Sinkco Labs is a climate/biotech startup that uses the ocean to permanently store carbon while producing carbon-negative ingredients for consumer supply chains. We mimic seafloor conditions that prevent biomass decay—short oxygen exposure and compaction—bypassing the water column to avoid ecological impacts. Our patent-pending micro-injections use off-the-shelf parts and existing infrastructure to scale quickly, with an estimated 0.07 emissions-to-removals ratio.
