An insightful discussion recently took place with Dr Amy Switzer, a molecular microbiologist and innovator in bio-plastics, offering a fascinating look into the future of bio-based materials. She explained how ongoing research, combined with collaboration from industrial partners, is leading to significant progress in the development of environmentally friendly plastics.
Dr Switzer has focused her career on microbial engineering and strain development, and she recently joined Biome Bioplastics, a company known for its work on bio-based chemical production for sustainable plastics. With over 15 years of experience in molecular microbiology, she brings a wealth of knowledge to her current role, where she is concentrating on creating monomers for bio-plastics through microbial fermentation. This pioneering work is essential in the push to replace traditional, fossil-based plastics with compostable and bio-based alternatives.
A primary hurdle in developing these bio-based compounds is balancing cost-effectiveness with enhanced performance when compared to conventional plastics. Dr Switzer acknowledges this challenge but believes that bio-based materials have the potential to become more economically viable at larger production scales. She noted that the cost might be lower when production reaches higher levels. However, she stressed that simply branding a product as “bio-based” doesn’t guarantee it will be environmentally beneficial. Conducting thorough life-cycle assessments is critical to determining the true environmental impact of these products, from their creation to their disposal.
Dr Switzer also addressed the common misunderstandings about bio-based materials, particularly the terms used to describe them. Many people are unaware of the differences between biodegradable, compostable, and recyclable products. This lack of understanding leads to confusion, with some believing that anything labeled “bio-based” is automatically better for the environment. She highlighted the need for clearer information to be shared with both consumers and industries, enabling a more responsible and informed use of these materials.
The discussion also covered the crucial role of government policy in promoting bio-based compounds. Dr Switzer emphasised that legislative support and incentives are essential to encourage industries to shift away from fossil-based plastics. Without these, many companies may lack the motivation to explore bio-based alternatives, even when they offer environmental and performance benefits. She pointed out that the pace of scientific advancements in bio-based materials has outstripped the development of corresponding legislation, but she remains hopeful that the two will eventually align.
Dr Switzer highlighted the importance of collaboration between academia, industry, and government in advancing the bio-plastics sector. Bridging the gap between research and practical application is vital for progress. She pointed out that a network of experts is needed to streamline the process of turning academic concepts into real-world products.
In her view, the work she is doing symbolises the growing relationship between biotechnology and sustainable materials. The progress being made in the production of bio-based compounds could significantly reduce the environmental damage caused by plastics. However, widespread adoption will depend on overcoming several barriers, including cost, performance, and consumer awareness, alongside supportive government policies. While the future of bio-based products looks promising, significant obstacles remain before they can completely replace fossil-based plastics in everyday life.
