Digestate/Fertilizer Production Consulting

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.

Our Services

Complete Digestate & Fertilizer Solutions

We offer a full range of services to support your fertilizer innovation journey:

Digestate Supernatant Treatment

We remove colloids and separate ammonia (NH₃) efficiently while recovering key nutrients like nitrogen, phosphorus, and potassium.

Nutrient Recovery & Concentration

We design methods to extract nutrients from digestate and concentrate them into liquid or crystalline fertilizer forms that meet agricultural market standards.

Liquid & Dry Fertilizer Development

From liquid foliar formulations to granular dry fertilizers, we transform raw digestate into commercially viable, standardized products — tested and proven in the field.

Custom Sample Production

Our lab produces small-scale samples for your internal trials, investor demos, or certification testing. We provide full nutrient analysis and stability reports.

Plant Design & Cost Estimation

If you plan to scale production, our engineers design customized systems for nutrient separation, evaporation, drying, and granulation.

Independent Consultation

We are completely independent — no hidden sales motives, no equipment partnerships. Our goal is to empower you with data, technology, and the best available options.
