Abstract:

From the environmental point of view there is a great interest in a recycling of packaging foils. Most of them are based on glycol modified poly (terepthalate ethylene)-PETG- printed with colorful inks. Therefore, there is necessary to rinse out inks from the foils first to make them processable. In the first step, the waste foils coming from different producers were characterized in terms of their structure and composition. It was found that they are similar to each other and that is possible to wash away all of the colorful inks in one shot with the appropriately selected medium. The comparison of properties of the foils before and after washing showed that there is no effect of the solvent used. In the next step the transparent foils after washing were dried and processed directly by the twin screw extruder machine in laboratory scale. Based on the results from thermal analysis (TGA, DSC) and rheological behavior (MFI index, shear modulus, complex viscosity) the processing conditions have been optimized. Finally, the effect of different processing temperature and number of cycles on properties of regrind material was investigated. The aim of the study was to analyze the possibility to use regrind PETG foil as a raw material. It would be add to pure PETG to decrease the costs of production or to mix with e.g., nanoparticles to provide new properties.

Abstract:

The growing demand for high efficient energy utilization of vehicles replaces hydraulic systems with electro-hydraulic actuators. The benefits of the electro-hydraulic system are energy recovery/storage, variable speed, power on demand, and reduced emission. In era of electric vehicle, the electronic components (motor, power electronics, and battery) for the electro-hydraulic system requires effective, reliable, and long-life time technologies. The authors present a recent research on the cooling technology applied for the development of an effective brushless direct current (BLDC) motor which electronically performs rectification without brushes. In general, BLDC motor is well-known to low noise, high durability and reliability. Nonetheless, unavoidable temperature increase during operation reduces the efficiency of the motor due to increased losses. The critical loss is resolved into iron and copper losses in accordance with the mechanisms. In this regard, a numerical model has been developed to simulate the losses induced by temperature increase. The numerical model is validated by conducting experimentation which presents excellent agreement with the simulation results. During the operation of the motor for 20 minutes, the temperatures increase up to 62.3°C and 32.2°C for stator and magnet, respectively. The authors also demonstrate air cooling structure to reduce the temperatures resulting in reduced losses, increased motor efficiency and durability.

Abstract:

Street lighting is one of most critical elements of urban infrastructure. It is a key service that public authorities need to provide for ensuring adequate lighting on roads, which leads to enhanced safety and security in the city, as well as improving visibility during evenings and night. The use of energy efficient technologies like LEDs has the potential to save costs because of reduction in electricity consumption. In India, the Urban local bodies or ULBs (also called municipalities) are responsible for deploying, maintaining and replacing the street lights. The primary financing options available to finance the lighting upgrades are via internal funding through capital budgets, debt financing or via energy performance contracts with Energy Service Companies (ESCOs). This study takes an innovative approach in conjunction with existing financing mechanisms, by partially utilizing a crowd funding framework to pay for the street lighting upgrades. The three pillars of this proposed model will be: ESCO, Municipality and the Citizens. The success of a Public- Public partnership model can prove to be the cornerstone of other such models in the energy sector. The municipalities can upgrade the infrastructure at no additional costs, and simultaneously cut down on their expensive operation and maintenance. After proposing a program structure, this paper will discuss the legal, economic, social and technical factors affecting the feasibility of the proposed structure in the Indian context. This work focuses specifically on tier 2 cities in India, which are defined broadly on the parameters of population (demographics), finance (living costs) and infrastructure (transport systems). This will be followed by a summary of the potential risks and challenges that are inherent in the model and how to address them.

She is presently working as a Junior Research Fellow (JRF) of the University Grants Commission sponsored by Indo-US 21^st Century Knowledge Initiative Programme Project No. 194-1/2009., entitled, “Foam –assisted CO₂ flooding for the depleted reservoir of Upper Assam Basin and candidate reservoirs in Louisiana”, Department of Petroleum Technology, Dibrugarh University.

