Kaumera is a new bio-based resource which is extracted from aerobic granular sludge originated from the Nereda wastewater treatment process. This sustainable biopolymer is a valuable resource and a viable alternative to a variety of oil-based materials. The first large-scale Kaumera production unit has now been officially opened in Zutphen, with the second production unit in Epe online.
Kaumera offers a wide variety of applications, making it a versatile, environmentally and economically beneficial product for use in agriculture, the building sector, and the textile and paper industries. One of its core features is its ability to both absorb or repel water, offering various opportunities:
The introduction of Kaumera offers a huge step forward for resource recovery and the circular water economy. Using Kaumera as a sustainable biopolymer decreases the amount of fossil resources and first-generation biomass required. In addition, Kaumera production decreases energy use and greenhouse gas emissions in the wastewater treatment process. Nereda technology is used worldwide in wastewater treatment and each Nereda installation has the potential to incorporate a Kaumera extraction unit.
