 Kot Momin—There exists huge potential of Biogas production in the country, especially in rural areas, where the energy needs of domestic and industrial users can be met through this easily available and inexpensive source. this would also help reduce the energy shortages in the country. This was stated by the Chief Executive Officer (CEO), Alternative Energy Development Board (AEDB), Mr. Arif Alauddin while briefing a team of  journalists accompanying him on a visit to local Kino Factories.
Mr. Alauddin reiterated that the existing energy crisis in the country was more serious than anticipated; in fact, that was only one dimension of the picture, considering 40% people in Pakistan are without electricity and 60% without natural gas, and yet they pay five times more than the people in urban centres to meet their energy needs.
He said that the country during the last three years made significant progress in power generation through alternative / renewable energy (ARE) resources including waste to energy / biomass. He said that private sector, local and foreign both were being facilitated for investment worth billions of dollars in ARE sectors annually, as Pakistan offered lucrative fiscal and financial incentives to investors in this sector.
He said that a World Bank funded project for carrying out detailed study for Biomass / Waste-to-Energy projects in 20 cities of Pakistan had been initiated. Technical proposals had been evaluated by AEDB, and are now awaiting the World Bank concurrence to award the project. Another Waste to Energy Study, funded by USTDA is being carried out for Karachi to generate 10 MW power. He said that AEDB had also issued a LoI to set up a 12MW Biomass to Energy power project in Sindh, based exclusively on Agricultural Waste. The project is jointly sponsored by investors from US and local entrepreneurs, the SSJD Bio Energy. Another LoI has been issued to M/s Lumen Energia Pvt Ltd. to set up an 11MW power plant at Jhang, based on Agricultural Waste like cotton stalk, rice husk, sugarcane trash / bagasse, wheat chaff and other crops as multi-fuel sources.

Methane forming Bacteria

Methane-forming Bacteria


Methane-forming bacteria are known by several names (Table 3.1) and are a mor-phologically diverse group of organisms that have many shapes, growth patterns,and sizes. The bacteria can be found as individual rods, curved rods, spirals, and cocci(Figure 3.1) or grouped as irregular clusters of cells, chains of cells or filaments, and sarcina or cuboid arrangements (Figure 3.2). The range in diameter sizes of  individual cells is 0.1–15 mm. Filaments can be up to 200mm in length. Motile and
nonmotile bacteria (Figure 3.3) as well as spore-forming and non-spore-forming bacteria can be found.
Methane-forming bacteria are some of the oldest bacteria and are grouped in the domain Archaebacteria (from arachae meaning “ancient”) (Figure 3.4). The domain thrives in heat. Archaebacteria comprise all known methane-forming bacteria, the extremely halophilic bacteria, thermoacidophilic bacteria, and the extremely ther-mophilic bacteria. However, the methane-forming bacteria are different from all other bacteria. Methane-forming bacteria are oxygen-sensitive, fastidious anaerobes and are free-living terrestrial and aquatic organisms. Although methane-forming bacteria are oxygen sensitive, this is not a significant disadvantage. Methane-forming bacteria are found in habitats that are rich in degradable organic compounds. In thesehabitats, oxygen is rapidly removed through microbial activity. Many occur as symbionts in animal digestive tracts. Methane-forming bacteria also have an unusually high sulfur content: Approximately 2.5% of the total dry weight of the cell is sulfur. The of methane-forming bacteria are classified in the domain Archaebacteria because of several unique characteristics that are not found in the true bacteria or Eubacteria. These features include 1) a “nonrigid” cell wall and unique cell  membrane lipid, 2) substrate degradation that produces methane as a waste, and 3)

