In response to increasing concerns about the harmful effects of isocyanates used in the production of polyurethane foam, coatings, and adhesives, manufacturers in the global isocyanates market are shifting their focus toward bio-based alternatives. This shift is driven by a growing awareness of the hazards associated with isocyanates and a recognition of the benefits of using bio-based materials, such as those derived from vegetable oil.
To address these concerns, market players are adopting phosgene-free processes, aiming to minimize the adverse impact of isocyanates on human health and the environment. For example, Covestro AG has developed a bio-based MDI (methylene diphenyl diisocyanate) by utilizing aniline as a raw material. Aniline is derived from converting industrial sugar into a precursor through the use of microorganisms as catalysts, followed by chemical catalysis.
In 2015, Bayer AG introduced a bio-based hardener for polyurethane coatings and adhesives using pentamethylene diisocyanate (PDI). This development was a response to the growing demand for bio-based polyurethane coatings and adhesives on a global scale. PDI serves as a bio-based alternative to conventional toluene diisocyanate and hexamethylene diisocyanate, both derived from petrochemicals. The production of PDI involves starch and industrial crops, containing a substantial 70% of biomass-based carbon content.
Another notable development in this direction occurred in 2018 when Mitsui Chemicals, Inc. was honored with the Adhesion Society of Japan Technology Award for its achievement in creating plant-based pentamethylene diisocyanate. This recognition highlights the commitment of manufacturers to explore and implement plant-based alternatives in the isocyanates market.
In summary, the shift towards bio-based isocyanates is a response to environmental concerns and a desire to reduce the negative impact of traditional isocyanate production. By incorporating bio-based materials and adopting more sustainable processes, these manufacturers are contributing to a safer and more environmentally friendly industry.
