The Moment

The waste is a product of everyday human activities, and we are faced with large amounts of waste daily. Inadequate method of waste treatment effects are numerous: pollution of the environment and hazards to human health, the loss of useful components from waste, or the exploitation and consumption of natural resources. In the XXI century the sustainable management of municipal waste will become essential in all stages, from planning to construction, handling, recycling and final decomposition. Range of new and existing technologies for waste treatment and waste management strategies require the maintenance of environmental quality at the moment, but also the fulfillment of sustainability in the future.Integrated waste management should meet certain priorities in line with the waste hierarchy, such as requirements for recycling waste, to increase the use of renewable energy in order to looking for more socially acceptable options, and to preserve biodiversity and natural ecosystems simultaneously. Achieving these goals is possible only if all technical and non-technical aspects of solid waste management system are analyzed as a whole, because they are interrelated, and development in one area often influences the practice or activity in another area.Various analytical tools and methods are used to help in decision making in waste management systems. Analytical methods used in the waste management system can be classified into two groups: engineering models and models of assessment system.

Urban Solid Waste

Bangladesh is a low-lying riverine country. Unplanned growth of urban population causes audacious generation of solid wastes and strives immense pressure on existing services and environment. At present days, urban solid waste management is considered as most immediate and demanding environmental problems vexing Municipal authorities or urban governments in developing Asian countries like Bangladesh. Cities are now clashing with the serious problems of high amount of waste. The traditional concepts and inferior technologies of collecting waste are becoming incomplete as well as incompetent resulting more than half of the engendered solid wastes remain uncollected, disposed of regionally, forging the environmental view of cities quite murky and disheartening for the future. In waste management system, Germany is a role model for the world and the New German Closed-Cycle management is aiming to curve the waste management into resource management. The main intent of this research study is to categories in the solid wastes, discussing the issues of waste generation, a popular method for solid waste management, gasification schematic and waste-management model for Bangladesh. This study also explains Germany Closed-Cycle Management Act as well as waste treatment facilities, recovery, and disposal rate in Germany. Germany keeps very high-quality to preserve soil, air and water from the emissions integrated with waste storage and treatment.

Health service activities by the hospital produce a waste of any activity in the form of medical activities and non-medical activities. The purpose of this research is to analyze the solid waste management system in  'X' Hospital, Cilegon City, Banten. The result showed that the source of solid waste generated were classified into 2 types, namely 2% of medical waste and 98% non medical, where the waste treatment process included sorting, characteristic wastage, transporting garbage to TPS, weighing, temporary storage and transportation. The method of handling solid, B3 and domestic solid waste in 'X' Hospital is done in each unit which is sorting according to its characteristic, but still finding the placement of waste which is not in accordance with its characteristic and solid waste processing process is not done by the hospital but given to a third party. Therefore, it can be concluded that the effort to evaluate the solid waste management of 'X' Hospital must refer to the Decree of the Minister of Health of the Republic of Indonesia Number 1204 / Menkes/ SK / X / 2004 on Hospital Health Requirements and need to improve supervision and good cooperation with nurses and janitors in the separation of medical and non-medical waste.

Landfilling of organic waste is still the predominant waste management method in Canada. Data collection and analysis of the waste were done for the case study city of Montréal in Canada. A life cycle assessment was carried out for the current and proposed waste management system using the IWM-2 software. Using life cycle assessment results, a non-dominated sorting genetic algorithm was used to optimize the waste flows. The optimization showed that the current recovery ratio of organic waste of 23% in 2017 could be increased to 100% recovery of food waste. Also, recycling could be doubled, and landfilling halved. The objective functions were minimizing the total energy consumption and CO2eq emissions as well as the total cost in the waste management system. By using a three-objective optimization algorithm, the optimized waste flow for Montréal results in 2% of waste (14.7 kt) to anaerobic digestion (AD), 7% (66.3 kt) to compost, 32% (295 kt) to recycling, 1% (8.5 kt) to incineration, and 58% (543 kt) to landfill.

Solid waste management is one of the developmental challenges facing city authorities worldwide, especially in most developing countries. Rapid urbanization has made solid waste management a serious problem in poor and developing countries. This study aims to analyze the determinants of willingness to pay for improved solid waste management system. For this purpose, two hundred and seventeen Households were selected in Lekhnath, Kaski, Nepal. Pre-structured questionnaire was used to collect the data. Data was collected by using systematic random sampling techniques. Multiple Linear Regression analysis was used to find the determinants of willingness to pay for improved solid waste management system. The tentative average wastes produced per day from their house is one kilogram with minimum one hundred gram and maximum ten kilogram per day. Main disposal method/site for solid waste management of majority of the respondents is Burn followed by cannal, near open places, send in waste management vehicle, road side and rivulets. Almost all of the respondents are not satisfied with the community responsible for solid waste management in the study area. The average amount that the respondents have willingness to pay for solid waste management system is Rs 56.84 per month. Further, it is found that Having any member abroad, Remittance received in last one year and House ownership are the major determining factors for willingness to pay for improved solid waste management system in the study area. However, other factors like Sex of the respondents, age of the respondents, family size, Family type, Caste/ethnicity, education of the respondents, Total number of employed person at home, Total number of literate person at home, Major occupation of the respondents, tentative weight of accumulated solid waste per day, Monthly Income of household, Visit at any hotel/restaurant during last 12 months, and Having any livestock at household do not have any significant impact on willingness to pay for improved solid waste management system. Janapriya Journal of Interdisciplinary Studies, Vol. 6 (December 2017)

Due to enhanced healthcare needs brought upon by the COVID-19 pandemic, the amount of biomedical waste generated has also increased manifold across the globe. With the world in global crisis due to the recent outbreak of the COVID-19 pandemic, it has put great pressure on the biomedical waste management system in India and around the world. To control the spread of the COVID-19 virus, proper disposal of the waste is essential to reduce any risk of secondary transmission. This paper investigates the situation of biomedical waste management in the city of Thane in Maharashtra due to the onset of COVID-19 and suggests some key recommendations to the policymakers to help handle biomedical waste from possible future pandemics. The study found that there was an 81% increase in the total biomedical waste (BMW) generation in 2020, when compared to 2019 and the yellow category waste from COVID-19 centres was the highest contributor to this waste. It was also found that though there was a slight increase in yellow category waste, the total biomedical waste from non- COVID healthcare facilities (HCFs) was comparable to that of the waste generated in HCFs during 2019, revealing that there was conscious reduction in the usage of single use PPEs at non- COVID HCFs. The city, despite owning a Central Biomedical Waste Treatment Facility (CBWTF), was dependent on another incinerator at the Hazardous Waste Management Treatment facility (HWTF) for treatment of the additional waste generated. Unforeseen situation like these, expose the vulnerability of our existing biomedical waste management system and reinforces the need for investing and improving them for strengthening preparedness in the future. The situation also demands periodic education on importance of source segregation and waste reduction through rational use, disinfection and disposal of PPEs.
