Due to climate change, flood-related disasters are expected to increase. Floods generate enormous amounts of waste, including electronic waste (e-waste). E-waste should be recovered not only because it can have detrimental effects on human health and the environment but also because of the valuable metals contained in it. In this study, a system dynamics model based on current practices and waste management was established using Vensim to determine the revenue that can be generated by e-waste recycling after floods in two socio-geographic and economic contexts: Jakarta and New Orleans. At current recovery rates, the formal systems employed for recovering valuable materials would yield 8% (€58 million) and 14% (€80 million) of the potential yield for the Jakarta and New Orleans models, respectively. Moreover, the model estimated that informal e-waste recycling would yield €1.2 billion. The model also highlighted several problems encountered in post-disaster waste management in both scenarios, such as low capacities of temporary storage sites, increased landfilling rates, low yields of recovered e-waste components, and limitations on the transportation of waste. For optimizing the recovery of valuable metals, regulations addressing e-waste must be implemented more thoroughly, and post-disaster waste management guidelines must be revised to contextually address flood disasters. When more data are available, an improved model can be established and used as a basis for policymaking to improve the infrastructure of solid waste management to optimize e-waste recovery.

Communities store a potential power to support overall performance of urban solid waste management through various creative and innovative arrangements. In Indonesia, the Rukun Warga (RW) is the lowest hierarchy of community organizational system which can implement creative and innovative arrangements to support solid waste management activities with less financial requirement. This study observed RW-based activity on fifty RWs with 412 respondents in terms of 3Rs, household waste separation, waste recycling business and waste bank system undertaken by the community for the sake of cleanliness and income-earning. The result shows that the correlation between level of the activity of the RWs communities in undertaking 3Rs, recycling business and waste bank, and the perceived cleanliness by the community members was validated. It is also showed positive results such as improved urban environment and provided strong push-factor influencing the community members to join the movement and the activities towards sustainable solid waste management are not always cost-intensive activities but a socially bounded engagement would also workable.

Industrial Waste Management

Waste management in Tunisia is currently one of the priorities of environmental protection and is one of the main pillars of sustainable development. Thus, Tunisia has opted for a comprehensive and progressive policy of environmental protection in order to manage with the current state of the object affected by the strong economic growth and the environment rapid urban expansion in recent years. The area of ​​waste management has received attention currently given the quantity produced changes in the multiplicity of forms and aspects of pollution caused by waste, and limited resources used in the field of solid waste management. During this, our research has been devoted to the study of the phenomenon of industrial waste management by recycling in Tunisia. We employ a model based on a time series analysis model for a period of 17 years from 2000 to 2016. Additionally, we estimate the ability to manage industrial waste recycling based on variables related to the business of recycling industrial waste, variables related to the intervention of Tunisia policy in the management of industrial waste recycling and macroeconomic indicators. From the empirical findings, we conclude that the macro-economic indicators have a negative impact on the dependent variable. The variables related to the intervention of Tunisia policy in industrial waste management through recycling have a positive impact and a negative impact depending on the nature of the waste. And finally, the variable relative to the activity of recycling industrial waste TRDI has a positive impact and DIG variable has a negative impact.

Solid waste management is a grave concern for Bangladesh as by 2025 waste generation per capita will be 0.75 kg/capita/day and total amount of waste will reach 21.07 million tons per year. This chapter attempts to uncover the facts regarding waste management along with the policies and regulations existing in Bangladesh by reviewing published secondary documents. The chapter also contains emerging issues of agricultural, industrial, hazardous, construction, and electronic generation and 3R practices in Bangladesh. Legal instruments for waste management in Bangladesh are also examined. It has been found that enforcing authorities lack the capacity to implement their strategies regarding 3R practices for waste management. Case studies about community-based approach, waste recycling sector, and medical waste management have been exemplified in this chapter. Finally, the authors apprised the issues and challenges of sustainable solid waste management practices and proposed the way forward for Bangladesh to have sustainable solid waste management.

Abstract This study presents solid waste management planning in an urban green area, Bangkok, Thailand based on the material flow analysis (MFA) and life cycle assessment (LCA). Global warming potential (GWP) of four scenarios for handling solid waste generated in Chulalongkorn University Centenary Park, 2018 was assessed concerning the different ratios of waste recycling, composting, incineration, and landfilling. The results show that alternative systems proposed will result in lower GWP than the existing waste management strategy. The MFA results reveal that the final weights of solid waste ending up in a landfill are 98.8, 101.9, 68.2, and 44.8 t yr− 1 for scenarios 1, 2, 3, and 4, respectively. Increased rates of landfill diversion by increased recycling, composting, and incineration decreased the quantity of solid waste disposed to the landfill and improved the environmental profile of the park waste management system. The LCA results found landfilling to be the dominant source of greenhouse gas (GHG) burdens, while waste recycling was found to result in the reduction of GHG. The results highlight that the use of MFA and LCA as a combined tool to evaluate the environmental performance of solid waste management systems provides valuable information for policy and decision-makers.

High obsolescence rate and end-of-life of electronic equipment resulting in high generation of electronic waste remains the biggest challenge with use of ICT in higher institutions. This study evaluated and developed an environmentally sound E-waste management system for higher institutions in Rivers State. The study employed research surveys in data acquisition through questionnaires, interviews and observation. Hypotheses were postulated to test areas of interest. Study indicated that institutions generate a reasonably amount of electronic/ICT wastes that are poorly managed. Desktop computers, printers, laptops, UPSs, old CRT monitors, and printer cartridges are the majority generated and available E-waste in storage in these institutions. Results revealed that the level of awareness on hazardous nature of E-waste among the sampled population was significant. The level awareness on E-waste recycling among sampled population was also significant. There are no accurate records or inventory of ICT equipment procurement and E-waste generation and disposal in the institutions. Policies and programs on source reduction E-waste segregation and handling, facilities for E-waste recovery, recycling and reuse are practically not available in the institutions. The study concluded that there is no proper management and disposal of electronic/ICT waste in higher institutions in Rivers State. Significant numbers of respondents expressed the need for the institutions to establish an integrated electronic/ICT waste recycling center. An Integrated E-waste management system that will not only address the current poor E-waste management practices in the institutions but also achieve environmentally sound management of E-wastes in the institutions has been developed in the study.
