Last 30th October 2019, the project partner CENER (National Renewable Energy Centre) published an article on ASEBIO (The Spanish Association of Bio-Companies) on the work currently under implementation within the NextGenRoadFuels project. The article, entitled New bioproducts from sewage sludge, is focused on the relevance of feedstock pre-treating for its use in the hydrothermal liquefaction (HTL) processin order to produce drop-in biofuels for the road transport. Indeed, raw materials such as the organic fraction of urban waste as well sewage sludge have proteins and other Nitrogen-containing compounds. Especially high organic Nitrogen content is detrimental to fuel production and must removed prior to HTL can create problems in an HTL process.

The expertise of CENER is precious, since its role is to perform processes and methodologies based on enzymatic treatment of sewage sludge, through hydrolysis with enzymes at mild conditions. Afterwards, CENER carries out extraction and purification processes. This permits the recovery of amino acids and peptides, which are useful in several contexts (just as in sustainable agriculture, chemical industry, etc.).
