The global market size of green and bio-polyols is estimated at USD 4.4 billion in 2021 and is projected to reach USD 6.9 billion by 2027, at a CAGR of 9.5%, between the forecasted period. The growth of the global green and bio-polyols market is attributed to the strict government regulation prevalent in different parts of the world. The regulation against the extended use of polyols based on petroleum are a considerably significant issue for the government which can be suppressed by the use of green and bio polyols. The manufacturing of PU flexible or rigid foams is increasing. The demand of insulating materials in construction products, furniture & bedding industry, and the packaging industry is expected to fuel the positive growth of the green and bio-polyols market globally. The use of green and bio-based polyols in CASE applications is also a major growth factor for the market.
The green and the bio-polyols market is segmented into natural oils and their derivatives, sucrose, glycerin, and carbon dioxide based on raw materials. The natural oils and their derivatives raw material segment dominated the application segment of the market with respect to both value and volume. Natural oil polyols are the bio polyols which are made up of natural oils. Generally, these polyols are made from soybean oil, rapeseed (canola) oil, palm oil, castor oil, and sunflower oil. The usage of a different natural oil can be dependent on their availability in a particular region. Nearly all the natural oil based polyols have a similar origin/source and applications, however, there is a difference in materials that depends upon the manufacturing process involved in making them. Natural oils and their derivatives are colorless to light yellow. Their viscosity can differ depending upon the kind of raw material used.
The green and the bio-polyols market is segmented into polyether polyols and polyester polyols, based on type. The polyether polyols segment accounted for the largest share of the type segment of the green and bio-polyols market in 2021. Generally, polyether polyols are produced by the catalysis reaction of epoxides. Polyether polyols are found the best usage in the manufacturing of polyurethane flexible foam.
