Looking back at the nuclear incident in Japan, looking for cleaner and more sustainable energy sources is of paramount importance. I have just visited an used cooking oil (UCO) to diesel recycling plant and is very impress with work and perseverance demonstrated by the founders.
The process is relatively simple; however the cost of production is not cheap. The process is as followed:-
1) Collect UCO from restaurant and households
2) Mix in a reacting tank with methanol and potassium hydroxide (KOH) at around 60 degrees Celsius.
3) Allow the glycerol (can be use to make soap) which is more dense to settle down and drain out.
4) Heat the remaining mixture to remove excess methanol
5) Filter the mixture(sawdust and resin) and the filtrate is allow to cool of again
6) End product - Diesel
No worries if the above seem quite complex. Participants who join the tour will be given a detail explanation on the whole process through video show, factory tour and lab-scale biodiesel
making demo.
This location is classified under both
factory and
educational category.
