Thai energy regulators (DOEB) plan to standardise pyrolysis production, quality and safety rules, after the Middle East war pushed the government to revisit plastic-to-oil fuel. The oil works as a substitute for industrial boilers and furnaces, but not directly in most cars or diesel engines without refining. Six refineries have already cut Middle Eastern crude from 58% to 30% of imports. For an SME, this is a signal to watch rather than act on: if you run boilers or furnaces, a cheaper alternative fuel may appear once standards are published. No deadline or cost change is in force yet.
