1. A biogenic methane mitigation system comprising:
a floating island having two ends and being comprised of a biofilm-reactive matrix;
an airlift system on one or both ends of the floating island, the airlift system comprising one or more pipes or hoses and an aeration system;
wherein macro-and micro-treatment system bubbles are passed under and into the floating island, thereby exposing methane to active methanotroph culture and causing mitigation of the methane.
