The Problem: 

While reducing production and improving recycling are crucial, we must address the legacy waste already choking our landfills and oceans.  

Millions of metric tons of plastic waste are dumped in landfills and marine environments each year, adding on to the already piled up dump yards. Meanwhile the traditional mechanical recycling struggles with contaminated, mixed, and low-value plastics, leaving this waste to persist for centuries. 

I am excited to share a concept I am exploring that sits at the intersection of synthetic biology, environmental science, and civic infrastructure: Landfill and Ocean Bio-remediation. 

The Proposed Solution: Targeted Bioremediation with Engineered microbial consortia. 

Recycling alone isn't cutting it. So, I’ve been obsessed with a question: Instead of fighting this waste with giant machines and trucks, what if we could work with nature? What if we could recruit an army of cleanup crews? 

The idea is to deploy tailored community of plastic-degrading bacteria and fungi directly into polluted sites. This isn't about using a single organism; it's about designing a synergistic microbial community—a precision tool for waste degradation. 

How it Works: 

We could design a multi-species community where each microbe has a specialized role: 

Primary Degraders: can be engineered to produce robust enzymes (e.g., PETase, MHETase) that breaks down complex polymers (PET, PP, PE) into simpler intermediates.

Secondary Consumers: Specialized to metabolize these intermediates which will prevent toxic buildup and complete the degradation cycle. 

Some strains could be further modified to convert waste carbon into beneficial byproducts, like organic fertilizers for land reclamation. 

For Biocontainment: 

To ensure environmental safety and prevent any bad consequences, we can integrate CRISPR-based gene drives to make these strains dependent on a synthetic nutrient not found in nature.  

This creates a built-in kill switch which will prevent uncontrolled replication outside the targeted cleanup zone.  

The goal: 

Imagine if our biggest trash piles could actually clean themselves. That's the idea: wake up landfills so they can break down plastic from the inside out. Less plastic means less poison seeping into our environment and a real chance to restore the land and ocean.
