The SEEL bio-based filtration platform

Smart Eco Engineering ApS is developing a bio-based drinking-water filtration technology made from food-derived and sustainable materials, offered through the SEEL range of filter jugs, bottles and gym jugs.

We have developed a laboratory-scale MVP with promising results for hardness reduction, chlorine removal and odour improvement, and are now progressing independent validation for PFAS removal, followed by performance, safety and scalability testing.
