With the rapid rise in global population over the past decades there has been a corresponding surge in demand for resources such as food and energy As a consequence the rate of waste generation and resultant pollution levels have risen drastically Currently most organic solid wastes are either land applied or sent to landfills with the remaining fraction incinerated or anaerobically
