The OIE and King Mongkut
's University of Technology North Bangkok last week announced the results of their study into energysaving methods for manufacturers in these three indus¬tries.OIE director-general Atchaka Sribunruang Brimble said the manufacturing sector accounted for 37.5 per cent of the country
's energy consumption, which was slightly higher than the transportation sector.The study concentrated on downstream chemical products by basing itself on glue and mas
¬ter batch, both key materials in the mixing of colours in polymer pellets.It found that energy account¬ed for 10 to 20 per cent of the pro¬duction cost of the glue and 55 per cent for the master batch.
The report suggests that makers of both raw materials turn to an alternative energy source that gives a worthwhile return in the long run. They should improve their productiv¬ity, which will help them better utilise their raw materials in the production process, Atchaka said.
While Thailand
's plasticinjection firms are highly com¬petitive, the plasticblowing process is less efficient than in other countries.As electricity accounts for about 95 per cent of energy con¬sumption in the plastics indus¬try, manufacturers are encour¬aged to improve their produc¬tion technology so that they maximise their energy efficien¬cy, as well as planning ahead for their energy needs in order to match production capacity more appropriately.
The study also said the foodprocessing industry mainly used energy generated by heat and steam. It suggests manufacturers boost the efficiency of steam generation and shift from fossil fuels to alternative fuels.
