This study identifies the potential greenhouse gas (GHG) reductions, which can be achieved by optimizing the use of residues in the life cycle of palm oil derived biodiesel. This is done through compilation of data on existing and prospective treatment technologies as well as practical experiments on methane potentials from empty fruit bunches. Methane capture from the anaerobic digestion of palm oil mill effluent was found to result in the highest GHG reductions. Among the solid residues, energy extraction from shells was found to constitute the biggest GHG savings per ton of residue, whereas energy extraction from empty fruit bunches was found to be the most significant in the biodiesel production life cycle. All the studied waste treatment technologies performed significantly better than the conventional practices and with dedicated efforts of optimized use in the palm oil industry, the production of palm oil derived biodiesel can be almost carbon neutral.
本研究确定了通过优化棕榈油衍生生物柴油生命周期中残留物的利用来实现的潜在温室气体 (GHG) 减排量。这是通过对现有和预期的处理技术的数据汇编以及对空果串甲烷潜力的实际实验来实现的。从棕榈油厂废水的厌氧消化中捕获甲烷被发现可实现最高的 GHG 减排。在固体残留物中，从壳中提取能量被发现每吨残留物的 GHG 节省量最大，而从空果串中提取能量在生物柴油生产生命周期中则最为重要。所有研究的废物处理技术的表现都明显优于传统做法，并且在棕榈油行业中进行了优化利用的专门努力，棕榈油衍生生物柴油的生产可以几乎达到碳中和。
