Allied’s  focus is on providing clean products and services to industrial clients, in particular in the oil, gas and coal industry. In addition to engineering services, our main products are high quality re-refined lube oils and synthetic gas produced from gasification. Our proprietary coal gasification process can be combined with the sequestration of CO₂, which can be used to enhance the recovery and production of crude oil. In China we manufacture catalysts for the removal of nitrogen oxides to serve the domestic and international markets. We provide engineering solutions for the removal of nitrogen oxides, sulphur and other particulates from industrial waste gases and to the water industry by designing and building water and (industrial) wastewater and sewage sludge treatment plants. We are also a participant in the growing market of trading and generating carbon credits and emission certificates under the Kyoto Protocol.
