WAI Environmental Solutions waste treatment for the circular economy
- Published 19 December 2022; updated 21 September 2026; estimated reading time 2 minutes. Marked available; listed under Maritime, Aquaculture and fisheries, Circular economy and Industrial production.
- WAI Environmental Solutions treats bio-sludge, organic waste and digestate using belt drying followed by pyrolysis (high-temperature decomposition). The page says outputs include synthesis gas, bio-oil, an “aquatic liquid” and biochar, which it identifies as potential inputs for biogas, energy and agriculture.
- The company presents biochar as a route to recover phosphorus and other nutrients for municipal, agricultural, aquaculture and industrial use. It also describes pyrolysis carbon capture and storage (PyCCS) as a potential negative-emissions application. These resource-recovery and carbon outcomes depend on the feedstock, process and end use; the article gives no quantified lifecycle results.
- The stated benefits include treating waste that might otherwise be landfilled, recovering usable resources, reducing landfill space and environmental hazards, and lowering greenhouse-gas emissions. No measured emissions reductions are reported.
- The article says WAI’s belt-drying and pyrolysis solutions were operating at industrial scale in China and Europe, and that a pilot reactor in Norway was available for customers to test waste streams and analyse outputs. Primary markets are Norway and Europe. WAI was founded in 2017 and has a subsidiary in Weifang, Shandong, China.
- Linked to SDGs 6, 9, 11 and 12.
