Recycle. Recycling converts used items back into raw materials which are then used in making new products. "Recycle" comes third after "Reduce" and "Reuse " because recycling requires new resources for transportation and the manufacturing process. Nevertheless the economic and environmental benefits are significant.
Carbon nanotubes from post-consumer waste plastics
1. Introduction. There is increasing worldwide concern in relation to the impact of the large tonnages of waste plastic on the environment 1 2 .In response there has been a marked rise in the collection and recycling of waste plastics for example in Europe in 2018 29.1 million tonnes of waste plastics were collected with 32.5 recycled 42.6 used for energy recovery (mainly incineration
Electrostatic Separationan overview ScienceDirect Topics
Dry sorting processes apply mechanical (sieves) or electrostatic forces or they sort by means of spectroscopic detection systems. Sieves or air classifiers are applied to reduce the amount of fine particles in waste plastic fractions since the fines contain small metal particles from grinding processes and dust collected on plastic surfaces in the use or reclamation phase.

Although the benefits have not been quantified plastics recycling also offers the potential to generate demonstrable savings in fossil fuel consumption both because the recycled plastics can supplement and even compete with ‘’ resins produced from refined fossil fuel and because the energy required to yield recycled plastics may be less than that consumed in the production of the same resins from feedstocks . Therefore plastics waste recycling

RECYCLING METALS FOR THE ENVIRONMENT Annual
The first stage in the recycling of metal is its separation from other materials. The difficulty of separation increases with lower concentrations of metal in the source. Pieces of an individual metal (e.g. copper wires in cables) are easiest to recycle while metals thinly distributed in products (e.g. copper in printed circuit boards) require
