Bioenergy production from chicken manure: a review - Springer

Jun 12, 2023 · Adopting waste-to-wealth strategies and circular economy models can help reduce biowaste and add value. For instance, poultry farming is an essential source of protein, and chicken manure can be converted into renewable energy through anaerobic digestion. However, there are a number of restrictions that prevent the utilization of chicken manure in bioenergy production. Here, we review the

Despite Challenges, Research Shows Opportunity To Increase

Apr 10, 2023 · Several factors increase the costs of using manure as a commercial fertilizer replacement. First, manure has a low nutrient value-to-mass ratio. This is partly because of its water content, which can be up to 90 percent of the total weight. The low quantity of nutrients per ton makes manure application and transportation time-intensive and costly.
