Used cooking oil – a problem and a smart solution

Sun, sandy beaches, crystal-clear water, scuba diving ... Bali brings to mind many associations. But the tourism paradise has a dark side: the way cooking oil is disposed of. And now a myclimate project is tackling it.


With about four million visitors a year, Bali is one of the world's most important and popular tourist destinations. And waste management is one of its most important problems, as it is in Indonesia. This is where the latest climate protection project from myclimate comes in.

Contributing to the waste problem is the way the island's hundreds of hotels and restaurants dispose of their used cooking oil. Used oil is either poured into canisters and thrown away together with the solid waste, dumped into the waste water, or sold on the black market, where it is more or less cleaned and reused in small kitchens. The current, non-sustainable method of disposing of used oil contaminates bodies of water, freshwater springs and soil, and contributes to global warming. Reusing the oil in private households, moreover, presents a health risk.

One of the key points of the climate protection project was to install equipment that converts this same used oil into biodiesel. The project has resulted in the setup of a local collection system for used, helped to organise a disposal service, created jobs for the local population and reduced CO₂ emissions by replacing fossil fuels with biodiesel from the project. Replacing fossil fuels in transport, electricity and heating reduces greenhouse gas emissions by 1,000 to 1,500 tonnes per year.

The project was initiated by Caritas Switzerland and represents a cooperative effort between Caritas, Kuoni Travel Ltd and myclimate.
