Competitive Landscape of the Bio-PG Market Worldwide
The rise of bio-based propylene glycol (PG) is closely linked to advancements in biotechnology and green chemistry. Traditionally derived from petroleum, PG is now increasingly produced from renewable feedstocks like glycerin, corn, and soy through innovative methods that prioritize efficiency and sustainability.
One breakthrough in bio-based PG production is the catalytic hydrogenolysis of glycerin, a byproduct of biodiesel production. This process converts glycerin into PG efficiently, creating value from a renewable feedstock that was once considered waste. It not only reduces dependence on fossil fuels but also supports circular economy principles by utilizing industrial byproducts.
Another promising method involves fermentation technologies that use microorganisms to convert carbohydrates into PG. This approach is gaining attention for its scalability and ability to utilize non-food biomass sources, reducing competition with food crops.
Advances in catalyst development have also improved conversion efficiency, lowering costs and enhancing yields. Researchers are focusing on heterogeneous catalysts that are more stable and recyclable, making the production process…
