1 Modern Methods of Solid Household Waste Management
Almaty Waste Management Project – Principal Investment Parameters

2 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.

3 Almaty MSW sector at a glance
Population people Percentage of population in multi-appartment houses 62 MSW from households (2011) ton MSW from commercial sector (2011) Total volume of MSW (2011) MSW from households, per capita (2011) 580 kg per pers. Total MSW per person per day (2011) 1.35 kg per pers. Per day Number of landfills 4* Number of waste collecting companies 49** Percentage of processing/sorting (of total MSW amount) 3 % Number of containers for separate collection of recyclables 400  Tariff for households (apartments) 300 KZT/pers./month Tariff for households (private houses) 341 Tariff for commercial sector 1 412 8 472 KZT per m3 KZT per ton 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%

4 General Principles of MSW management and Technical Concept for Project Implementation
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

5 Preferable Option for Waste Treatment and Final Disposal
New sanitary landfill in Iliyskiy District Transfer Station (TS) and MBT Plant close to the city at the same site together with WWTP 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

6 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).

7 Waste from other sources

8 Capital expenditures and utilization of investments according to the preferable Option
CAPEX item Amount, million USD Total investments (VAT exclusive) 179.7 Construction of the new sanitary landfill 27.8 Equipment and machinery for the landfill 2.6 Construction of MBT Plant 77.3 Equipment and machinery for MBT Plant 62.4 Construction of TS and vehicles for waste transportation 9.6

9 Operational and financial parameters of the preferable option
Unit Value (preferable option) Total MSW generation, Tons per year, average for the period 1,125,000 Total waste volume sorted at source, 130,000 Total waste volume directly disposed at the landfill, 495,000 Total MSW volume accepted for MBT Tons per year Percentage of recyclables recovery at MBT plant or other facilities, %, average for the period 6.0 Percentage of residues for disposal (after treatment) of total MSW volume, 80.0 Electricity production - capacity MW 8,6-12,0 Revenue from recyclables (2016) Million USD 4,4 Revenue from electricity (2016) 20,5 Operational & maintenance costs for the landfill (2016) 3.0 Operational & maintenance costs for MBT Plant (2016) 26,2

10 Tariff implications after implementation of the preferable option
Parameter  Value (preferable option) Tariff for the households, apartments, KZT per person per month (2016, nominal price) 617 Tariff for the households, private houses, KZT per person per month (2016, nominal price) 701 Tariff for commercial enterprises and organisations, KZT per ton (2016, nominal price) 17,400 Share of payments for MSW collection services in per capita income, households - apartments / households – private houses 1.29%/ 1.36% Perskaiciuoti

11 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.
