Waste management and recycling

Understanding Waste Management and Recycling

Overarching Concepts

  • Waste management in sustainable construction involves the smart usage and disposal of resources.
  • The aim is to minimise waste and maximise the re-use and recycling of materials.
  • An efficient waste management strategy considers the waste hierarchy: Reduce, Reuse, Recycle.

Types of Construction Waste

  • Masonry waste includes bricks, blocks and concrete that can often be reprocessed into aggregate material.
  • Metal waste like steel and aluminium are highly recyclable and often sold as scrap metal.
  • Wooden waste can be reused in other construction projects or used as biomass fuel.
  • Plasterboard waste is often landfilled but can be recycled into new plasterboard or used as a soil conditioner.

Processes and Techniques

  • Site Waste Management Plans (SWMP) is a tool that helps constructors reduce waste and increase recycling rates.
  • Just-in-time delivery can reduce waste by delivering materials only as they are needed, reducing the risk of damage or degradation.
  • Implementing recycling stations on-site provides a dedicated space to sort and store recyclable materials.
  • Off-site construction or pre-fabrication can lead to less waste as components are built in a controlled environment.

Benefits of Effective Waste Management

  • Managing waste effectively can lead to cost savings, as fewer resources are wasted and fees for landfill disposal are reduced.
  • Demonstrate corporate responsibility as businesses take steps to reduce their environmental impact.
  • Comply with legislation such as the Site Waste Management Plans Regulations 2008.
  • Achieve higher ratings in industry standards like BREEAM or LEED.

Challenges in Waste Management

  • Requires time and investment to plan and implement effective waste management strategies.
  • A construction site may lack adequate space for on-site recycling.
  • Collaboration and communication are key and all involved parties must be dedicated to waste reduction objectives.
  • Regulations around waste disposal and recycling can be complex and vary by area.
