In recent years, increasing demand for poultry consumption is leading to an oversupply of byproducts such as feathers, skin, and organs. In 2010, Chicken Farmers of Canada processed about 2.34 billion pounds of chicken. In Canada, approximately 22 million spent laying hens are also produced yearly. Amount of usable meat barely covers the cost of handling of spent hens. In addition, more than 160 million pounds of feathers are produced in Canada each year. Proposed project targets to harvest lipids and proteins from these poultry byproducts and utilize them for the preparation of bionanocomposites for food and non-food packaging applications. Poultry byproducts are rich sources of lipids and proteins. Lipid extraction will be carried out by two different green methodologies, microwave extraction, and supercritical carbon dioxide extraction. The residue, left after lipid extraction, will be subjected to extract proteins using salt/solvent extractions. The extracted and purified lipids will be used to prepare bionanocomposites, adding food grade antimicrobial agents, nano-POSS and/or nanoclays, for food packaging applications. The extracted proteins will be used to prepare bionanocomposites for non-food packaging applications. The evaluations of biomaterials in terms of moisture resistance, thermal, mechanical, and other physical properties as well as biodegradability will be carried out to optimize conditions for best packaging materials. This project will open new opportunities by developing products from a potential waste stream to replace the use of traditional, fossil fuel derived, food and non-food packaging. These bionanomaterials will reduce our dependency on fossil fuels, reduce greenhouse gas emissions, and facilitate transition to a biobased economy. The benefits and outcomes of the proposed project are highly significant to the Canadian agriculture, poultry, food, and plastic industries. The project would result in the development and training of highly qualified personnel for the future of Canadian Advanced Technology and would keep Canada in the forefront of advanced materials production technologies from waste streams.

近年来，对家禽消费的需求不断增加，导致羽毛、皮肤和器官等副产品供过于求。2010年，加拿大养鸡场加工了约23.4亿磅鸡肉。在加拿大，每年也生产大约2200万只消耗的蛋鸡。可用肉的数量几乎不足以支付处理废母鸡的费用。此外，加拿大每年生产超过1.6亿磅羽毛。拟议的项目目标是从这些家禽副产品中收获脂质和蛋白质，并将其用于制备食品和非食品包装应用的生物纳米复合材料。家禽副产品是脂质和蛋白质的丰富来源。将通过两种不同的绿色方法（微波提取和超临界二氧化碳提取）进行脂质提取。脂质提取后留下的残留物将使用盐/溶剂提取进行蛋白质提取。提取和纯化的脂质将用于制备生物纳米复合材料，添加食品级抗菌剂，纳米POSS和/或纳米粘土，用于食品包装应用。提取的蛋白质将用于制备非食品包装应用的生物纳米复合材料。将对生物材料的防潮性、热性能、机械性能和其他物理性能以及生物降解性进行评估，以优化最佳包装材料的条件。该项目将通过从潜在的废物流中开发产品来取代传统的化石燃料衍生的食品和非食品包装，从而创造新的机会。这些生物纳米材料将减少我们对化石燃料的依赖，减少温室气体排放，并促进向生物基经济的过渡。拟议项目的利益和成果对加拿大农业、家禽、食品和塑料行业具有重要意义。该项目将为加拿大先进技术的未来发展和培训高素质的人员，并将使加拿大在利用废物流生产先进材料的技术方面保持领先地位。
