Turning waste and biomass into value across Europe’s bioeconomy
The bio-economy covers activities that use biological resources to create sustainable products, energy, and services. In the European Union, this sector already generates around EUR 2.7 trillion and supports 17.1 million jobs. Even so, a large share of its potential remains unused. According to the European Commission, the EU bio-economy could grow by about 18% each year if the right policies, investments, and technologies are put in place.
The newly published EU Bio-economy Strategy is designed to support this growth. Its focus is practical: helping ideas move from labs and pilot sites into real markets. This depends on proven bio-based materials, reliable technologies, and business models that work at scale. Several LIFE-funded projects across Europe show how this can be done by turning neglected resources and waste streams into valuable outputs.
One clear example comes from the Netherlands. The GR4SS project looks at roadside grass, a material usually treated as waste. Instead of discarding it, the project collects grass cuttings and processes them in anaerobic digesters. This produces green biomethane, fibre-rich digestate, and soil-substitute materials. Results show strong potential. If ten GR4SS digesters were deployed across the country, they could produce around 25 billion litres of green gas and cut carbon dioxide emissions by about 125,800 tonnes. At the same time, the approach creates new income opportunities in rural areas and reduces reliance on fossil fuels.
In Spain, the ZEBRA-LIFE project focuses on an industrial by-product from the pulp and paper sector known as black liquor. This substance is normally burned to recover energy. ZEBRA-LIFE takes a different route by extracting bio-aromatic compounds from it. These compounds are used to produce renewable antioxidants and UV-filter additives. Testing shows that these bio-based additives can match or even outperform conventional synthetic options. They can be used in products such as cosmetics, rubber, fuels, lubricants, and polymers, showing how industrial residues can feed circular value chains instead of being treated as low-value waste.
Another example highlights how the bioeconomy can restore damaged land. The MySOIL project operates in France, Italy, and Spain, where it applies fungal-based bioremediation to clean soils contaminated with total petroleum hydrocarbons. These pollutants come from fuels and industrial activities and affect an estimated 2.5 million sites across Europe. MySOIL’s approach can remove up to 90% of these contaminants, making land usable again. Compared with conventional methods like incineration or thermal treatment, the bio-based solution uses less energy and lowers costs while delivering strong environmental results.
Taken together, GR4SS, ZEBRA-LIFE, and MySOIL show how the bioeconomy works best when it focuses on real problems and overlooked resources. Grass cuttings, industrial by-products, and polluted soils are not obvious starting points for growth. Yet these projects prove that they can support viable businesses, reduce emissions, and improve environmental quality. By providing solid data on performance, costs, and impacts, they also help policymakers and investors see where scaling makes sense. This kind of evidence will be key as Europe looks to expand its bioeconomy in a practical and sustainable way.
