BACKGROUNDFour major companies provide catering services across the UN complex in Gigiri, Nairobi, Kenya. These catering services include preparing and serving food to staff, visitors, and participants in key conferences and meetings.The caterers operate in kitchens and utilize wastewater disposal infrastructure provided by the UN. The UN monitors catering activities to ensure optimal use of these facilities.CURRENT SITUATIONSignificant quantities of cooking oil are used in food preparation. These oils are typically discharged into the wastewater system along with dishwashing water. To separate grease and oil, the larger kitchens are equipped with grease traps, devices that retain floating substances such as fats and oils. These substances accumulate in the traps and can be removed using a vacuum truck.In Nairobi, wastewater (including fats and oils) is commonly collected from various locations using vacuum trucks and transported to Dandora, where it is discharged into wastewater treatment ponds.This practice is unsustainable, as the anaerobic treatment process in the ponds results in greenhouse gas emissions that are approximately 21 times more potent than carbon dioxide (CO₂).However, fats and oils can be relatively easily converted into biogas or biodiesel, a significantly more sustainable solution. In this process, fats are transformed and reused as fuel, producing primarily CO₂, which has a much lower environmental impact.This method is already standard practice for rela...
