕榈仁壳气化技术可以减少排放，不仅可以供热，还可以发电以操作所有电气设备。
