Recycled Fertilizing Materials

Waste Producers

Livestock breeders

Manure and slurry, have been traditionally used in agriculture due to their nutrients content, necessary for crops. However, it hasn’t always been possible to adjust their continuous production to agronomic cycles, impacting negatively over the agricultural and hydric environment. It is completely necessary to manage these surplus products in a suitable and sustainable way.


Villages and cities have wastewater collection networks that converge in the WWTP, which will treat them in successive phases, to return clean water to public waterways and rivers. The organic part contained in water before entering is treated, resulting in sludge. These are rich in organic matter, and when they are suitable for agriculture, become a very interesting nutrient contribution for crops. The management of these materials is regulated by law, and it is mandatory to implement it with a high degree of knowledge and technical competence. Sludge origin will inform about its LER code, which identifies and determines its way of management.


Agri-food industry and in general those ones with high water consumption, must necessarily purify and treat their process waters, it’s when their bio-wastes are produced. These are treated wastes, considered non-dangerous and suitable for agriculture. They are rich in nutrients and organic matter, and their thorough identification is mandatory to evaluate their fertilizing potential, followed by a rigorous fieldwork methodology linked to responsible and effective logistics.

Municipal Solid Waste (MSW)

Cities development has historically led to the increase of waste generation, that must be managed in an appropriated way. The municipal wastes with high organic content, are collected separately and treated in specially designed facilities. The final material, OFMSW, is rich in organic matter and nutrients optimal for agriculture, gardening restoration of degraded areas and public work.
