We are primarily concerned with the environment and pollution of water. We provide chemicals for treatment of wastewater, sludges, raw water, boiler water, cooling water, and swimming pool.

The Principle of Water Treatment Part 3

As part of our last series, we will focus at some time of the attention given to the enviroment matters. Enviromental legislation has been enacted in most countries and the standards have been made more stringent than ever including Malaysia. In our country DOE (Department of Enviroment) is empowered under the Enviromental Quality (scheduled Wastes) Regulations 1989, prescribed a listing of 107 categories of toxic and hazardous wastes defined as "scheduled wastes." And in 1993 the goverment introduced the legal control on import.export of scheduled wastes.

DOE, Ministry of Science, Technology and Enviroment, Kuala Lumpur reported that in 1998, the generation of hazardous wastes in Malaysia was about 398,517.95 metric tonnes compared to 279,510.9 metric tonnes in 1997. The major generators of hazardous wastes were metal finishing, chemical, electronics and electrical, printing and packaging. The wastes were solids, liquids and semi solids with different chemical compositions.

As part of the goverment project, in 1995, Kualiti Alam Sdn. Bhd. was given the exclusive right to operate an intergrated WMC (Waste Management Center, Bukit Nanas) for 15 years. The plant is modeled after a similar plant in Denmark using Danish technologies. WMC had all the facilities required for the intergrated waste management up to the final disposal stage. However, it cannot accept radioactive, explosive and pathological (from hospital) wastes. The cost for the acceptance of the disposal waste varies depending on their toxicity.

ENVIROMENTAL QUALITY ACT 1974

ENVIROMENTAL QUALITY(SEWAGE AND INDUSTRIAL EFFLUENTS)

REGULATIONS 1978

[Regulations 8 (1)]

LIST OF CATCHMENT AREAS WHERE STANDARD A APPLIES

1. The catchment areas referred to in this regulation shall be the areas upstream of surface or above sub-surface water supply intakes, for the purpose of human consumption including drinking.

Conclusion:

The consequences for not managing the waste properly will expose us to the risk of having to pay the higher price of neglect.

Prevention is always better than cure; that is, it makes a lot of sense, economically,enviromentally and socially, to prevent enviromental degradation at the onset rather than rectifying it after it has happened.

This is the part of members commitment to help the SMI-Industry to be aware of the enviroment issue via knowledge sharing.
