Converting Organic Matters from European urban and natural areas into storable bio-Energy
December 2011 – June 2015
The COMBINE project continues from 2016 with REDIRECT
The COMBINE Project was a pan-European investigation into the feasibility of turning biomass material, particularly that of low nutrient or waste value into fuels. Materials such as soft rush, gorse, bracken, grass and roadside verge material was cut, stored and then solids processed into fuel briquettes and liquids to anaerobic digestion.
COMBINE was funded under EU funding INTERREG IVB.
The Project Objectives
- Producing storable solid fuel with a highly energy-efficient process
- Utilising biomass from extensively used grassland areas and landscape management, which can neither be used in animal feeding nor in conventional energetic conversion technologies
- Increasing the efficiency of biomass supply chains, through the addition of a year-round heat sink in distributed biogas or AD plants and by new harvesting and conditioning techniques.
- Creating new energy supply chains from biomasses in the project regions and beyond
- Securing livelihood for small farmers and disadvantaged persons in retreated areas through the creation of new income sources and regional added values with renewable energy production
- Contributing to reducing the conflict between bio-energy and food production by exploring and utilisation of new raw materials.
COMBINE is based on the IFBB technology. IFBB stands for integrated generation of solid fuel and biogas from biomass and was developed at the University of Kassel in the early 2000s. It was tested on laboratory scale up to the year 2008 and successfully up-scaled (to 1:20) between 2009 and 2012 in the forerunner project PROGRASS.
In COMBINE the technology will be combined with a strategic and participatory regional development approach that will be implemented in four diverse NWE regions to trigger large-scale investments in decentralised bioenergy production. Major strategic innovations allow COMBINE to contribute to the development of an environmental-friendly biofuel production.

The Welsh Partners, and hosted by National Trust Farm; Hafod y Llan, successfully demonstrated a small version of the IFBB process in the mobile unit Blue Conrad. Blue Conrad features a screw press and mash stage, briquetting and anaerobic digestion. It takes in biomass material which has been stored in silage bales to produce a range of outcomes. Many farmers and officials visited the site and enjoyed the demonstration.
The mobile processing unit was based in Wales during November 2013. Demonstrated on National Trust land who are keen to turn soft rush, gorse and bracken crops into viable biomass fuels.
