Launched in 2017, the Water2REturn project will aim to demonstrate the technological and economic viability of recovering and recycling nutrients from slaughterhouse residues, transforming them in to high value products with a wide range of agricultural applications.
In an increasingly robust EU circular economy, nutrients and bio-stimulants coming from livestock represent a significant added value; W2R is an initiative which aims to promote the use of nitrate and phosphate compounds recovered from the livestock value chain as organic fertiliser. In addition, an innovative fermentative process involving the hydrolysation of the sludge will allow the production of biostimultants. This process is complemented by proven technologies such as biological aeration systems, membrane technologies, anaerobic processes for bio-methane production and algal technologies, all of which are combined in an integrated monitoring control tool that will improve the quality of data on nutrient flows. The project promotes synergies between food production and sustainable agriculture, and proposes innovative business models which will open up new market opportunities for European industries and Small Medium Enterprises (SMEs). Using the experience of research centres, universities and private sector stakeholders, the coalition will help provide European society with a concrete solution to reduce livestock sector waste, in particular at slaughterhouse level.
