Rajasthan priorities outdoor air pollution, bhattacharjya
This document summarizes information about brick production in India and Rajasthan, and analyzes two potential solutions to improve the sector's social and environmental impacts. It notes that traditional brick kiln technologies are energy intensive and heavily polluting. Two improved kiln options are assessed: zig-zag kilns and vertical shaft brick kilns (VSBKs). Both use less energy and emit fewer emissions than traditional kilns. An economic analysis finds that switching to these cleaner technologies would yield substantial private financial benefits as well as social benefits from reduced health impacts and carbon emissions valued in billions of rupees, with benefit-cost ratios above 5 for VSBKs and above 7 for zig-zag kilns.
Project Planing
The document discusses the history and present situation of compressed natural gas (CNG) in Bangladesh. Some key points:
- CNG was introduced in Bangladesh in 1982 when fuel oil prices spiked internationally. It is cleaner burning than gasoline or diesel.
- Current CNG usage is growing but remains below capacity, with around 19,000 vehicles but only 10,000 three-wheelers and 3,000 taxis using CNG.
- The government aims to further convert its own vehicles to CNG and allow private conversion to increase adoption rates.
- CNG is cheaper and more environmentally friendly than gasoline, but establishing CNG refueling infrastructure requires significant initial investment.

This document discusses capturing carbon dioxide (CO2) from power plant flue gas and depositing it underground. It analyzes depositing the waste gas from a power plant in Sırnak, Turkey underground. The goals are to store the CO2 in underground coal mines and use the space. Models show the CO2 capture costs decrease when combined with coal bed methane extraction, as the methane enhances CO2 sequestration in excavated coal seams. With projected methane yields of 200,000 cubic meters per year, CO2 capture and storage costs could drop to around $11 per ton of CO2.
Green Concrete- A need for the future
Green concrete is an environmentally friendly alternative to traditional concrete that uses recycled and sustainable materials to reduce its carbon footprint. It can reduce CO2 emissions by 80% compared to traditional concrete by using industrial wastes like fly ash instead of Portland cement, and recycled concrete aggregates instead of virgin materials. The main objectives of green concrete are to lower greenhouse gas emissions, reduce energy and resource usage, and promote more sustainable construction practices. Its use could help India address issues from its booming construction industry like waste disposal and environmental impacts, though more research and awareness building is still needed to increase adoption.

emission factors for continuous fixed chimney bull trench brick kiln (fcbtk) ...INFOGAIN PUBLICATION
Uncertainty in emissions from brick manufacturing is a major concern and more primary monitoring based datasets are required. This study presents latest emission factors for continuous fixed chimney bull trench brick kilns (FCBTK), which is the main technology used for brick production in India. Stack monitoring of kilns in a typical brick manufacturing cluster in India is carried out to monitor emissions of pollutants like PM, SO2 and CO. Average concentrations of PM, SO2 and CO in the stacks are measured to be 172±76, 114±47 and 484±198 mg/Nm3, respectively. Monitored stack concentrations are used to compute emission factors based on brick production and fuel consumption activities in the cluster. The computed emission factors across different kilns ranged between 0.81-1.18, 0.57-0.71 and 2.07-2.80g/kg of fired bricks for PM, SO2 and CO, respectively. Corresponding emission factors per unit of coal used in brick kilns are found to be in the range of 13-29, 9-15, 40-56 g /kg for PM, SO2 and CO, respectively. The differences in emission factors are mainly due to variations in the quality of coal used by different kilns. Good correlations were observed between changing calorific values, ash and sulphur content of coal and emissions monitored in the kilns. These new factors can be used for improvement in emission inventories and thereafter modelling results for the region.Similar to Air Pollution Abatement Green Brick Technology (20)