Farming for a higher purpose in Pakistan

The fertile alluvium deposited by the mighty Indus river and its tributaries in Pakistan have given the country’s demographic heartland of Punjab an agrarian edge. Yet, errant canal planning and over-pumping from tube-wells have degraded vast tracts of land. Salinity and water-logging afflicts around 6.3 million hectares of land and an additional 4,000 hectare of land gets affected every year (estimates from University of Agriculture, Faisalabad, Pakistan, November 2011). Climate change and conflicts over hydroelectric impoundment infrastructure have also made the arable lands of the country further vulnerable to flooding, as we saw in the epic floods of 2010 when an estimated 20 million people were displaced.
Amidst all these challenges to the farming economy of the country, there are glimmers of hope that Pakistan’s elite are trying to reconnect with the land in sincere and innovative ways. During my last trip to Lahore – the capital of Punjab province and Pakistan’s second-largest city (after Karachi), I was heartened to see urbanites retreating to farms in the surrounding countryside. Previously such farms were merely ornamental playgrounds of wealthy families but now there is a growing interest in these ranks to reconnect with the earth for societal good.
Zacky Farms, just outside Lahore, is the brainchild of Zafar Khan, a Caltech-educated software engineer who runs one of the most successful information technology companies in Pakistan named Sofizar. What started off as a recreational venture is now a side-business supplying sustainably produced organic milk, vegetables and meat to nearby Lahore suburbs. The farm is modeled on a cyclical model of minimal wastes and multiple product usage. The cows are fed pesticide-free oats, clover and grass and their manure is used to fuela biogas plant which runs the dairy facility. In an era of electricity load-shedding, such an alternative source of energy at a local industrial scale is immensely valuable to replicate as a development path. The residue of the biogas is used to fertigate the fodder fields and vegetable tunnels, which along with green manuring obviates the use of fertilizers. Free-range chickens grace the fields and there is even a fish farm on site. Zafar and his Ukrainian-born wife are committed to sharing their experiences with other farming entrepreneurs in the country.
Further south in a more rural and remote part of Punjab, famed writer and erstwhile lawyer, Daniyal Mueenudin, maintains a mid-size farm which is exemplifying other kinds of innovations. The farm does not boast ecological farming practices, apart from tunnel farming that can help with land conservation and humidity control. However, Daniyal has changed the social landscape of his area through implementing a “living wage” for all his employees. Noting the high level of inequality in Pakistan’s hinterland, the Yale-educated former director of the university’s Lowenstein Human Rights Clinic, is practicing what he preached. He also owns a farm in Wisconsin and could have a comfortable life in the States but his social obligations keep him ensconced in Pakistan for most of the year.
Raising the wage several-fold for works and farm manager, and also offering bonus incentives for performance, has led to positive competition that can help to erode the feudal levels of income disparity which exist in this part of Pakistan. At the same time, Daniyal is also committed to providing new livelihood paths for the agrarian workers as automation reduces farm employment in some areas. He has has fully funded a school and provided a merit-based scholarship for advanced degrees to students from the nearby village. One of the children from this school (the first in her family to even go to school) is now making his way through medical school in Lahore!
Zafar and Daniyal’s stories of commitment to constructive farming for social and ecological good may appear to be outliers but they are catching on and provide hope to a country which is all too often shadowed by despair.  In the suburbs of Islamabad, tax incentives and planning rules to encourage farming by urbanites are leading to a growing culture of reconnecting with the land in residential farms. In rural areas, the disaster caused by the floods of 2010 brought forth numerous aid agencies with new ideas for sustainable farming. The Pakistani diaspora, often known in the West for professions ranging from taxi-driving to engineering, may well find opportunities for reconnecting to their land in far more literal ways.  With growing commitment from land-owners it just might be possible to use the existential shock of recent natural disasters that have befallen the country into a proverbial opportunity for positive change.

Poo-Powered Car Gets a Spin around Bristol

The UK’s  first people-powered VW Beetle has taken to the streets of Bristol, in what has been hailed as a breakthrough in the drive to encourage sustainable power. Wonder what? Methane as a source of automotive propulsion isn’t exactly a new concept, but it’s taken manufacturers a long time to figure out how to clean it up enough to let it power an engine long-term.

ACETATE-FORMING BACTERIA and SULFATE-REDUCING BACTERIA

ACETATE-FORMING BACTERIA

Acetate-forming (acetogenic) bacteria grow in a symbiotic relationship with methane-forming bacteria. Acetate serves as a substrate for methane-forming bacteria. For example, when ethanol (CH3CH2OH) is converted to acetate, carbon dioxide is used and acetate and hydrogen are produced (Equation 2.3).
CH3CH2OH + CO2 Æ CH3COOH+ 2H2 (2.3)
When acetate-forming bacteria produce acetate, hydrogen also is produced. If the hydrogen accumulates and significant hydrogen pressure occurs, the pressure results in termination of activity of acetate-forming bacteria and lost of acetate  production. However, methane-forming bacteria utilize hydrogen in the production
of methane (Equation 2.4) and significant hydrogen pressure does not occur.  CO2+ 4H2 Æ CH4+ 2H2 O (2.4)
Acetate-forming bacteria are obligate hydrogen producers and survive only at very low concentrations of hydrogen in the environment. They can only survive if their metabolic waste—hydrogen—is continuously removed. This is achieved in their symbiotic relationship with hydrogen-utilizing bacteria or methane-forming
bacteria. Acetogenic bacteria reproduce very slowly. Generation time for these organisms is usually greater than 3 days.

Aerobic and Anaerobic Bacteria

Aerobic and Anaerobic Bacteria

At least 300 different species of bacteria are found in the feces of a single individual. Most of these bacteria are strict anaerobes. The majority of the remaining bacteria are facultative anaerobes. Escherichia coli is a common facultative anaerobe in feces.Bacteria from fecal wastes as well as hundreds of soil and water bacteria that enter a conveyance system through inflow and infiltration (I/I) are found in the influent of municipal wastewater treatment processes. For the purpose of this text, bacteria that are commonly found in wastewater treatment processes are divided into groups according to 1) their response to free molecular oxygen (O2) and 2) their enzymatic ability to degrade substrate in the anaerobic digester.

