2. Refining capacity limited by environmental restrictions
Many refiners in China are still under scrutiny and increased environmental checks from the Chinese authorities.
In many cases the inspections have required the installation of environmental treatment measures – such as neutralising chemical gas emissions or waste water treatment – pushing up costs for refiners, which are being passed on to buyers in what is becoming a tight margin market.

Very soon the water treatment side of our business is going to explode.
