The versatility of algae in addressing the global sustainability challenges.
Review in Frontiers in bioengineering and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Algae have developed into a sustainable and adaptable resource that can help with several global issues, such as resource depletion, environmental degradation, food security, climate change, and energy security. It explores the multifaceted potential of algae in addressing key global sustainability challenges-including climate change, resource depletion, environmental pollution, food insecurity, and energy demands-through biotechnological innovations. Chlorella, Nannochloropsis, Botryococcus, and Spirulina demonstrate exceptional efficiency in biomass production, carbon sequestration, nutrient recycling, and bioenergy generation. Objectives of this review include evaluating recent advances in algal-based wastewater remediation, biodiesel production, and circular bioeconomy strategies, with a focus on the integration of industrial waste streams like abattoir wastewater and crude glycerol. Notably, Chlorella sorokiniana has shown high potential for phycoremediation and biodiesel yield when cultivated in abattoir wastewater digestate (AWD), achieving up to 90% BBM replacement with enhanced lipid and carotenoid content. Similarly, the valorization of crude glycerol via microbial and insect-based systems underscores algae's role in supporting low-carbon bioeconomies. In agriculture, macroalgae such as Asparagopsis taxiformis have significantly reduced enteric methane emissions in livestock, highlighting their utility in climate-smart farming. Despite these advances, the scalability and economic viability of algal technologies remain constrained by high production costs, energy-intensive processing, contamination risks, and regulatory limitations-especially in food and feed sectors. It advocates for targeted research into cost reduction, process optimization, and harmonized policy frameworks to unlock algae's full potential. By addressing these challenges, algae can become central to sustainable development strategies, enabling effective transitions toward cleaner energy, healthier ecosystems, and resilient food systems.
