Abstract
A method for depolymerizing polyolefins. The method includes a sulfonation step including contacting a polyolefin with a sulfonating agent in the absence of an organic solvent to provide a sulfonated polyolefin and a bond cleavage step including contacting a metal catalyst and an oxidant with the sulfonated polyolefin. A carbon-carbon bond of the sulfonated polyolefin is cleaved to provide a bioavailable carbon product wherein the bioavailable carbon product is a carbon source for microbial growth.
