Thailand, like many countries around the world, is in the midst of a significant plastic waste crisis. In 2019, the government of Thailand released the Roadmap for Plastic Waste Management 2018-2030 and is developing the National action plan on Marine plastic debris to alleviate the current impacts and avert future damage caused by marine plastic debris. While these efforts are critical steps toward reining in the country's plastic pollution problem, further insight is needed into where the plastic waste comes from and how it moves in the environment. This study aims to better understand how plastic waste travels from land-based sources to marine environments by analyzing the material flow of plastic waste in five high-priority catchments. The study presents the first large-scale assessment in Thailand to integrate national waste generation and waste management performance data with actual hydrological conditions to estimate how mismanaged plastic waste is carried and discharged into the marine environment. This report is designed to assess how much mismanaged plastic waste (MPW) is flowing into the Gulf of Thailand. In Chapter 2, the approach and methodology are presented and explained, and the various definitions used in the report are discussed. The results of the models are presented in Chapter 3. The solid waste management model results are provided first, followed by the results from the fate and transport models. Chapter 4 provides the final conclusions and recommendations, which offer priority lists and examples of recommended measures to reduce marine debris.

Aims to support policy makers in their efforts to address plastic pollution. By examining the economic and financial implications of plastic management, the report provides key recommendations on how to create a comprehensive approach to addressing plastic pollution and to help policy makers make informed decisions for plastic pollution management. The report brings together new evidence from three analytical undertakings: -- Tackling Plastic Pollution: Toward Experience-Based Policy Guidance (a review of existing literature and a summary of findings from the ex post analysis of the effectiveness of plastics policies in 10 countries and states and an evidence-based policy guidance aimed at policy makers and stakeholders involved in design, implementation, and evaluation of policies to manage plastic pollution) -- The Plastic Substitution Tradeoff Estimator (an innovative model that estimates the external costs of 10 plastic products and their alternatives along their entire life cycle, developed and piloted in five countries. The Estimator can be applied in any country to identify what substitution materials, or what combination of them, would perform best in a given scenario and to examine tradeoffs between plastics and alternatives to help establish targets for reduction and substitution) -- The Plastic Policy Simulator (PPS) (a country-level, data-driven model for policy analysis to better describe the impacts of different policy instruments and policy packages on individual economic agents and on the plastic value chain at large. The PPS has been developed as a universal model and piloted in Indonesia. Its objective is to support policy makers and others in government, industry, and civil society in search of policy solutions to stem the flow of plastics by bringing an evidence-based approach to policy).

As global plastic waste continues to grow, the global community is coalescing to reduce plastic waste. Some stakeholders are also exploring new options to use plastic waste as partial substitute for raw material. The use of plastic waste as a bitumen modifier in road construction, referred to here as 'plastic roads', is one option being explored. We reviewed the scientific literature, news articles, and patents; conducted a cost-effectiveness analysis; and interviewed representatives from private companies and independent, scientific researchers to determine the existing knowledge gaps regarding the (1) technology feasibility, including engineering performance; (2) environmental issues; (3) occupational health; (4) economic viability; and (5) industry standards surrounding plastic roads. We found that many companies are starting to implement or pilot this technology worldwide though key gaps in engineering performance, such as cracking resistance, remain. The environmental issues reviewed also have research gaps, including the generation of hazardous air pollutants during production; microplastics and nanoplastics generation during use; and leaching of additives from plastic waste during use. Industry standards for the use of plastic waste in road construction are lacking. In addition, there is prevailing uncertainty in the economic viability of the technology. As a result of these key research gaps, the Ways Forward section presents a roadmap for short- and longterm research priorities.

Plastic is indispensable to modern life, so ubiquitous that it is virtually invisible. In many ways, it is an ideal material. Invented in the mid-19th century, plastic is remarkably versatile and relatively cheap to make, and it can be used as an inexpensive substitute for wood, glass, metal, and many other building and manufacturing materials. They play a vital role in driving industrial development, creating jobs, expanding opportunities, and generating wealth to improve people's lives. But as the use of plastic has increased, so too have the environmental and social costs. The production process uses petrochemicals as a raw material and generates greenhouse gas emissions. Perhaps the biggest cost is the waste generated by discarded plastic goods. Most of the common plastics of today are not fully biodegradable, and that has created a cascade of environmental, financial, and health problems around the world. Every year, eight million tons of discarded plastics make their way into the oceans. With enhanced recycling systems and better cooperation among industry, governments, and consumers, these plastics can be readily collected, reused, and turned into something of value. In the past dozen years, the plastics industry has been urged to rethink the material's entire lifecycle by developing manufacturing processes that use fewer natural resources, emit With support from the International Finance Corporation (IFC) and the private sector, the industry is embracing initiatives and investing in novel technologies that can reduce plastic's environmental footprint and provide broad economic benefits while meeting the growing demand for products made of plastic.

While plastics are extremely useful materials for modern society, plastics production and waste generation continue to increase with worsening environmental impacts despite international, national and local policy responses, as well as industry commitments. The urgent need to make the lifecycle of plastics more circular calls for an expansion of national policies and improved international co-operation to mitigate environmental impacts all along the value chain. The first of two reports, this Outlook intends to inform and support policy efforts to combat plastic leakage. The report quantifies the current production, use, disposal and key environmental impacts throughout the entire plastics lifecycle and identifies opportunities for reducing the negative externalities. It also investigates how plastics use and waste have been affected by the COVID-19 pandemic across sectors and regions. The Outlook identifies four key levers for bending the plastics curve: stronger support for recycled (secondary) plastics markets; policies to boost technological innovation in plastics; more ambitious domestic policy measures; and greater international co-operation.

The perennial presence of plastic waste in the Indus River and its tributaries is a recent addition to the already extensive list of threats to water quality, ecological health, and environmental sustainability in Pakistan. While there is some information available, although insufficient, both on surface water resources as well as on solid waste management (SWM) in Pakistan, the intersection of the two remains grossly under-studied in research circles and underrepresented on policy forums. This study delineates the interface between land based plastic waste and the Indus River system with the objective of raising plastics-in-rivers as a major policy and developmental issue, and providing a starting point for researchers, policy makers, and development and environmental professionals to expand the agenda of SWM to include protection of rivers. It is the first study of its kind in Pakistan and uses a combination of active sampling of floating waste at key sites in the Indus River system, passive sampling of waste dumped along the banks at those sites, consultations with key stakeholders in the sector, and a review of relevant policies, laws, and literature.
