Welcome to our community of trailblazers


Are you a built environment professional who sees the need to fight the plastic pollution crisis? 

Join us in our mission to reduce the use of plastic on a global scale. 

The manufacture and processing of plastic is carbon intensive. We need to address the link between plastic and achieving our net zero targets.​

Plastic is everywhere. After packaging, the construction industry is the biggest consumer of plastic in the UK.

According to the latest reports the growth in plastic production is expected to triple by 2050. Waste is also a serious concern, as we generate circa 50,000 tonnes of plastic packaging waste each year in the UK construction sector alone.

Community goals: 

  • To build a community of forward-thinking companies and individuals, focused on reducing plastic and embodied carbon in design and construction.​​​​ 
  • To bring like-minded people together from across the world with a common mission.​​​​ 
  • To establish a community space  dedicated to the exchange of , ideas, sharing of interests, and mutual support and learning​.
