University students in Leicester, England, are exploring the potential of genetically modified bacteria to create safer and more effective flame retardants, with a focus on improving the fire resistance of polystyrene products.
A group of undergraduate students from the University of Leicester has formed a team that recently participated in the International Genetically Engineered Machine (iGEM) competition, marking their second consecutive year competing at this prestigious event.
Their project aims to harness DNA as a novel flame-retardant material, specifically targeting expanded polystyrene (EPS), which is widely used in packaging and insulation. By engineering bacteria to produce higher quantities of DNA, the team hopes to develop a sustainable and cost-effective method for incorporating DNA into polystyrene to reduce its flammability.
In addition to creating non-flammable materials, the students are also working on a recycling initiative using DNA-based technology to repurpose polystyrene waste for 3D printing applications. This could help address the growing issue of plastic waste by turning it into a reusable resource.
The team also plans to further enhance their genetically modified bacteria to break down polystyrene more efficiently, making the recycling process even more eco-friendly. To engage the local community, they aim to collaborate with schools and continue the science experiments conducted last year, encouraging public interest in synthetic biology and sustainability.
