Recycling
Recycling, recovery and use of waste material. Paper, aluminum cans, and glass are the most commonly recycled materials and can be used to make insulation, new cans and glass containers, and material for road construction. As concern over the earth's environment increases, recycling has emerged as an effective method for cutting down on pollution and conserving important natural resources. It has also become an increasingly vital source of material for modern industry.
