There is no simple solution to the waste management problem. Therefore, companies often seek a solution in a combination of measures that produce a synergetic effect. Reducing the quantity of inputs, reusing manufacturing by-products, burning waste to recover the energy and recycling are parts of the solution. Companies sometimes focus only on the first 3Rs in resolving waste management problems. If waste is produced, every effort should be made to reuse it if at all practical.
Recycling is the third option in the waste management hierarchy.
Although recycling does help to conserve resources and reduce wastes, it is important to remember that there are economic and environmental costs associated with waste collection and recycling processes. For this reason, recycling should really only be considered for waste which cannot be reduced or reused. Empirical evidence suggests that by practicing waste prevention, reusing products, recycling and making environmentally conscious purchases, business can cut costs and increase profits.
