Environmental street

Bring your discarded goods and materials to the waste disposal site at the Ecopark. One of our staff will welcome you at the entrance. Together we will examine your cargo and advise you on the best route across the site. We will also tell you which goods and materials can be reused or repaired and which you can dispose of at the waste disposal site.
> Find out more about how the waste disposal site works
> Consult the regulations for environmental centres to bring in waste and raw materials


At the Ecopark, we give as many goods and materials as possible a second chance. At the waste disposal area, there is a special area where you can neatly put your things that could get a 2nd chance. In the workshop, people who need a helping hand work under supervision to repair or make up as many goods as possible, such as furniture. Of course, you can take back your repaired items yourself for a small fee. We sell donated items in the regional thrift shops or in the webshop of The Companion.

Sustainable building materials

At 2e Kans Bouwmaterialen you can buy sustainable building materials that you want to give a second life. Take a look in the webshop of 2nd Chance Building Materials to the current supply of circular building materials. You can also drop off your reusable building materials.

Recycling centre

KoreNet converts goods that cannot be reused as products into reusable raw materials. For example, KoreNet separates your delivered wood into reusable wood and wood that goes to the chipboard industry. KoreNet also uses a sorting plant to separate raw materials delivered mixed, such as wood, plastic and metal for recycling.


From the education room, you have a view over the Ecopark. Here you can learn more about the circular economy and how you yourself can contribute to a better environment. The education room can be visited by appointment and is suitable for groups, such as school classes. Guided tours of the Ecopark are also possible.
