Turn digestate into dividends

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.
