Title: Production of Antifungal Agents in a Microbial Fuel Cell (MFC)
Biography:
Takashi Ano is a professor of Kindai University. He lives in Osaka, Japan. His bachelor, master and doctor degrees were awarded from Osaka University. His major fields are biocontrol agents, and microbial fuel cell aimed for the sustainable society, and has published many papers in the field (https://researchmap.jp/read0008399/?lang=english). He had worked in Tokyo Institute of Technology for 20 years as a research associate, and an associate professor.
Abstract:
World population is now increasing, and the United Nations predicts that the world population will be 9.8 billion by 2050. The major concern is that this population increase will lead to food and energy shortages. A microbial fuel cell (MFC) is a device that produces electric power by recovering electrons generated on an electrode when microorganisms with electrochemical activity decompose an organic substance. MFCs can simultaneously perform wastewater treatment and electricity production, by using an organic substance in wastewater as a nutrient source for microorganisms. To increase agricultural productivity, utilization of pesticides are necessary to solve the food shortage. In recent years, biocontrol agents are attracting attention, because of the smaller burden on the environment compared with chemical pesticides. We tried to produce electricity and antibiotics at the same time using the MFC by Bacillus subtilis RB14, an antifungal substance iturin A producer. As a result, it was recognized that electricity production after the 10th day of the cultivation and antifungal activity of the culture supernatant from the MFC against Rhizoctonia solani K1. It seems to be the first finding that the electricity generation and the production of an antifungal substance by B. subtilis in the MFC, and it is expected that the production of a biocontrol agent from the waste material and also the generation of electricity during the process in the same apparatus. This may open a new method for the waste material treatment and the low-cost production of biocontrol agents with the recovery of energy as electricity.

Title: Realizing the true potential of Recycling in a circular economy with Nexus Thinking
Biography:
Hiroshan Hettiarachchi is a civil engineering professor from the United States and currently serving as the Head of Unit – Waste Management at the United Nations University (UNU-FLORES) which is an integral part of the United Nations system. Before joining UNU in 2013, he previously served at Lawrence Technological University, in Michigan, USA, where he held the position of Director of Civil Engineering Graduate Programs from 2010 to 2013. His work covers multiple topics including, sustainability, circular economy, environmental resources management, waste management, and geotechnical and geoenvironmental engineering.
Abstract:
The demand for resources or what we take from nature is on the rise for many reasons, and so does the waste generation. Recycling is certainly a sustainable way to conserve resources. However, recycling itself is not able to address the increasing resource demand and waste generation issues. This requires a holistic approach that entails the whole process of consumption. The process of consumption as we traditionally know of is based on a linear economic concept of take-make-use-trash. We “take” natural resources to “make” products for our “use.” Whatever is left after make/use is what we “trash” as waste. Circular economy presents us the most sustainable alternative to linear economy that we practice today. What circular economy teaches us is minimizing both take and trash by using the material, that we have already borrowed from nature, as many times as possible. This means that the make/use steps should ideally go in a circular pattern which is also why the process is called circular economy. One may wonder why circular economy is yet to become popular despite the sound argument it offers. It is just not so easy to walk away from the linear economy concept that we have been using for thousands of years. Transitioning to a circular economy requires us to train ourselves to think and act differently. This talk focusses on how we may benefit from nexus thinking of integrated resources management as a catalyzer to transition to a circular economy to realize the true potential of recycling.