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

Air Pollution Abatement Green Brick Technology
- 1. Air Pollution Abatement Green Brick Technology
- 2. Introduction Air pollution by brick kiln is mainly because of using outdated technologies which are energy intensive and highly polluting. To mitigate this problem, adaptation of modern clean technology is obvious. Because of eco-friendly nature, this technology is popularly known as ‘Green Brick Technology.
- 3. Overview of Brick Making Industry in Bangladesh
- 4. Bangladesh has about 6000 authorized brick fields and numerous illegal ones. Existing Technologies are Mainly Fixed Chimney Kiln(fck) and Bull’s Trench Kiln(btk) Most of them are operated as small unit and seasonal.
- 5. Brick making industry is a significant sector in Bangladesh contributing about 1% to GDP and a source of about 1 million people. Despite enormous importance it’s role is getting controversial because of being a prime source of air pollution in adjoining areas. It contributes about 40% of fine particulate matter pollution in cities.
- 6. ‘’ In Bangladesh, about 90% of brick fields use high polluting technology. These conventional technologies use raw fire woods and low graded coal as fuel. Emissions from brick kilns are mainly very harmful gases including SOx, NOx, CO2, CH4, suspended particulate matters ( PM 2.5, PM 10) How Air is Polluted by Brick Kiln?
- 7. Fixed chimney kilns are one of the main polluters in Bangladesh.
- 8. Potentiality of Green Brick Technology in Bangladesh Some pilot projects had been conducted in association with ADB and UNDP in Bangladesh. From the reports of these projects, the potentiality of green brick technology can be illustrated as follow • Environmental Aspects • Economical Aspects • Health Aspects • Social Aspects
- 9. Hybrid Hoffman Kiln (HHK) Vertical Shaft Brick Kiln (VSBK) Improved Fixed Chimney Kiln (IFCK) Improved Zigzag Kiln (IZigzag) Green Brick Technologies
- 10. Hybrid Hoffman Kiln (HHK) Developed in Germany Uses coal or natural gas It combines fuel injection and external firing in insulated kiln High quality brick with reduced emissions.
- 11. Improved Fixed Chimney Kiln(IFCK) Use of internal fuel. Back process mechanization. Improved firing practices and operating system. Filtration of flue gases.
- 12. Improved Zigzag Kiln(IZigzag) Improved Zigzag is the improved and standard version of Zigzag kiln which leads to lower emission and higher energy efficiency . Improvements are use of internal fuel and better flue gas scrubbing. Less efficient and less familiar than other green brick technologies in Bangladesh.
- 14. Environmental Aspects • Low consumption of energy and less emission. • It involves using of internal fuel. • It emits low load of PM. • Topsoil uses are very little affected. • New technologies do not use fire woods.
- 15. Technology Coal consumption (t/100,000 bricks) Particulates (SPM) (mg/m3) CO2 emissions (t/100,000 bricks) CO2 emission reduction (%) FCK 20-22 1,000 50 n.a. IFCK 16-18 < 500 40 20 Zigzag 16-18 270-300 40 20 HHK 12-14 20.3 30 40 VSBK 10-12 78 -187 25 50 Environmental Aspects
- 16. Economic Aspects • Green brick technology consumes less fuel. • Automated, thus less labor cost. • Assistance from Govt. and private banks. • Extremely high demand. • Quick and secured recovery of investment, may with in 1 year.
- 17. Health Aspects
- 18. Health Aspects • Less emission of particulate matters hence less health damaging. • More safety in working place. • Less dust and other pollution • Less risk of respiratory diseases.
- 19. Social Aspects • Women can work . • It benefits both owners and workers as it brings more money than traditional one. • Green brick technology can be operated round the year, hence eliminates migration problem and job unavailability of workers.
- 20. Conclusion Due to energy insufficiency, environmental pollution, and less production; existing brick technologies should have to be upgraded or replaced to keep pace with rising demand. In that case, the adaptation of green brick technology is the only one rightful choice to abate air pollution and to insure sustainable brick production.
- 21. Thank You!
