Abstract：
The art of using animal hides, an apparent waste from the meat processing industry, goes back to the dawn of humanity and was highly demanded for leather manufacturing. In Ontario (Canada), small- and medium-sized abattoirs process all together approximately 300,000 sheep and 100,000 cattle per year, and for decades, the collected hides and skins have been processed into leather. However, there has been a decline in the price as well as in the demand for animal hides in the last few years, mainly due to increased customer interest in synthetic materials. This has significantly impacted small- and medium-scale abattoirs as they are left with no other option but to landfill these hides, which is not a sustainable approach. This review discusses the alternative approaches available for the management of animal hides, including those also suitable for tannery residues, which can economically and environmentally benefit society. These benefits include the production or generation of energy, compost, yarn, and medicinal goods, among other beneficial uses.
摘要：
使用动物隐藏的艺术，来自肉类加工行业的明显废物，追溯到人类的黎明，对皮革制造的要求很高。在安大略省（加拿大），中小型屠宰场每年处理约30万只绵羊和10万头牛，几十年来，收集的生皮和皮已加工成皮革。然而,在过去的几年中，价格和对动物皮的需求都有所下降，主要是由于客户对合成材料的兴趣增加。这严重影响了中小型屠宰场，因为他们别无选择，只能填埋这些生皮，这不是一种可持续的方法。这篇综述讨论了可用于管理动物皮的替代方法，包括那些也适合制革残留物，这可以在经济上和环境上造福社会。这些好处包括生产或产生能源，堆肥,纱,和药用商品，在其他有益用途中。
