Abstract Renewable energy can boost the growing population’s need and rapid budgetary development. To reduce fossil fuel consumption is the initial purpose of renewable and sustainable energy, producing valuable bio-based products. The fermenters, using for pretreatment of swine manure, and involvement of swine carcasses are reported to enhance organic loading rate followed by improved biogas yield on household digesters. The compositions such as animal residues, pathogenic microbes, pharmaceutical residues and nutrient compositions including undigested feed are still confused. Therefore, it is mandatory to optimize and stabilize anaerobic practice and digestate filtration purification for consequential fertilizer consumption. The effective biomethane recovery from energy-rich compounds is challenging due to slow degradation procedures. The pretreatment procedure could enhance lipid depolymerization and improve anaerobic fermentation. This article deeply focuses on biodegradation of swine manure. The components of this manure were evaluated and established several approaches to improve biogas production. Furthermore, recycling of co-digestates was discussed in detail as fertilizer consumption including hygienic aspects of manure and pretreatment strategies of biomass residues. Key points • Co-digestion of manure and carcasses enhance bio-methane production. • Removel of ammonia from biogas digester may improve bio-methane gas. • A strong antimicrobial influence has been reported on biogas production. Key words Holistic biomass . Energy . Nutritions . Biogas . Fermentations
Introduction Swine yield is considered a dominant portion of the market available livestock trade. According to the US Department of Agriculture, approximated global swine’s production * Nasir Ali [email protected] 1

surpasses one hundred million tons by 2017 (USDA 2019). China is the biggest market of swine meat that produced 53.4 million tons followed by the European Union, the USA, and Brazil, which produced 23.6 million tons, 11.6 million tons, and 3.7 million tons, respectively, by 2017. These four states produce an estimate of 83% of the global swine food production (USDA 2019). It is reported that there is an expanded heterogeneity of swin
