Indonesia Tests Dry Ice Technology to Disperse Toxic Haze

The Government of Indonesia has launched experimental atmospheric modification trials using dry ice to disperse toxic haze caused by the country's worst wildfire season in a decade. Following orders from President Prabowo Subianto, the National Disaster Management Agency (BNPB) deployed aircraft to release solid carbon dioxide granules over Palembang and surrounding areas in South Sumatra on October 15 and 16, 2026.

Unlike traditional cloud seeding that induces rain, this method uses 3-millimeter dry ice granules at -75°C to break down smoke trapped in the lower atmosphere, allowing it to rise. During a flight over Sultan Mahmud Badaruddin II International Airport, a Cessna Caravan released 1,600 kilograms of dry ice at 4,500 feet, which immediately improved ground visibility from 650 meters to 2,800 meters. Authorities aim to increase overall visibility from 1km to 5km.

The crisis, exacerbated by a strong El Niño, has caused over 280,000 respiratory cases and sent pollutants into Malaysia, Singapore, East Timor, and the Philippines. In response, the Indonesian National Police have named nine companies and more than 200 individuals as suspects for illegal land clearing. Trials are scheduled to continue until October 18, 2026, with potential expansion to other haze-stricken regions like Central Kalimantan if the tests prove successful.
