Poultry slaughtering and post-processing activities generate different kinds of highly perishable organic wastes and by-products. Poultry carcass yields are typically about 70–75% of the live bird weight, the rest is accepted as inedible waste. Depending on the efficiency of the processing methods birds’ blood, feather, head, feet, offal and inedible viscera, and in some cases, treated solids make up the slaughterhouse solids in the poultry industry. The management of nutritive organic waste should aim to produce value-added by-products such as pet animal or aquaculture feed components, energy through thermochemical or biochemical processes, and agricultural fertilizer. Conventional rendering at specified temperatures and pressures are widespread processing and well-established methods to produce sellable products in the form of protein-rich meals such as poultry powder, feather powder, and fat. The utilization of raw or processed poultry by-products for animal feed is become strictly banned in both national and international scales for the poultry industry. There has been increasing stress to find alternative areas demanding nutrient-rich solid by-products. The objective of this study is to review several studies with a special focus on poultry abattoir-related activities to draw attention to proper management practices from the environmental point of view. The review shows that best management of the process, high-quality wastes need further innovative and effective processing methods to find possible feed additive either for fish or other animal meal, as well as alternative waste treatment process that provides an opportunity for energy recovery and high-quality bio-nutrient source to be used for crop production.

家禽的屠宰和后处理活动会产生各种易腐烂的有机废物和副产品。家禽car体的产量通常约为活禽重量的70-75％，其余被视为不可食用的废物。取决于加工方法的效率，禽类的血液，羽毛，头，脚，内脏和不可食的内脏，在某些情况下，经处理的固体构成了家禽业中的屠宰场固体。营养性有机废物的管理应旨在产生增值副产品，例如宠物或水产养殖饲料成分，通过热化学或生化过程产生的能量以及农业肥料。在指定的温度和压力下进行常规提炼是广泛的加工和成熟的方法，以生产富含蛋白质的粗粉形式的可销售产品，例如家禽粉，羽毛粉和脂肪。在国家和国际范围内，对于家禽业，已严格禁止将生的或加工的家禽副产品用于动物饲料。寻找替代区域要求营养丰富的固体副产物的压力越来越大。这项研究的目的是回顾一些特别关注家禽屠宰场相关活动的研究，以从环境的角度提请人们注意适当的管理实践。审查表明，该流程的最佳管理，
