The eruption of Fukuoku-Oka-no-Ba in 2021 has resulted in a vast amount of pumice washing up on the shores of Okinawa Island, causing severe damage to marine traffic, fisheries, and recreational activities. In response to this dire situation, we swiftly developed a handy plume skimming device, drawing upon our extensive knowledge base and expertise. This innovative device incorporates a water jet suction element, which we found to be highly effective in skimming the floating pumice from the water's surface. We remain committed to continuously improving and refining our technology to better address environmental hazards and protect our planet's natural resources.