Title: Waste Recycling and Reuse is the major industry for the reduction of global poverty and hunger in the developing countries of the world like South Asia particularly in Pakistan
Biography:
Mr. Muhammad Usman, Former Director General of Agricultural Research System, Govt. of Pakistan who retired from service after a spotless career of about 35 years (1974-2009) with senior level experience work on the research and development of integrated agricultural industries like livestock and dairy development, aquaculture and fishery, apiculture and poultry, on a sustainable way.
Abstract:
The aim of presentation consist of waste recycling, reuse, industry, production, income, employment, economy, crises, poverty and hunger were study and reported that Waste Recycling and Reuse is the major industry for the reduction of global poverty and hunger in the developing countries of the world like South Asia particularly in Pakistan. The study reported that unless you have been on another planet for the last century, then you have probably heard of it. Recycling is the process of breaking down and re-using materials that would otherwise be thrown away as trash. Many communities and businesses make it easy to recycle by placing labeled containers in the open for public use, or providing bins for home and business owners who have curbside pickup. There are numerous benefits to waste recycling and reuse with so many new technologies making even more materials waste recyclable and reuse, with everyone’s help we can clean up our Earth. Waste recycling and reuse not only benefits the environment but also have a positive effect on the economy. Waste recycling and reuse is reported throughout human history but has come a long way since the time of Plato when humans re-used broken tools and pottery when materials were scarce. Today, there is a multitude of benefits that come from recycling as well as tons of items that can be recycled. The different types of recycling are Waste Paper Recycling, Cardboard Recycling, Plastic Recycling, Metal Recycling, Wood Recycling, Textiles Recycling, Bricks/Inert Waste Recycling and Glass Recycling. In the light of the above study it is concluded that waste recycling and reuse is the major industry for the reproduction, absorbing millions of technical and non-technical peoples, generate income, create employment, stronger economy, reduce crises, poverty and hunger in the world.

Title: Co, Li, Cu and Al recovery from the stream of spent galvanic cells of the second lithium-ion type with methods of chemical metallurgy
Biography:
Amelia Zielinska has done research for PhD at Wroclaw University of Science and Technology. She is the director of Laboratory of Chemical Examination of Water. Her research interests focus on thermal e-waste treatment and hazardous waste recycling.
Abstract:
Chemical lithium-ion (Li-ion) energy sources dominate the market for second-class batteries (accumulators), almost all mobile phones and portable computers are powered by lithium cells. In addition, a new branch of the industry that generates demand for Li-ion batteries is the growing market for electric and hybrid cars. Lithium-ion batteries contain a number of valuable metals, such as Co, Li, Cu and Al. Cobalt is one of the less frequent metals in the Earth's crust, hence its market value is high - 80,490 $ / MT, and profitable recovery. Lithium recovery will be important in the perspective of the development of electric car production - the current price of 16 500 $ / MT. Mass production of vehicles powered by Li-ion batteries will increase the demand for lithium, so its price will increase and the recovery will be profitable. Another argument in favor of recycling batteries is the need to protect the environment against heavy metal pollution or complex organic substances in their composition.
The presented work presents the results of tests for the recovery of Co, Li, Cu and Al metals by chemical metallurgy using a mixture of formic acid, glutaric acid and perhydrol as leaching agents and sodium hydroxide as a precipitating agent. The conducted research led to the recovery of metals at a level above 85%.

Abstract:
Solid waste management is a public health threat as globalization of transport, food production, and commodity exchange have increased related environmental impacts and health risks. This review compared strategies and practices across countries against the 3R (reduce, reuse, recycle) and the modified integrated sustainable solid waste management frameworks, to identify countries with good models, and aspects for improved interventions. Most countries exhibited high waste generation, incineration, and landfill disposal, indicating failure in sustainable waste management. Waste management in industrialized countries depend on technologies, economic tools, and regulatory frameworks rather than social awareness of benefits and hazards, which could reduce resource consumption. In developed countries, compliance to waste separation and recycling is a response to regulations (taxes, fines, incentives), social pressure awareness (communities, peers, friends), and stakeholder inclusion and participation, rather than material values. Waste management systems across countries mainly operate within urban centres, with very limited services in rural environments. In most developing countries, informal stakeholders’ inclusion in waste management systems are successful due to economic benefits from the retrieved recyclable materials. Waste management improvements are reported in developing countries; however, substantial economic constraints, minimal incentives, partial stakeholder inclusion and participation, and limited awareness on hazards continue to pose challenges. Waste generation in most developing countries is predicted to double by 2025, and likely to result in greater environmental impacts and health risks. Chemical waste management and risk assessment frameworks, urgent and enhanced stakeholders’ awareness, involvement, partnerships, and participation in waste decision-making processes (design to implementation) will reduce adverse effects and risks across countries.

