Climate and Circular Economy

In this keynote, the speaker will address some of the key links between climate change mitigation and sound waste management towards a circular economy. ISWA has estimated that taking bold action on transitioning to a circular economy and improving waste management has the potential of mitigating around 20% of the global CO2 eq emissions.

ISWA Working Group on Landfills & Closing Dumpsites Task Force


(This is a 60 mins Session – Coffee break will exceptionally start at 15:40 in this room)


Panel Discussion: Transitioning from Dumpsite Operations into Integrated Sustainable Waste Management


Improper waste management has affected the health of people and the quality of our environment, whether it is directly or indirectly. In this session, we will discuss how closing or remediating dumpsites, and proper operating of waste infrastructure can conserve our ecosystems and enhance livability. In most parts of our world, it is the result of the choices we all make every day on doing something right or do nothing with our existing waste management and operation system. Since the projected volume of waste generation is on the rise globally and in line with projected population growth and urbanisation, any waste management system selected and utilised for a given region to operate successfully needs to be carefully evaluated and implemented for its efficiency and sustainability.


This session is presented by ISWA’s Task Force on Closing Dumpsites Global Initiative to highlight what we can do among the WGL members worldwide in assisting their dumpsites wanting to transition to a better and safer sanitary landfill operations, including adding features such as anaerobic digestor, composting operations, MBT, MRF, or gas collection system. There is a safe way to harness its green energy or renewal natural gas production and to reduce greenhouse gas emissions and carbon footprint at the same time in enhancing livability of the surrounding communities. To reduce the volume of waste going to the landfill, we need to divert as much organic waste and recyclable materials as possible away from the landfills.


Other hot topics such as landfill mining operations and reusing plastic waste from the waste stream will be discussed to show that landfills play a vital role as a final sink for materials that cannot be recycled or incinerated and also on how to transition from dumpsites to sanitary landfills operations. If executed properly and sorted materials have its final destination, landfill mining has a potential for recovering valuable resources and minimize the environmental risks from operating or remediating a dumpsite. A final fruit of thoughts is can we operate a landfill that is sustainable to achieve “zero waste” concept in a modern day’s material resources and waste management facility?

Coalition of Action against Marine Litter – Uniting Stakeholders for a sustainable future


Marine litter poses 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 Coalition of Action against Marine Litter. 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 “Coalition of Action against Marine Litter: Uniting Stakeholders for a Sustainable Future” 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 formation of partnerships and the exchange of knowledge, resources, and expertise among the participants.

Panel Discussion #2

Perspectives on the current regime development of international environmental discourse (consider including topics of informal sector- just transition and inclusion)

The triple planetary crisis declared by UNEP is creating awareness and even concern among citizens of the world. Chemicals and waste pollution as well as climate change are directly related to waste management and the circular economy. Action from institutions and companies is being demanded by civil society and this is only expected to grow. In this panel discussion, our distinguished panelists will discuss how the international environmental discourse around waste is evolving. A key aspect in the discussion will be the international treaty for plastics being negotiated. Also, 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.
