Adipic acid is a key raw material for producing nylon 66, a versatile polymer that has applications in fibers, resins, and other products. However, conventional adipic acid production from petroleum-based feedstocks generates greenhouse gas emissions and consumes non-renewable resources. In recent years, several companies have developed bio-based routes to produce adipic acid from renewable sources, such as sugars derived from inedible biomass. These routes offer environmental and economic benefits, as well as the potential to create 100% bio-based nylon 66.

Biobased Adipic Acid Production Processes

There are different bio-based processes to produce adipic acid from sugars, but they generally involve two main steps: fermentation and purification. Fermentation is the process of converting sugars into organic acids or intermediates using microorganisms or enzymes. Purification is the process of separating and concentrating the desired product from the fermentation broth using chemical or physical methods.

Benefits of Biobased Adipic Acid

Bio-based adipic acid offers several benefits over conventional adipic acid, such as:

• Reducing greenhouse gas emissions: Bio-based adipic acid production can avoid the generation of dinitrogen monoxide, a potent greenhouse gas that is emitted during the nitric acid oxidation of cyclohexane. Moreover, bio-based adipic acid can use renewable feedstocks that have lower carbon footprints than fossil fuels.
• Saving non-renewable resources: Bio-based adipic acid production can reduce the dependence on petroleum-based feedstocks, which are finite and subject to price volatility. Bio-based adipic acid can use waste or residual biomass as feedstocks, which are abundant and low-cost.
• Creating 100% bio-based nylon 66: Bio-based adipic acid can be combined with bio-based hexamethylenediamine (HMDA), another raw material for nylon 66, to create 100% bio-based nylon 66. This would enhance the sustainability and biodegradability of nylon 66 products.

Challenges and Opportunities for Bio-Based Adipic Acid

Despite the benefits of bio-based adipic acid, there are also some challenges and opportunities for its development and commercialization, such as:

• Scaling up production: Bio-based adipic acid production requires large-scale fermentation and purification facilities that can ensure consistent quality and yield of the product. Scaling up production also requires securing stable and reliable sources of feedstocks and optimizing the process parameters.
• Meeting market demand: Bio-based adipic acid production needs to meet the market demand for nylon 66, which is estimated at 2.3 million metric tons in 2012 and growing at 3–5% per year. Bio-based adipic acid production also needs to compete with conventional adipic acid production in terms of price, performance, and availability.
• Developing applications: Bio-based adipic acid production needs to develop applications that can showcase the advantages of bio-based nylon 66 over conventional nylon 66. Bio-based nylon 66 can be used for various applications, such as apparel, automotive, engineering plastics, and packaging.

Conclusion

Bio-based adipic acid is a sustainable alternative for the chemical industry that can reduce environmental impacts and save non-renewable resources. Several companies have developed bio-based processes to produce adipic acid from sugars derived from inedible biomass. These processes offer the potential to create 100% bio-based nylon 66, a versatile polymer that has many applications. However, there are also challenges and opportunities for scaling up production, meeting market demand, and developing applications for bio-based adipic acid.
