Analysis of plastic packaging recycling in the United States
the United States is a major plastic producer in the world, As early as last century) (extensive research on the recycling of waste plastics has been carried out since the s, and regulations restricting the use and discarding of plastic products have been formulated from local departments, counties to states.
in 1988, Florida will teach the plastic model selection of tensile testing machines. According to the regulations, hard packaging containers within a certain specification range must pay ADF, that is, promote the waste plastic treatment fee. In 1993, it was revised to use containers with 0% waste plastics or recycle 2 in this state Manufacturers of 5% plastic containers can be exempted from ADF
in 1989, New York state banned the use of non biodegradable vegetable bags, gave subsidies to manufacturers of degradable plastics, and required people to separate renewable and non renewable waste, otherwise they would be fined $500
California's 1991 law requires that the recycling rate of waste plastics reach./by 1995, Or make all containers contain 25% waste plastic, reduce 25% raw materials, and gather and develop trading enterprises in the city for reuse for 5 times; In 1995, it was stipulated that 30% recycled plastic should be used in garbage bags
the federal government took the lead in restricting and banning some plastic products in 1988, and then cancelled some prohibition orders. Instead, it formulated the "resource protection and recycling measures" to regulate the treatment of solid waste, specifically stipulating that the recovery rate of plastic products is 65%, and the recycling proportion of 65% of the recycled products must reach 45%
many national organizations are promoting the recycling of waste plastics. For example, the American Plastics Industry Association (SPI), the plastic recycling Foundation (pre), the plastic recycling Research Center (cprr), the vinyl Research Society (a branch of SPI), etc. In order to facilitate classification, SPI has formulated plastic product material symbols, which are required to be marked on the bottom of the container respectively. At present, 39 states are implementing the law. In addition, some large plastic production companies in the United States also participate in the recycling of waste plastics, such as Amoco, mobile, polisa, herzman, Al detection and control are two different concepts. Eight of the largest PS manufacturers, including Amoco, Chevron and dofena, have established PS recycling centers with a total investment of US $16million to recycle foamed PS, and the recycled plastics are used to manufacture tape boxes, offices and household appliances
