Turning Municipal Bio-waste into High-Performance Soil Fertilizers for Agriculture

environmentPilotedTRL 8

Imagine taking the food and garden scraps from cities and turning them into a super-charged vitamin boost for tired soil. By mixing a special charcoal made from waste with the liquid leftovers from biogas plants, the project creates a sponge-like material that holds water and nutrients better. It's like giving the earth a probiotic treatment to help crops grow without needing expensive chemical fertilizers.

The business problem

What needed solving

Agricultural soils are losing nutrients and water-holding capacity, while biogas plants struggle with the high cost of disposing of nutrient-rich digestates. Simultaneously, 34% of municipal waste is bio-waste that remains underutilized.

The solution

What was built

A formulated soil amender combining optimized biochar (selected from 36 lab-scale variants) and anaerobic digestion digestates.

Who can put this to work

Waste Management
enterprise
Target: Municipal waste processing plants

If you are a waste processor dealing with the fact that bio-waste makes up 34% of municipal waste — this project developed a way to convert that waste into biochar and digestate mixtures that turn a disposal cost into a sellable soil product.

Renewable Energy
mid-size
Target: Biogas plant operators

If you are a biogas producer dealing with high costs for disposing of nutrient-rich digestates — this project developed a method to combine these effluents with biochar to create a high-value biofertilizer, improving the overall profitability of AD projects.

Agribusiness
any
Target: Commercial farming enterprises

If you are a farm owner dealing with land erosion and nutrient depletion in poor soils — this project developed a soil improver that boosts agricultural yields and increases water retention capacity across different soil types.

Frequently asked

Quick answers

What is the cost or price of the final soil improver?

Based on available project data, specific pricing is not provided, but the project aims to demonstrate economic returns by reducing digestate disposal costs and replacing fossil-fuel-based fertilizers.

Can this be produced at an industrial scale?

Yes, the project aims to demonstrate the product at TRL 8 in field tests across Spain, Greece, and France, indicating a move toward industrial-scale application.

How is the IP or licensing handled for the biochar formulations?

Based on available project data, specific licensing terms are not mentioned, but the project involves 4 industry partners and 2 SMEs ready to take up the results.

Does this comply with EU waste regulations?

The project specifically targets the EU goal to recycle 65% of municipal waste by 2035 and follows European Biochar Certificate (EBC) standards for characterization.

What is the timeline for market availability?

The project runs from June 2023 to July 2027, with field demonstrations (TRL 8) planned as part of its objectives.

Consortium

Who built it

The consortium is strongly geared toward commercialization, with a 44% industry ratio (4 industry partners, including 2 SMEs). The balance between 3 universities and 2 research centers ensures the scientific validation of the 36 biochar types, while the presence of industry partners across 4 countries (DK, EL, ES, FR) suggests a clear path from lab-scale characterization to TRL 8 field deployment.
