“What a Waste 3.0” Highlights the Drivers of Resource Waste and Emissions

Dear team of WasteCulture
All in all the World Bank report provides useful data on various aspects of the global waste management.
In Section 5.1, they report:
"The highest amount of emissions (0f waste management) is associated with methane at 1.15 billion tonnes of carbon dioxide equivalent annually—applying a global warming potential (GWP) of methane of 27 from IPCC AR61."
I was curious how this 1,15 billion number compares with our EEC study where the estimated generation of methane from landfills is 0.05 ton methane per ton landfilled annually, that is:
=1 billion tons landfilled globally x 0.05 x 27 = 1.35 billion tons.
Fair agreement, considering that some of the CH4 generated in landfills is captured or flared.

Dear Werner P. Bauer,

Thank you for sharing your insights on the World Bank’s “What a Waste 3.0” report and its implications for global waste and emissions management.

I appreciate the emphasis on the systemic nature of the challenge, particularly the continued reliance on landfilling and open dumping, which remain major sources of methane emissions. The issue of underreported waste due to uncollected and informally disposed streams is also a critical gap in global waste data and accountability.

The proposed alignment with the waste hierarchy is important, but it is equally essential to situate this within a broader circular economy transition. Rather than focusing only on disposal improvement, the circular economy promotes reducing waste at source and keeping materials in use through:

1. Sustainable product design and durability
2. Reuse, repair, and refurbishment
3. High-value recycling and resource recovery
4. Organic waste composting and energy recovery

This approach shifts the system from a linear “take–make–dispose” model to a closed-loop system that minimizes waste generation and maximizes resource efficiency.

In contexts such as Kenya and other developing countries, circular economy strategies offer significant opportunities through waste valorisation, integration of the informal sector, and extended producer responsibility systems. These can reduce emissions while also creating green jobs and improving resource efficiency.

Your reminder that “you can only manage what you measure” remains fundamental, as effective circular systems depend on reliable data, material tracking, and lifecycle-based planning.

Overall, the key takeaway is that addressing the waste challenge requires not only better management of waste but a fundamental shift toward system redesign under circular economy principles.

Thank you once again for the valuable contribution.

Yours sincerely,

Mr. Jimmy Owiti.

Hello Waste Culture,
Having worked in the US waste sector for nearly 3 decades I have to disagree with the stated numbers with a focus on MSW 1) because they are not independently validated numbers but they are supplied by industry (haulers)/landfill companies 2) the dominant single bin recycling system in the US results in cross contamination and thus renders the majority of these 'recyclables' as useless. Many areas in the US use the ground up glass and paper for Alternative Daily Cover (ADS) to substitute for soil to cover the landfill and count it as 'recycling' 3) a vast majority of the organics are too contaminated with glass and plastics as well and it is common to mix sewage (they call it 'biosolids' for marketing purposes - see US wide discussions about PFAS - tip of the iceberg) into the 'compost' - creating a highly hazardous substance that no one should ever use for anything 4) there is a major reluctance to fixing the back end of the waste system in the US because a few people make a lot of money on Wall Street with waste at an enormous cost of externalities to the public 5)the actual recycling rate in the US is likely less than 10% for MSW and similar waste.
