Seaweed Biorefineries Offer Significant Environmental Benefits for Circular Economies

Life cycle assessments of seaweed-based biorefineries reveal substantial environmental advantages, particularly in reducing greenhouse gas emissions and promoting circular economy principles.

RSC Sustainability · 2026

Key Findings

01Seaweed-based biorefineries generally demonstrate lower environmental impacts compared to conventional fossil-based alternatives, especially concerning greenhouse gas emissions.
02Key environmental hotspots often relate to energy consumption during processing, transportation of raw materials, and end-of-life management of by-products.
03Seaweed-derived products have significant potential to displace fossil-based materials and contribute to a circular bioeconomy through cascading use and waste valorization.

Application

Design takeaway

Integrate energy-efficient processing and comprehensive by-product utilization strategies when designing seaweed biorefinery systems to maximize environmental benefits and circularity.

How to apply

When designing or evaluating a biorefinery process, conduct a thorough life cycle assessment to identify environmental hotspots and prioritize mitigation strategies focused on energy efficiency and waste valorization.

Project actions

01When researching materials, consider the full life cycle impact, not just the initial production.
02Think about how all parts of a product or process can be reused or recycled.
