the most common examples of primary recycling (reuse) are with glass containers, where milk and drinks bottles are returned to be cleaned and used again. reuse is not widely practiced in relation to plastic packaging - plastic products in general end to be discarded after first use. however, there are examples of reuse in the marketplace. for example, a number of detergent manufacturers market refill sachets for bottled washing liquids and fabric softeners. consumers can refill and hence reuse their plastic bottles at home.

· Primary recycling is taking the recycled material and putting it back into the same product; · secondary recycling is using the material in some other end product · tertiary recycling requires breaking the material down into its original components.

These policies typically come in three primary forms: recycling participation/source separation — This policy requires waste generators to source separate designated materials for collection and recycling. It is commonly referred to as “mandatory recycling.”
Primary recycling involves process scrap, or a single clean waste type. An important sub-class of primary recycling is known as "Closed loop recycling" in which polymer from a single product or product type is collected and recycled in-to the same product. Polypropylene from battery cases is a well established example.[5] Secondary recycling uses reclaimed post consumer materials as a source of material for new products. Tertiary recycling involves chemical breakdown of materials which are then re-utilised further back in the feedstock chain. Quaternary recycling is often termed energy from waste.
Two primary decomposers are fungi and bacteria. Their function in the recycling of life materials is very prominent because without them all organisms that died would decompose slowly.
The primary thing that makes modern recycling modern is its efficiency. Nearly every product made can readily be recycled to limit the effects on the environment.
One ViewPrimary recycling is also known as closed-loop recycling. In primary recycling, products are recycled into products of the same type, e.e.g aluminum cans to aluminum cans. In secondary recycling, products are converted into different products, e.g. tires into other rubber products. See Miller (2008, Living in the Environment, p. 527) for more information.Another ViewAccording to March, J et al, OCR Design & Technology for GCSE (2009, Hodder Education, Oxford) Primary Recycling is the reusing of a product - like giving an item to someone else (hand me downs), to a charity shop or washing out a plastic bottle then filling it up.Secondary Recycling is taking something apart and making it into something else - like making a pair of jeans into a bag. Tires into other rubber products.Tertiary or Chemical recycling is where products are broken down and re-formulated - eg plastic bottles into fleece fabric which can be used for coats or blankets.
