Success Story of Biogas CNG Plant at Kodoli Kolhapur
Highlights:– Developed on a BOOT (Build, Own, Operate and Transfer) basis– Daily capacity of approximately 100 tons, or 35,000 annual tons, of sugarcane
waste (pressmud)– Daily production of approximately 7,000 to 9,000 kg’s of Bio-CNG per day– PESO (Petroleum and Explosives Safety Organization) License for storage and
filing of Bio-CNG in high pressure cylinders– Daily production of organic manure/soil conditioner after further processing
for commercial sale– NOCA (National Organic Certification Association) approved organic manure
for further sale to farmers– MNRE (Ministry of New and Renewable Energy) approved investment subsidy
received in early 2013– Substantial cost savings for industrial customers due to low-cost Bio-CNG use– Climate friendly – CO2 negative: Biogas-to-CNG conversation is the most
productive use of agricultural waste
In partnership with India’s largest sugar producer, Bajaj Hindustan Limited, SREL
will convert approximately 30,000 to 50,000 tons of pressmud annually into
renewable energy and organic manure/soil conditioner. Construction is expected
to start in late-2014.

WARM MODEL: USEPA Tool for CO2 Reduction Estimation
http://epa.gov/epawaste/conserve/tools/warm/index.html
EPA created the Waste Reduction Model (WARM) to help solid waste planners and
organizations track and voluntarily report greenhouse gas (GHG) emissions reductions
from several different waste management practices. WARM is available both as a
Web-based calculator and as a Microsoft Excel spreadsheet (.zip) (586 Kb). The Excel-
based version of WARM offers more functionality than the Web-based calculator.
WARM calculates and totals GHG emissions of baseline and alternative waste
management practices—source reduction, recycling, combustion, composting, and
landfilling. The model calculates emissions in metric tons of carbon equivalent (MTCE),
metric tons of carbon dioxide equivalent (MTCO2E), and energy units (million BTU)
across a wide range of material types commonly found in municipal solid waste
(MSW).

Waste to Energy Recovery through Cogeneration
Benefits of Cogeneration
•Increased efficiency of
energy conversion and use
•Lower emissions, especially
CO2
•Ability to use waste materials
•Large cost savings
•Opportunity to decentralize
the electricity generation
•Promoting liberalization in
energy markets
A Cogeneration system or a Combined Heat & Power System (CHP) is the sequential or
simultaneous generation of multiple forms of useful energy. It is usually mechanical
(power) and thermal (heat) in a single, integrated system.
Efficiency Advantage of Cogeneration
•When both thermal and electrical processes, a CHP system typically requires only three-fourth of
the primary energy compared to separate heat and power systems.
•This reduced primary fuel consumption is key to the environmental benefits of CHP as burning the
same amount of fuel more efficiently means fewer emissions for the same level of output.

Types of Cogeneration Systems
Steam Turbine Cogeneration System
• Widely used in CHP applications
• Oldest prime mover technology
• Capacities: 50 kW to hundreds of MWs
• Thermodynamic cycle is the “Rankin cycle”
that uses a boiler
• Most common types
• Back pressure steam turbine
• Extraction condensing steam turbine
Gas Turbine Cogeneration System
• Operate on thermodynamic “Brayton cycle”
• atmospheric air compressed, heated,
expanded
• excess power used to produce power
• Natural gas is most common fuel
• 1MW to 100 MW range
• Rapid developments in recent years
• Two types: open and closed cycle
Reciprocating Engine
Cogeneration Systems
• Many advantages: operation, efficiency,
fuel costs
• Used as direct mechanical drives
• Four sources of usable waste heat
Topping Cycle
• Supplied fuel first produces power
followed by thermal energy
• Thermal energy is a by product
used for process heat or other
• Most popular method of
cogeneration
Bottoming Cycle
• Primary fuel produces high temperature
thermal energy
• Rejected heat is used to generate power
• Suitable for manufacturing processes
Energy Generation from Industrial waste through Gasification
Gasification is a process that converts organic or fossil fuel based carbonaceous materials into
carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high
temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam.
The resulting gas mixture is called syngas (from synthesis gas or synthetic gas) or producer gas and
is itself a fuel. The power derived from gasification and combustion of the resultant gas is
considered to be a source of renewable energy if the gasified compounds were obtained from
biomass
Cogeneration in Maharashtra
� In Maharashtra, there are more than 202 sugar mills, showing large scope for implementation of WTE through cogeneration.
� Consumption of Bagasse in Sugar industries by use of use of high pressure boilers (above 60 bars) reduce Bagasse consumption and make power projects highly profitable.
� Present installed capacity of cogeneration based power generation is 300 MW.
� Additional target of 1000 MW has been considered in new policy declared by GoM on 30-08-2014.
� The Maharashtra Electricity Regulatory Commission (MERC) has been declaring attractive tariff for cogeneration power projects from time to time.
� This has resulted in having 33 cogeneration power projects totalling 480 MW commissioned in Cooperative sector and approximately 10 Cogeneration power projects totalling 191.5 MW in private sector in the state.
� The prevailing regulated tariff declared by the commission on 07th Jul, 2014 for Cogeneration projects is Rs. 6.27 per unit for the year 14-15.

� The Indian Renewable Energy Development Agency has been established under
the Ministry for Non-Conventional Energy Sources as a specialized financing
agency to promote and finance renewable energy projects.
� Reserve Bank of India (‘RBI’) has relaxed the External Commercial Borrowings
(‘ECB’) norms by expanding the definition of infrastructure to cover sector such
as Energy which in turn covers sub-sectors such as Electricity
generation/transmission/distribution.
� With a view to strengthen the flow of resources to infrastructure sector, RBI has
also now permitted raising ECB for project use in SPVs in the infrastructure sector
under the automatic route/approval route, as the case may be.
� Undertakings engaged in the generation and/or distribution of power has been
offered a 10-year tax holiday for renewable energy plants if power generation
begins before 31 March 2014. However, the plants have to pay a minimum
alternative tax at the rate of approximately 20 to 21 percent (based on the
income), which can be offset in future years (10 years).

Future of Waste to Energy Projects from Industrial Waste in India
� The present appetite of Indian Industry, duly supported by Government linked
incentives, coupled by strong environmental compliance promise brighter future for
upcoming planned and under commissioning projects in India for waste to energy
from industrial waste.
� The presence of best available technology and access to latest technology in India by
leading world companies has also induced sense of excitement in the industry, as
every technology developer and supplier tends to create his niche in market.
� Recent commitment made by India to curb its GHG emissions is a big driving factor,
which would provide sufficient financial and techno-commercial support to industry
to undertake more projects.
� Revision of green laws and insistence on CEMS by legal enforcement agencies would
also result in undertaking of waste to energy recovery options by industries.
� Sustainability initiatives made by industry would also act as a key factor to drive
more waste to energy recovery options from industrial waste in India
