In Malaysia

Malaysia's palm oil mills, run by plantation groups and independent millers, process fresh fruit bunches round the clock through sterilisers, presses, clarification and boiler stations. Process staff often start as station operators and work up to shift or mill supervisor. Anyone running the boiler must hold a DOSH steam boiler operator certificate.

How people get into it here
Start after SPM as a mill operator, or with an SKM or diploma in mechanical, electrical or chemical/process engineering. MPOB runs a mill supervisor course (needs two years' mill experience) and the DIPOM diploma (SPM plus two years in a mill), and DOSH certifies steam boiler operators (Grade 1/2).
