Mandarin peel waste, a representative agricultural waste, has been dumped on land and marine environments worldwide, causing significant environmental damage. Thus, a solution is urgently required to reduce direct dumping and convert mandarin peel waste into high value-added products. In this study, to achieve a zero-waste concept, an integrated biorefinery effectively reduced the mass of mandarin peel waste through consecutive processes that included washing, autohydrolysis, enzymatic hydrolysis, and melt compounding. This suggests that integrated biorefinery produced 92.4% of arabinose and arabinooligosaccharide by autohydrolysis and 81.9% of glucose by enzymatic hydrolysis using 5 filter paper unit of cellulase. Overall, the enzymatically hydrolyzed residue replaced 10% of polylactic acid for biocomposite production, which reached approximately 84% of the tensile strength level compared to that of neat polylactic acid. Finally, a concise economic assessment presents the feasibility of an integrated biorefinery by converting value-added products from mandarin peel waste to overcome the environmental and economic problems associated with direct dumping.

柑橘皮废料是一种具有代表性的农业废弃物，已被倾倒在世界各地的陆地和海洋环境中，造成了严重的环境破坏。因此，迫切需要一种解决方案来减少直接倾倒并将橘皮废料转化为高附加值产品。在这项研究中，为了实现零废物概念，综合生物精炼厂通过包括洗涤、自水解、酶水解和熔融复合在内的连续过程有效地减少了陈皮废物的质量。这表明综合生物精炼厂通过使用 5 个滤纸单元的纤维素酶通过自水解产生 92.4% 的阿拉伯糖和阿拉伯寡糖，通过酶水解产生 81.9% 的葡萄糖。总体而言，酶水解残留物取代了 10% 的聚乳酸用于生物复合材料的生产，与纯聚乳酸相比，它达到了约 84% 的拉伸强度水平。最后，一份简明的经济评估展示了综合生物精炼厂的可行性，该厂将柑橘皮废料转化为增值产品，以克服与直接倾倒相关的环境和经济问题。
