Recycling of the #5 Polymer Science
In 1970, recycling of plastics from the municipal solid waste (MSW) stream was virtually nonexistent. By 1994, the recycling rate of different types of plastics found in the United States MSW (containers and packaging, durable goods, and nondurable goods) increased to 4.7% (), and it reached 8% in 2010 ().Similar growth can also be Metal-plated plastics (MPP), which are important from the standpoint of aesthetics or even performance, are increasingly employed in a wide variety of situations in the automotive industry. Serious environmental problems will be caused if they are not treated appropriately. Therefore, recycling of MPP is an important subject not only for Environmental Friendly Crush-Magnetic Separation Technology

Current industry position on plastic production and recycling
The plastics industry is thriving with employment reaching over 1.5 million people, with a turnover of €355 billion in 2017. According to the report by PlasticsEurope, the main market sector demand for converters that manufacture plastic products is in packaging at 39.7%. Table 6.1 shows the other sectors [ 2 ].Advances in technologies and systems for the collection, sorting and reprocessing of recyclable plastics are creating new opportunities for recycling, and with the combined actions of the public, industry and governments it may be possible to divert the majority of plastic waste from landfills to recycling over the next decades.Plastics recycling: challenges and opportunities PMC
