In May-2013 the Australian Pesticides and Veterinary Medicines Authority (APVMA) published a report, informing of their intention to cancel the registration for manufacturing and selling of 24 products containing high volatile ester forms of 2,4-D.
2,4-D is a herbicide and secondarily a plant growth regulator. Agent Orange, the herbicide widely used during the Vietnam war contained 2,4-D. The World Health Organisation (WHO) has classified it as a Class II ‘moderately hazardous’ pesticide. This places it in the same class as endosulfan, lindane, paraquat and toxaphene. 2,4-D is a herbicide used to control weeds in crops, commercial and industrial areas, turf, forestry and waterways. There are now 220 registered 2,4-D products in Australia
In 1995 the APVMA began a review of 2,4-D because of concerns over its potential risk to public health, occupational health and safety, and the environment (including impacts on waterways, non-target animals and plants).
As a waste generator, it is your responsibility to know the types of waste you produce, and to ensure it ends up at a waste facility that knows how to effectively treat it! This is irrespective of whether your waste is disposed, treated, recycled or applied to land.
So, if you have 2,4-D, what can you do about it?
To assist in the treatment of these types of waste, Toxfree has state-of-the-art “hazardous chemical” destruction technology, known as the PLASCON®,
The PLASCON® process produces a high temperature plasma arc by ionizing argon gas in a 150 kW DC discharge between a separate cathode and anode. A mixture of waste and oxygen is injected radially into the plasma at a specially designed injection manifold. This process is known as pyrolysis. Unlike incineration, dioxin formation is avoided by the use of pyrolising conditions and rapid quenching. PLASCON® can achieve Destruction Efficiencies (DE) in excess of 99.999999%.
PLASCON® waste destruction eliminates a wide variety of concentrated organic waste types including PCBs, pesticides, ozone depleting substances such as CFCs, HCFCs, as well as other greenhouse gases, refrigerants and halons. Waste treatment can be either in-process or from a stockpiled feedstock, with a throughput of up to 3 tonnes of waste per day.
Apart from 2,4-D Plascon can destroy many other pesticides including DDT, DDE, Dieldrin, Aldrin, Lindane, Malathion, Heptachlor, Ethion, 2,4,5-T, Carbaryl, Dichlorovos, Chlorpyrifos.