Title: New System of Solid Municipal Waste Management in Russian Federation
Biography:
Valery S. Petrosyan passed his PhD examination at Department of Chemistry of M.V. Lomonosov University at the age of 25, has been for the postgraduate research at Caltech (Pasadena, California) at the age of 35 and passed his D.Sc. examination at Department of Chemistry of M.V. Lomonosov University at the age of 37. He is now deputy general director for R&D at JSC “RT-Invest”, Distinguished professor at Department of Chemistry of M.V. Lomonosov University and Vice-President of Russian academy of natural sciences. He has published more than 500 papers in reputed journals and has been serving as an editorial board member of repute.
Abstract:
In 2018 it has been decided in Russian Federation to launch the Federal program, within the frames of which starting from January 2019 the new system of Solid Municipal Waste (SMW) Management should operate in Russia, which will create the modern scientific base and particular enterprises, which will allow Russian Federation to come up on the level of the countries, pioneering in this field. In this report we will report shortly, how this new system will operate. It includes several stages. First of all, the separate collection of SMW by population: one part – dry (paper, cardboard, plastics, glass, metals), second part – humid (food and vegetation residues). These two types of waste the population will collect separately in two types of different containers, which will be installed close to the living areas. The containers will be supplied with special sensors, which will inform specialists, responsible for SMW logistic, about the fulfillment of the containers. The second stage – the separate logistic of SMW, separately collected by population, to the complex centers for professional extra sorting of waste. According to the first data the educated workers collect 60 to 80% of useful fractions of dry waste and 5% of humid waste. At the third stage the separate logistic of extra sorted MSW to the enterprises of recycling separated dry waste into secondary resources is performed. Humid organic waste will be recycled into compost and, partly, into electricity. The modern enterprises for composting and four Japanese-Swiss plants according to “Hitachi-Zosen-Inova” technology for high temperature recycling of waste into electricity are nowadays under construction in the Moscow region. This type of MSW recycling has been widely used during the last decade in the most developed countries around the world. More than 500 of such plants are effectively used in Europe, Japan, China, USA, Canada, Brazil, Australia and many others. More than 150 of such plants are in the process of building in other countries. Those plants are safe according to to the analytical data for the composition of gases, emitted from the plants. This is why these plants are built even within the borderlines of big megapolises. We hope, that due to the new system of MSW management we will achieve our goals.

Abstract:
This study was conducted to correctly manage the system of storage, collection and transfer of wastes in district 22, Tehran. After reviewing existing methods, an optimal system was designed in the GIS environment and appropriate solutions were suggested. Analytical Hierarchy Process (AHP) method was used. After extracting result criteria, these criteria were provided to 15 experts and managers by means of a Delphi questionnaire. Screening of the criteria was done using the criterion importance graph; a necessary condition to apply criteria and sub-criteria, is having at least half the numerical value of each vertical and horizontal vector. The results of the study showed that the most important criterion associated with the selection of waste transfer station is "distance from residential houses" with a final weight of 0.341. "Suitable traffic conditions" and "lack of noise pollution" are the next important criteria with weights of 0.259 and 0.118, respectively. Finally, "non-destruction of recreational facilities" was chosen as the least important (weight of 0.03). Transfer in this district is also 100% mechanized. At the district level, there are 10 garbage trucks, of which 7 collect during night and 3 during day. Given per capita of the district, it takes about 10 minutes to collect each ton of waste. In general, in order to investigate and plan specific methods in the study district, using Geographic Information System, the location of reservoirs in residential and commercial districts has been determined and suggested with a coefficient of 0.75.

