Circular economy and household e-waste management in India. Part II: A case study on informal e-waste collectors (Kabadiwalas) in India

Rapid advances in electronics and telecommunications technologies have contributed significantly to making e-waste one of the largest and fastest-growing solid waste streams. India produces over 3.23 million tonnes of e-waste each year. Over 90% of the total e-waste generated in the country is processed by the informal waste management sector. Informal waste collectors in India are known as ‘kabadiwalas’. Many people in India employ their services to discard household solid waste items, including e-waste. However, the percentage of people disposing of their e-waste to kabadiwalas is unknown. Moreover, detailed research studies on kabadiwalas’ waste collection activities are very limited to date. A case study was therefore formulated to determine the likelihood of e-waste disposal to kabadiwalas and their solid waste collection strategies, including e-waste fraction. A global positioning system (GPS) based real-time waste collection route tracking method was employed. The results indicated that many people in India (∼45% of survey respondents) prefer to dispose of their e-waste to kabadiwalas. Based on the GPS tracking results, the informal waste collectors were found to travel considerable distances using manual and modified three-wheeler vehicles (20–30 km per day) to collect household waste, out of which e-waste accounted for about 10%. It was deduced that their large workforce and low operating costs enable them to collect e-waste from households all over the country effectively. The results from this study indicate that kabadiwalas play an integral role in the e-waste management system of India and that their integration into the existing formal e-waste industry could help establish improved e-waste management and value recovery operations in India.

The strategy implemented is to improve the quality and competence of human resources for nurses and solid waste managers and improve the supporting infrastructure for medical and non-medical solid waste management.

Risks of Leukemia in Various Industrial Groups in Korea: A Retrospective National Cohort Study

It is known that occupational exposure to specific agents is associated with leukemia. However, whether the occupational risks of leukemia differ among various industrial groups remains unclear. Therefore, the purpose of this study was to elucidate the occupational risks of leukemia among different worker groups by industry. Data for a total of 11,050,398 people from the National Health Insurance System's claim data from 2007 to 2015 were analyzed. By cohort inclusion of workers whose industry had not changed for three years and with total workers as a control group, the risk for a specific industry group was expressed as an age-standardized incidence ratio (SIR). Among groups by industry, 'Manufacture of motor vehicles and engines for motor vehicles', 'Sale of motor vehicle parts and accessories', and 'Personal care services' showed significantly higher SIRs. In division analysis, the 'Manufacture of other machinery and equipment' and 'Waste collection, treatment and disposal activities' divisions showed significantly higher SIRs than other divisions. We identified an increased risk of leukemia in workers of certain industries in Korea. Based on the results of this study, it is necessary to create a policy to protect workers at risk of leukemia. Various additional studies are needed to protect workers by revealing more precise relationships between individual hazardous substances, processes, and leukemia.

Economic and environmental assessments of an integrated lithium-ion battery waste recycling supply chain: A hybrid simulation approach

This study aims to evaluate the lithium-ion batteries (LIBs) recycling process as a part of the supply chain network and assess its long-term economic and environmental impacts. A novel hybrid analysis incorporating agent-based, system dynamics, and metallurgical process analysis has been used to provide microscopic and macroscopic analyses of the integrated recycling system, which consists of waste collection facilities, transportation, and a waste recycling plant. The intersection between the supply chain and metallurgical process disciplines signifies this study's multidisciplinary nature. Mass balance calculation method and metallurgical process simulation software have been used to model physical and hydrometallurgy processing of the LIB waste within the recycling plant, respectively. The impacts of different LIB compositions and waste collection rate scenarios on economic and environmental performances have been evaluated. The results of the hybrid simulation show that selecting the type of LIB recycling process or technology must incorporate a thorough cost-benefit analysis since the recycling process' incentive depends on LIB composition and amount, operating cost, energy consumption, and waste outputs. The operating cost and waste outputs analyses must also cover LIB waste collection and transportation activities. This study offers valuable insights for LIB manufacturers, recycling companies, and the government in designing infrastructure for the electric vehicle's ecosystem.

