Metal Casting Technologies : December 2007
METAL Casting Technologies December 2007 44 Environmental Report 22 billion Baht to be spent over 4 years to cure these problems, most of this sum being needed for equipment to reduce toxic emissions. The Map Ta Phut estate was originally set up in 1981 to accommodate the newly developed petrochemical industry. Since then the petrochemical and other industries have expanded considerably such that toxic emissions have now reached critical levels. The main problems are reported to be leaks of VOCs from storage tanks and pipe-work in chemical and petrochemical plants. At present Thailand does not have local maximum emission limits for VOCs so the Industrial Estates Authority of Thailand (IEAT) and the DIW are now said to be working on regulations to reduce emissions. They are also implementing plans to reduce the volume of waste water from industrial estates. To encourage industry to reduce pollution the Thai Board of Investment has said that it will offer tax incentives to companies. Companies that do not comply with forthcoming emission standards to be set by the Natural Resources & Environmental Board will face financial penalties in the form of emissions charges to be levied by the DIW. It must be recognized that most of the foundries and diecasting operations on the Eastern Seaboard are modern joint venture companies situated on the newer estates . These "foundries in a garden" are setting good environmental examples to the rest of the Thai foundry industry which is mainly sited around Bangkok. Like the other parts of Thai industry, the non joint venture SME foundries need to make considerable improvements in process control, defect reduction and energy efficiency let alone in environmental and health & safety aspects. Most SME foundries have little knowledge of pollution control and environmental management and continue to be completely unaware of the health dangers presented by the raw materials that they use, and by the emissions and waste from their processes. KMUTT, Kasetsart and other training providers have a lot of work to do and the next Thai government must find the right "sticks" or "sweeteners" to encourage the foundries to take part. "CARBON FOOTNOTES" At present under the Kyoto agreement Thailand is classed as a small volume greenhouse gas emission country, it accounts for around 0.7% of total global emissions. The Thai Ministry of Industry has expressed concern that in the next phase of Kyoto Molten liquid iron being poured.
