Customer

The Municipal Company of Waste Management Ltd in Katowice provides a framework of service activities such as:

  • The collection and transport of waste
  • Selective collection and utilization of waste
  • Composting organic waste
  • All year round road maintenance
  • Automotive diagnostics

Requirements

The requirements were to build a waste sorting plant on the basis of the existing composting and sorting plant located in Katowice.

The input material is mixed dry household waste and selectively collected packaging material, i.e. plastics, metals, paper and cardboard.

Solution

  • The plant is designed according to the tender specification and has a maximum design capacity to sort 65,000 tonnes of mixed waste per year (on one 7 hours shift).
  • The plant includes five REDWAVE machines in three sorting steps.

Process

The sorting starts with manually separating elements which can interrupt the process (i.e. rubble, tyres, large materials, glass, large cardboard, foil and dangerous waste). After that the remaining waste stream is sieved and divided into the following fractions: 0-80mm, 80-160mm, 160-300mm and
The two remaining fractions will then be sorted with 2 REDWAVE NIR machines. The first NIR sorter is used for the 80-160mm fraction and the second NIR machine for the 160-300mm fraction. Both RED-WAVE machines are arranged in parallel and are used for sorting material to be used as an RDF (refuse derived fuel).

Thereafter the remaining material will be scanned by another 2 REDWAVE sorting machines, which will separate paper and cardboard. All sorted materials will be further checked and cleaned manually to en-sure quality control. Residual material after these REDWAVE sorters will be shredded and sent to the RDF storage warehouse. The last REDWAVE NIR machine is used for sorting PET bottles from both fractions.

Testimonial

The statement from the Katowice facility Mr. Arkadiusz Teodorowski: “REDWAVE’s sorting machines sup-plied by BT-Wolfgang Binder GmbH are hi-tech equipment, which fulfil our company needs. We were more than satisfied with both delivery arrangements and service. In our opinion BT-Wolfgang Binder GmbH is a reliable and experienced business partner, who we would recommend to others.”
