World of Algae
Exploring algae as a foundation for sustainable food, energy, water, materials, climate solutions, and economic development.
World of Algae represents the algae-focused origins of Sustainability In Action. The name was first used in commerce in 2010 in connection with algae-industry products, education, and sustainability information. This directory preserves that foundation while expanding access to current research, practical applications, organizations, technologies, and opportunities across the global algae sector.

Algae Fundamentals
Microalgae and macroalgae represent a diverse group of photosynthetic organisms found in marine, freshwater, and terrestrial environments. Understanding their biology, classification, and growth requirements is the essential first step in evaluating algae-based sustainability solutions.
Cultivation & Processing
Algae cultivation ranges from open-pond raceway systems to enclosed photobioreactors, each with distinct advantages for different species and end products. Harvesting, dewatering, and downstream processing technologies are critical for economic viability at commercial scale.
Food, Nutrition & Nutraceuticals
Algae have long been consumed as food, and their nutritional profile — rich in proteins, omega-3 fatty acids, vitamins, and antioxidants — positions them for expanded use in functional foods, dietary supplements, and novel protein sources.
Agriculture, Feed & Aquaculture
Algae-based feeds and agricultural inputs offer sustainable alternatives to conventional products. Biofertilizers, soil conditioners, and aquafeed ingredients derived from algae can reduce reliance on synthetic inputs while improving productivity.
Biofuels & Renewable Energy
Algae-based biofuels have been investigated for decades as a potential source of renewable liquid fuels. While commercial-scale production faces economic hurdles, ongoing research explores pathways for algae-derived biodiesel, biogas, renewable diesel, and jet fuel.
Carbon Capture & Climate Solutions
Algae are among the most efficient biological systems for carbon dioxide fixation. Integrating algae cultivation with industrial CO₂ sources offers potential pathways for emissions reduction, carbon utilization, and the co-production of valuable biomass.
Water Treatment & Bioremediation
Algae can remove nutrients, heavy metals, and organic pollutants from wastewater while producing biomass that may be converted into useful products. This dual benefit supports applications in municipal, industrial, and agricultural wastewater treatment.
Materials & Bioproducts
Beyond food and fuel, algae biomass yields a wide range of compounds for industrial applications. Bioplastics, pigments, cosmetics ingredients, pharmaceuticals, and specialty chemicals derived from algae represent growing market opportunities.
Companies, Suppliers & Projects
A global ecosystem of algae companies — from startups to established producers — spans cultivation technology, processing equipment, product manufacturing, and service provision. This section tracks commercial developments and industry initiatives.
Research, Education & Organizations
Universities, government laboratories, research consortia, nonprofit organizations, and professional associations drive algae science and technology development. Educational programs at all levels train the next generation of algae researchers and practitioners.
Where Sustainability In Action Began
Sustainability In Action began with a focus on the algae industry and the practical potential of algae-based products, technologies, education, and sustainable business solutions. World of Algae provided a platform for connecting scientific knowledge with cultivation, processing, commercial applications, workforce development, and public education.
That algae-focused foundation remains part of the organization's identity. World of Algae now continues within Sustainability In Action as a dedicated resource for examining established uses, emerging technologies, research, organizations, and real-world opportunities across the global algae sector.
