The 3Rs stand for Reduce, Reuse and Recycle. They are in the order of importance.
Reduce is the first and most important “R” in the 3R hierarchy and has the greatest positive impact on the environment. Reducing waste requires us to rethink our daily habits to avoid making waste in the first place.
Reuse is the second most important “R.” Reuse is any activity that lengthens the life of an item. Reusing requires us to consider how items could be reused at the time of purchase or look for ways items can be reused before they become destined for the landfill.
Recycle comes last in the 3R hierarchy but is still very important. Recycling is the reprocessing of an item into a new raw material. When we recycle, we give waste materials new life while saving energy, water and natural resources.
