LIFE Waste2NeoAlginate: Demonstration of innovative alginate production from granular sludge – a paradigm change in water treatment

LIFE Neo-alginate

Valorising wastewater streams into bio-based products contributes to the EU’s strategic priority of 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 en IJssel demonstrates that innovative Neo-Alginate production is possible from granular sludge, which is produced in waste water 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. Recovery and valorisation of high value Neo-Alginate provides evidence of the relevance of wastewater and process water streams as source for bio-based products.

After successful pilot research, which provided proof of the principle 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.
