Recycle
Recycling is the process of making or manufacturing new products from a product that has originally served its purpose. If these used products are disposed of in an appropriate, environmentally friendly way, the process of recycling has been set in motion.
Reduce
It means reducing your consumption or buying less. Designing items like plastic bottles in ways that use less material is another way to reduce consumption.
Reuse
Reuse is to use an item again after it has been used. This includes conventional reuse where the item is used again for the same function, and new-life reuse where it is used for a different function.
Refuse/Reject
The awareness to decline goods which one deems environmentally harmful such as non-biodegradable items.
Repair/Reform
The recovery of an item to its initial function and maintenance of product shelf-life.