Abstract:

In alkaline surfactant enhanced oil recovery (ASEOR) an alkali and surfactant/surfactants are used to recover the residual oil that remains after secondary brine flooding. The alkali, which is Sodium Hydroxide (NaOH) in this case, reacts with acidic components in the crude oil to form surface-active substances. A GC-MS spectrum of Upper Assam crude oil reveals the presence of carboxylic acid groups leading to in-situ formation of surfactants, which in turn decreases the interfacial tension (IFT) between the oleic and aqueous phases for better oil recovery. While the anionic surfactants used were Black Liquor (BL) and Sodium Dodecyl Sulphate (SDS). The Critical Micellar concentration (CMC) of BL and SDS one at a time was added to NaOH to enhance the effectiveness of NaOH in further decreasing the IFT of the Alkali-Surfactant (AS) slugs. The paper also make an attempt to study the adsorptive nature of the AS slugs. The best fit adsorption isotherm was derived by using SciDAVis scaled Levenberg - Marquaradt algorithm regression co-efficient.

Nima Moazami achieved his MEng degree with First Class Honors (Highest Academic Achievement in UK) and received his PhD degree in Mechanical Engineering at University of Birmingham, Birmingham, UK. He has been focusing on three major research projects i.e. Biomass-To-Liquid production via Fischer-Tropsch Synthesis, on-broad catalytic fuel reforming of gas and liquid fuels for hydrogen production and Organic Rankine Cycles for waste heat recovery. He is so determined to excel in these fields and generally, in alternative fuels and renewable energies, and to continue his work to advance the fields. His goal was always to make and will be making original scientific contributions vital and beneficial to the world as a whole. He has his expertise in mathematical modelling and simulation analysis and passion in production of ultra-clean transportation fuels and reducing emissions of particulate matter, CO and hydrocarbons, SOx and NOx as well as solving the world's current energy problems.

Abstract:

Liquid fuels produced from biomass via Fischer-Tropsch (FT) synthesis have great potential to produce high-performance, environmentally friendly clean and high-quality transportation fuels; mainly due to the absence of aromatic compounds, SO_x and NO_x. Currently, there are three main aspects for consideration regarding the FT synthesis processes. Firstly, there exists the FT synthesis reaction mechanism, the details of which are still not fully understood. Furthermore, from the outlook of chemical engineering, there is the design and scale-up of the commercial FT synthesis plant in which studies of the comprehensive mathematical modelling of the reactor hydrodynamics, reaction kinetics mechanisms as well as optimization study play significant roles. In fact, to reach the ideal performance of the FT synthesis process, a precise comprehensive mathematical modelling along with chemical reaction kinetics mechanisms that can describe the product distribution of FT synthesis is essential. This research has been focused on production of biodiesel (ultra-clean transportation fuels) from biomass via Fischer-Tropsch synthesis process at the presence of supported cobalt catalyst (37%Co/SiO₂). The aim was to develop a comprehensive mathematical model of a catalytic fixed-bed reactor along with comprehensive chemical kinetics model of Fischer-Tropsch synthesis reaction mechanism in order to investigate the conversion, as well as productivity and selectivity of gasoline, diesel and wax based on required application as this process can play a major role in solving the world's current energy problems and is crucial to industrial practice, being a prerequisite for industrial process design, optimization and simulation. Therefore, a novel kinetic mechanism along with comprehensive novel mathematical model of the fixed-bed catalytic FT synthesis reactor was established. The results indicated that the novel developed kinetic model based on a combination of alkyl/alkenyl mechanism for FT reactions (for production of n-paraffins and α-olefins compounds) along with formate mechanism for WGS reaction can provide the most accurate predictions. In order to enhance the performance of the FT synthesis process, first the parametric studies were performed to numerically investigate the effects of operating conditions on the catalytic performance of the fixed bed FT synthesis reactor over 37%Co/SiO₂. The reaction temperature, total pressure, space velocity and H₂/CO molar ratio were tested to see how effective they are. Those parameters that have the most significant effects were then included in the multi-objective optimization process in MATLAB programming software using advance Non-dominated Sorting Genetic Algorithm (NSGA–II) to optimize the productivities and conversion. My advance codes and optimization process gave rise to a set of trade-off optimal solutions, known as Pareto-optimal solutions. As a result, the Pareto-front solutions were established in order to be used as a dynamic database for the specific requirement. Different operating conditions from the obtained database were selected which privileged the optimization of a particular output for example increasing the production of bio-diesel fuel, increasing the conversion rate of bio-syngas species (CO and H₂), decreasing of CO₂ emissions, and decreasing the production of undesired CH₄ and lighter hydrocarbon compounds.

