How Green are Fibreglass Composites?

Let’s compare the Sustainability of Fibreglass Composites with old-fashioned materials like concrete and iron, for use in public spaces. That’s looking at things like trench covers, manhole covers, bridges, walkways and safety structures. 

Sustainability is often measured across three main aspects, these are: 

  • Socialthis includes items like safety, security and convenience,  
  • Environmental – things like energy consumption, emissions, waste, and virgin material use. This is what we call the ‘green footprint’.
  • Economicincludes purchase price, transport, life cycle, repair and maintenance costs and return on investment. 

Some things can cross over more than one category. For example, when we measure how sustainable composites are in relation to transport, they can fall under all three categories:

  • Economic (lighter weight = lower transport costs per unit)
  • Environmental (lighter weight = more efficient transportation, less equipment needed at installation, reduced traffic congestion due to quicker installation)
  • Social (lighter weight = easier to handle during transport = safety) 

There have already been several good studies that show how well Fibreglass Composites stack up against aluminium, concrete, iron and steel in terms of strength.

There hasn’t been much work done on how they compare for sustainability. A good study that looks at all three aspects of sustainability is ‘Bridge decks of fibre reinforced polymer (FRP): A sustainable solution.*  

We’ve also put together some information in a graphic you can access here Fibreglass Composites Green Footprint.pdf. We’re thrilled to report that Fibreglass Composites are more sustainable than concrete, iron, and steel. Composites get the tick of approval across all three categories including for their ‘green footprint’.
