The effectiveness of co-additives for improving livestock waste composting (reduction of air pollution and conservation of nutrients) was investigated. Biochar and Flue gas desulphurization gypsum (FGD gypsum) were used to supplement the composting of a mixture of slaughter waste, swine slurry, and sawdust. Different compositions of additives (0% or 5% each, 10% biochar or FGD gypsum) were tested in triplicate on the laboratory scale. In addition, the effects of two different aeration schemes (continuous and intermittent) were also investigated. Ammonia volatilization, physicochemical characteristics, and compost maturity indices were investigated. The results indicated that the use of the co-additive (Biochar and FGD gypsum) during composting of livestock waste led to a reduction of ammonia volatilization by 26-59% and to a 6.7-7.9-fold increase of nitrate accumulation. The total ammonia volatilization of intermittent aeration treatment was lower than that of continuous aeration using co-additives treatment. It was concluded that co-additives (biochar and FGD gypsum) might be utilized in livestock waste composting to reduce ammonia volatilization and improve nutrient conservation.Sustainability 2018, 10, 795 2 of 18 both the aeration rate and the ratio of bulking agent to waste during composting [8,9]. Among the potential odor compounds, ammonia (NH 3 ) is a major component that causes odors nuisance and toxicity to humans and plants [10]. Nitrogen losses that occurred during composting resulted in the emission of ammonia (NH 3 ) gas (ammonia volatilization) accounted for 24-33% of the initial N in household waste [11], 46.8-77.4% of the initial N of a mixture of straw and manure [12], 62% of the initial N was during composting of poultry layer manure [13], and 24-64% of the nitrogen was in organic waste [14]. The volatilization of ammonia deteriorating both human health and the environment would reduce the fertilizer value of the organic waste. Barrington et al. [15] reported that carbon availability, bulking agent, particle size, moisture content, and aeration regime are the factors that determine whether composting results in N volatilization as odor or N immobilization into organic components. The odor emission rate was correlated with both the aeration rate and the ratio of bulking agent to waste when composting [8].The utilization of chemical and biological additives to mitigate ammonia volatilization and nitrogen loss during the composting process has been extensively studied. These additives have included wood fly ash, lime, phosphor-gypsum, polyethylene glycol, jaggery [16], zeolite [17], bentonite [18], superphosphate [19], and microbial inoculants [20]. Among these additives, biochar was popular to be amended in the composting mixture. Biochar is a carbon rich material produced by the thermal decomposition of biomass, was effective for reducing volatilization of ammonia during the composting of a mixture of sewage sludge and wood chips [21]. The faster decomposition process in the bio-oxidative phase...

“…The results are corroborate with the earlier reports of Tiquia et al [30] and Huang et al [31] who observed similar results in spent litter swine manure and saw dust. On the other hand Bharathy et al [32] recorded significantly (P<0.05) lower total nitrogen content in the finished product of compost of broiler slaughter waste.

Present work was carried out in the Department of LPM, FVSc and AH (SKUAST- Kashmir) to assess the feasibility and compost maturity in terms of temperature and bio-mineral (Nitrogen, Phosphorus and Potassium) changes due to composting of poultry waste under the temperate agro-climatic conditions of Kashmir Valley. Poultry waste in the form of poultry carcass (including feathers) and litter manure was used for this study. Four treatment groups with four replicates each were formulated as: G1: Poultry carcass; litter manure, G2: Poultry carcass; litter manure; Paddy straw, G3: Poultry carcass; litter manure; effective microbes (Lactobacillus plantarum, Lactobacillus casei, Saccharomyces cerevisiae and Rhodopseudomonas palustris) and G4: Poultry carcass; litter manure; Paddy straw; effective microbes. During the primary stage of composting the group G4 had attained a significantly (P<0.05) highest peak temperature (0C) of 59.0±5.04 and 59.50±5.04 respectively during winter and summer seasons. Significantly (P<0.05) highest nitrogen content of 24.7 g/Kg was observed in group G4 at the end of secondary stage during summer season. The phosphorus content in end product of composting was significantly (P<0.05) highest (1.0 g/Kg) in group G4 during summer season. Similarly significantly (P<0.05) highest K content of 10.23 g/Kg was observed in group G4 during summer season. It was concluded that the addition of paddy straw and effective microbes assistant the composting process and yield better bio-mineral values and higher temperature gain.

“…Hence, by following an integrated biorefinery approach, the byproducts of the slaughterhouse can be utilized appropriately, not only to reduce pollution (contamination) but also to create job opportunities [2]. Slaughterhouse by-products are taken to be secondary products obtained during the slaughtering and processing of livestock to get meat and by-products exist in liquid, solid, and semi-liquid forms [3,4].…”

A Comprehensive Review on Utilization of Slaughterhouse By-Product: Current Status and Prospect

et al. 2022

View full text Add to dashboard Cite

The meat processing industry produces a huge quantity of by-products, approximately 150 million tonnes per year. The live weight of the animals is distinguished as edible, inedible, and discardable by-products, with the discardable parts equating to 66%, 52%, and 80% of the overall live weight of cattle, lamb, and pigs, respectively. Only a small percentage of those by-products are nowadays exploited for the production of high added value products such as animal feed, glue, fertilizers, etc., whereas the main management method is direct disposal to landfills. As such, the current disposal methodologies of these by-products are problematic, contributing to environmental contamination, soil degradation, air pollution, and possible health problems. Nevertheless, these by-products are rich in collagen, keratin, and minerals, being thus promising sources of high-value materials such as bioenergy, biochemical and other biomaterials that could be exploited in various industrial applications. In this paper, the possible utilization of slaughterhouse by-products for the production of various high added value materials is discussed. In this context, the various processes presented provide solutions to more sustainable management of the slaughterhouse industry, contributing to the reduction of environmental degradation via soil and water pollution, the avoidance of space depletion due to landfills, and the development of a green economy.
