In this world.....when we are celebrating days like International Environment Day or The Earth Hour to spread awareness around the world about the Global Warming, we need some major steps to save our environment. When, i was in school we were always thought about the three R's "Reduce, Reuse and Recycle".
Now, a days a lot of technologies are being invented, discovered and reinvented to save the environment. There is one new one which i have heard around a lot. N-Viro is an International Corporation which develops technologies so that the wastage produced daily can be reduced plus reused. Their patent process use mineral rich combustion byproducts to treat, pasteurize, immobilize and convert waste water sludge and other bio-organic wastes into bio mineral agricultural and soil-enrichment products with real market value.
This is something really new which i have heard of. It promotes reusing of waste water sludge....i think it's not even reuse ....it's something we have ignored till now......but they are using it as a bio chemical waste and using it to make new soil enrichment products.
