From 1980 to 2007, the amount of municipal waste from around the globe has increased from 415 kg to 560 kg.
Most of this waste ends up in landfills.
Landfilling waste can lead to soil erosion, water pollution, and the depletion of the ozone layer. Hence, landfilling negatively affects the health of the environment.
To reduce this negative effect waste has on the environment, many techniques like incineration, anaerobic digestion, biodegradation, liquefaction, pyrolysis, and many more have been implemented to convert waste to an energy source.
This energy source comes in the form of biofuels and is usually in the liquid or gas phase. Biofuels are a mixture of fatty acids from animal fat.
In 2006, the main technique used to convert biomass to biofuels is by fast pyrolysis. It was discovered that during pyrolysis, low temperatures will produce the maximum amount of liquid product while a high temperature will produce the maximum amount of gas product.
However, as technology advances, different forms of conversion can be used like liquefaction, catalytic oxidation, and biological degradation.
Liquefaction allows the biomass to have high...
