Unsustainable waste management  brings about huge financial loss,   environmental and health damages  with the uncontrolled emission of greenhouse gas such as methane CH4 into the atmosphere .

“Waste " is everything that no longer has a  value, use  or purpose and needs to be disposed  of.  The above definition considers Waste (a  natural consequence of human  activities)  as  a burden in our  society.   H owever , with the shift in attitude and a better understanding of global warming, sustainable consumption, waste is no longer valueless, but priceless asset. How is this so?

Bees need two different kinds of  food- one  from nectar, the sugary juice that collects in the heart of the  flowers; the  other are numerous  small grains called  pollen collected from  the  anthers of  flowers  Eventually, the  “  W aste” product of the Bee is what humans lick as honey. Ideally, nothing is wasted in nature; it is unsustainable human practices that create waste.
