Abdeen Mustafa Omer (BSc, MSc, PhD) is an Associate Researcher at Energy Research Institute (ERI). He obtained both his PhD degree in the Built Environment and Master of Philosophy degree in Renewable Energy Technologies from the University of Nottingham. He is qualified Mechanical Engineer with a proven track record within the water industry and renewable energy technologies. He has been graduated from University of El Menoufia, Egypt, BSc in Mechanical Engineering. His previous experience involved being a member of the research team at the National Council for Research/Energy Research Institute in Sudan and working director of research and development for National Water Equipment Manufacturing Co. Ltd., Sudan. He has been listed in the book WHO’S WHO in the World 2005, 2006, 2007 and 2010. He has published over 300 papers in peer-reviewed journals, 200 review articles, 7 books and 150 chapters in books.

Abstract:

This requires the harnessing and use of natural resources that produce no air pollution or greenhouse gases and provides comfortable coexistence of human, livestock, and plants. This article presents a comprehensive review of energy sources, and the development of sustainable technologies to explore these energy sources. It also includes potential renewable energy technologies, efficient energy systems, energy savings techniques and other mitigation measures necessary to reduce climate changes. 
There is strong scientific evidence that the average temperature of the earth’s surface is rising. This is a result of the increased concentration of carbon dioxide and other GHGs in the atmosphere as released by burning fossil fuels. This global warming will eventually lead to substantial changes in the world’s climate, which will, in turn, have a major impact on human life and the built environment. Therefore, effort has to be made to reduce fossil energy use and to promote green energy, particularly in the building sector. Energy use reductions can be achieved by minimising the energy demand, rational energy use, recovering heat and the use of more green energy. This study was a step towards achieving this goal.
Globally, buildings are responsible for approximately 40% of the total world annual energy consumption. Most of this energy is for the provision of lighting, heating, cooling, and air conditioning. Increasing awareness of the environmental impact of CO2, NOx and CFCs emissions triggered a renewed interest in environmentally friendly cooling, and heating technologies. Under the 1997 Montreal Protocol, governments agreed to phase out chemicals used as refrigerants that have the potential to destroy stratospheric ozone. It was therefore considered desirable to reduce energy consumption and decrease the rate of depletion of world energy reserves and pollution of the environment. This article discusses a comprehensive review of energy sources, environment and sustainable development. This includes all the renewable energy technologies, energy efficiency systems, energy conservation scenarios, energy savings and other mitigation measures necessary to reduce climate change.

Tianjin University, China

Title: The Recent Developments in Disposal and Recovery Methods of Oily Sludge
Biography:

My name is Khaled Waheeb.I was born in Yemen 1996.  I am  a chemical engineering student in the fourth year In Tianjin university, China. I have a research paper under review in Industrial &Engineering Chemistry Research journal named as “ Size effect of Ni Nanocatalyst on Supercritical Water Gasification of Lignin by Reactive Molecular Dynamics Simulation”. This review is my second work in the research field. Moreover, I have also participated in “ The 5th International Conference on Sustainable Chemical Product and Process Engineering”. I have passion in researches especially topics related to environment and I wish I can make a positive impact.

 

Abstract:

    The consumption and demand of oil are greatly increasing due to the rapid development in industry and energy field. Consequently, oily sludge is produced during the production, storage, transportation, and refining of oil. Oily sludge is considered as a hazardous solid waste; hence its treatment has become a worldwide mission and a hot topic for researchers. Oily sludge can be treated through two ways either sludge disposal methods or recovery methods. Sludge disposal methods can transform the oily sludge into non or less hazardous wastes to be safely discharged to the environment. While, recovery methods can recover valuable products from the sludge such as hydrocarbons, hydrogen, adsorbents and other useful raw materials. This paper provides a comprehensive review of recent studies in oily sludge treatments for both recovery and disposal methods, covering research papers in the period from 2014 to 2019. It is expected to give researchers an overview of recent development on the treatment methods, and to be regarded as a  reference for further research.

 

Esin G. Canli

Çukurova University, Turkey

Title: Uptake and Depuration of nanoparticles (Al2O3, CuO, TiO2) in tissues of freshwater fish (Oreochromis niloticus); Changes in ATPase activity in the osmoregulatory organs of fish
Biography:

Dr. Esin G. Canli has completed her PhD at the age of 30 years from Cukurova University (turkey) and postdoctoral studies from Aberdeen University. She has published more than 13 papers in reputed journals and attended many international congress. 

Abstract:

Metal-oxide nanoparticles (NPs) are being used in different fields of nanotechnology. Consequently, especially the aquatic environments can be contaminated by their waste products. In this study, fish were exposed to three metal-oxide NPs (aluminum, copper, titanium) in differing concentrations (0, 1, 5, 25 mg/L) for 14 d. Following the exposures, the activities of ATPases in the osmoregulatory organs of fish were measured. Additionally, aggregates of NPs in tissues of fish were demonstrated by TEM. Data showed that all NPs decreased significantly ATPase activities. In general, Al-NPs and Cu-NPs decreased significantly all ATPase activities in the gill and kidney at the highest and medium exposure concentrations. Similarly, Ti-NPs also decreased significantly all ATPase activities in the kidney at the highest and medium exposure concentration, though none of Ti-NP concentrations caused significant change in ATPase activity in the gill. Overall, data demonstrated that the least affected enzyme was Mg-ATPase and the least toxic NP was Ti-NP. TEM images demonstrated that all NPs accumulated in the tissues of fish in 14 days of exposure period, but not eliminated completely after 14 days of depuration period. There were considerable NP accumulations in the tissues of NP exposed fish. NP aggregates in the intercellular space and in the cells can be seen from the TEM images, suggesting decreases in ATPase activities occurred due to NP aggregates. This study demonstrated that NPs are able to cause changes in tissue structures and ATPases were very sensitive to NP exposures.

 

Yuchen Gao

Tsinghua University, Beijing, China

Title: Combination of waste utilization and syngas production via biogas dry reforming
Biography:

Ms. Yuchen Gao studied Environmental Engineering at Tsinghua University and achieved bachelor degree in 2016. Then she joined the research group of Prof. Jianguo Jiang at Tsinghua University for Ph. D study and will graduate in 2021. Her research interest mainly includes biogas reforming, catalysis and solid waste utilization. She has published 16 research articles in SCI(E) journals

Abstract:

Biogas dry reforming is a widely concerned technology which converts biogas into syngas. Many attempts have been taken for the synthesis of reforming catalysts. Industrial solid waste such as steel slag and coal fly ash is produced in large amount, which is rich metal oxides thus provides the feasibility in catalysis application. Here we propose the idea of combination of industrial waste utilization and biogas dry reforming. We used two-step activated coal fly ash as supports to synthesize catalysts. The activation measurements were useful for increasing the surface area and pore volume of support. BET and XRF analysis confirmed the changes in elemental composition. During reaction, the catalysts were found to be effective with CH4 and CO2 conversion rates > 95% at 850°C. Metal–support interaction was revealed by H2-TPR profiles of fresh catalysts. The catalysts we prepared was competitive compared with the traditional Ni/SiO2. This is a new approach for biogas dry reforming catalyst synthesis and high-value utilization of solid waste.
