Poultry meat production and consumption face several challenges under economic, social and environmental perspectives, and increasing concerns are associated with food loss and waste minimization. One of the main issues is related to the absence of a homogeneous and standardized separate collection of bio-waste at country level, which makes chicken bones, skin and food waste valorization a challenging goal. The present research, implementing the material flow analysis to the Italian poultry sector, aims at measuring poultry-related co-products and by-products, exploring food waste, chicken bones and skin and the current trends in the Italian bio-waste separate collection. Then, it discusses alternative separate collection strategies and sustainable consumption habits. Data have been collected according to a research triangulation approach, whereas system boundaries consider slaughterhouse, distribution and final consumption stage. It emerges that more than 1.50 Mt of live animals have been processed to obtain 0.46 Mt of fresh meat and 0.76 Mt of co-products and by-products, of which more than 0.32 Mt are represented by chicken bones and skin. In addition, more than 0.15 Mt of food waste have been recorded. The research adds an extra step towards the identification of awareness campaigns and separate collection strategies at national level.
从经济、社会和环境角度来看，禽肉生产和消费面临着诸多挑战，并且人们越来越关注将食物损失和浪费降至最低。主要问题之一是在国家层面缺乏统一且标准化的生物废弃物单独收集方式，这使得鸡骨头、鸡皮和食物垃圾的回收利用成为一个具有挑战性的目标。本研究对意大利家禽业进行物质流分析，旨在衡量与家禽相关的副产品和废弃物，探索食物垃圾、鸡骨头和鸡皮以及意大利生物废弃物单独收集的当前趋势。然后，讨论替代的单独收集策略和可持续消费习惯。数据是根据研究三角测量法收集的，而系统边界考虑了屠宰场、分销和最终消费阶段。结果显示，超过150万吨的活体动物被加工，以获得46万吨鲜肉以及76万吨副产品和废弃物，其中超过32万吨是鸡骨头和鸡皮。此外，记录到超过15万吨的食物垃圾。该研究朝着在国家层面确定宣传活动和单独收集策略又迈进了一步。
