Some of the products used in our modern society are too toxic to be disposed of without particular treatment. Not only the industry generates such kind of poisonous and hazardous waste but also many household products fall under this category. If not disposed of correctly, some cleaners, solvents, pesticides, paints, etc. can contaminate a landfill, leak into the ground water or contaminate the ocean resulting in tremendous risks for the safety and health of human beings. For the respect of our environment, the basic 3Râ„¢s rule (reduce, re ....etc

Recycle means to recover useful materials from garbage or waste or it can also be defined as to extract and reuse. While recycling is a term generally applied to aluminium cans, glass bottles & newspaper, water can be recycled as well. Nature reuses & recycles its resources without creating toxic dumps or polluted waterways. By imitating nature we can learn to recycle our wastewater relatively inexpensively, with minimal distribution cost &the bonus of reclaimed resources. Scientists are now recognizing the simplicity and effectiveness of natur ....etc
