AI-based waste-sorting system wins Young Inventors prize

Two UK-based intelligent-recycling entrepreneurs have won first place in the inaugural Young Inventors prize, awarded by the European Patent Office as part of the European Inventor Award 2022 ceremony.
Imperial College London graduates Peter Hedley (27 years old) and Victor Dewulf (25) won the Young Inventors prize 2022 for their efficient AI-based waste-sorting system.
The European Patent Office honoured the British-Belgian duo for their computer vision system that is trained to recognise waste items on a conveyor belt, equipped with a robotic arm to pick out valuable material. The invention increases the speed, accuracy and purity of waste-sorting.
Their system has already been rolled out to recycling facilities in the UK and Europe through the inventor duo’s London-based start-up Recycleye, increasing the volume of recycled waste and making recycling more financially attractive.
Dewulf and Hedley’s system consists of two parts, which can be used separately or together. The waste-recognition system uses a cellphone-quality camera mounted above conveyor belts to take photos of the passing waste and send them to an algorithm, which ranks them for picking priority. Instructions on where to pick up and place the waste are then sent to a six-axis robotic arm for sorting. The entire solution can make 55 successful picks from a conveyor belt every minute.
The idea for the invention began when Dewulf visited a recycling facility as part of his degree at Imperial College London. He was surprised at the level of manual labour involved, making sorting waste prohibitively expensive and limiting the volume of recycled material. Dewulf suspected that a type of artificial intelligence called computer vision could improve the process and turned to his friend Hedley to partner on the project.
The pair began developing their system in the garage of Hedley’s parents in Poole using a camera, a treadmill and a pile of dumpster-dived trash. After successfully training their initial computer vision system, Dewulf and Hedley founded their company, Recycleye, in 2019. They have since raised millions of pounds in funding and have so far deployed 17 vision systems and five robot arms, with more in the pipeline.
Dewulf and Hedley see their work as a key step in creating a sustainable economy. “Applying computer vision and new technologies like robotics means that we can start accelerating the automation of (the waste) industry,” said Dewulf. “Ultimately that means accelerating our economy's transition to a circular economy to the point where our removal chains can be merged back into our supply chains.”
António Campinos, president of the European Patent Office (EPO), said: “Victor Dewulf and Peter Hedley are using cutting-edge AI technology to tackle a substantial problem – how to drastically reduce our waste. By increasing the likelihood that waste will be recycled, their innovation contributes to a cleaner world for us all and this is exactly the type of sustainable venture that the Young Inventors prize was set up to recognise.”
The team was honoured at a hybrid event watched online by a worldwide audience to announce the winners of the 2022 edition of the European Inventor Award, one of Europe’s most prestigious innovation prizes. The EPO created the new Young Inventors prize under the auspices of the European Inventor Award especially for innovators aged 30 and under.
The award offers a monetary reward to young innovators who have developed solutions that contribute to the United Nations’ Sustainable Development Goals and positively impact our lives. Dewulf and Hedley were named one of two first-prize winners alongside Erin Smith, a US-based Parkinson’s researcher. Both the duo and Smith will receive a cash prize of €20,000 each.
