Stop losing money on reject water. Start recovering value from every cubic meter.
Biogas production leaves you with energy—and a wastewater challenge. The nutrient-rich reject water from digestate is costly to spread, store, move, or treat. NPHarvest changes the equation by letting you recover valuable nutrients on-site, cutting costs while unlocking a potential new revenue stream.
Our system recovers up to 90% of nitrogen and phosphorus from liquid digestate without the need for energy-intensive heating, pressurization, or extensive chemicals. It’s designed to tolerate total suspended solids up to 3 % content and integrates easily into existing flows.
Why biogas operators choose NPHarvest:
Reduced liquid digestate handling costs
Easier compliance with environmental permits and regulations
Recover ammonium salts and phosphorous in pure, resalable form
Lower emissions on scope 1 (N₂O) and scope 2 (CO₂e)
Zero disruption to existing infrastructure and operations
Turn your digestate into more than a leftover – make it a business asset.
