In Thailand, there are 2 ways to handle the food wastes; to bury them and to make fertilizer form them. In making fertilizer, the wastes are piled up. EM will then be poured over them before the pile is covered and left to decompose. This method requires a lot of area, water and oxygen to help decompose. It also causes a lot of Carbon Dioxide. The piles are also great places for germs, and pest to grow. In Burying the wastes, it requires quite large area to do it. Both ways of handling food wastes are not good for the environment.
How does the liquid food waste decompose?
After the food wastes have been mashed by the food waste disposer, they become colloid solution.
The solution is then sent to the grease trap and wasted water treatment system.
The large pieces of wastes :
Bacteria requires a lot of time to decompose them.
It is hard because the decomposition has to
start from the outer skin inward.
The tiny pieces of wastes :
Bacteria can decompose them rapidly
because the decomposition can be done
in multiple direction.
Once the organic matters pass through the grease trap, they will not cause pollution to the water since they are too small to clog.
The matters can flow freely with the water and they don’t cover the surface of the water like grease.
As a result, the oxygen can dissolve in the water and the natural bacteria can then decompose them rapidly.
