    Urban Waste Composition Associated to Online Food Delivery in Bangkok, Thailand, with Emphasis on Plastic Waste Management

    by Yanasinee Suma, Chongrak Polprasert, Numfon Eaktasang

    Growth of food online delivery to serve the modern life pattern of customer in urban. Plastic waste increased and had problems with waste management. The aim of this study is to investigate the urban waste composition related to online food delivery in Bangkok metropolitan, food delivery consumption behavior, and plastic waste generated from food delivery. Data from online food delivery customers were collected by online questionnaires from 385 participants. Proportion of plastic waste increased in municipal solid waste. Increase of order food delivery in online platforms about 76.6% of the total participants. The single-use plastic (SUP) generation related to online food delivery in household waste. Participants did not choose the green choices to decline the SUP when ordering food in platforms. These findings suggest reducing SUP from online food delivery, close-loop management requiring cooperation of producer-platform-customer-government. Extended producer responsibility (EPR) should apply for producers to make environmentally friendly products, online food delivery platform increase more incentive for merchants and customers to reduce SUP. Polluter-pay-principle (PPP) might be applied for customers. Government must adopt policy to ban SUP and design system for plastic waste management.

    Health impacts of faecal sludge management based on citywide inclusive sanitation in Bangkok city, Thailand

    by Suntorn Sudsandee, Thammarat Koottatep, Chongrak Polprasert

    Poor faecal sludge management (FSM) in developing countries are causing public health concerns. This study assesses the main factors of diarrheal infection in Bangkok city, focusing on CWIS factors and socio-economic aspects of the affected people from sanitation officials and households by using valid questionnaires. Collected data was analyzed by using Peason’ correlation, t -test, Chi -squared test, and univariable logistic regression analysis. The findings indicated a positive relationship between diarrheal cases and uncollected faecal sludge rates from HHs ( r = 0.47, p < 0.01) in Bangkok city was found in this research. Households (HH) experiencing leakage and overflow/high loading of contaminants from faecal sludge containments exhibited a prevalence of diarrhea 4.27 times (confidential interval (CI) 1.92–9.49) and 2.50 times (CI 1.33–4.69), respectively, higher than households whose containments had no leakage or overflow of containments. Additionally, households without faecal sludge emptying showed 2.25 times (CI 1.52–3.31) increased risk of diarrheal prevalences higher than households with faecal sludge emptying. The socio-economic data indicated households in high density areas had more diarrheal infections than those in low density areas. However, the difference in family incomes did not have significant effects on diarrheal infections, suggesting households in Bangkok city have adequate access to health education. The aforementioned data indicate the uncollected faecal sludge, and leakage or overflow of faecal sludge containments, and without faecal sludge emptying to be the main factors causing diarrheal infections in households in Bangkok city. Therefore, the Bangkok Metropolitan Administration (BMA) should increase the % faecal sludge collection from households by regular emptying services, using small faecal sludge collection trucks in high household density areas and periodic checking the performance of FS containments to prevent leakage and overflow of containments. In addition, Bangkok Metropolitan Administration should improve its accountability (AC) in faecal sludge management services, possibly by developing robust data/information management systems which should be accessible by stakeholders.

    Building a Resilient City through Sustainable Flood Risk Management: The Flood-Prone Area of Phra Nakhon Sri Ayutthaya, Thailand

    by Phichet Munpa, Atima Dubsok, Athit Phetrak, Wandee Sirichokchatchawan, Nutta Taneepanichskul, Jenyuk Lohwacharin, Suthirat Kittipongvises, Chongrak Polprasert

