TOMRA Sorting’s near-infrared technology

TOMRA Sorting leverages near-infrared technology across a range of specialised products to increase revenues and reduce costs and the impact on the environment.

The near-infrared technology is ideal for packaging, municipal solid waste, thermoplastics, paper, commercial and industrial and construction and demolition waste, organic waste, refuse-derived fuel, bulky waste, wood and thermoplastics.

In particular the introduction of the laser object detection (LOD) now allows for sorting materials with no specific infrared signals.

Laser object detection sensors use a 3D laser system to physically detect items the spectrometer can’t detect. This now allows considerably improved removal of contaminants from various product streams.

Its multifunctional Autosort has been upgraded to include a user-friendly touchscreen to allow users to access various sorting programs.

Available through Australian supplier Cemac technologies, the company also offers select TOMRA technology to suit each application.

TOMRA Sorting’s Autosort flake combines colour detection with enhanced material and metal objects simultaneously to offer better purity and yield with the one machine.

Its Autosort fines was built to sort small fractions across multiple applications with a wider mechanical setup.

TOMRA Sorting’s Finder is able to target metal objects using patented z-tect technology which leverages artificial intelligence to detect and ignore disturbing noise and lead to a stable purity and high yield.

View your landfill in 3D

No longer limited to intensive gaming or high-end architecture, virtual reality is making in-roads in the landfill sector.

Landair Surveys, a leading surveying firm in Australia, has introduced a new way for their landfill clients to interactively view their site data.

Previously, waste managers relied on 2D plans and concept drawings to visualise the relationship between existing site conditions and future operations. However, the rise of 3D viewing platforms has led to the possibility of creating virtual landfills where many different spatial data sets can be viewed simultaneously.

The surveyors at Landair now offer prospective clients virtual landfill models that can be tailored to individual landfill sites or operational requirements. The models can be as simple as an online visual tool to a downloadable interactive viewer allowing the user to take basic measurements and create clipping planes.

  • Examples of current virtual files created for landfill operators include:
  • Design top of waste contours overlaid on existing landfill surfaces
  • Design clay sideliner files overlaid on existing rockface surveys
  • View of proposed finished top of cap levels from site boundaries
  • Month by month landfill cell flyover comparisons
  • Composite as built clay liner and subgrade checks.
