1Modern Methods of Solid Household Waste Management Almaty Waste Management Project – Principal Investment Parameters
2Project OverviewProject is constituted of the construction of the following facilities in Almaty: Plant for Mechanical and Biological Treatment (MBT) of Municipal Solid Waste (MSW), new Sanitary Landfill, and Waste Transfer Station (TS). Project is aimed to the improvement quality and reliability of waste removal services and compliance with environmental standards.Key principle of applied technology is MSW separation and recovery of recyclable and biodegradable fraction. The latter will be utilized for anaerobic digestion with production of biogas and further combustion of biogas for generation of green energy.The other Project objective is integrated development of MSW sector in Almaty including institutional reforms to make this sector commercially attractive and bring private investments into its development.

4General Principles of MSW management and Technical Concept for Project Implementation Maximizing of recyclables recovery from wasteMinimizing of biodegradable waste disposal at the landfillApplying feasible and efficient technologiesEnvironmental protection and improvementTariffs’ affordability for populationPhase implementation of MSW Management SystemCompliance with RoK legislation and Environmental ConceptCompliance with objectives of EU Directives related to environmental protection and sustainable developmentTechnical ConceptApplying waste sorting technologyAnaerobic digestionCompostingProduction of “green energy”Construction of sanitary landfill equipped with landfill gas collection systemClosure and rehabilitation of old landfills and dumping sitesUpgrade of waste collection system
5Preferable Option for Waste Treatment and Final Disposal New sanitary landfill in Iliyskiy DistrictTransfer Station (TS) and MBT Plant close to the city at the same site together with WWTPDelivery of whole MSW amount to the MBT Plant and TS located close to the city, integrated treatment of biodegradable fraction of MSW and WWTP sludge
6Scheme of location of WWTP and new landfill 1 – Site for planned allocation of new sanitary landfill2 – Area of Almaty Wastewater Treatment Plant (WWTP);3 – Boralday Village (the closest big settlement to WWTP);4 – Almaty city border (traffic junction between “Northern Ring” and Almaty-Kapshagai highways).

11Advantages of MBT Plant location close to the city and WWTP In case of construction of MBT Plant and TS at the same industrial site within 30 km from the city this option is preferable one since it provides annual cost saving in the amount 1.8 million USD (and even 2.6 million USD if these Facilities are located within 20 km from the city).In case of construction MBT Plant and TS close to WWTP additional advantages can be achieved. Utilization of biodegradable fractions from WWTP (mainly, the sludge) will significantly increase the generation capacity of green electricity. This will improve the economic and financial results of the Project implementation. In addition, this option will help to achieve rational land use since no additional land plots would be required for the drying and disposal of waste sludge from WWTP.
