Honeywell International Inc. says it developed a commercially viable method to melt down low-grade plastic waste and turn it back into oil that’s good enough to feed into a refinery.

The maker of chemicals, automation equipment and aircraft parts is teaming up with the Spanish infrastructure company Sacyr SA to build and operate the first plant using the process, a facility they expect will transform 30,000 metric tons annually of mixed plastic trash into refinery feedstock.
