Characterizing the waste generated from different agro-industrial segments enables the strategic management of residues, with the goal of maximizing recovery within the premises of a circular economy. This research aimed to determine the coefficient of waste generated in broiler chick hatcheries as well as to characterize the waste, taking into account the points of culling and the ages of the laying hens. Furthermore, the waste was used in composting with sheep manure (SM) at increasing inclusion rates (0:100, 10:90, 20:80, 30:70, 40:60, and 50:50). On average, 0.16 kg (DM) of hatchery waste is generated per kg of broiler chicks born. At the hatchery, at least 79% of the total disposal occurs at the hatcher stage. This value is impacted by chicken age (P < 0.05), with birds of a late laying age generating waste with higher contents of carbon (C), volatile solids (VS), ether extract (EE), and nitrogen (N). Culling during egg reception and the manual transfer process account for only 1.8% of the total waste generated on average and thus contribute little to the composition of the overall residues. However, the mechanical transfer process may represent up to 19.0% of the total waste generated by hens of an intermediate laying age. According to the average of all the composting stages, the maximum reduction in solids and C from the hatchery waste was reached when the waste accounted for 50% of the windrow composition. Such conditions resulted in organic fertilizer with the highest N content (2.8%), equivalent to 40.0% more than that in the treatment with no added hatchery waste. The compost resulting from 50% hatchery waste inclusion also had the highest humic acid to fulvic acid (HA:FA) ratio and the highest calcium content due to the higher proportion of eggshells. These findings lead to the recommendation for the inclusion of hatchery waste in composting with SM at a 50% rate by mass.

对不同农业产业部门产生的废物进行表征，可以对残留物进行战略管理，其目标是在循环经济前提下最大限度地提高回收率。这项研究旨在确定雏鸡孵化场中产生的废物的系数，并对废物进行表征，同时考虑到淘汰点和蛋鸡的年龄。此外，废物以增加的掺入率（0：100、10：90、20：80、30：70、40：60和50:50）用于绵羊粪肥（SM）的堆肥。每公斤出生的肉鸡平均产生0.16公斤的孵化场废物。在孵化场，总处置量的至少79％发生在孵化场。该值受鸡龄的影响（P <0.05），晚期鸡只产生的废物中含有较高的碳（C），挥发性固体（VS），乙醚提取物（EE）和氮（N）。鸡蛋接受和手动转移过程中的剔除仅占平均产生的总废物的1.8％，因此对总残留物的构成几乎没有贡献。但是，机械转移过程可能占中产蛋鸡总浪费的19.0％。根据所有堆肥阶段的平均值，当孵化场废物占堆肥组成的50％时，可实现固体和碳的最大减少。这样的条件导致了有机肥中氮含量最高（2.8％），比不添加孵化场废物的处理高出40.0％。由于卵壳比例较高，由50％的孵化场垃圾所产生的堆肥还具有最高的腐殖酸与富里酸（HA：FA）比率和最高的钙含量。这些发现导致建议将孵化场废物包括在按质量计50％的SM堆肥中。
