Eco-Friendly Frontiers: Exploring the Green and Bio Polyols Industry

Green and bio-based polyols are ingredients used in the manufacture of polyurethane, a flexible polymer with applications in a variety of industries such as building, automotive, and furniture. Polyols are a major component in the manufacture of polyurethane, and they combine with isocyanates to generate the polymer.

The terms "green" and "bio-based" relate to the environmental friendliness and sustainability of these polyols. Traditional polyols are frequently obtained from non-renewable petrochemical sources, which contribute to environmental concerns. Green and bio-based polyols, on the other hand, are derived from renewable resources such as plants, biomass, or waste products and are regarded more environmentally benign.

The global green and bio polyols market size was 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 2022 and 2027.

Several types of green and bio-based polyols exist, and they can be categorized based on their raw material sources. Common sources include:

1. Vegetable Oils: Polyols can be derived from natural oils such as soybean oil, castor oil, or palm oil. These oils undergo a chemical process called transesterification to produce polyols suitable for polyurethane production.
2. Biomass: Some polyols are derived from biomass feedstocks, which can include agricultural residues, wood, or other plant-based materials.
3. Recycled Materials: Polyols can also be produced from recycled polyurethane or other waste materials, contributing to the circular economy and reducing the environmental impact.

"Natural oils and their derivatives is the largest raw material segment"

Based on raw materials, the green and bio-polyols market includes natural oils and their derivatives, sucrose, glycerin, and carbon dioxide. The natural oils and their derivatives raw material segment led the application segment of the market in terms of both value and volume. Bio-polyols made from natural oils are also known as natural oil polyols. These polyols can be made from soybean oil, rapeseed (canola) oil, palm oil, castor oil, and sunflower oil. The usage of a specific natural oil can be dependent on the region. All the natural oil polyols have similar sources and applications, but the materials are quite different, depending on how they are made. These polyols are colorless to light yellow. The viscosity of these polyols can vary based on the raw materials; it is determined by their molecular weight and the average number of hydroxyl groups present per molecule. The odor of these polyols varies based on the oil from which they are derived. Most natural oil polyols are quite similar chemically to their parent vegetable oils and are prone to rancidity.

'Polyether polyols are the largest applications segment"

Based on type, the green and bio-polyols market is divided into polyether polyols and polyester polyols. The polyether polyols type segment accounted for the largest share in the green and bio polyols market in 2021. Polyether polyols are generally produced by the catalysis reaction of epoxides. They are mainly used in the manufacturing of PU flexible foam. Polyether polyols contain multiple ether linkages and hydroxyl groups in their molecular form. Most of these polyols are used for manufacturing urethanes, surface-active agents, functional fluids, and synthetic lubricants. The physical properties of polyether polyols depend on the length of the polymer chain. These polyols have a molecular weight of more than 3,000.

"PU flexible foams is the largest applications segment"

Based on applications, the green and bio polyols market is divided into PU Flexible Foam, CASE, PU Rigid Foam. The PU flexible foams application segment accounted for the largest share in the green and bio polyols market in 2021. PU flexible foams are used in different consumer and commercial products, including furniture, carpet cushions, transportation, bedding, packaging, textiles, and fibers. These foams consist of slab stock, which is primarily used for carpet cushions and furniture. They are also used for office chairs, stadium seating, and auditorium seating. As a cushioning material, these foams provide support, comfort, durability, and energy absorption. PU flexible foams have a wide range of applications in the automotive industry, such as in seating, headrests, arms rests; heating, ventilating, and air conditioning (HVAC) components, interior panels & skins, car & truck fenders, headliners, and other interior systems. The use of polyurethane for automotive design results in weight reduction, passenger comfort, and compressive strength in vehicles, thus driving the need for polyurethane flexible foams in the automotive industry. 

"Furniture & bedding is the largest end-use industry segment"

Based on the end-use industry, the green and bio-polyols market is divided into furniture & bedding, construction, automotive, packaging, carpet backing, and others. The furniture & bedding end-use industry segment is the largest end-user of green and bio-polyols. Increased construction activities in the housing sector, especially in emerging economies, have fueled the demand for furniture & bedding products. Growing income levels in emerging markets have led to added expenditure on luxury commodities. The furniture & bedding industry is a rapidly growing market for green and bio polyols, which are being increasingly used to manufacture cushions for sofas, recliners, and upholstered chairs for both household and commercial purposes.
