LIFE Neo-alginate

Valorising wastewater streams into bio-based products contributes to the EU’s strategic priority to make a transition towards a circular and bio-based economy through agricultural and industrial symbiosis.

Currently, industrial side streams and wastewater are often not exploited but simply disposed of. A consortium led by Water Authority Rijn and IJssel demonstrates that innovative neo-alginate production is possible from the granular sludge that is produced in wastewater treatment.

Granular sludge contains a high amount of neo-alginate which can serve as a basis for products such as additives for the paper and textile industry. The recovery and valorization of high-value neo-alginate demonstrates that wastewater and process water streams are a potential source for bio-based products.

Successful pilot research has demonstrated that alginate recovery from granular sludge can be realised. A demonstration is essential to validate the production chain. This demonstration in the ChainCraft installation in Amsterdam allows for easy replicability and transferability.
