Transform Waste into Value
From Waste to Worth — Redefining the Future of Fertilizers
At Digestate Fertilizer Consulting, we specialize in transforming digestate — a by-product of anaerobic digestion — into high-value, nutrient-rich fertilizers and soil enhancers.
Our mission is to create a sustainable bridge between waste management and agriculture, helping farmers, biogas operators, and industries recover nutrients, cut costs, and protect the planet.
About Us
Science Meets Sustainability
Digestate Fertilizer Consulting was founded with one goal: to unlock the hidden potential of digestate.
With over 30 years of collective expertise in agronomy, chemistry, microbiology, and process engineering, our team understands the science behind nutrient recovery — and the business behind sustainable fertilizer production.
We’ve invested over $3 million in specialized analytical and pilot-scale production facilities, dedicated entirely to digestate research and testing.
Our laboratories analyze the nutrient composition, contaminants, and process variables that determine how digestate can be upgraded into marketable fertilizer products.
Unlike traditional equipment vendors, we don’t sell machines — we sell knowledge.
Our independence ensures you get honest, unbiased advice, guided only by what’s best for your operation and your long-term return on investment.
How We Work
From Analysis to Application
Every project we take begins with a scientific foundation.
Here’s how we help you achieve results step-by-step:
Digestate Analysis
We perform detailed lab testing to understand nutrient content, pH, ammonia levels, and solid composition.
Process Evaluation
Our experts evaluate your existing setup, feedstock types, and storage or treatment methods.
Custom Treatment Design
Based on data, we design or optimize your process for nutrient recovery, odor reduction, and stability improvement.
Sample Production & Testing
We create small-batch fertilizer samples (liquid or dry) and test them under real field conditions.
Scale-Up & Implementation
Once validated, we help design your plant layout, estimate costs, and support full-scale production setup.
Ongoing Support
From regulatory compliance to product certification — we’re with you at every step.
