Solid Waste Management

 

Challenges:

The majority of municipal solid waste ends

up in landfill. Anaerobic decomposition of

organics in landfill is a significant contributor

to global emissions of GHGs, including carbon

dioxide, methane, and nitrous oxide. Following

closure, landfills will continue to emit these gases

over hundreds of years. Leachates are also

released by rain, spreading to local land and waterways, thus compounding the

problems associated with landfills in terms of location and size. With the recognition of climate change as a critical global problem, concern has increasingly been directed to addressing the challenges associated with landfilling, as a major source of GHGs that are primarily linked to food waste generation and disposal. As global consumption continues to increase, the requirement for landfills continues to grow, leading to a guaranteed increase in future GHG emissions.

With the dramatic increase in usage of single-use face masks, there is a massive accumulation of a complex mixture of plastics, fibres and metals associate with their manufacture that needs to be addressed. This represents a hard to treat/recycle/reuse waste stream that requires a technology-based solution to address both environmental and public health challenges.

Our Capabilities:

  • Techno-economic and life cycle assessments of VAPs

  • Advice on the application of mineral-based composites for the capture and permanent sequestration of GHGs produced or emitted from landfills

  • Advice on the application of mineral-based composites for the reduction of odours produced or emitted from landfills

  • Advice for on-site production of soil conditioners for rehabilitation of closed landfills

  • Strategies for minimisation of leachates through encapsulation processes

  • Strategies for minimisation of discarded single-use face masks through encapsulation processes
