Climate and Circular Economy

The way in which the world uses physical materials has never been more important. Long-term prosperity will be impossible without achieving sustainable economies, including combating climate change, and more efficient use of physical resources. Recent years have seen high volatility, high prices and, in some cases, shortages of key materials, and how to make the most of material resources is at the center of the agenda from boardrooms to foreign ministries. Bold action in improving waste management would be a major contributor to solving these global problems.

ISWA Working Group on Landfills & Closing Dumpsites Task Force (60 mins session)

Panel Discussion: Leveraging dumpsite closure opportunities to transition to sustainable waste treatment and disposal solutions

This session is presented by ISWA WGL and IFC’s Task Force on Closing Dumpsites Global Initiative to highlight what we can do worldwide in assisting countries with dumpsite operations who want to reduce
waste mounding by bio-mining, sorted material reuse or converting to RDF product for green energy feedstock. To reduce the volume of waste going to the dumpsites, we need to divert as much organic waste and recyclable materials as possible away from the dumpsites. Bio-mining operations, recovering of RDF, and reusing plastic waste from the waste stream at dumpsites will be discussed to show how they are related and in transitioning from dumpsites to controlled or engineered sanitary landfills operations. If executed properly, and sorted materials have their destinations, bio-mining has a potential for recovering material resources, waste volume reduction, and minimizing the environmental risks from operating or remediating a dumpsite. Finally, the panelists will discuss how to finance dumpsite closure or remediation activities, along with its challenges in various parts of the world where regulations and
standard of practices vary significantly.

ISWA Working Group on Governance and Legal Issues

Sound governance instruments for waste management and their value towards a circular economy with multi-stakeholder cooperation and inclusion

Governance is crucial to establish sound waste management systems. Likewise, instruments and tools are very important to implement governance systems. When it comes to developing sound waste management and transitioning to a circular economy, the portfolio of potential approaches is varied and there are no one-size fits-all. In this session, the working group will present several topics such as EPR implementation in developing countries, integration of the informal sector towards an integrated waste management system and the importance of sound governance and enforcement at the national and municipal level. Join us to discuss lessons learned around the world on the mentioned issues and the future perspective that emerging instruments like the one being negotiated at INC could bring.

Focus Session 

Community of Action against Plastic Pollution – Focus on the Marine Environment


Plastic pollution and marine litter pose a significant threat to our oceans, ecosystems, and the overall health of our planet. Recognizing the urgency of  this issue, a diverse group of stakeholders and players are coming together to form a powerful Community of Action against Plastic Pollution – Focus on the Marine Environment. This coalition aims to leverage the collective knowledge, expertise, and resources of its members to drive tangible and sustainable solutions to address this global challenge.

The session “Community of Action against Plastic Pollution – Focus Session on Marine Environment “will invite participants to engage in a dynamic dialogue that explores the transformative potential of collaboration across sectors. The session will provide a platform for stakeholders from the private sector, governments, civil society organizations, scientific institutions, and international bodies to share their experiences, insights, and innovative approaches.

The objectives of this session are threefold: First, to foster an understanding of the multi-dimensional nature of marine litter and its impact on marine ecosystems, biodiversity, and human health. Second, to showcase successful case studies and initiatives implemented by various stakeholders, highlighting best practices and lessons learned. Lastly, to facilitate the exchange of knowledge, resources, tools and expertise among the participants. The session will feature engaging presentations from renowned experts and an interactive panel discussion to encourage meaningful dialogue and collaboration. By the end of the session, participants will have a clear understanding of the urgent need for collective action against marine litter and the diverse range of opportunities for collaboration. They will be invited to join the Community of Action, actively contribute to ongoing initiatives, and initiate new efforts in their respective domains.

In conclusion, the session will serve as a catalyst for transformative change, empowering stakeholders from different sectors to combine their efforts, knowledge, and resources. Together, we can build a future where our oceans thrive, free from the scourge of marine litter.

Panel Discussion #2

Shaping Global Environmental Discourse: High-Level Plenary on Triple Planetary Crisis, Inclusion, and a Just Transition in the Waste and Resource Management Sector

The world is facing a triple planetary crisis comprising climate change, biodiversity loss, and resource depletion. As we address these interconnected challenges, we must ensure that the transition towards sustainability is just, equitable, and inclusive. Action from institutions and companies is being demanded by civil society and this is only expected to grow. It is clearer than ever that a sensible waste and resource policy, no matter how modest, can make a world of difference in combating the triple planetary crisis. For some low-and-middle income countries there are other things that seem more important, but a good waste policy and a well-functioning waste management system pays for itself many times over. It is an investment in the future, in our children, in future generations. In this session, our distinguished panelists will discuss how the international environmental discourse around waste and resource management is evolving. This panel discussion aims to explore these intersecting themes. A key aspect in the discussion will be on how industry, society, and government institutions can react and act to attend to the demands and calls for action concerning the triple planetary crisis from the waste and resource management angle. The session will be moderated by Philip Heylen who will challenge the speakers to each come up with a concrete, tangible proposal, with which we can make the globe cleaner and greener in the short term.
