Processing of nuisance animal waste into agricultural products

A technological solution was developed to process slaughter waste and farm manure and transform them into organic and mineral fertilizers. It has been shown that the formation of an enclosure on a goose farm from nitrogen-binding substances (brown coal, a mixture of brown coal with magnesite, used ash substrate) has a positive effect on reducing nitrogen emissions, even to about 80%. The presented solution is in line with ecological trends and ensures comprehensive management of agri-food waste. It reduces the loss of valuable nutrients from renewable sources, increases the efficiency of fertilizers and reduces the environmental nuisance of poultry farms. Organic-mineral fertilizers made from slaughterhouse waste and poultry manure were as effective as expensive commercial mineral fertilizers. New fertilizers helped to obtain a yield similar to the groups fertilized with mineral fertilizers: 11 t per ha for maize (grain), 0.8 t per ha for mustard (seed), 10 kg per 1 m2 of radish (all), and 18.5 kg per 1 m2 of beet (whole) while reducing production costs thanks to the use of waste materials.

Automated summary

A technological solution has been developed to convert slaughter waste and farm manure into organic and mineral fertilizers. By creating an enclosure with nitrogen-binding substances on a goose farm, nitrogen emissions can be reduced by up to 80%. This solution aligns with ecological trends and allows for comprehensive management of agri-food waste, resulting in increased fertilizer efficiency and reduced environmental impact from poultry farms. The organic-mineral fertilizers made from slaughterhouse waste and poultry manure have been proven to be as effective as expensive commercial mineral fertilizers, and they also help reduce production costs.
