    "inventor_name": "David Parker & Virginia Valentine-Cole",
    "publication_year": 2009,
    "device_name": "Cannabis Composter",
    "goal": "Provide low-cost, biologically based pest control in wastewater/compost while simultaneously producing valuable cannabinoids.",
    "problem_addressed": "Harmful insects, bacteria, fungi and other pests in sewage, wastewater, compost piles and disaster-site sludge; need for biodegradable, low-impact pest control and rapid toxin remediation.",
    "concept_summary": "The invention uses transgenic microbial or plant vectors (e.g., engineered E. coli, tobacco root hairs) that express a suite of enzymes to synthesize cannabinoid acids (THCA, CBGA, CBMA, etc.). These cannabinoids act as insect repellents, bactericides and fungicides. The vectors are equipped with bioluminescent/off-switch proteins for controllable expression. The system can be deployed in floating root-embedded platforms within wastewater, converting toxic sludge into enriched compost and producing cannabinoids that can be harvested or thermally converted to THC for neuroprotection.",
    "detailed_description": "The patent describes a modular, extensible genetic platform comprising several transgenic enzymes (TSCSL, TOAP, TCAs, TCBAs, TTAs, TCBMs) that together synthesize the full cannabinoid pathway from olivetolic acid to THC. Vectors are engineered to be motile in liquid media, allowing them to disperse throughout sewage or bilge water. A bioluminescent reporter and lethal \"off-switch\" enzymes provide containment and monitoring. Floating systems with root structures support the vectors, enabling continuous conversion of waste into nutrients and cannabinoids. In emergency scenarios, heat (sunlight or flame) can decarboxylate THCA to THC, which is claimed to offer neuroprotective effects.",
