One process involving the recycling of plastics to make another kind of plastic product is the manufacture of railway ties, and structural building products. An innovative company today can manufacture these products from 100% recycled consumer and industrial plastics as well as plastic composites.
The benefit of railway ties manufactured from 100% recycled plastics and plastic composites is that these rail ties do not rust or rot. In addition, these ties do not crumble, splinter or absorb any moisture. Furthermore, they do not seep toxic chemicals into the ground surrounding the ties. Therefore, they are more environmentally-friendly in this regard.
Building materials created from recycled plastic are an alternative to wood, steel, as well as concrete for certain structural uses. One significant benefit of plastic structural materials as opposed to wood is that they are not subject to being infested by insects. Consequently, they will have a longer life in most cases.
Typically, sorted plastic is broken into small pieces. Next, these small pieces are washed. This washing removes glue, paper, dirt, and other elements that may have been incorporated into the original plastic product. In some recycling processes for plastic, the plastic pieces are melted and made into plastic pellets for further use. The recycled plastic can be used for an array of goods, just as the original plastic was used for products. However, recycled plastic cannot be used for the packaging of food.
