The stocks of a whole series of materials are shrinking rapidly. The use of fossil based feedstock for production of materials and products has a detrimental impact on the environment. The replacement of existing materials with reusable bio-materials and the transformation from fossil based to bio-based materials become the challenge for future generations. However, fitting the new bio-materials in the current economic model, and realizing synergies between bio-economy and the circular economy to create a more sustainable economy, is far from easy. Many questions remain unanswered. (read more)
- What is the added value of bio-based products (and plastics) to the circular economy?
- How to measure the benefits of bio-based products for climate change? What indicators, what methods?
- How can compatibility problems between feedstock, energy and food be dealt with, as well as impacts of biofuels on indirect land use change?
- How can compatibility problems between bio-based plastics and fossil based plastics (e.g. on recyclability, on risks for the quality of recyclates) be dealt with?
- How to deal with biodegradability and compostability definitions in ‘real world’ conditions (with e.g. the possible risk of microplastics and ‘plastic soup’)?
- How can the use of biowaste (e.g. compost in agriculture) be turned in a viable case not only for the environment but also financially?
