China's attempts to curb emissions from energy plants in Shandong province are putting small and medium-sized oil and chemical businesses under pressure as refineries struggle to comply with new standards. While random environmental inspections formerly scrutinised large state-owned facilities, the authorities' targeting of smaller companies has caused 30 independent refineries to shut since mid-July. Additionally, a number of chemical plants making propylene oxide (PO), PVC and rubber tyres in the region have stopped production, according to industry sources and market analysts. The move is part of an effort by Beijing to reduce air pollution that causes respiratory problems among residents living near its major cities.
