The Group takes spent oil, including polychlorinated biphenyl ("PCB") contaminated oil, as the primary feedstock, which is then processed at its two plants enabling 99 per cent or greater recovery of oil for reuse while also eliminating PCBs, a toxic additive banned under international regulations, without environmentally harmful emissions.
