Carbon negative biodegradable packaging materials
An innovative approach to creating biodegradable thermoplastics using engineered bacteria and microporous water, which uses CO2 as a feedstock. This solution aims to produce more flexible and tough bioplastics compared to current market options, potentially transforming carbon pollution into sustainable packaging.
Overview
This solution involves the development of biodegradable packaging materials using engineered bacteria that synthesize polyhydroxyalkanoates (PHA) from atmospheric CO2. The process leverages microporous water, which enables the concentration of CO2 to levels suitable for feeding the bacteria effectively. The resulting bioplastics are anticipated to be more flexible and durable than existing biodegradable plastics, offering a sustainable alternative for packaging needs and contributing to carbon negativity by utilizing CO2 emissions.
Technical specifications
Key features:
- Utilizes engineered bacteria to produce PHA bioplastics from atmospheric CO2
- Employs microporous water for efficient CO2 concentration and enhanced bacterial growth
- Potentially offers superior flexibility and toughness compared to current biodegradable plastics
- Process designed to minimize use of non-recyclable extraction reagents
Applications:
- Sustainable packaging materials
- Carbon-negative solutions for industrial use
Technology readiness level
The technology is currently at TRL 3, indicating experimental proof of concept has been achieved in a laboratory setting. Plans are in place to scale from 2L fermenters to bioreactors larger than 10L to further develop and optimize the production process. The research team anticipates further iterations on bacterial strain optimization, CO2 and mesoporous water concentration, and extraction processes to enhance output quality and scalability.