Abstract:

Mainstream economists have used various growth models to predict the interaction between sustainable economic growth and the endless accumulation of capital while environmental concerns and their negative externalities are left out, in most cases. In this paper, I will present a structural economic model that explicitly allows for the interaction between an economy and an ecosystem. The proposed model indicates that given a wide range of development and socio-economic infrastructure while population growth might be a reason for the constant growth trajectory, it has an adverse effect due to the constraints of resources and the environment. This is because economic activities and population growth increase ecological disordering as they downgrade the environment, while the later element has a negative impact on living standards. Considering different scenarios of utilizing renewable energy for economic growth, a feasible endurance factor for sustainable development might promote the methods of using the substituted energy and recycling methods. This, however, cannot be accomplished given the current speed and direction of technological progress and energy utilization and waste management.

Abstract:

Throughout the whole world, there are isolated areas where access to an electricity grid is too expensive. Diesel generators have been widely used for a long time because of the low initial cost, but at the same time, they have high running and maintenance cost. As a matter of fact, the diesel generator has many impact factors towards the environment such as producing of CO2 gas. Therefore, to avoid environmental pollution, global warming and ozone layer damage renewable energy sources are the appropriate alternative sources. With all renewable energy sources such as wind, solar, and geothermal, solar photovoltaic energy is primarily used because of its clean, pollution-free and inexhaustible nature. In the Middle East, especially in Saudi Arabia, the hot outdoor climate induces a necessity for cooling inside the buildings. Particularly, the solar radiations are significant throughout the whole year. Using air conditioning is very common in Saudi Arabia, and sometimes overused, leading to high peak loads for the electricity grid. Hence, the idea is to use the energy from the solar radiations to run the appliances and air conditioning system to reduce the peak demand on the electrical grid. In addition, when using solar panels, it is preferable to immediately use the solar energy than to keep it for later. Therefore, as to avoid using much electricity from the grid at night to run the chillers, the idea is to produce and store during the day by having the battery backup system.

Abstract:

The global energy prospective is quiet fluctuating. The energy markets are moving towards technological growth and environmental concern. In this aspect, Microbial fuel cells (MFCs) for conversion of organic matter into electricity for recovering green energy are becoming significant. Soil has been used to generate electricity in MFCs and shown several potential applications in today’s world. Whereas, usage of dried leaves having a high source of organic content with soil types in an MFC is not studied before and it is novel. The main aim of this study is to address the effect of soil types on the electricity production, nitrogen cycling and greenhouse gas emissions from MFCs loaded with dried leaves.

Methodology: Experiments were carried out in single chambered MFCs equipped with air cathode and carbon felt anode operated for 109 days at room temperature. Two different soil types such as sand and clay were used. Dried leaves were collected from Morgan Arboretum forest reserve, McGill University, Canada. Voltage readings with 500 to 1150 Ω external resistances were measured continuously for study period. MFCs were monitored regularly for gas emissions and changes in nitrogen compounds.

Findings: Sandy soil used in the study had 100% sand and clay soil had 40% clay, 38.5% silt and 21.50% sand. Dried leaves had 72% of organic matter with 42% of carbon content. Both MFCs with sand and clay soil with dried leaves gave continuous electricity production throughout the study period with maximum power density of 29.2 mW/m³ (1.9 mW/m²) and 23.8 mW/m³ (1.6 mW/m²), respectively. Clay soil MFC had higher methane emissions (27%) than sandy soil. Nitrogen profiles showed nitrogen uptake by soils and its possible nitrogen pathways.

Conclusion & Significance: The study demonstrated that the soil types with dried leaves have significant impact on electricity generation and nutrient cycling in MFCs. It has potential for production of renewable energy and climate change mitigation.