Sector arc routing-based spatial decision support system for waste collection in Brazil.

We present a sector arc routing problem-based spatial decision support system technology to develop tactical and operational plans and manage solid waste collection activities including household refuse collection and human and mechanical street sweeping. The proposed technology can also manage solid waste services through optimization (minimizing sector costs, distances and resources). The proposed technology is called optimized planning and integrated logistics management. It can be directly applied to Brazilian municipalities as it contains its major natural features. The system uses advanced technics from sector arc routing and sector scheduling, fleet and staff scheduling and daily plan management using mobile smartphone apps. The technology also allows for waste system inspections that are transparent to all participants in real time. We present the results of cases evaluated in the field for residential refuse collection and human and mechanical street sweeping in two Brazilian cities (Campo Grande and São Paulo). The plan implementations achieved from 12 to 28% actual fixed and variable cost savings for sectors (vehicles and workers) and routes (time and distances) for residential refuse collection and from 7 to 42% savings for human and mechanical street sweeping for the companies.

A queuing system for inert construction waste management on a reverse logistics network

Many cities worldwide have built various types of facilities to manage the large amounts of construction waste generated year by year. One issue of great importance to the operational efficiency of these waste management facilities is the logistics management associated with waste collection and transportation activities. This research develops a queuing system to improve the management of inert construction waste (ICW). This system combines the queuing theory, a reverse logistics network (RLN) and a simulation function. The RLN integrates the sources of waste generation, the collecting and recycling facilities and the landfills, and the simulation function simulates the different processing capacities of the queuing system and the weekday and weekend operations of the facilities in the RLN. Multiple scenarios are considered in evaluating the effect of the queuing delays on the RLN to optimize ICW logistics management across the RLN. A comprehensive case study based on the practice of ICW management in Hong Kong further substantiates the utility of the proposed queuing system.

Application of Analytical Hierarchy Process (AHP) for Assessment of Collection and Transportation of Solid Waste: An Empirical Study

Cities and Urban Local Bodies (CULB) are considered to be the engines of economic growth and any significant improvement in their operational efficiency will lead to a positive impact on the economy. The major portion of expenditure on Solid waste management (SWM) of CULBs is spent on waste collection and transportation activities. To enhance the efficiency of SWM, it is essential to collect and transport solid waste in a scientific manner. As a result, systematic solid waste collection and transportation will effectively resolve and improve SWM concerns. In this paper, Analytical Hierarchy Process (AHP) method is adopted to appraise various alternatives of solid waste collection and transportation methods of municipal solid waste in Visakhapatnam city, India. The additive normalization method is applied for calculating the criteria weights. The fairness of judgment is checked by the consistency ratio. To calculate AHP accurately and fast, a decision support system was built. The findings of the study will be beneficial in evaluating existing solid waste collection and transportation processes to improve the operational efficiency of managing SWM.

Connectivity of vegetation diversity, carbon stock, and peat depth in peatland ecosystems

BACKGROUND AND OBJECTIVES: Prior to the COVID-19 pandemic, Hoi An City was one of the most famous tourist destinations in the world. This led to a rapid increase in solid waste generation, leading to problems and challenges in solid waste collection and management. This problem is also being experienced by other developing countries of the world. Despite the existence of established waste management strategies, targets set for the collection of recyclable waste have not been met. This study introduces solutions to the problems and challenges faced by the waste management sector in Hoi An city and other developing countries. This study aimed to i) optimize the map of the recovery recycling stations in an urban community, ii) develop an effective solid waste collection system, and iii) provide management tools to enhance recycling activities, contributing to improving waste management in Hoi An city.METHODS: The RRSs were integrated into a solid waste collection system in the urban communities of Hoi An City, were conducted through location-allocation analysis in a geographic information system environment. Routing problems of carts were solved in the combination of the rescheduling of existing solid waste collection activities in the study site. The economic evaluation by scenarios was also calculated for ten years to assess the feasibility of scenarios.FINDINGS: Thirty-four locations were identified and optimized to accommodate the RRSs and new collection routes. The distances travelled and working time increased in proportion to the increase in waste separation effectiveness. Waste separation is vital to the effectiveness of the new solid waste collection system.

