Egypt: Cairo Southern Zone Composting
(Carbon Fund for Europe)
UNFCCC Reference No.:
The Egyptian Company for Solid Waste Recycling (ECARU) has a 10-year contract for the processing and land filling of municipal solid waste from the Cairo Southern Zone. The owner of the facility is Cairo Cleaning and Beautification Authority (CCBA), Governorate of Cairo.
The project involves the development of a treatment, recycling and disposal facility for the purpose of processing solid waste that is collected and received on a daily basis from the Southern Zone of Cairo. Waste received includes municipal solid waste, construction and demolition waste and non hazardous industrial waste. Processes conducted in the treatment facility involve the following:
- Land filling
The total amount of daily waste that on the basis of a delivery schedule of 300 days per year could be handled by the ECARU treatment and disposal facilities is:
- 1500 ton/day of domestic waste
- 500 ton/day of demolition waste
However instead of receiving 1500 tonnes, at the moment on average only 374 tonnes of municipal solid waste per day are currently delivered to the composting facility. Based on data for 2007 from the ECARU administration, provided by Mrs Dalia Essmat of ENTAG/ECARU on August 24, 2007 The demolition waste contains limited organic matter and is directly transferred to the landfill.
The composting process consists of two phases. In both phases the waste is set-up in a windrow:
- A fermentation phase which lasts 28 days and during which twice a week a turning machine turns the waste. The turning keeps the process aerobic. Moisture is added to regulate the process.
- A maturation phase that lasts 45 days, during which the windrows are turned on average once per week, depending on feedback from process control.
According to the contract signed with the CCBA the composting process should last 73 days.
Under the contract with the CCBA ECARU has the right to sell all products generated from the services provided under the contract including: the compost, the recyclables and the emission reductions. Letter of CCBA to ECARU of 9 January 2007
Most of the compost produced is sold to farmers (about 82% percent).
