Inhabitants development and elevated consumption generate a rise within the amount and number of waste. For years, analysis has been in search of methods to recuperate this waste that, beneath the umbrella of the round economic system, present environmental, social and financial advantages to society.

On the agricultural stage, over the last many years there was an intensification and focus of agricultural and livestock exercise in very localized areas, inflicting issues within the administration of the waste generated.

On this sense, a multidisciplinary analysis group from the College of Córdoba led by the researcher from the Chemical Engineering group Mª Ángeles Martín and made up of researchers from that group and with the participation of the researcher Adolfo Peña Acevedo from the Hydrology and Agricultural Hydraulics group, have targeted on discovering options to agricultural waste generated within the province of Córdoba.

The poultry trade within the province generates massive portions of rooster manure, a waste generally known as poultry manure that have to be handled correctly for environmental causes. By including rooster manure to the by-products of two predominant crops within the province equivalent to olive bushes and cereals, the analysis group has managed to generate an natural fertilizer ensuing from the valorization of those wastes by the ‘co-composting’ course of (managed degradation of natural waste by mixing strong natural waste). On this method, a product of excessive agronomic worth is obtained from agricultural waste.

The analysis of the technical feasibility of co-composting rooster manure, alperujo and olive tree pruning stays with cereal straw on the Coto Bajo composting plant in Córdoba concerned monitoring the method when it comes to high quality and stability of the ultimate product, in addition to the odorous affect derived from the remedy, since one of many most important issues of fertilizers from manure is the emission of disagreeable odors.

To keep away from dangerous odor, as a novelty within the research, a fermentative remedy of the combination previous to the co-composting course of was included, which facilitated the decomposition of natural matter and minimized odor emissions.

The mix of each remedies (fermentation and co-composting) has made it attainable to acquire a sanitized, steady and high quality remaining product with the ensuing environmental and financial profit derived from the restoration of waste.
