BIOFERTILISERS FROM BIOGAS PLANT DIGESTATES. LIFE IN BRIEF CONCLUDES SUCCESSFULLY

Subsequent to three years of work, the Life In Brief (LIFE14 ENV/ES/000427) project has concluded. The project was a joint effort featuring companies from the fertiliser sector, biogas plants, engineering companies, agricultural services companies and the AIDIMME technology centre. The technical processes and agricultural trials were successful, and the project results were presented in Vall d´Uixó on March 15.

Fertiliser production and natural gas have traditionally been mutually-linked two sectors, for example, in the synthesis of ammonia or urea. On the renewable side of the equation, it would seem that renewable natural gas production and biofertiliser production are also going to be closely linked, albeit for very different processes.

Spain has enormous potential for biogas exploitation, mainly in the agro-industrial sector. Our country has the largest pig population in Europe, a very large cattle and poultry population,
and one of Europe’s most powerful agro-food industries, which generates hundreds of thousands of tonnes of waste. The potential for biogas development is enormous.

At the same time, most of the surface area of Spain has problems of aridness and water scarcity, meaning that it cannot allow poor management of organic biowastes, such as manure or sewage sludge, to pollute aquifers. Transforming waste into resources is one of the keys to closing the loop in circular economy systems and one of the main pillars of the Roadmap to a Resource- Efficient Europe. In this respect, the EU affirms that both biowaste and sewage sludge are biodegradable wastes with great potential for conversion into resources through chemical, mineral and nutrient recovery processes.
