I propose a feedback-sustained bacterial system engineered to degrade plastic. The bacteria contain enzymes that break down plastic (e.g., PET) and convert it into byproducts such as ethylene glycol. The system uses this ethylene glycol to generate heat, and it includes a genetic circuit feedback loop that dynamically adjusts the temperature—raising or lowering it relative to the surroundings—to maintain an optimal reaction environment.

Why:

Plastic pollution is a severe global problem. For example, millions of tons of plastic waste and microplastics are contaminating the environment, affecting wildlife and human health. A cost-effective, passive, and low-maintenance solution is urgently needed to address this challenge.

Governance:

Ensure Safety – Containment and Control

Sub-goal 1: Establish a supply chain protocol that mandates the use of equipment made of glass and a special type of plastic that the bacteria cannot breach. Sub-goal 2: Restrict the deployment of the bacteria to enclosed, controlled environments, preventing their random use in open areas.

Ensure Environmental Protection

Sub-goal 1: Integrate a UV-activated kill switch that, upon exposure to a specific wavelength, damages the bacteria’s DNA and shuts down the system. Sub-goal 2: Regularly monitor all operational areas for any signs of containment breach or environmental impact.

Ensure Accountability

Sub-goal 1: Engineer a genetic barcode into the bacteria so that any accidental release can be traced back to its source. Sub-goal 2: Set up an oversight body and contractual agreements that hold responsible parties accountable if a breach occurs.
