Polyethylene is the largest-volume synthetic plastic
and its chemical inertness makes it difficult to degrade. Recently
Zheng Huang
Zhibin Guan and coworkers reported a tandem catalytic cross alkane metathesis method for highly efficient degradation of polyethylenes under mild conditions. With the use of widely available
low-value
short alkanes (such as petroleum ethers) as cross metathesis partners
different types of polyethylenes undergo complete conversion into useful liquid fuels and waxes. In addition
the degradation product distribution (liquid fuels versus waxes) can be controlled by the catalyst structure and reaction time.