    Resilience has gained significant prominence in the management of climate-related shocks and the minimization of disaster risks. Assessing flood resilience is, therefore, crucial in identifying areas lacking support and opportunities for development. Comprehensive risk assessments are urgently required, especially in areas prone to floods. By applying the Analytical Hierarchy Process (AHP), stakeholder meetings, and keyword analysis, this study aims to assess the flood resilience of Phra Nakhon Sri Ayutthaya Province (PNSAP) in Thailand, an area at high risk of flooding and home to a UNESCO World Heritage Site. According to the Arup and Rockefeller Foundation’s City Resilience indicators, the key elements for building resilience in PNSAP include effective emergency response services, comprehensive hazard monitoring and risk assessment, and emergency medical care. In addition, the focus group discussions and keyword analysis identified the following critical components for strengthening flood resilience: “financial aspects”, “community awareness and preparedness”, “multi-stakeholder collaboration”, “citizen engagement”, and “urban flood monitoring and data management.” Moreover, to gain insight into the perceptions of people in local communities, the results of a household survey (n = 552) indicated that approximately one-third of the respondents had never engaged in flood preparedness activities. Neither the gender nor the education level of the respondents significantly influenced their engagement in flood preparedness. The respondents also perceived that infrastructure flexibility, affordable transport networks, flood monitoring and data management, the adequate provision of critical services, and reliable communication systems in building resilience were important during a flood disaster. These results provide valuable insight into the community’s perception of the effectiveness of disaster risk reduction mechanisms for building flood resilience in PNSAP and can serve as a useful guide for future resilience-building initiatives. By addressing these factors, PNSAP could enhance its resilience to the impacts of flooding and contribute to the global field of flood management and resilience building.

    Issues of Microplastics Pollution in Tap and Drinking Water Sources in Thailand and Health Impacts

    by Kesirine Jinda, Thammarat Koottatep, Warunsak Liamlaem, Chawalit Chaiwong, Tatchai Pussayanavin, Chongrak Polprasert

    The growing population with changing consumption patterns in developing countries is causing significant challenges with regards to solid waste management. Plastic wastes are particularly problematic, with single-use plastics leaking into the environment, including the marine environment, at an unprecedented rate. Approximately 80 percent of ocean plastics come from land-based sources or about 8 million tons are dumped into the ocean every year. Thailand was identified as one of the top 10 countries ranked by mass of mismanaged plastic wastes, with more than 60,000 tons per year entering the ocean through multiple outlets, including rivers. In the environment, plastic wastes can be degraded into small sizes (less than 5 mm), called microplastics (MPs), which could contaminate the ecosystems and the food chain, including foodstuffs and water supply. Tap water samples collected from a water supply treatment plant and Academic Institutions 1 and 2 in central Thailand were found to contain MPs about 304 ±90, 270 ±109 and 386 ±102 particles/L, respectively. In addition, MPs concentrations of 211 ±70 and 122 ±60 particles/L were also found in drinking water samples collected from commercial bottled water and membrane filtration water, respectively. The MPs sizes of 0-50 µm were most abundant in both the tap and drinking water samples whose shapes were mainly fragments and fiber. These data indicated potential health risks to the people who consume these water sources, and recommendations for health impacts minimization were proposed.

    Product design and development

    by Peter Emmanuel Cookey, Thammarat Koottatep, Walter Thomas Gibson, Chongrak Polprasert

    The value chain (VC) system is a key way to address important sanitation technological and institutional gaps in production and service delivery and could constitute a natural platform for development actions and also serve as a market systems approach to improve access to safely-managed sanitation. It has been suggested that sanitation could boost local and national economies and global interconnections with a growing recognition that the private sector can play a bigger role in delivering the Sustainable Development Goal for sanitation, and help businesses understand value-added and product opportunities. This book proposes a pathway towards re-thinking the sanitation value chain (SVC) and suggests that it should cover all processes, activities and products of enterprises/actors in the sanitation supply chain that provide value-added services within each stage. Following the Regenerative Sanitation Principles, this book presents a new perspective to the SVC known as the ‘integrated functional sanitation value chain’ (IFSVC) to address operational functions within sanitation systems in combination with sanitation enterprises, operators and external actors that support the growth of the sanitation economy. The underlying premise of this book is that the IFSVC represents a new perspective that would have major social, environmental and economic implications for local, national, regional and global sanitation service delivery. It is hoped that researchers, business leaders, entrepreneurs, government officials and funders will find this book valuable, and be inspired and enabled to carry sanitation work forward in their own spheres of operation. The book gives several examples of encouraging developments, particularly in technical and business model innovation. It is our hope that this book will provide the stimulus for new learning and its application, particularly through cross-disciplinary and cross-sector partnerships that bring together all the skills and capabilities needed to deliver a fully effective IFSVC.
