Abstract

The utilization of poultry byproducts for sustainable and productive production of energy and bioproducts in integrated biorefineries is a promising and beneficial proposition to reduce pollutants in contemporary circumstances. These biorefineries employ chicken byproducts as the raw constituents and utilize these materials to produce high-value biological products via distinctive methods. The implementation of sustainable and eco-friendly biorefineries presents a promising prospect for fostering an environmentally aware economic structure. This study examines the ecological consequences of chicken meat production circular bioeconomy framework. The current research includes development of two distinct scenarios: scenario 1 focuses exclusively on conventional chicken meat production methods and scenario 2 encompasses the production of chicken meat and the economic utilization of chicken feather waste via liquid hydrolysate, as well as the valuation of chicken fat waste to biodiesel and glycerol. As per the results, producing chicken meat according to scenario 2 leads to a 46% reduction in the detrimental impact on human health when compared to scenario 1. Also, the production of chicken meat according to scenario 1 leads to the amount of damage to the ecosystem of 1.03E-5 species per year, while applying scenario 2, this damage is reduced by 43%. Scenario 2 also shows a 34% reduction in resource damage compared to scenario 1 per ton of chicken meat production. The reported reduction percentages shed light on the progress of scenario 2 in reducing its environmental footprint compared to scenario 1, which further highlights the significant advancements in environmental sustainability achieved through the mentioned process.
