Application

Design takeaway

Integrate the potential for repurposing spent adsorbents into the design process, moving towards a circular economy model for remediation technologies.

How to apply

When designing remediation systems, investigate the potential for the spent adsorbent material to be used in other industries or as a component in new products, rather than solely focusing on disposal.

Project actions

  • 01When selecting materials for a design project, research their potential for recycling or repurposing after use.
  • 02Consider the 'waste' stream of your design as a potential input for another process or product.

Paragraph starter

The research by Gwenzi et al. (2023) highlights that materials used for environmental remediation, such as spent adsorbents, often possess properties that allow for their repurposing into valuable resources. This perspective is critical for design projects aiming for sustainability, as it suggests moving beyond traditional disposal methods towards circular economy principles. By considering the potential secondary uses of materials, designers can reduce waste and create more resource-efficient solutions.
