Go grass

Problem statement

GO-GRASS is committed to transform this untapped potential, making it usable, reducing imports of nutrients and dependence on fossil fuels and finding ways to provide the resulting benefits to strengthen rural communities

Executive summary

The GO-GRASS project will develop a set of small-scale bio-based solutions to unlock the overlooked potential of grassland across Europe and create new business opportunities for rural areas

Value chain description

a) In the Swedish demo, Reed Canary Grass (RCG) is shredded and pressed into briquettes – an innovative material for animal bedding which afterwards can easily be used as fertiliser, as well as for biogas or heat production b)The German demo site at Nationalpark Unteres Odertal converts low nutritional quality grass from the wetlands into biochar. By implementing a first complete processing line, the grass is transformed into biochar by pyrolysis or hydrothermal carbonisation (HTC) c) The Dutch demo site develops a process to extract fibres from roadside and nature grass to produce high-quality packaging and paper.d)The demo site in Denmark manages a small green biorefinery for extracting protein from grass. The organic protein concentrate extracted can be fed to pigs and poultry to enrich their diet. Other product streams are a fibrous pulp, that can be used for ruminant feed or biomaterials as well as brown juice that can be used as fertilser.The facility is working on the optimisation of biorefining processes to provide high yields and high purity of the protein product as well as quality co-products in the form of renewable bioenergy and recycled nutrients. For the validation and documentation of the nutritional value of the products in animal feed, trials will be conducted with local farmers. To make alternative grass-based markets more dynamic, increasing consumer awareness through adequate marketing is perceived as an important aspect. Capacity building and alignment efforts need to be strengthened and coordinated at local and higher levels to enable the replication and scale-up of novel grass-based businesses in Europe and beyond.

Market deployment considerations

An increased awareness for sustainable bio-based products is fundamental for the market development of grass-based businesses. Likewise, the representatives call for further promotion of bio-based products, strategic partnerships, and the creation of clear rules and regulations that can guarantee clean and sustainable products. Product certification was also mentioned as a critical factor for business performance.

Environmental considerations

The products replace many existing and less sustainable (and sometimes imported) products with local sustainable alternatives. Grasslands can help offer carbon sequestration opportunities, promote erosion control and promote eco-systems services.

Social Considerations

Development of new rural business models by improving the utilisation of grasslands. The products can improve local resilience.