Title: Pyrohydrolysis of CaCl2 Waste for the Recovery of HCl Acid upon the Synergistic Effects from MgCl2 and Silica
Biography:
Song Zhou is a PhD student in Monash University, and a member of Clean Solid Fuel Laboratory (CSFL). His present research interest is mainly chloride waste treatment and atomic structure analysis based on X-ray adsorption fine spectroscopy (XAFS) analysis.
Abstract:
In this paper, an efficient HCl acid recovery method from the mixture of alkaline earth metal chlorides waste was demonstrated via co-pyrohydrolysis in a lab-scale horizontal furnace at a temperature range of 700–1000 °C, and fixed additions of SiO2 and steam. The synergistic effect of MgCl2 on the HCl recovery from CaCl2 was explored intensively. A double-sided effect was revealed. For the reaction temperatures below 1000 °C, the MgCl2 addition delayed the HCl release through competing with CaCl2 for the inclusion into silica matrix. In contrast, once the chloride mixtures were subjected to 1000 °C with a noticeable residence time (e.g. 2 h) and at a minimum molar ratio of 0.5 of MgCl2 to CaCl2, the MgCl2 addition promoted the HCl release remarkably, via promoting the conversion of Ca3(SiO4)Cl2 into Ca8Mg(SiO4)4Cl2. A portion of Mg2+ derived from the early decomposition of MgCl2 substituted the Ca(I) site in Ca3(SiO4)Cl2, thereby resulting in the formation of weak Mg-Cl bond that is in favour of the HCl release. Additionally, the remaining Mg2+ consumed the excessive SiO2 so as to cause the skeleton of [SiO4]4- to be fully affiliated and balanced by cations to form Ca8Mg(SiO4)4Cl2, in which the weaker ionic polarisation between Ca2+ and adjacent anions further enhanced the breakage of the Ca-Cl bonds.

Abstract:
Water shortage has been a major problem for most countries due to the limited amount of fresh water in the world. Over the few years, most research had focused on technologies such as reverse osmosis, electro dialysis, ultra violet radiation, constructed wetlands, microbial fuel cell, Nano and thermal filtration and other systems, for the treatment of waste water, and desalination of brackish water or sea water. Microbial Desalination Cell (MDC), due to its high efficacy, has offered significant advantages over the techniques currently used for seawater desalination, waste water treatment and energy production, which require enormous pressure to operate, and use up huge amounts of energy. The proof-of-principle of MDC system removes a high percentage of the salt from a seawater-like solution, treat waste water and produces energy simultaneously. A search of database sites such as PUBMED, Google Scholar, SCI-Hub, and Web of Science as well as other sources of literature available across public libraries was conducted to obtain relevant information related to the topic. This research presents the novel components and types of MDC systems. Also, it tackles the most contemporary advances and research in MDC, their applications and challenges. It then examines the future prospects of MDC at the commercial and industrial level which seeks to enlighten scientists and other stakeholders on waste water treatment, energy production and its related challenges.

Abstract:
Chicken feathers are the largest bio-waste produced across the world. Available uncontrolled disposal methods are not ecofriendly. Chicken feathers consists of about 91% Keratin protein. Keratin is a cysteine-rich structural proteins with unique characteristics of bioactivity, biocompatibility, biodegradability, and natural abundance. Protein component contain a defined three dimensional microstructure that aids in cellular proliferation and cell guided tissue formation. Genistein is a secondary metabolite isoflavones found in soybean. Genistein protects human dermal ï¬broblasts from oxidative stress-induced collagen biosynthesis inhibition thus acting as a epidermal growth factor. In this research Keratin was extracted, purified and charcterized to used in wound helaing hydrogel containig Genistein. Purified Keratin was tested for confirmational analysis by FTIR, SEM, SDS-PAGE, Amino acid profiling. Extracted Keratin was found to retain all the characterisitic values with reference standard. The formulated product was then tested for efficacy by in-vivo wound healing activity and saftey. The optimized wound healing formulation of Keratin - Genistein gel showed effective results of gel strength, pH, viscosity, spreadibility, drug contents. HPTLC study shows presence of both components in the gel without any interactions. Stability study indicates that the formulation was fairly stable. The results of in-vivo study indicated that feather keratin hydrogel significantly accelerated the wound healing compared to untreated group. Organ toxicity study revels safety of developed combination product.
