Synthetic Biology and Biomanufacturing

Biomanufacturing uses genetically engineered microbes — bacteria, yeast, algae — as living factories. Instead of cracking petroleum into plastics and chemicals, engineered organisms convert sugar, CO2, or waste biomass into the same products with lower emissions.

China is scaling this from lab to industrial production. Applications include bio-based nylon, sustainable aviation fuel, lab-grown collagen for cosmetics, and engineered enzymes for industrial processes. The government's explicit inclusion of biomanufacturing in the Five-Year Plan signals infrastructure-level investment.

The bottleneck is cost competitiveness with petrochemicals. At current oil prices, bio-based alternatives are often 2-3x more expensive. China's strategy is to push down the cost curve through manufacturing scale — the same playbook that worked for solar panels and batteries.
