Digestate Management for Agriculture

Anaergia’s unique AMR™ ammonia recovery technology recovers up to 90% of ammonia nitrogen from anaerobic digestate and can produce a variety of nitrogen digestate fertilizers when combined with acid scrubbing. Our process uses otherwise wasted heat, requires no addition chemicals for carbon dioxide stripping, and features a compact footprint with short hydraulic retention times.

Our PyroSys™ pyrolysis system can be used to convert any type of digestate into Class A-EQ pyrolyzed biosolids. The fully automated process reduces digestate volume, and even eliminates contaminant of emerging concern (CECs), including PFAS and PFOA.

Solutions for each step in the process

Anaergia’s proprietary dewatering technology dewaters digestate in preparation for downstream value extraction or use. Our slow speed and low energy-load equipment is designed to create long duty cycles and be virtually maintenance-free.

Our nutrient recovery solutions recover 90% of the nitrogen, potassium, and phosphorus from high strength waste streams such as filtrate from dewatering.

And extracted water can be treated with Fibreplate™, a next-generation hybrid membrane bioreactor for filtrate and wastewater recycling.
