KKR-backed Viridor, a recycling, renewable energy and waste management company, agreed to acquire Quantafuel, a technology-based energy company converting waste plastics back into low-carbon synthetic oil products replacing virgin oil products, for $101m. "Today marks a critical step on Viridor’s growth journey to build a truly circular plastics economy. Plastics are a key solution in so many aspects of our lives. Advanced recycling processes like Quantafuel’s are essential to ensure those plastics can be recycled again and again. Our proposed acquisition and investment represents the strong commitment both businesses have to ensuring we deliver a better environment," Kevin Bradshaw, Viridor CEO.