Abstract:

The environmental issues such as global warming, climate change, and environmental pollutions, are defining challenges for the 21^st century. Studies show that the reduction of the energy demand for heating and cooling, as the most energy consumers in building sector, is the key factor in the low energy houses. This paper focuses on the courtyard housing typologies, which were traditionally known for their distinctive passive cooling performance and can contribute meaningfully towards achieving a sustainable building design with high energy efficiency in all regions, particularly in hot-arid climates. The goal is to propose an optimized low-energy design model for courtyards regarding orientation, geometrical properties, and the materials, to provide the maximum thermal comfort for residents. After a comprehensive literature review, the Design Builder software package was employed to develop a three dimensional numerical building model to simulate a courtyard house in BW climate of Phoenix in Arizona, as a research case. The model was verified using data from previous research including indoor and outdoor temperature, and residents’ thermal comfort, and close agreement was achieved. The effects of three main design variables were studied, including orientation, geometrical properties (dimensions and proportions), and materials, on residents’ thermal comfort in the courtyard to achieve most efficient design. Interactive correlations between the design variables were quantified and an optimization was conducted, using Rhinoceros plug-in Grasshopper, in order to maximize thermal comfort for residents and minimize energy consumption related to building heating and cooling. A nonlinear equation were derived based on the optimization investigation to be used in designing courtyard houses in hot-arid climate, which can aid designers to design most-efficient low-energy courtyard houses in this region.

Bedoshruti Sadhukhan has a Master’s degree in Environmental Management, and more than 12 years of experience in project management, training and capacity building in the field of environment management, environmental justice, environmental impact assessment, public participation in decision making, water, waste and climate resilience. She has also worked on Human Rights Issues such as housing rights and tribal rights. She is a Key Member of the ICLEI South Asia sustainability team and manages long term international projects on environmental management systems for local governments, climate resilience, water, sanitation and solid waste management in South Asian countries.

Abstract:

With increasing population, economic development and a growing consumerism, South Asian cities are facing a significant change in waste generation and its characteristics. Managing waste has always been the responsibility of local authorities (LAs), but the age-old practice of dumping waste is no longer sustainable. It is an inefficient way to use limited land resources, causes environmental pollution of soil and ground-water, social impacts through health issues of nearby communities and is an overall unsustainable practice leading to loss of valuable material resources. Obviously, LAs need to look for sustainable options of reducing, reusing and recycling waste. Integrating the existing system of informal waste-pickers in South Asia, who dominate recycling even before the waste enters the formal management system, can lead to significant environmental (material recovery), social (health) and economic (livelihood options) benefits. ICLEI South Asia conducted a project in 7 South Asian LAs, encouraging them to promote waste segregation and recycling, particularly through informal sector, to move towards a zero-waste community. Successful pilot projects in the cities, demonstrated how recycling helped to reduce waste going to landfills, produced resource materials including compost, and generated livelihood for waste-pickers in the city. Continuous engagement with local communities and waste pickers ensured the continuity of the pilots even beyond the life of the project. Critical to successful recycling is simultaneous segregation of waste at source, which relies heavily on the awareness levels of community, as well as well-established linkages with recycling units which will take up the segregated recyclables. Moving towards zero waste in cities needs collaboration with state and national government agencies so as to incorporate all types of waste, since LAs are only responsible for municipal waste, which technically excludes medical waste and hazardous waste, but which are major components of the waste coming out of cities.

Ruwani Kalpana Jayawardana has experience in using silicon sources both chemical and natural for enhanced growth and disease tolerance in plants. She has a passion in improving plant growth performances by environmental friendly sources and utilizing agricultural waste for improving soil physical, chemical and biological properties. She has contributed to develop a cost effective hydroponic nutrient solution with silicon. In her MPhil research study, she has found that a low cost simplified hydroponic system with paddy husk in the media as effective way of Si nutrition to enhance anthracnose disease resistance in capsicum.

Abstract:

Statement of the Problem: Paddy husk (PH) is an agricultural waste which has not been utilized properly worldwide. Mostly it is left unused as waste or simply burned in the field creating significant environmental problems. It is expected to have about 700,000 tons of paddy husk production in Sri Lanka in year 2020. PH is an organic nutrient source particularly rich in silicon.

Methodology & Theoretical Orientation: Experiments were conducted to investigate the effect of incorporation of PH in the growing substrate to improve plant growth, yield and disease tolerance. A simplified hydroponics system (SHS) with PH and sand (3:2 v:v) media was tested on capsicum plants. In addition, the effect of amendment of soil media with different ratios of PH was investigated on Capsicum annuum L. The effect of amendment of potting media of rubber nursery plants with 20% of PH charcoal or PH ash was also studied.

