- Hias How2O’s Hias Process uses naturally occurring bacteria grown in biofilm to remove phosphorus, nitrogen and organic matter from wastewater without heavy chemical treatment. The company describes the process as continuous, scalable and highly compact. About 50% of extracted phosphorus is said to become recyclable and suitable for high-grade fertilizer or other agricultural products because chemicals are not used.
- The article says conventional treatment can be costly and chemical-intensive and that over 80% of global wastewater is released untreated, citing UNESCO/UN sources. It describes wastewater as a significant potential phosphorus resource that conventional chemical treatments can make harder to recover.
- Hias says the process can lower cost and improve treatment effectiveness while contributing to agricultural circularity. An independent feasibility study is cited as finding low capital costs and a small carbon footprint compared with mainstream technologies. At-a-glance figures claim about 30% lower total costs than traditional methods and 50% phosphorus recovery.
- Market context cites forecast global investment growth in wastewater infrastructure of over 20% in coming decades; Norway’s investment needs through 2040 are stated as USD 1.75 billion, with global needs in the trillions (OECD attribution). Hias How2O emerged from Hias IKS, a cooperative of four eastern Norwegian municipalities founded in 1974. It belongs to NCE Heidner Biocluster. SDGs shown: 6, 9, 11, 12 and 14.