LIFE CYCLE ASSESSMENT ANALYZING WITH GABI SOFTWARE FOR FOOD WASTE MANAGEMENT USING WINDROW AND HYBRID COMPOSTING TECHNOLOGIES

The use of composting technologies to treat food waste (FW) now represents an environmentally friendly form of waste treatment, in which organic matter can decompose biologically. However, the damaging emissions of composting technologies for FW treatment vary, thus a life cycle assessment (LCA) approach is often used to certify the quality of the decision-making process. This study quantifies and compares the environmental impact of two scenarios in Malaysia: windrow and hybrid composting (windrow integrated with a landfill) technologies. The scenario modeling was performed via GaBi v6.0 software using 1 ton of pre-treated FW as a functional unit, with the analysis based on the ReCiPe (H) v1.07 characterization method. The midpoint results revealed that windrow composting technology has a lower environmental impact and is an environmentally friendly option compared to hybrid technology. Treating FW in a windrow scenario has relatively low power requirements for operation with the added advantageous properties of compost production, and a substantial reduction in the distances transferred by the road. The hybrid scenario had the largest negative environmental impact in all categories, such as climate change (1.45E+03 kg CO2 eq), and ozone depletion (4.39E-09kg CFC-11 eq) because of the energy-intensive waste collection and treatment activities it needs, and with no landfill gas filtration. Finally, based on the single score synthesis, windrow is considered as an appropriate treatment with the avoidance of Resource Depletion (6.61E+02 Pt).

Solid Waste Collection System in Tourism Destination-The Status, Problems and Challenges

Solid waste collection system (SWCS) plays an extremely important role in solid waste management system (SWMS). Optimization on SWCS have always been a primary mission of SWM towards sustainability. Hoi An city (HAC) is a tourist attraction in the central of Vietnam with omnipresence of tourism activities especially in tourism destination (TD). As a result, optimization of SWCS towards sustainability is crucial for TD of HAC. This study aimed to offer understandings on the current SWCS. This study was conducted with GPS (Global Positioning System) logger and QGIS 3.4 to collect and analyze data of existing SWCS. Results showed that, four modes of transportation were used for solid waste collection activities (SWCA) with almost all of sources of WG in the morning. Largest figures for total number of route (29) and amount of waste collected by carts (19.6m3) were illustrated in the morning shift (MS). Illegal solid waste collection (SWC) accounted for about 10 % of total amount of waste collected by carts. Forklift trucks were the final disposal of all SWCA in TD. Current waste gathering (WG) practices indirectly damaged the tourism activities while the improper implementation of selective waste collection at source hindered the efficiency of SWCS in TD. This study made a contribution as a scientific base for optimization and administration of SWCS.

This study investigates future medical waste generation and greenhouse gas emissions resulting from medical waste collection and transportation activities in the city of Kocaeli, Turkey, between the years of 2020 and 2040. Population predictions were carried out by using Ilbank method, arithmetic method and United Nations Development (UNDP) method. Then, medical waste amounts were calculated based on the predicted populations. Among the three methods, arithmetic method was seemed to reflect the most reliable prediction. GHG emissions were calculated based on the fuel consumed by medical waste collection vehicles. The targeted GHGs were CH4 and CO2. Results of this work showed that the total medical waste generated per year was predicted to increase from 2,978 tons in 2020 to 5,203 tons in 2040. Finally, it was determined in this study that medical waste collection and transport would generate a total GHG emission of 11,229-ton CO2-e from 2020 to 2040. Furthermore, average global warming factor (GWF) was calculated as 0.00013 tCO2-e per ton of medical waste collected and transported. This study showed that medical waste collection and transportation generates significant amounts of GHG emissions. Results of this study will guide the local authorities when they plan to replace diesel fuel with alternative fuel types.
