Comparative Life Cycle Assessment highlights better recycling methods for decommissioned pipelines, indicating improved environmental outcomes.

The aim is to evaluate waste management options for decommissioned flexible pipelines in Brazil through comparative analysis.
Identified two routes for dismantling flexible pipelines.
Conducted a comparative life cycle assessment (LCA) of both routes.
Analyzed aspects like energy consumption, productivity, and occupational hazards for each route.
Route B enables mechanical recycling of 98% of polymeric material.
Route B shows 9.6% of the global warming impact compared to Route A.
Impacts of Route B range from 1.47% to 12.18% across different environmental categories compared to Route A.

Oliveira et al. (2026) studied this question.
