From plastic waste to circular plastics

Thema:
Circular plastics

Less plastic waste, lower CO2 emissions, and less use of fossil raw materials. To achieve this, we’re doing independent research on circular plastics. From innovations for new plastic product designs to sustainable technologies for recycling plastics. With circular plastics, we’re contributing to a more sustainable future.

The up- and downsides of today's plastics

Increased use of plastics

Plastics are strong, flexible, and lightweight, and these versatile properties mean that their use continues to increase. Between now and 2050, plastic use is expected to rise from 350 million tonnes to more than 1 billion tonnes, due among other things to:

  • the growth in population and wealth in Africa and Asia
  • the use of more and smaller packaging
  • societal developments, such as urbanisation and family composition.

This brings major challenges, such as plastic waste, use of fossil raw materials, and CO2 emissions. We therefore need a systems transition. We’re keen to contribute to innovative solutions through research on circular plastics.

Increase in microplastics

With the increasing use of plastics, more and more microplastics are formed as well. These solid particles, smaller than 5 millimeters, are created through wear and tear during use, and are formed through the degradation of plastic waste present in the environment.

Microplastics are potentially harmful to humans and the environment. Therefore, the Dutch government applies the precautionary principle, whereby we must minimize the use, formation and spread of microplastics.

By 2022, we have conducted extensive research on microplastics and identified the major contributors to microplastics and measures to reduce microplastics.

Project

Circular plastics

For the transition to circular plastics, we take a close look at the entire supply chain. From the impact of different scenarios on CO2 emissions and material use to health and economic feasibility. To this end, we combine our expertise in life cycle analysis and life cycle costing with technological knowledge of recycling techniques. We make the right choices – systemic and otherwise – based on impact assessments. The guiding principle is the preservation of economic, ecological, and societal values in the chain.

Laboratory research and advice

Because successful recycling starts with good design, we develop short, medium, and long-term plans for circular plastics. For this purpose, we combine laboratory research, pilot tests, and advice. We’re also developing technologies to improve sorting and mechanical recycling. In the Brightlands Materials Center, we develop new packaging that’s more recyclable. And in the public-private partnership Brightsite, we create, for example, industrial demos in the area of chemical recycling.

Chemical and physical recycling of plastics

In other research, we’re developing chemical recycling technologies for plastics. We do this through depolymerisation and physically through dissolution. This is how we separate monomers or polymers from additives such as flame retardants.
