Residual waste management in London, England: a reality check

Area of Science:

• Waste Management
• Circular Economy
• Environmental Policy

Background:

• Residual waste management is poorly understood and lacks attention.
• The UK's progress towards circular economy principles needs assessment.
• London's residual waste data provides a case study for national evaluation.

Purpose of the Study:

• To analyze residual waste management in London.
• To assess UK progress on circular economy principles.
• To identify challenges and opportunities in residual waste handling.

Main Methods:

• Analysis of residual waste amounts collected and managed in London.
• Examination of disposal and recovery operations.
• Identification of data limitations and technological lock-ins.

Main Results:

• London manages 5 Mt of residual waste annually.
• 3.5 Mt is managed via recovery (1.44 Mt incineration), 1.59 Mt via disposal (0.82 Mt landfill).
• Technological lock-in and data blind spots hinder circular economy goals and net-zero ambitions.

Conclusions:

• Current residual waste management practices in London show a technological lock-in, primarily favoring incineration, which may impede the UK's net-zero targets.
• Data transparency and improved waste segregation at source are crucial for effective residual waste management and transitioning to a circular economy.
• Policy direction is imperative to address blind spots in waste data and promote sustainable residual waste management.
