TECH FOCUS: HYPERSPECTRAL IMAGING Trash talk

orting and recycling waste is not only crucial for the planet, it is also big business.
‘One of the key components of waste
sorting is quality of the material you are sorting, so you can resell the material – that’s getting important nowadays,’ Eric Camirand, founder and chief executive of Waste Robotics, noted during a presentation for Imaging and Machine Vision Europe as part of a webinar on hyperspectral imaging.
Recycling centres get paid to receive waste
and sort it. Everything they can separate out to be recycled – or resold if possible – saves on material going to landfill. Te material that’s missed and sent to landfill costs money. ‘Tey’re trying to avoid the landfill cost and capture quality products. It’s all about sorting out quality in the least expensive way,’ Camirand explained. Many recycling centres still rely on hiring people to sort through waste on a conveyor,

which can be inefficient and unpredictable, with material that could be reused sent to landfill. It’s also not a pleasant job. Waste Robotics, based in Trois-Rivières in Quebec, Canada, is trying to automate this process with robotic sorting. Camirand said sorting should be: inexpensive; effective at capturing quality material; precise, adaptable and reconfigurable; predictable and reliable; and something that improves the overall operation, all of
