Lignin-based Water Absorbent Hydrogel for Sustainable Agriculture and Soil Recovery

environmentPilotedTRL 7

Imagine a sponge made from wood waste that you mix into the dirt. It drinks up rain water quickly and holds onto it, letting plants sip slowly during dry spells. Instead of staying in the soil like plastic, it eventually turns into natural compost that feeds the earth.

The business problem

What needed solving

Agriculture faces severe water scarcity and soil degradation, with 70% of fresh water used for irrigation. Existing synthetic hydrogels are expensive and non-biodegradable, leaving a gap for organic, cost-effective soil improvers.

The solution

What was built

A 100% lignin-based water absorbent hydrogel that stores water and nutrients and degrades into humus.

Business applications

Who can put this to work

Commercial Agriculture
enterprise
Target: Large-scale crop farms

If you are a crop farm dealing with erratic rainfall and drought, this project developed a lignin-based hydrogel that reduces watering frequency by up to 40%. It helps plants survive dry periods by storing 10-15 times its weight in water in under 30 minutes.

Horticulture
SME
Target: Plant nurseries and greenhouses

If you are a nursery operator dealing with high fertilizer costs and water waste, this project developed a nutrient-trapping gel that enables controlled release of fertilizers. This reduces agricultural input costs and prevents environmental pollution.

Land Reclamation
mid-size
Target: Soil restoration firms

If you are a restoration company dealing with non-productive or 100% sand soils, this project developed a soil improver that converts these areas into productive land. It mimics humus to increase soil organic matter and reverse desertification.

Frequently asked

Quick answers

How does this affect irrigation costs?

The product can reduce watering frequency by up to 40%, which directly lowers water usage and associated pumping or procurement costs.

Is this product ready for industrial scale-up?

Yes, the project title specifically focuses on 'International Scale-up' and utilizes under-utilized lignin from the Pulp & Paper industry as a raw material.

What is the IP or licensing status?

Based on available project data, the technology is developed by AgroBiogel GmbH, a spin-off from the University of Natural Resources and Life Sciences Vienna.

How does it compare to existing hydrogels in terms of regulation and environment?

Unlike fossil-based hydrogels that are non-biodegradable, this organic hydrogel naturally degrades into humus, making it a compliant alternative for green environmental regulations.

What is the timeline for implementation?

The project period runs from 2022-07-01 to 2025-05-31, indicating the scale-up phase is currently active.

Consortium

Who built it

The project is led by a single SME, AgroBiogel GmbH, which is a university spin-off. With a 100% industry ratio and a focused single-partner structure, the project is streamlined for rapid commercial execution rather than academic research, leveraging a direct link to the Pulp & Paper industry for raw materials.
