Professor Sondhi Kotchawat, an expert in environment and health Environmental Scholars Club There is an important question that the “government” must rush to answer…in the case of the warehouse storing “chemicals” and “industrial waste” of the Winprocess Company in Ban Khai District, Rayong Province, which was seized for litigation over a fire. severely It causes a huge impact on the environment and public health. An important question arises after the fire is put out…which agency will be responsible for removing the chemical and industrial waste that burned down? Including many of these ashes to be disposed of. And who will pay the expenses? “If the moving process is delayed and there is rain or strong winds, It will cause the washing and washing of chemicals from the factory into people’s agricultural areas. It also turns into dust that causes an impact on people’s health.” Two… how long will it take? To prove that the fire occurred itself or was caused by arson. Three… Who will pay compensation for medical expenses for the affected people both in the short and long term? Four… Who will pay? Pay compensation and restore the people’s land, as well as restore natural resources and the surrounding environment. Five…Who will pay for the firefighting equipment? Including the cost of water and the cost of chemicals used for spillage…Should there be a need to improve and reform laws regarding the management of hazardous industrial waste? how? Continuing on to…hot issues Observations on rushing to transport slag “Cadmium waste” returns to the landfill at the originating factory in Tak Province. Professor Sondhi emphasizes that in transporting large amounts of hazardous toxic waste… a plan should be prepared to assess the risk of all forms of spillage occurring. From donning two big bags, transporting it onto a trailer, taking the waste to the storage pile at the ore processing plant, stabilizing the waste, hardening it and testing water absorption, preparing the transport pit. Move and need to prepare an emergency plan. A plan to deal with incidents in the event of a leak, such as a transport truck causing an accident with cadmium spilling, rain falling while moving, rain falling into the prepared pit, as well as a plan to communicate with the public at every step of the moving process. …Has the plan been prepared or has it been rehearsed?…If something happens, the Ministry of Industry may not be able to handle it. The next issue…is it too early to hurry and transport the cadmium waste back to Tak Province and… Has urged Bound and Beyond Company Limited to prepare to receive ore waste to store in the ore processing plant. Preparation of Secured Landfill holes despite the fact that this factory has withdrawn machinery and equipment. And it’s been an abandoned factory since 2017? Because there is no “zinc ore” to smelt, it is not as professional as Factory No. 101, used for landfilling this dangerous toxic waste. Therefore… Precipitation without preparation and careless operation may lead to cadmium residue contamination. Should there be a 3rd party expert involved in the audit…is it true or not? Is it true that the transport of such waste is over a distance of more than 300 kilometers and that the traffic police will lead the way forever?…is there any follow-up? With a GPS system, but can it be done all the time? Including government agencies, will they really be able to join the inspection at any time?” If the originating company in Tak Province requests to cancel the R.N.4 certificate because there is no longer any zinc ore to smelt. Who will take care of the landfill? Who will monitor the quality of groundwater and surface water? And how can you be sure that in the future HDPE plastic sheets at the bottom of the hole will not tear or leak, the hole will not crack, the cement will not crack, the soil will not subside, and the waste will not contaminate important groundwater…if it is the waste disposal plant number 101 according to the contract? There must be hedging money placed in the fund and a contract to take care of the landfill for at least 30 years. At this point it is also known that…transporting hazardous industrial waste such as cadmium waste …According to international standards, how do they do it? The first point…packaging dangerous products or industrial waste such as cadmium slag. Zinc slag, aluminum, mercury must be packed in big bags made from 100% polypropylene material, tear resistant, certified by the United Nations for transportation…there will be a UN symbol affixed to the bag. It is clearly called the “UN Mark” which can confirm that it has been tested with an internationally accredited organization and has a clear certificate that it has passed at least 4 tests: Drop test. ) and when lifting with a crane, must not tear. Next…test the durability of stacking (stacking test), test the leak proof properties of the bag (Leak proofness), test internal pressure resistance ( internal pressure test) For trucks transporting highly toxic waste, the system must be closed on all sides. There is a logo showing the type of waste and a UN Number as a code for emergency response. The rear and sides of the truck can be opened. In order to use a crane with a handle to move the Big Bag easily, the “Big Bag” containing cadmium slag that was sent and is about to be sent back to landfill in Tak Province probably does not meet UN or UN standards. Mark because there is no UN seal and the transportation may not be up to international standards. When the first lot was transported, the chain on the handle was already broken… which is against the criteria for the hazardous waste transportation system according to international standards. The next issue… What are the standards for storing and burying hazardous waste according to international standards? Starting with the building or warehouse, it must have a roof to protect it from rain. The floor must be compacted, not rough and covered with high density plastic. Difficult to tear…can be highly waterproof or HDPE (High density polyethyline plastic) with drainage holes to the wastewater treatment system. The inside of the building should be well ventilated. Must not be damp…For a permanent landfill, the floor must be compacted, waterproof clay with a size of 1×10-9 centimeters per second. and covered with 2 layers of HDPE sheets…put in the residue that has been stabilized with lime and hardened by covering it with cement. It must be taken for a leachate test in the laboratory first. Once dissolved in water, no heavy metals will dissolve above the standard values. set The waste that has been stabilized and hardened can then be placed in the pit. When the waste is filled, the hole is filled with clay until the pond is full, then the hole is closed with 2 layers of HDPE Plastic, then covered with another layer of cement…What are the Thai standards? How tight or risky are they? You’ll have to keep watching and don’t blink. Don’t let anyone say that it’s like the case… where a man fell from a 15 meter deep electrical conduit and died in the middle of Lat Phrao Road. Under the Yellow Line Opposite the mouth of Soi Lat Phrao 49, Lat Phrao Road, Bangkok. The pipe uses plywood to temporarily seal the pipe’s mouth. “Bangkok” is an abbreviation for “Who will dig it and why?”. Click to read more column “Scoop Page 1”.
