Abstract
The two major malodour problems faced by the raw rubber processing factories in Malaysia are teh hydrogen sulphide gas from anaerobic ponds treating effluent from latex concentrate processing factories and the exhaust gases from the drying stage of the SMR processing factories. The maloour due to release of hydrogen sulphide gas ponds to fully anaerobic submerged aeration ponds. The exhaust gases released from the SMR driers contained volatile fatty acids and other volatile organic compounds which originated from the bacterial breakdown of non-rubbers in the latexduring the formation of cup lumps and during the storage of cup lumps prior to processing. The extent of malodour is described by determining the odour concentration in the air samples collected by dynamic olfactometry. The results of MRB/DOE survey from 2003 to 2004 indicated that the average odour concentration in the drier exhaust gases of factories which process SMR from field grade materials was 74 870 ou/m3 and from driers is controlled by using the water scrubber system. Other alternatives methods for controlling malodour from SMR processing factories are also described.
