Modern Methods of Solid Household Waste Management Almaty Waste Management Project – Principal Investment Parameters
Project Overview • Project 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.
Almaty MSW sector at a glance • 49 private waste collection companies • Operating main landfill in Karasaiskiy District • Waste collection rate is close to 100% • MSW recycling/treatment rate is only 3% • 97%of total collected MSW is delivered to over-filled landfill • Non-operating waste sorting plant (“Vtorma Ecology Co”) * 80% of MSW are transported to the main landfill in Karasaiskiy District ** Market share of principal MSW collection company (“Tartyp” LLP) is 70%
General Principles of MSW management and Technical Concept for Project Implementation General Principles • Maximizing of recyclables recovery from waste • Minimizing of biodegradable waste disposal at the landfill • Applying feasible and efficient technologies • Environmental protection and improvement • Tariffs’ affordability for population • Phase implementation of MSW Management System • Compliance with RoK legislation and Environmental Concept • Compliance with objectives of EU Directives related to environmental protection and sustainable development • Technical Concept • Applying waste sorting technology • Anaerobic digestion • Composting • Production of “green energy” • Construction of sanitary landfill equipped with landfill gas collection system • Closure and rehabilitation of old landfills and dumping sites • Upgrade of waste collection system
Preferable Option for Waste Treatment and Final Disposal • Delivery 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
Scheme of location of WWTP and new landfill • 1 – Site for planned allocation of new sanitary landfill • 2 – 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).

Advantages 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.
