Plastic RecyclingRecycling is the process of collecting, sorting, cleaning, treating and reconstituting materials that would otherwise become solid waste, and returning them to the economic mainstream in the form of raw material for new products. Plastic recycling is the process of recovering scrap or waste plastics and reprocessing the material into useful products, sometimes completely different from their original state. For instance, this could mean melting down soft drink bottles then making model army figures and ammunition.Recycling Plastic Makes Economic and Environmental Sense-- The greatest challenge to recycling manufacturers is educating and engaging the public. About 75 percent of Americans recycle newspaper and cardboard while little more than 25 percent recycle plastic. Industry analysts think this low response rate might be due to a lack of understanding about the coding on recyclable plastics - the small triangle with a number in the center - that identifies what kind of plastic an item is. The most frequently recycled plastics... more Related Websites
Recycling Plastics-- Due to the growing need for plastic bags and containers in places such as grocery stores and retail stores, plastic is now one of the most used materials in today's society. When it comes to an increase in soil and water pollution, plastic waste is the largest contributor. While recycling may seem like an easy task to most it is not recycled nearly as much as it should. Plastic recycling is the act of parting... more Related Websites
Molding our World: Plastics as Part of our Daily Lives-- Plastics as we broadly understand it today are synthetic or semi synthetic products or raw materials, formed by polymerisation, and are largely derived from oil. Polymerisation is the formation of polymers i.e. repeated numbers of smaller structures (monomers) joined together. It wasn't until the 1860s that the first semi synthetic materials or plastics were first brought to the attention of the world, and since the development of thermoplastics throughout the 1900s it's hard to imagine... more Related Websites
Recycling Plastic Bags-- Some companies place recycling bins for plastic bags at their stores. When customers come back to the store they can bring their bags and recycle them easily. However, the number of bags leaving the store and the number returning are not quite equal with far more going out then coming back. Some stores are getting rid of the bags all together. The stores have started to encourage the use of cloth shopping bags and some... more Plastic Recycling-- When compared to other materials like glass and metal materials, plastic polymers require greater processing to be recycled. Plastics have a low entropy of mixing, which is due to the high molecular weight of their large polymer chains. A macromolecule interacts with its environment along its entire length, so its enthalpy of mixing is large compared to that of an organic molecule with a similar structure. Heating alone is not enough to dissolve such a... more |
