Sustainable food production technologies aim to meet 2050 demand

As the global population is projected to reach 9.7 billion by 2050, researchers and international organizations are exploring alternative methods to ensure food security with limited arable land. The United Nations estimates that global food demand could increase by approximately 60 percent by 2050, while available agricultural land is expected to grow by only about 2 percent.

One potential solution involves the use of microalgae. Produced in bioreactors, microalgae are nutrient-rich, space-efficient, and can be grown locally in urban environments. Beyond human consumption and dietary supplements, algae can be used to produce bioplastics, medical ingredients, and cosmetics. They also offer a sustainable alternative for animal feed, potentially reducing the reliance on resource-intensive fishmeal.

Additionally, researchers at the Technical University of Munich (TUM) have developed a process to produce essential amino acids using carbon dioxide, hydrogen, and renewable energy. By using solar power to create hydrogen and converting it with carbon dioxide into methanol, special enzymes can then transform the methanol into amino acids. This biotechnological approach aims to provide the protein building blocks required for livestock more resource-efficiently than traditional methods.
