Non-processed wood. TOMRA’s Wood A vs Wood B application uses deep learning technology to sort and extract impurities that couldn’t previously be detected, making it possible for the first time to detect, analyze and sort every different wood type, therefore cleaning up the real wood fraction. The primary application for TOMRA Recycling’s new solution is sorting Wood A — non-processed wood — from Wood B — processed wood products such as MDF (medium-density fiberboard), HDF (high-density fiberboard), oriented strand board (OSB) and chipboard.

Sensor-based sorting specialist, TOMRA Recycling, has further strengthened its offering for the global wood recycling sector by using deep learning, a subset of artificial intelligence, in wood recycling applications.

TOMRA Recycling has been a frontrunner in the global wood recycling sector for more than 10 years. The company's X-TRACT solution quickly became popular with chipboard manufacturers to produce a clean recycled woodchip fraction by sorting and separating out the inert material (glass, stones, ceramics, etc.) and metals. Once the X-TRACT unit has removed these impurities, the recovered woodchip is of sufficiently high quality to be used in the production of standard chipboards, according to the company.

Achieving Higher Purity Levels

In recent years, however, TOMRA Recycling has been approached by an increasing number of customers who are looking to use recycled wood of a much higher purity level in their production processes. To achieve these specific purity requirements, in addition to removing the inert material and metals in the infeed stream, other impurities including engineered wood composites as well as polymers, would have to be removed.

As these materials are not distinguishable using x-ray technology, the X-TRACT unit was unsuited to this sorting task. Determined to help these customers and recognizing a potential gap in the market for a solution which would allow companies in the wood recycling sector to optimize their wood sorting processes, TOMRA Recycling's deep learning experts developed an application that combines TOMRA's AUTOSORT unit with its deep learning-based sorting add-on, GAIN.

TOMRA's Wood A vs Wood B application uses deep learning technology to sort and extract impurities that couldn't previously be detected, making it possible for the first time to detect, analyze and sort every different wood type, therefore cleaning up the real wood fraction.

TOMRA is the first company in the world to use deep learning technology to detect and separate different wood types, targeting Wood B (processed wood composites) as impurities to leave a clean Wood A fraction (non-processed wood), or, depending on customers' requirement, producing individual high purity engineered wood composite fractions out of the infeed stream, the company said.

Philipp Knopp, product manager at TOMRA Recycling, said: "Wood recycling is a fast-evolving market, with increasingly stringent legislation being introduced in a number of regions globally to move towards a more circular economy model. Our AUTOSORT with GAIN solution uses deep learning technology to create a robust and flexible solution, which we are confident will be welcomed by wood goods producers across to globe. It will also enable our customers to future-proof their operations as they will be better equipped to adapt and react to any future changes in the global wood recycling market such as new legislation. We are delighted to be the first in the market to offer this artificial intelligence-based solution."
