THEME 10: ACHIEVING A CIRCULAR ECONOMY

 

The linear model of extraction, production, consumption and disposal has come to an end.  A circular economy is one that looks to minimise waste and make the most of resources.  Wastewater treatment plants will be resource recovery centres with the resources – water, carbon, nutrients, energy being recovered and returned to the community.  What action is being taken now to achieve a circular economy and where are we lacking? What policy, regulatory, governance and business model transformations are needed to drive a circular economy, and the water sector’s pivotal role in it?

  • Co-digestion and organic waste to energy  
  • Biomass: resource classification and use 
  • Contributions to the circular economy by the water industry
  • Water recycling 
  • Nutrient recovery – is there any gold to be recovered?
  • Biosolids use – from agricultural application to thermal destruction
  • Novel materials (bioplastics)
  • Energy recovery and waste to energy – we can do it but do the economics stack up?
  • Circular economy: what does it mean for communication, public and stakeholder engagement, and incentives?
  • New policies, business models and investment strategies
