Plastic 4R concept (Reduce,Reuse,Recycle,Recovery) (4R)
(1) Reduction
(2) Reuse
(3) Recycle
(4) Recovery
(1) Reduction
- Minimizing the consumption of raw material true improvement in the design the products may allow a significant reduction in the design of products and in the amount of waste generated when the reached through end of the life cycle.
- Decreasing in the weight food container cab be seen in the last 20 years but there is a limit to the which can be made by weight reduction in the mechanical properties and performance of the products are also affected by the decrease.
(2) Reuse
- This is mainly applied to packaging goods been defined as anyoperation by which the packaging items are refilled or used for the same purpose for which they were made with or without the support of auxiliary products.
- Consumer and industries encourage to promote the reuse of Goods and packaging instead of disposal.
- This option can be applied for container such as bottles,bags,etc.
(3) Recycle
- This allows the waste to be reintroduced intothe consumption cycle Generally and secondary applications because in many cases the recycle products of lower quality then the virgin ones. The recycling must be applied only when the amount of energy consumed in the recycling process is lower than the energy required for the production of new materials. plastics can be recycled by using two different approaches Mechanical Recycling, Feedstock recycling.
- In the first case plastics are recycled as polymers whereas in the second case Plastic waste are transformed into Chemical or fuels.
(4) Recovery
- When the recycling of waste is not feasable or there is no market for the recycle product incernation can be used to generate energy from the waste combution heat.
- Plastics materials of high calorific value in the Plastic waste greatly contribute to the energy produce in the incarnation plant.
- Alternatively they can be used as fuel in number of applications like powerplants, Industrial furnaces and cement industries.
