Lifecycle Assessment (LCA) of FRP vs Traditional Materials
A full lifecycle assessment is essential when evaluating the true environmental impact of construction materials. FRP can deliver significant environmental benefits over its service life when compared with traditional materials such as steel, aluminium and concrete.
Overview
Material sustainability should not be judged only at the manufacturing stage. The full lifecycle needs to account for embodied energy, transport, maintenance, corrosion protection, replacement frequency and service life.
While the initial embodied energy of FRP can be comparable to, or slightly higher than, steel, the total lifecycle impact can be substantially lower because FRP typically requires less maintenance and can remain in service for extended periods with minimal degradation.
Initial embodied energy
45–90 MJ/kg
Typical range cited for FRP, depending on resin and fibre type.
Typical service life
50+ years
FRP can remain in service for decades with minimal degradation.
Steel maintenance cycle
5–10 years
Steel structures in corrosive environments may require recurring maintenance.
Why lifecycle assessment matters
Lifecycle assessment provides a more complete picture of environmental performance because it considers what happens after initial production. A material with a higher upfront energy requirement can still deliver a lower overall environmental impact if it lasts longer, requires less maintenance and avoids repeated replacement.
Lifecycle perspective
The key question is not only “What does this material cost environmentally to produce?” but also “How many times will it need to be maintained, coated, repaired or replaced during the life of the asset?
FRP lifecycle advantages
The white paper identifies several factors that contribute to FRP’s lower lifecycle impact:
Extended service life, often 50+ years with minimal degradation
Minimal maintenance requirements
No corrosion-related repainting or protective coatings
Reduced need for replacement and associated material production
These advantages are particularly relevant in harsh environments, where corrosion and ongoing maintenance can significantly increase the environmental and financial burden of traditional materials.
Maintenance and replacement cycles
Steel structures in corrosive environments may require maintenance every 5 to 10 years. Each maintenance cycle can involve labour, coatings, transport, equipment, shutdowns and new material inputs.
In contrast, FRP installations in marine, chemical and wastewater environments can remain maintenance-free for decades. This can reduce both emissions and resource consumption over the full life of the asset.
Application relevance
The lifecycle advantage of FRP becomes particularly significant in marine, chemical and wastewater applications, where corrosion exposure is high and access for ongoing maintenance may be difficult or costly.
Material comparison
| Factor | FRP | Traditional Materials |
|---|---|---|
| Service life | Often 50+ years with minimal degradation | Can be shorter in harsh or corrosive environments |
| Corrosion maintenance | Minimal or none | May require coatings, repainting and protection |
| Replacement frequency | Reduced due to durability | May require more frequent replacement depending on exposure |
| Lifecycle impact | Can be substantially lower over service life | Can increase through repeated maintenance and replacement |
Key takeaways
Evaluate the full lifecycle
Manufacturing impact is only one part of environmental performance.
Maintenance matters
Repainting, corrosion treatment and repeat repairs add to emissions and resource use.
Durability changes the equation
Longer service life can significantly lower total lifecycle impact.
Harsh environments strengthen the case
