Control and traceability

The system of selective collection, sorting, and recycling of household packaging waste only works when all parties involved deliver optimal quality. In order to guarantee this, Fost Plus organizes objective quality controls. They have a positive impact on the quality of the services, the materials, and the recycling process.

At the recycling companies

Independent inspection agencies regularly perform audits of the recycling companies to check whether the supplied materials are actually recycled.


In order to monitor the flow of data between all of the partners as efficiently as possible, Fost Plus has developed a Web application. All of the data about collection, sorting, and recycling is easily traceable via a central database.