How A 32-Year-Old Deltan Built Biogas Plant

How A 32-Year-Old Deltan Built Biogas Plant


BY SUNDAY EGEDE
TO the uninformed mind, the concept of generating wealth from waste is an absolute impossibility; a myth that cannot be achieved or realized. The uninformed people in the society who do not understand the mechanics of science and technology hold on tenaciously to their belief that nothing good could come out from anything called waste. However, in recent time, there has been a dramatic shift in thought about what was usually considered waste.
Through scientific engineering process, wastes are now seen as means of solving myriads of socio-economic problems confronting man in his daily life. For instance, waste from farms, kitchen and animals (including human-beings) could be used for generating energy for cooking, heating, pumping water, driving machinery and generating electricity among others.
Only recently a 32-year-old Delta State born Engr. Ifeanyi Aghaulor singlehandedly built a biogas plant at his residence in Boji-Boji Owa, Ika North-East Local Government Area of the state using kitchen waste. In an interview with The POINTER on his outstanding technological breakthrough, Engr. Aghaulor who defined biogas technology as the use of biological process in the absence of oxygen for the breakdown of organic matter into biogas and high quality fertilizer, said biogas is a combustible mixture of methane and carbon dioxide.

KAPASIA, Bangladesh- For Amirunnisa Begum, cooking has become much less burdensome now that she doesn’t have to struggle with smoke from the wood she used to burn on her old stove.
Begum, 50, never enjoyed using the wood-fired cooker that filled her whole house with smoke. But like most residents of Kapasia, a sub-district of Gazipur, 130km northeast of the Bangladeshi capital Dhaka, she had little choice as natural gas is not available in the area.
But her options changed when a local representative of the state-run Infrastructure Development Company Limited (IDCOL) came and spoke to the community about using biogas as a clean-energy alternative to wood and oil.
“Cooking is much easier now as I can cook in a smoke-free atmosphere,” Begum told AlertNet. “It is also saving my monthly expenses on firewood and kerosene, and I am happy as I am doing something for the environment.” 
Begum uses dung from her four cows to produce gas in a small, domestic biogas digester she has installed just outside her house.

Bio- gas Plant Feeding

Bio- gas Plant Feeding

Three main cycle components as in full agriculture system are crop  farming, bio - gas plant and animal products. Each provides direct economic benefit to agriculture.

Biogas  -  Provides  energy to household uses Provides  organic fertilizer to improve the soil or for merchandise.

Mixing:  the water and dung mixture should be in the ration of 1:1.Stirring should be done well  to help  in  mixing the manure with the water. Proper mixing determines the functionali ty of the digester and production of the gas. 

NB: During the rainy season, the right slurry density should be attained.

Animal excrement : daily quantity of dung    added must be sufficient, if too much or too little is added, very little or no gas will be  produced as the bacteria does not have sufficient time to break down the manure.
Temperature: the effective temperature for bacteria to grow is 37C 
 If higher or lower than the suggested the bacteria will not develop, decreasing gas production.  The dig ester should not be constructed under tree shades. 

PH  Balance: A pH between 7- 8.5 is optimal. If below the suggested pH, gas will not be
produced . Ensure that the substrate fed is not too acidic or too basic. 

BIOGAS TECHNOLOGY


BIOGAS TECHNOLOGY

Biogas is  the  gas generated when bacteria degrade biological materials in  the absence of oxygen, in a process known as anaerobic digestion. Biog as is a mixture of methane (also known as marsh gas or natural gas, CH4) and carbon dioxide. It is a renewable   fuel which has for a long while (time) been  produced from organic waste treatment .
Biogas Diagram

 GENERAL OPERATION AND MAINTENANCE . 
  1.  Ensure the feed material is homogeneous (thoroughly mixed with water)   preferably at 1:1ratio,  before releasing into the digester. This will reduce the chances of settling substances along the inlet flow line.  
  2. Ensure the particles are as tiny as possible to increase the surface area for bacterial action.( This   may imply crushing of lumps and other huge particles)  or use of soft dung which has not been left to dry for a  long time .
  3. Antiseptics, pesticides and detergents should be avoided at all costs .
  4. Non- digestible materials should be avoided during feeding of the plant hence there should be proper selection when using other different feeds for the digester apart from cow dung. 
  5. Fittings and other accessories should be well fitted to avoid leakages.  (Gas outlet, water traps and valves should be occasionally checked for leakages).
  6. Clean the overflow once in two weeks time to avoid blockage of the expansion chamber.
  7. After using stove, valve must be closed and switch on the stove must be turned off. If only valve is closed it may cause rust on the switch. Grease the switch occasionally, and do not let it dry. Change a new switch when damaged as stove has been long used- Collins is this clear?

