Grassification

A house made from roadside grass fibres, sustainable energy generated from roadside grass, more sustainable and cheaper roadside management. Science fiction or reality? Within the Interreg 2Seas GRASSIFICATION project, research institutes, land managers and industrial partners are examining the possibilities to create economically viable business cases for these and other applications starting from roadside clippings.

Over a period of 3 years, 13 partners from the UK, the Netherlands and Belgium will investigate potential value-chains (from roadside management to novel products) to maximally valorise novel end-products. This research will initiate a new bio-based circular economy, based upon roadside grass clippings.

About the project  

The overall objective of the Grassification project is to apply a multi-dimensional approach to the valorisation of roadside grass clippings in order to optimize it into a viable value-chain for the biobased and circular economy. The project aims to optimize logistics and technical aspects of the grass clippings supply chain and processing, demonstrate its market potential as well as formulate policy and legal recommendations to create a more supportive framework for the recycling of this renewable resource.

These actions will increase the volume of usable material, lower costs, and generate a higher added-value for this so called ‘waste’ streams, which eventually will result in a higher market value of the industry. In this way, the use of roadside grass clippings as a renewable resource for the production of biobased products and hence the circular economy will become more attractive.  

 

Commercial outcomes

For achieving these goals, the Grassification project will have, as main outputs:

  • A novel mowing head aiming at improving the quality and reducing the sand content of the grass clippings
  • Technology tested for decentralized biogas production from the co-digestion of grass clippings with other feedstocks
  • Technology tested for bulk processing of grass into biogas
  • Products made out of grass fibers, such as a picnic set, stepping stones and insulation panels
  • Report on possible applications of the liquid fraction of grass
  • Model developed for joint procurement and performance contracting
  • Techno-economic assessment of the most promising value-chains
  • Supply chain optimization model
  • Policy roadmap

The stakeholders benefitting from these outputs are: road and land managers, SMEs and large entreprises, research institutes and centers, policy makers, and other stakeholders like e.g. the building sector for applications of bio-composite load bearing structures.

Grassification tests new mowing head

Roadside grass clippings are a problem fraction throughout the 2 Seas Programme area due to their high volume, subject to high processing costs. The industrial sector, however, is interested in the possibility of using roadside grass clippings as an alternative resource for the production of energy and bio-materials.

Workshop Grassification: roadside grass as raw material?

On June 18 Grassification organized a demonstration and workshop in Maldegem. Stakeholders came together to compare the clippings of two different cutting heads and to view the refining of the grass by pressing. Various applications were also discussed for the grass fibers and grass juice.

Research project for applications with roadside cuttings

The West Flanders Province participates in the European 'Grassification' project. Within that project, applications are being sought to upgrade roadside grass / roadside grass into raw materials.

Silage verge grass

At the end of October, roadside grass was cut in Harelbeke as part of the Interreg Grassification project. 

That verge cuttings were then ensiled on Inagro for storage and feeding in the anaerobic digester in a few months.

Bulk biogas production from grass

Biogas production from grass is possible, but it suffers from several technical hurdles like litter and sand content, floating layers and fibers getting caught in the digester’s impellers. Therefore, the GRASSIFICATION project is proposing a low-cost, bulk cell for biogas production from roadside grass clippings.

Verge managing experiments in the UK

Currently in the UK, road verges are cut and the grass is left on the verge, in contrast to many other European countries where the grass is cut and collected. This means that large volumes of grass that could possibly be used as a feedstock for energy and products simply goes to waste.

Biorefinery Glas – A Farmer-centric Bioeconomy Approach

Over the last 12 months, Biorefinery Glas, one of Europe’s first small-scale biorefinery demonstration projects, has been working with farmers in Ireland to show how new products and revenue streams can be created using a new farmer-centric bioeconomy approach.

Gramitherm - Insulation panels made out of grass!

Gramitherm is currently the only company - worldwide - to manufacture thermal insulation panels using prairie grass. This involves a patented Swiss technology that was launched in 2006 and that Gramitherm took over in 2014. Gramitherm has excellent performance standards, one of which is to have a negative carbon balance!

Go for Grass

During this year's EU Green Week 2020, which aims to emphasise the contribution biodiversity can make to society and the economy, the GO-GRASS project will shed light on the overlooked potential of grasslands during the online event ‘Go for Grass: exploiting grassland potential in the EU Circular economy’, that will take place on 22 October 2020.

GRASSIFICATION will be presenting some of its results at the 11h30 session!

Stakeholder survey on grass fiber quality requirements

What is the quality of roadside clippings that can be delivered by the organizations responsible for mowing and handling roadside grass? And what is the quality of grass clippings that can be used by companies that refine grass clippings and other plant fibers?

WE NEED YOUR HELP! to establish a viable value chain for grass clippings within the Interreg 2-seas Grassification project.

Deliverable 1.1.1 Support development new type mowing head aimed at minimising dirt content via a co-creation strategy

Within the Grassification project a set of quality criteria for alternate uses of grass biomass will be discussed and will be provided to equipment developers & field-test equipment as developed by machine builders to serve the needs of biomass refinery processes.

Deliverable 1.1.2 Report: Testing & comparison of performance new type of mowing head against existing mowing heads

An important goal within the Grassification project is to use road side cuttings as feedstock for material and energy. To serve that goal the Grassification project started the development of a new type mowing head in cooperation with the different partners to work towards a quality of grass cuttings useful as material and/or energy application.
