Pitch

Energy Security in 21st Century needs Hybrid model with; Top-down and bottom-up approach to meet environmental and economic Sustainability.


Description

Summary

The Integrated Energy Production & Waste Treatment Project (IEP&WT) - FOR BIOGAS BUSS PROJECT is a study based project proposal to highlight the potential of converting cattle dung and vegetable waste produced in Ghazipur catchment area into renewable energy.

Biogas based Waste-to-energy (WTE) plants are systems that use a bacteriological process called anaerobic digestion to convert organic waste into biogas.

 

Different economic activities in dairy complex and vegetable & flower market of Ghazipur catchment area, Delhi (India) is producing approx. 147807kg of dung waste from about 13,437 dairy cattle and approx. 8700kg of vegetable & flower waste on daily basis. The organic wastes from both the units (dairy complex & vegetable market) are broken down by bacterial action in a series of stages that result in the formation of CH4(methane) and CO2. The Global warming Potential (GWP) of methane (CH4) is 72 over a 20 years period or in other words methane is 72 times stronger than CO2.

Biogas as a source of renewable energy has made three fold contribution in climate protection:

  • Preventing the discharge of CH4 in the atmosphere;
  • Replacing fossil fuel with clean fuel sources;
  • Replacing Chemical Fertilizer by proving manure to Horticulture department of municipal corporation

Technological sustainability:

  • Disseminating technological knowledge and know-how by introducing state-of-the-art technology adapted to local circumstances;
  • Promoting technology transfer and encouraging further project development by demonstrating the feasibility of such a bioCNG based WTE plant in India.

 

The energy potential of readily available organic material in Ghazipur Dairy Cluster and Vegetable market is estimated at 393105kg (at 75% of PLF) of bio-CNG equivalent to 519645ltr of diesel or 528606 kg of coal per year.

The proposed project is a considerable example of centralized anaerobic co-digestion plant of Sustainability for BIOGAS BUS PROJECT.


Category of the action

Reducing emissions from waste management


What actions do you propose?

      A. GENERAL INFORMATION OF PROPOSED BioCNG BASED Waste-to-Energy PLANT IN GHAZIPUR DAIRY COMPLEX

Project Activity: In the Ghazipur Dairy cluster the project proponent intends to build 3116 cubic meter Biogas & fertilizer plant as a part of the proposed Greenfield project activity. Through this project activity the amount of greenhouse gases emitted into the atmosphere will be reduced.

Pre-Project Scenario: In the pre-project scenario, about 85-90% of dung produced on daily basis from Ghazipur dairy (dairy cows & dairy buffalos) are washout into open drain and remaining 10-15% will be used for preparing dung-cakes (upale) or wasted in open drying yard where it is allowed to further degrade.

Organic waste generated from Ghazipur vegetable & flower market has no sustainable solution. As per primary study about 8000 kg (i.e. 7000 kg from vegetable & fruit market and 1000kg from flower market) organic waste is generated from these markets are transported to Ghazipur landfill site where it further degrade and contributes in emission of CH4 in local and global environment. Both these source release CH4 (methane) into the atmosphere, unless treated in waste-to-energy plants such as proposed project activity.

Post-Project Scenario: In the post-project scenario, the project proponent procures dung from approximately 347 operational dairies and vegetable & flower waste from Ghazipur vegetable & flower market. The dung and vegetable & flower waste will be collected on daily basis and will be delivered to a substrate storage area at site and is off-loaded onto a scraper floor for continuous feeding into stirred digesters. Under controlled conditions biogas is produced through bio-methanation process, which recovers the methane (biogas) from the litter. The biogas which is further converted into BioCNG/CBG by removing carbon dioxide, Hydrogen Sulfide, moisture can be compressed into cylinders and make it easily available for transportation and stationary application in nearby Eastern Delhi market. Today CNG technology has became easily available for waste-to-energy projects, bio-menthe (enriched biogas) which is nearly the same as CNG, can be used for all applications for which CNG are used.

6. Process Flow and its Description

PROCESS FLOW:

                                                 Fig.4. Process Flow

PROCESS DESCRIPTION:

6.1. Waste Handling & Slurry Preparation Section (Vegetable Market Waste):

a. Receiving Area: The waste collected from the vegetable market is brought to the existing transfer station where packing material and silts are removed. The waste free from plastics, cloth, stones, slit and other impurities is transferred to the receiving area and collected at the receiving platform.

b. Waste Handling: On the receiving platform, a mechanical handling system namely “Grab” with traveling electric hoist is provided to handle the received waste and the walkway is provided for the person to handle the Grab. The waste is transferred by the Grab to the feeding hopper of the conveyor and transferred through the conveyor for size reduction.

c. Waste Segregation: The waste being carried through the conveyor is sorted by persons standing on the supporting platforms parallel to the conveyor. Substances such as plastics, clothes, wood, stones, which are not biodegradable, are removed.

d. Ferrous Separation: Magnetic separator is provided parallel to the conveyor so that the iron (ferrous) materials, if any, which would get stuck to the magnetic separator and the iron materials are removed manually and stored in the bins for sale/Disposal.

e. Size Reduction: The waste will be delivered into the Shredder to reduce the wastes to uniform size of around 15 - 20 mm. Shredder has knives which cuts the wastes into small particles. The shredder can process about 4 tones /h. After size reduction wastes will be transferred into a tank.

