The 5 R's technique of waste management involves rethinking consumption habits, reducing waste, reusing items, recycling, and repairing items. Rethinking means finding ways to conserve resources by changing how products are used, such as using rags instead of paper towels. Reducing means buying items with less packaging in bulk and concentrated forms. Reusing means using items like reusable bags and refillable containers. Recycling means participating in community recycling programs and properly separating materials. Repairing prolongs the life of items and diverts waste.
