Speech Title: Development Status and Suggestions of Sustainable Aviation Biofuel


Mr. ZHOU Mu  

Department of Airworthiness, Civil Aviation Management Institute of China, Beijing, China

Abstract: Sustainable aviation biofuel (SABF) is a promising solution for aviation emission issues, but its sustainability and related technical standards need to be further studied. With sustainability and technical standards as key factors, this work firstly reviewed the mechanism of the Carbon Offsetting and Reduction Scheme for International Aviation and its impact on China; then introduced the International Civil Aviation Organization (ICAO) SABF greenhouse gas (GHG) emission value and emission reduction calculation method, analyzed the similarities and differences between ICAO and China GHG emission reduction calculation, discussed the Chinese and international technical standards for aviation biofuel verification, briefly described the application of aviation biofuel in and outside of China; finally reviewed the main challenges  for fostering aviation biofuel in China, such as imbalance between demand and supply. To deal with these problems, some suggestions for SABF development were presented: Enhance integration between international and domestic carbon markets, accelerate the construction of aviation biofuel sustainability certification system, establish the minimum mixing ratio for SABF, etc.

Abstract: Facile and control sized cadmium sulphide (CdS) quantum dots (QDs) and cellulose nanocrystals grafted polyvinylpyrrolidone (CNC-g-PVP) doped CdS QDs were prepared via co-precipitation. Doped and Undoped CdS QDs exhibited excellent optical properties. The proposed method is effective in removing industrial polluted water and bactericidal treatments of organic contaminants such as methylene blue (MB). In order to determine the structural, optical, and morphological properties of the produced samples, a number of different characterization procedures were utilized. The X-ray diffraction (XRD) pattern confirmed the structure to be hexagonal, and there was no discernible shift in the spectrum as a result of the addition of 2, 4, or 6% doping. Doping causes a blueshift in the absorption pattern, which is described by the UV–vis spectrophotometer. This shift leads to an increase in band gap energy (Eg). In comparison to the acidic medium, the findings of the catalytic activity (CA) against MB in basic and neutral media were impressive. In addition, the bactericidal potential of the doped sample (6%), which was tested against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), both of which are Gram-positive bacteria, exhibited significantly higher inhibition zones. These zones measured 5.25 mm and 4.05 mm, respectively.

Abstract: The global energy land scape will change more in the next ten years than in the previous hundred. The world is moving towards greener energy obtained from renewable energy sources. Powering A sustainable and profitable energy via green nanotechnology will be a solution to build a greener and more sustainable future. Until now, plants are still highly esteemed all over the world as a rich source of greener energy. Over the past few decades, researchers have focused on green energy, from botanical sources. Green chemistry, as a work philosophy, has contributed to the design and application of safer and green processes and products. This study provides an overview for the green chemistry and green engineering principles that could be instrumental in sustainable biofuel process development. In the current scenario of energy security, the pursuit of alternative energy sources is very important to utilize the non-edible plant resources via phytochemical screening leads to renewable and cleaner energy. Decarbonization is mission-critical for the planet. A viable solution to present-day problems like fuel crises and environmental pollution is to move away from fossil fuels towards renewable energy resources. The main focus of this project is on the biosynthesis via nanotechnology using advanced analytical techniques (TLC, HPLC, GC-MS, FT-IR, NMR, EDX, SEM) and biological techniques to isolate some novel bioactive phytochemical entities for future applications in cleaner energy production. Currently, academia, society, industry, and government are concerned about the application of greener and cleaner principles. The worldwide concern for the sustainable future requires balanced between legacy systems, emerging technologies, business, economy while better managing assets risk and carbon emissions.

Invited Speech IV

Speech Title: Characteristics of Hydrolytic Indigenous Bacteria as Degradation Agent of Hospital Wastewater: A Case Study in Central Java


Dr. Stalis Norma Ethica  

Postgraduate Department, Magister Study Program of Clinical Laboratory Science; Universitas Muhammadiyah Semarang, Central Java, Indonesia

Short Biography

Dr. Stalis Norma Ethica is a full-time lecturer and researcher with industrial laboratory experience. She focuses in the utilization of bacterial cells and enzymes as bioremediation, medicinal, and diagnostic agents, supported by encapsulation and genetic engineering technologies. She has been a full-time lecturer (assistant professor) in the Postgraduate Program of Magister of Clinical Medicine since 2019. The Indonesian Ministry of Research and Higher Technology funded her works on developing bioremediation agents for hospital wastewater from indigenous bacteria and developing antithrombosis and antibiofilm agents from marine bacterial enzymes.

Abstract: Hospital wastewater is a source of hazardous matters including toxigenic chemicals and pathogenic microorganisms. In the last few years, the initial steps in developing bioremediation agent to treat hospital wastewater have been initiated. The strategy was focused on degrading organic matters in order to improve BOD parameter of hospital wastewater and repressing the growth of pathogenic bacteria present in the waste by propagating the population of beneficial bacteria. Recent studies have been conducted to isolate and characterize hydrolytic indigenous bacteria from wastewater samples obtained from hospitals in the Central Java. In the process, it was found that hydrolytic indigenous bacteria demonstrated the desirable characteristics to be used as degradation agent. The characteristics include Low pathogenicity, ability to produce multiple hydrolytic enzyme production, ability to synergically work as consortium, ability to improve BOD (Biological Oxygen Demand) parameter, and versatility to be microencapsulated. Such characteristics make them a great candidate of bioremediation agent.
