Dubai: Restaurants in Dubai have been given guidelines for the disposal of fats, oils and grease by the Department of Drainage and Irrigation in Dubai Municipality.
They are required to install grease traps or interceptors to separate waste and to clean them on a regular basis to comply with public health regulations.
If edible oil is tipped down the sink, it can contaminate the water supply. It is thought that one litre of oil can contaminate one million litres of water.
Oil is lighter than water and so can coagulate on the inside of pipes, proving hazardous for kitchen environments and sewage treatment plants (STPs).
The grease and waste will be disposed of at the Dubai Municipality-Alserkal Envirol Recycling Plant in Al Aweer, which was established in 2008.
Statistics on the amount of waste collected and disposed of is recorded.
The recycled waste can be used to make soap, candles, paint and other materials such as polymers and biofuels, for example.
Water is used for irrigation and any other solid organic waste is transformed into fertiliser.