Findings: More than 50% of soluble Si was detected in the nutrient solution of SHS as measured by colorimetric method. SHS was effective for increasing fruit length, fruit weight, shoot length, root length with 83% of reduction of anthracnose disease. In the pot experiment, it was revealed that incorporation of 60% of PH in to soil would be effective for reducing anthracnose disease of capsicum. Significant improvement of plant diameter was reported in rubber nursery plants when potting media was amended with either PH charcoal or PH ash.

Conclusion & Significance: In case of anthracnose disease of capsicum, use of PH would be an environmental friendly control measure. The findings open path for future investigations on the effect of different forms of PH for enhancing performance of different plants. Further investigations should be conducted to find the vital nutritional potentials of PH and prevent it disposing as waste.

He has published in recycling and has been a Noted Speaker at the 2015 Southeastern Recycling Conference in San Destin, Florida and the 2015 Georgia Recycling Coalition Conference on St. Simons Island, Georgia.

Abstract:

A common reason given for not recycling is that it is not cost effective and too costly to do. To be successful is easy but one should shift paradigms to make it work. Whether you are an educational campus, training facility or community, it can be done effectively and efficiently. It will take a shift in culture and thinking in the beginning. That first shift is to stop thinking of all solid waste as “trash”, but rather a commodity that has monetary value in today’s market place of shrinking resources. Recyclable commodities such as old corrugated cardboard (OCC), standard office paper (SOP), aluminum drink cans are no different that gold, orange juice, or pork bellies, they are sold to those companies that need the recyclables as raw material to keep their mills operating, personnel employed, and their products flowing into the stream of commerce around the globe. These recyclable commodities are crucial to saving natural resources when they are processed back into their natural states to begin the manufacturing process all over again. Aluminum can be recycled indefinitely and results in a 95% energy savings and reduces pollution by 95% over tradition saves 4 lbs. of bauxite from being smelting for pound of aluminum recycled. Recycling not only generates positive revenue streams but also, saves natural resources, but also allows for cost avoidance associated with traditional waste collection and disposal.

Abstract:

Climate change is affecting birds worldwide. Such impacts have always been prevailing due to rising temperature or unpredictable rainfall that might be too abundant or little and which in turn bring about dire consequences upon the lives of the endemic bird known as Bali Myna (leucopsar rothschildi). In this paper we propose a framework analysis describing the possible patterns of change in the distribution of Bali Myna (leucopsar rothschildi) population based on climate parameters such as temperature, rainfall and humidity in hope to better have an improved quantitative methodology meant to identify and describe these patterns. This study uses a descriptive qualitative method recoursing to focus upon sites observation and a deep interviews to be carried out while using SPSS 16 in order to know the variables correlation in hope to determine the plausible significance between them that allow us to analyse the effects of environmental variables on bird species in this study. We tested the proposed methodology using data from the West Bali National Park and the existing data of climate variables over the last decade where climate variables are considered to be significant factors influencing the lives of Bali Myna (leucopsar rothschildi). This study discovers that increases in temperature and precipitation each year have adversely affected the number of Bali Myna (leucopsar rothschildi) population indicating that the bird’s survival capacity depends largely much on temperature. Besides, it has been perceived that Bali Myna is very reproductive in rainy season but its fluctuations whether high or low impacts them as well. The distribution mapping show a decline of population in 2006 while an increase was perceived during the last five year period of 2011-2015. Besides, over the same period, a slight increase of 0.4 °C in mean temperature was noticed, precisely in Cekik our research site where Bali Myna (leucopsar rothschildi)

Abstract:

A large portion of municipal plastic wastes consists of significant amount of polyvinyl chloride (PVC) products containing hazardous chlorine element. During their disposal activities, such as incineration, a lot of toxic chemicals including hydrogen chloride, chlorine gas, dioxins, and furans can be released into environment. Therefore, proper development of selective separation methods of PVC containing chlorine is necessary before applying disposal or material recycling processes. However, it has been difficult to separate selectively PVC from mixtures of plastics having similar appearance density, i.e. PVC and PET mixture (PET 1.38 g/cm³ and PVC 1.42 g/cm³). This study presents a one-step selective separation technique of PVC using H₂O₂ solution, to promote hydrophilicity development on PVC surface, under ultrasonic irrigation. The ultrasonic treatment helped to decrease air bubbles attachment on PVC surface, which can make settling down of treated PVC to the bottom of the flotation reactor. However, the PET treated under the ultrasonic environment was easily floated over because it was still kept hydrophobicity. The combined treatment of low concentration of H₂O₂ and ultrasonic irrigation for 30 min showed 100% purity and recovery of the PVC separated from PET, which could be a suitable and inexpensive way to improve plastic recycling quality through selective separation of PVC with selective building of hydrophilicity on PVC surface.

