STARKLAB - Recycling of industrial fumes thanks to new air-water heat exchanger

TERRAOSAVE aims to remove the gaseous pollution caused by industrial fumes. Its internationally patented system captures the emissions of factories, incinerators, and boiler houses to recycle their thermal energy and treat their pollutants.

A novel stainless steel heat exchanger solution extracts emissions by a bypass installed on the chimney. In TERRAO, different from traditional heat exchangers, the fumes mix directly with water in circulation. This process allows not only for energy reuse through thermal transfer but also for the retainment and subsequent treatment of pollutants, including dust, fine particles, CO2, NOX, metals, and acids in gaseous or solid form.
