Asia-Pacific Spirulina Market (2025-2032)

Preservation of the environment has become a major concern. Continuous growth in the human population has increased petroleum consumption, with an ever-increasing demand for energy. According to the Global Energy Statistical Yearbook 2015, in Asia-Pacific, energy consumption is projected to grow by 31.2% between 2011 and 2021 due to growth in the human population. The extensive use of fossil fuels contributes to atmospheric CO₂ levels, the primary cause of global warming and climate change. If this environmental degradation continues, the planet will face catastrophic climate changes.

Spirulina cultivation helps diminish the greenhouse effect through CO₂ sequestration and abundant oxygen production. Spirulina cultivation using flue gas is more economical and environment-friendly. The cultivation of spirulina uses lesser space with a low impact on soil. In addition, spirulina is an excellent producer of oxygen. Large-scale production could, therefore, improve air quality.

Water and land use are two important environmental factors that must be considered. Interestingly, spirulina can be cultivated on arid lands. In addition, it needs a relatively lower amount of water, as water can be recycled after harvest. After extracting essential compounds from the biomass, the residual biomass can be used in many other refining processes. For instance, sugar-based and cellulosic biorefining can result in the accumulation of protein byproducts, which can be used as animal feed.

Spirulina cultivation can help combat pollution, water contamination and overconsumption, soil erosion, and deforestation. Additionally, after the extraction of essential compounds, the residual biomass can be used as energy feedstock for biodiesel production. Thus, integrated food and energy systems are designed to combine, intensify, and increase the productivity of food and energy simultaneously through sustainable land management. Food-energy integration makes spirulina more economically competitive with high diversification. Spirulina's large cultures play a vital role in rebalancing oxygen and CO2 levels and can effectively absorb toxins and heavy metals, making it an eco-friendly solution to address environmental issues.