Abstract:

The integrated management of media based (both water and air) pollutants is the vital at current as the management and legalization of individual pollutant is very difficult. Integration of various environmental aspects associated with activities of production processes is one of the challenges in industrial sectors. It is of vital concern to find the scientific way of integration of media based pollutants for today. Based on amount and kind of media based pollutants, Integrated Environmental Performance Score (IEPS) is calculated applying Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI). The potential impacts of individual pollutants have been modeled for water-based pollutants viz., Chemical Oxygen Demand (COD), Total Phosphorous (TP), and Total Nitrogen (TN) and air pollutants viz., Oxides of Nitrogen (NOx), Oxides of Sulphur (SOx) and Particles Matter (PM10). A kilogram of individual pollutants is taken in modeling to compute the individual impact categories of unit pollutants. The EPS penalty of TN is obtained as highest score of 189.70 i.e. 90.82% shares among six pollutants. The total penalty score for TP, PM10, TN, NOx and SOx, is derived as 13.53 (6.48%), 2.59 (1.24%), 1.30 (0.62%), 1.30 (0.62%) and 0.44 (0.21%), respectively. Hence, it is necessary to integrate effects of pollutants as per the scientific and justified impact caused by individual pollutants derived from the industrial facilities. Therefore, this study recommends for the compliance of EPS penalty of the pollutants based on a result of TRACI. This helps to enforce a scientific and justified polluters’ pay principle.

Abstract:

Geopolymer is a new technology towards greener environment as it utilizes industrial waste like fly ash, metakaolin, blast furnace slag, etc in bulk quantity. The geopolymer technology was first introduced by Professor Joseph Davidovits of France in 1978. His work shows that the adoption of the geopolymers could reduce the CO₂ emission caused due to cement industries. The development of geopolymer system is an important step towards the production of environment friendly materials. Geopolymerization involves a chemical reaction between various alumino silicate precursors with alkali metal silicates under strong alkaline conditions yielding polymeric –Si-O-Al-O- bonds, which lead to geopolymers by polycondensation. In present research work an attempt has been made to develop high strength geopolymer mortar using industrial waste fly ash from Satpura thermal power plant Sarni (M.P) India and Rice husk from agro industries. Sodium hydroxide and Sodium meta silicate were used as conventional alkaline activator. Rice husk was used for the synthesis of in-situ silicates for development of inorganic organic hybrid alkaline activator. For the first time this inorganic organic hybrid alkaline activator was developed by CSIR-AMPRI Bhopal India for multifunctional applications. Patent filed in India and USA and its application number is 0088NF/2016/201611019506 Dated 30, March 2016. The developed inorganic organic hybrid alkaline activator was used with conventional alkaline activator in different percentages by weight of fly ash. The percentage range chosen were 0.5%, 1%, 1.5%, 2%, and 2.5%. Fly ash based geopolymer mortar cubes samples were thermal cured in hot air oven for 48 hours at 60 ℃ and then the cubes samples were left at ambient temperature. Five batches of inorganic organic hybrid alkaline activator and one batch of reference conventional geopolymer mortar were mix design and three cube samples for each batch were tested at 3, 7 and 14 days respectively for compressive strength. The conventional geopolymer mortar prepared with alkaline activator of optimized 12.5 molar solution. The compressive strength of conventional geopolymer mortar was found to be 35.9 MPa at 14 days which was compared with the geopolymer mortar developed using inorganic organic hybrid alkaline activator and it was found that maximum compressive strength of 55 MPa at 14 days was achieved after adding 2% of inorganic organic hybrid alkaline activator. The developed high strength geopolymer mortar can be used for production of prefabricated building components.
