Coffee grounds contain many nutrients which are excellent for growing mushrooms. This secondary raw material is even ready for use, having been sterilised at 80 to 90°C by the coffee machine. What's left once the mushrooms have been collected is a good fertiliser.

The European NONTOX Project aims to eliminate hazardous and unpleasant substances from plastic waste and thus convert non-recyclable plastics and recycling waste into new resources.

Leadax uses high-tech material and production knowledge to develop and manufacture 100% circular materials out of discarded PVB for waterproofing buildings.

Schijvens has been producing corporate uniforms for more than 150 years now. In 2017, they began collecting customers' old clothing, shredding it and mixing the textile fibres with shredded PET-polyester ones from sportswear, fishing nets and bottles.

Toast Ale was founded in 2015 to reduce demand for natural resources by replacing virgin barley with surplus fresh bread.

The E-waste Race is an educational competition between ten primary schools to collect old electronic devices.

They then start collecting e-waste and the school which collects the most wins an educational - and fun! - school trip.

Back in 1931, EMMA was founded as a social enterprise for injured workers from the Dutch State Mines. Hence, social entrepreneurship is in the DNA of EMMA Safety Footwear. Today, EMMA still employs about 100 people who need some additional support in the labour market. Making sustainable safety shoes was, therefore, a logical next step in EMMA’s journey towards a positive footprint.

SNEW has developed a circular system reusing the raw materials in existing equipment. It aims to give business telecoms and IT equipment a second life. Companies which hand over their old ICT equipment get either maintenance for their current equipment or money for the old equipment.

CuRe has discovered a smarter and scalable technology for creating a fully circular polyester chain. It rejuvenates any type of used polyester by removing the colour and converting it into clear pellets with the same properties as virgin grade polyester.​ In July 2020, a pilot plant in Emmen (Netherlands) was opened for rapid scale-up.
