The 4 Rs

Re-use

Recognising the continued usefulness of a product's function without considerable alternations and having an end-of-life product that can be used again for its original or close to original purpose. This could be as simple as reusing a plastic bottle or using a jam jar for storage.

Re-manufacturing

Re-assembling end-of-life products by means of replacing relevant parts for product reuse. A remanufactured product could be something that just needs a little repair work before it can be reused. Why throw the whole thing away if parts of it are still working?

Re-cycle

Re-engineering materials in their current form without splitting material to the original and most basic elements. Most people are familiar with recycled goods such as paper and glass, which are recycled to provide a fresh supply of the same product rather than using new resources.

Refine

Waste products are split to their original elements (bulk material form) for reprocessing into new/similar products. This is more flexible than recycling as it reduces the product back to its raw state allowing the user more choice in the creation of a new product.
