I recently asked a friend how I should recycle my used deep frying oil because I just don't have enough oil to justify taking my car, drive 20 minutes away to the waste collection site for few liters of oil.
So my friend advised me to just throw it within the garbage. The oil has to be burn anyway so it will be burned at the recycle station and generate electricity and heat from it.
One other solution, is to simply throw the oil in the sink. When it reaches the wastewater treatment plant, settling basins will separate the solid, the liquid and the floating oil.
So I propose here three solutions, and I would like to know which one is the most adapted for someone that want to eliminate about 5 liters used cooking oil per year.
Store it in the basement then go to the waste collection site located 20 minutes away by car and get rid of the oil once a Year.
Save that storing space by throwing 1 liter within the regular garbage 5 times a year in a sealed container.
Throw the used oil in the toilet and throw away the shrank empty plastic container in the prepaid garbage bags (I have to pay 3$ per 35l bag).
These propositions have to come with goals:
- Most energetically viable solution
- Less environment impact
- Most convenient solution