6.2. Ghazipur Dairy Waste (Cattle & Buffalo waste):

The cattle and Buffalo dung will be collected from approx. 347 operational dairies on daily basis through tractors and brought near the loading dock on to the ramp and the dung waste is unloaded. The animal dung is blended in a collection tank.

6.3. Dissolution (Homogenization of Raw Manure):

The animal dung and shredded vegetable waste is blended in a collection tank/ Feed tank to provide a waste of uniform characteristics, and a waste feed with a solid concentration not exceeding 10%.

6.4. Anaerobic Digestion:

Process of Anaerobic Digestion is based on above mentioned technology; Biogas Induced Mixing Arrangement, BIMA Digester Technology. The main advantage of BIMA digesters is its mixing system (it doesn’t require mechanical moving parts), ability to control scum/sediments and handle high solids concentration. A biological desulphurization unit could be installed in the digester to reduce the H2S content of biogas.

6.5. BioCNG Collection:

The biogas, which is produced as a result of stabilization of the waste, leaves the BIMA digester automatically to the gas holder. The biogas consists of 55 - 65% methane (CH4) and 35-40% carbon dioxide (CO2). In place of a conventional gas holder which is prone to corrosion, a dry type gas holder made of a synthetic membrane (polyester) and suspended in a concrete silo, has been installed in the plant.

6.6. Bio-fertilizer Production:

The digested substrate leaving is dewatered through a screw press. The dried manure shows a much better availability of nutrients for the plants due to its bio-chemical composition. On daily basis Bio-fertilization plant could produce approximately 12741.6 kg of Bio-fertilizer, which can sell in the open market to farmers or horticulture department of Municipal Corporation.

7. Biogas as a Road Transport Fuel & Awareness Campaign:

Experience of Biogas as a vehicle fuel especially in Public Transport not yet started in India and other part of Sub-continent, which has around 30-35% of its population residing in Urban Centers. 

 

The given business model will involves several actors and institutions (highlighted below in the next section) who possibly play a key role in the implementation of the given project. 

Energy and environment are two most critical policy issues for governments and policymakers in developed and developing economies. But developing countries are the one, who are seriously encountering challenges in development and management of energy and environmental economy at micro and macro level.

This given project could illustrate the significance of clean energy Hybrid model and its approach of “top-down” and “bottom-up” to meet environmental and economic sustainability of Transport Services in Delhi through Biogas Buses by utilizing different forms of organic waste.

The externalities associated with this type of waste-to-energy project under renewable energy programme could possibly be seen as a window to future of energy and environment in India and other emerging economies. The significance of renewable energy & sustainable development can be explained by given below pie chart and graph.

                         Fig. 5. Composition of MSW by National Income

Above pie chart encourage the below graph from both policy and programme angle for Integrated Energy Production for BIOGAS BUS SERVICE. It suggests the significance of energy and environment.

The importance of given project in National Capital Region (NCR) and its possible positive impact on other municipal bodies is critical in shaping energy, environment and economy of emerging cities and urban centers in developing countries. Graph given below underlines the long term significance of Renewable energy and Sustainable Development policy adaptation in India and other emerging economies.  

 Fig. 6. Renewable Energy Policy

  • With no policy adaptation on renewable/green energy sector, the vulnerability of climate change will possibly increase and its impact on societies in developing countries will be far greater than the developed world (see red color curve in Fig.above).
  • Pink color curve indicates future impacts of climate change with the adaptation of renewable energy policy. The curve indicates less level of vulnerability and its impact on society and environment compare to no policy adaptation (i.e. red color curve).
  • The last curve in blue color indicates the low level of impacts, where we assume no climate change in future with renewable energy policy adaptation (less likely event).
  • Time line suggested under the diagram to analyze positive and negative impact of energy and environment policy is approximately 80-90 years from 2013.
  • This given project is a best case for Pink color curve which indicates adaptation of clean-fuel energy economy and its minimal impact on environment.

 

8. Conclusion

Anaerobic digestion is a mature and proven technology that will thrive under the right market conditions. Policies supporting anaerobic digestion for BIOGAS BUSES will empower communities to develop a biogas industry that would create jobs, improve the transport services, and agriculture industry’s image and generate significant economic returns.

The proposed project has a potential to thrive from all the three given angles of Sustainable Development; environmental sustainability, economic sustainability and social sustainability.
