Sustainable PU is in high demand due to several factors, including OEMs, converters, material suppliers, and customers. However, a limited supply of raw ingredients, high cost, relatively difficult processability, and performance criteria have hindered acceptance. Several startups and large polyurethane suppliers are creating recycled or bio-based substitutes for PU feedstock to overcome these issues.
Fremont, CA: More than 1,000 polymers are marketed commercially. A small number of materials, including polyesters, polyolefins, PVC, and polystyrene, nevertheless command a significant market share by volume. Sustainability studies have focused on polyurethane (PU), one of those materials. A number of factors drive sustainable PU research and its eventual commercialization.

PU has a strong presence in end markets through its many forms, including flexible, rigid, coatings, adhesives, sealants, elastomers (CASE), and others. It is generally recognized that the closer a material gets to end consumer markets, the more attention to sustainability it receives. Customers' purchasing habits are influenced by their awareness of environmental issues, which has sped up manufacturers' shift to raw materials and production methods that are thought to be more ecologically friendly and sustainable than alternatives.
Robust Growth in PUs
Despite having smaller volumes than other polymers, PU is a desirable investment option for a sustainable solution that the whole industry might embrace due to its about 7% yearly growth rate.
Multiple Routes to Sustainability
Polyols, the fundamental building blocks of PU, can be made from renewable resources or recycled materials. Polyurethane is being recycled to produce polyols combined with virgin polyols to create PU. Commercial polyols made from renewable resources, including plants, are also used to make PU foams and coatings for many other goods. Because both solutions are available, a two-pronged approach to achieving sustainability results. Although progress in the case of isocyanates has been gradual, it is anticipated that speed will pick up as research into the production of renewable aniline proceeds.

As the sustainability movement gains momentum, this tendency is anticipated to continue to grow across many application categories in the future.
