As the worldwide demand for meat per person is continuously increasing, there a corresponding rise in number of livestock animals, leading to an increase manure. Selecting appropriate treatment technologies manures still complex task and considerable debates over this issue persist. To develop more comprehensive understanding manure framework, review was undertaken assess most utilized management underscore their respective challenges. Anaerobic digestion has become commercial reality treating manures. However, mono-digestion single substrates comes with certain drawbacks associated characteristics. co-digestion, involving utilization multiple feedstocks, holds potential overcome these limitations. Extensive research development have underscored numerous intrinsic benefits co-digestion. These include improved digestibility resulting from synergistic effects co-substrates enhanced process stability. This underscores limitations critically evaluates advantages co-digestion carbon-rich substrates. Additionally, delves into key practices globally, emphasizing significance co-digesting while addressing progress challenges field.