Electricity production from poultry waste is relatively new in Bangladeshi

Electricity production from poultry waste is relatively new in Bangladeshi. Most of the farms producing electricity from poultry waste have installed their electricity generation systems since 2005. However, Bogra Poultry Complex situated  in Bogra district in stalled its system in the late 90’s. This is the only poultry farm in  the country which meets its electricity demand from own generation. This farm is independent of grid electricity althou gh the farm is located under REB grid network. During th e field visit, it was found that Bogra Poultry Complex is using different technology than what other farm s are using at present in the country.  This
farm is using two Toyota engines of 1500 cc  capacity with a dynamo. The maximum output of the plant is 7.5 kW. The engines used in the  plant are old car engines and these engines are running alternatively. It  was found that biogas from the dige ster is fed into the engine only through a moisture filter unit to remove the moistu re content in the gas.  There is no device to remove hydrogen sulfide (H2S). The Figure show the different components used in the power plant in  Bogra Poultry complex.Faridpur Muslim Mission uses 3 of 4.5 kW natural gas generators. The plant was installed in
the year 2005. The generators used in the pl ant are Honda Model: EM6000GN, single phase and generate 220 V at 50 HZ. It runs 2 generato rs at a time and the duration is maximum 4 hours a day only when there is power outage. Th e generator can not run more than 4 hours a day. In this farm the biogas comes from the  digester through a Polyvinyl chloride (PVC) flexible pipe to the generators.  From the bioga s plant the PVC pipe is elevated up to a certain level so that the moisture condens ed in the pipe can go back to th e digester again. This allows it to remove a part of the moisture content in the biogas. To remove the rest of the moisture
content in the biogas it passes through a moisture filter before entering the generator which is placed near to the generator set. The moisture filter contains two sponges on the two sides and some silica gel in between. Like Bogra Po ultry Complex this plant also does not have any H2S removal system.

KESC Fast Working on One of the World's Largest Biogas Projects

Karachi Electric Supply Company, as part of its fuel diversification, green electricity generation and sustainable development vision, is planning the development of one of the world's largest Bio Waste to Energy Project of its kind near the Landhi cattle colony situated in Karachi. This plant is likely to have the potential of generating up to 22 MW of electricity fueled from biogas alone.

A localized Biogas plant is a socio-economically sustainable venture and reliable in comparison to wind or solar, which are vulnerable to extraneous variables, biggest being weather conditions. The Landhi Biogas project in Karachi will not only generate up to 22MW of green power but will also be producing up to 300 tons/day (tpd) of organic fertilizer as a meaningful byproduct. This organic fertiliser has special application in place of eroded soil which has lost it's utility and where standard urea fertilizer won't be effective. In addition to the above, this eco-friendly energy unit will also earn a significant amount of carbon credits, thereby making this Project economically viable.

Biogas news | From poo to power

From poo to power

Yorkshire Water in the UK is working with Esholt sewage works to build a biothelys sludge treatment plant that will create energy from human waste. The multi-million pound project will take effluent from the Yorkshire Water 750 acre sewage works, which currently collects waste from about 700,000 people, as well as about 300 litres of wastewater which it treats before dumping it into the River Aire. At the moment, about 26,000 tonnes of sludge is produced as a byproduct of the treatment process and this will now be used in Veolia's thermal hydrolysis system (biothelys), combined with anaerobic digestion, to produce biogas. Instead of being disposed of in landfill, the sewage sludge will be broken down in a thermal hydrolysis process that uses pressure and heat, before going through an anaerobic digestion system which creates biogas that can be used for the production of energy. The renewable electricity will be used to power the site so that it does not need to use mains electricity, which will reduce the costs of running the facility. Following this new added treatment, the sludge can also be used as a fertiliser or soil conditioner for a range of crops. Ben Roche, manager of energy and carbon at Yorkshire Water, says: ‘Each year we receive an overall electricity bill for approximately £45 million (€54 million) with 70% of our carbon footprint coming from electricity - a footprint that currently stands at 453,000 tonnes of CO2.’ ‘At the moment we already generate a third of the energy we use on site at Esholt through renewable energy technologies, but our aim is for this huge facility to become fully energy self-sufficient by 2015,’ he continues. ‘This pioneering technology will enable us to save around £1.3 million a year at this site alone which will help us in turn to keep customers' bills as low as possible.’ The plant is expected to take about 18 months to build and will be commissioned at the beginning of next year. Engineers Morgan Sindall and Grontmij have been chosen to work on the project
