2. Pune City- A Brief Profile on SWM
Sixth largest city in India
Total Area Sq. km.
Current Population Lakhs
Total Waste Generated MTD
MSW Generation Gms./capita/day per day
Organic Waste Content 45-50% - Waste-to-Energy

3. Why Decentralized Biomethanation Plants…?
Open Dumping was stopped during – PMC had no option but to explore alternatives for processing & disposal of MSW.
Organic MSW is putrescible in nature and need immediate treatment to avoid any adverse implications on human being & environment.
Basic Philosophy behind setting up Decentralised Biomethanation plant is To Treat & Dispose off Segregated Organic Wet Wastes in a decentralized manner.
Reduction in transportation Rs per ton of waste, approximately Rs lakhs annually.
Increase effective life of Sanitary Landfill.

The total CO2 equivalent emissions could have been 5.58 times the current emissions in case PMC had not installed the scientific technologies to process MSW in Pune city

8. Structure of PMC’s Biogas Program
PMC’s Obligations
Providing Segregated Organic Wastes at site
Providing Land, Water & Electricity at Free of Cost during O&M
Taking away rejects form the plant area on day to day basis
Manure Lifting & Utilization Mechanism
Connecting Liquid Manure to the Drainage – STP
Obtaining necessary Statuary Clearances - MPCB
Electricity distribution arrangement

9. Structure of PMC’s Biogas Program
Obligations of Technology Supplier – EPC Contracting
Design, Supply, Installation & Testing & Commissioning.
Carrying out post commissioning O&M for 5 years.
Ensure periodical checks of all safety aspects of the plant
Ensure smooth & continuous O&M on long run basis.
Prompt response to maintenance issues to avoid shutdowns

Structure of PMC’s Biogas Program
Domestic Scale – Privately Owned - Bungalow’s /Flats / Housing Complexes / Hotels / Institutes/ Resorts./ Residential Colonies. (100 Kg. to 3 TPD)
Medium Scale (Decentralized) - Owned by PMC (5 – 10 TPD)
2.1 PPP Mode – ULB’s (Capital Cost + O&M) + Institutes (Land) = Institutes may utilize biogas for cooking / Electricity generation.
2.2 PPP Mode – ULB’s (Land + O&M Cost) + Rotary Clubs / Industrial Houses (CSR) (Capital Cost) = ULB’s may utilize biogas for cooking / Electricity generation.
Large Scale (Centralized System) - DBOOT / BOO .( TPD)

Areas of Concern
Approach – Waste-to-Energy is an Integral part of SWM – can not be implemented in isolation.
Awareness - Limited knowledge about Biomethanation
Not a priority area – always neglected while budgeting
Prerequisite Requirements - Segregation of Wet wastes at source and separate transportation facility for segregated wet wastes.
Securing funds for O&M on annual basis.
‘Economics ‘ overpower ‘Necessity’
Economics depends on effective utilization of by-products.
Treatment of leachate is always an issue for debate – No concrete guidelines

17. Some Suggestions
Registration of Technology Providers with SNA/MNRE is must – to keep the hold on Technology Suppliers.
CFA conditions should be user friendly and based on the practical outputs / results rather than academic figures.
There must be a common ‘Scope-of-Work’ to be defined, to bring project cost competitive & bring Technology Suppliers at common platform.
Since, ‘Waste-to-Energy’ offers duel benefit – Renewable Energy Generation and Pollution Abetment – Tax (5% VAT) exemptions will help to bring down the costs as well as to reach maximum clients.
Allow Thermal application eligible for subsidy
Since it is Green Energy Projects - SPCB’s approval may be waved off.
