Dr Hunyak and his colleague Prof Taras Markiv visited the University of Leeds to share academic research and understand how technology pioneered in Leeds could help rebuild their home.
Prof Markiv said: “Two years ago a missile fell not far from my apartment – all of the windows were shattered, our front door was blown out – my children were scared.
“I would like to say that I have done my best to rebuild our country.
“We will bring the information from the UK and share with our colleagues.”
The technology includes a mobile advanced dry recovery processor, which fits on the back of a lorry and travels to bomb sites to recycle materials on-site.
At each location it upcycles concrete from bombed buildings by separating the damaged material into sand, stone and cement.
The system will be deployed in Ukraine through the Safe, Sustainable and Swift Reconstruction of Ukraine (S3RoU) programme.
S3RoU is backed by the InnovateUkraine programme, led by the Foreign, Commonwealth and Development Office, and is funded by a £16m investment from the UK government.
