Once the toxic plastic is present, its production, use, disposal and regeneration process may release toxic and harmful substances continuously.
National Development and Reform Commission open to the community to seek 'plastic garbage pollution prevention and cure' of the proposal to come to an end, as an environmental activist, I also have a personal recommendation to submit to the NDRC, 'strict control of toxic plastic chemicals added to strictly regulate the toxic plastic Treatment to prevent the entry of harmful substances into recycled plastic products'.
There is no doubt that to solve the problem of plastic garbage pollution, it is necessary to take measures at the source to reduce the amount of waste plastic recycling through waste separately collected together, and then processed to make it into recycled plastic and recycled plastic products .
However, if some plastic products were originally produced from 'poisonous plastic' from the outset, the recycled plastic from which they are derived is likely to be a toxic plastic, and the related product remains a 'toxic product'. Further down, if the entire process does not change, 'recycled plastic and plastic' may also become 'recycled plastic and plastic'... So cyclically, poisonous plastics will last long in people's lives.
There are two root causes of toxic plastic problems: First, certain types of plastic under certain conditions, itself toxic.PVC is the most typical one, although this artificial resin itself is non-toxic, but Its polymerization raw material vinyl chloride monomer is a known human carcinogen.Scientific research shows that not only some PVC plastic products will have a certain vinyl chloride monomer residues in some physical and chemical conditions, such as Regenerative melting process, there will be more vinyl chloride monomer is released.
The intentional addition of toxic chemicals is another major cause of toxic plastics. To achieve the specific properties of plastics, their products perform specific functions and plastic manufacturers can add various chemicals to their primary plastics as needed, including plasticizers, colorants , Fillers, heat stabilizers, lubricants, etc. Many of these additives are quite toxic, such as bisphenol A, phthalates or phthalates, a variety of brominated flame retardants and the like.
Whatever the reason, once the poison plastic is present, its production, use, disposal and regeneration process may release toxic and harmful substances continuously, causing environmental pollution and harming people's health.
Last year, an international environmental agency released a report on the levels of toxic chemicals in children's plastic products in many countries around the world, and the result was worrisome. In all samples, a fairly high percentage of high concentrations of octabromide Diphenyl ether, decabromodiphenyl ether and hexabromocyclododecane - three of the persistent organic pollutants that are already under the control of international conventions However, according to expert analysis, all three chemicals are classified as bromine Flame retardants, according to the requirements of the relevant product material standards, should not be added to the plastic, indicating that the raw materials used in these toys are likely to be the original waste plastics or recycled plastics containing brominated flame retardants.
It is even more worrying to us that in the above report, quite a large proportion of the samples purchased in the Chinese market could be included in the scope of 'poisonous toys' and 'poison products'. The products involved include plastic Rubik's Cube, plastic rain boots, plastic slippers, plastic Little yellow duck and so on.
Thus, an important part of the prevention and control of plastic garbage pollution is to prevent the intentional addition of toxic chemicals in plastics with the plastic recycling process into the new plastic products, as well as to prevent plastic in the process of conversion of new harmful substances.
To this end, NDRC should give priority to restricting the use of toxic chemical additives at the source when formulating overall prevention and control policies on plastic garbage. At the same time, it is required that product quality departments and environmental protection departments should carry out the inspection of harmful substances such as plastic products or recycled plastic products System monitoring.At the same time, we must also study the introduction of toxic plastics harmless disposal of the relevant technical standards, so as to maximize the blockade of hazardous substances exposure, so that the plastic recycling industry really become clean up.
