Methane fermentation of poultry manure — shortcomings and advantages of the technology: fermentation or co-fermentation?
Overcoming of technological barriers in methane fermentation of substrates including poultry manure derived from poultry-breeding industry is regarded as one of strategic trends in biogas-technology development. The essential limitations and possibilities of such substrates for biogas production is presented here. It should be emphasized, that biogas production based on poultry manure from industrial-scale farms is effective solution of important ecological problem with simultaneous production of green energy and efficient solution of odours emission from the poultry breeding farm. Methane co-fermentation of post-processed bedding premixed with poultry manure solves, at least partly, problem of correct C/N ratio in the substrate mixture.
