In 1993, TITECH developed the world’s first near-infrared sensor for waste and recycling sorting. Today, TOMRA Sorting Recycling (formerly TITECH) is recognized as the world leader in sensor based sorting. With a strong focus on research and development, TOMRA Sorting Recycling leads the market in the introduction of cutting-edge technology for the sorting of recyclables.

TITECH-TOMRA

As a technology leader TOMRA Sorting continues to be a pioneer in sensor-based sorting in a variety of industries. With more than 110 years of combined sorting and industry experience, and over 11,500 units installed in more than 80 countries, our expertise allows us to deliver high-performance sorting and analytical solutions to our customers.

In the recycling industry, we use infrared technology to “scan” materials such as mixed plastics (PET, PP, PVC, and others), mixed paper, glass, C&D, and MSW materials. Using this innovative technology, our systems can also sort by size, color, weight, and shape, resulting in increased efficiency and lower labor cost.

VAN DYK Recycling Solutions supports and markets TOMRA Sorting Recycling optical sorting units for single stream, e-waste, plastics, and paper markets. Customers can send their materials to the TOMRA sorting test center to see them processed under true operating conditions prior to investing in TOMRA sorting technology.

TOMRA Sorting Recycling Advantages

TOMRA Sorting Recycling has more than 4,400 units operating in 40 countries. The AUTOSORT has been in production for over 15 years and is a mature product that has gone through several revisions and improvements. The entire TOMRA Sorting Recycling family of products are developed and manufactured in Europe.

TOMRA Sorting Recycling machines have the most scans per second of any optical sorting company. Expected recovery and purity rates are in the 90%–99% range.

Reliability

Over the past five years, our AUTOSORT has had an availability of more than 95% where maintenance protocols were properly followed.

Working Principle:

Resolution Comparison

TOMRA Sorting Recycling’s superior resolution increases performance. See the illustrations below.

Optical Multiplexer (typically used by competitors)

This configuration technique results in poor resolution, for the following reasons:

  • One line is scanned in a fixed raster
  • Standard multiplexer takes a maximum of 1,600 measurements per second
    • Measuring heads: approx. 32
    • Line frequency: approx. 50 Hz

  • Distance between measuring spots at conveyor speeds of 400’/min. and 3.2′ width:
    • 40 mm or 1.5″ (in conveyor direction)
    • 31 mm or 1.2″ (orthogonal to conveyor direction)

Easy Maintenance

Adjustable valve block

  • Software monitors the valve block position and adapts its parameters

Easy to remove lamp rails

  • Easy cleaning and replacing of lamps for faster maintenance
  • Increased (or higher) reliability of the system

Self Diagnostic Tools

Pressure sensor to detect defective valves

  • Electrical failures
  • Blocked nozzles
  • Broken valves
  • Low pressure

Lamp failure check

  • Done in software by using the intensity
  • Detects failures of a group of lamps and wrong adjustment of the lamps
