Cooking oils and fats

Products: e.g. frying fats, leftover salad oils, fondue oils; no mineral oils, no lubricating greases

Info: New technologies make it possible to process vegetable fats into high-quality biodiesel. Direct use as fuel is also possible.

Avoiding/reducing: Cooking oils and fats should never be poured down the sink, as this can cause blockages and pollute sewage treatment plants. Avoid unnecessary amounts of water or frying and roasting residues in fats and oils, as these substances prevent recycling.

Recycling/environmentally sound disposal: Cooking oils and fats are converted into biodiesel (fatty acid methyl ester FAME) at a processing plant. Contaminated fats and oils are sent to incinerators for energy recovery.
