Food Waste Treatment and Pelleting
Current Problem
Solid Waste (SW) collection in urban centers of developing nations is a major challenge. In most of these nations the generation of SW surpasses the collection. The same is true in Addis Ababa, Ethiopia, where close to 75% of SW is generated in households, and close to 50% of the generated SW is not collected due to poor collection system.
Currently in Addis Ababa, primary collection (from households, hotels, hospitals, commercial areas, street sweepers and industry) is conducted by pre-collector associations, secondary and the final disposal is carried out by the government, and some small and micro/medium enterprises (SMEs). The primary reason for the inefficient collection of SW in Addis Ababa is due to various factors such as lack of entities engaged in primary collection, not having enough trucks that transport SW from secondary collection centers to disposal site (Rappi landfill). Although the Addis Ababa Municipality has engaged many SMEs, and private vehicles, there isn’t enough capacity between the Municipality and the private sector to collected all of the SW that’s generated in the city.
