Behavioural insight interventions, alongside traditional policy measures, offer promising solutions to nudge consumers away from single-use plastic consumption. This comprehensive Guidance Note shares practical lessons on the application of behavioural insights in four ASEAN countries: Indonesia, the Philippines, Thailand and Viet Nam. The...

Given the effort to reduce greenhouse gas (GHG) emissions, understanding the consumption patterns that facilitate and support changes is essential. In this context, household food consumption constitutes a large part of society’s environmental impacts due to the production and solid waste generation stages. Hence, we focus on applying the Life...

The report assesses the level of public awareness of microplastic pollution and related hazards as well as the current status of microplastic monitoring facilities available in Sri Lanka’s state and private sector institutes, with an emphasis on the public water supply chain and identifying microplastic point sources upstream to ensure safe...

The global demand for plastic is expected to double in the next 20 years. The increasing demand for Single-Use Plastic Products (SUPPs) has become one of the main environmental problems in many developing countries, including Sri Lanka, through direct and indirect means, in the way of excessive consumption and the pollution of the environment...

River meandering and anabranching have become major problems in many large rivers that carry significant amounts of sediment worldwide. The morphodynamics of these rivers are complex due to the temporal variation of flows. However, the availability of remote sensing data and geographic information systems (GISs) provides the opportunity to analyze...

The crisis ignited by COVID-19 has transformed the volume and composition of waste generation and requires a dynamic response from policy makers. This study selected Bangkok as a case study to semi-quantitatively examine the impact of the COVID-19 outbreak on consumer-generated food and plastic waste by examining changes in lifestyles and...

Ensuring sustainable consumption and production (SCP) patterns is an important task for achieving Sustainable Development Goal 12 by 2030. To facilitate international and domestic collaboration toward regional SCP, we developed a collaborative workshop method to generate and structure ideas about consumption and production (CP) patterns and...

This report presents the challenges faced and opportunities revealed through a study of two cases of source-segregated waste collection by local authorities in Sri Lanka; Moratuwa Municipal Council, in Colombo, and Kataragama Pradeshiya Sabha, in Monaragala for the purpose of raising planning and decision making capacities not only in Sri Lanka but...

This case study report examines the establishment and evolution of plastic waste recycling under two different operational modalities in urban areas of Sri Lanka; 1) single municipal operation, and 2) PPP (Public Private Partnership) based operation. This report provides an analysis of each modality in terms of effectiveness, technical feasibility...

This report presents three case studies in the context of centralised large-scale composting facilities in Sri Lanka in order to reveal the factors and approaches that led to positive results under different type of operational modality, i.e., 1) single municipal operation, 2) provincial operation, and 3) joint consortium operation (operated by two...
