Committed to Eliminating the Physical and Environmental Footprint of Municipal Solid Waste


Landaira is dedicated to global environmental improvements that foster a sustainable future and the elimination of the solid waste footprint for a greener tomorrow.


With our Thermal Conversion technology developed in 2009 in Tennessee, Landaira is dedicated to global environmental improvements that foster a sustainable future and the elimination of the municipal solid waste footprint for a greener tomorrow.

Landaira’s patented thermal conversion technology transforms solid waste into carbon, ash, and a clean-burning synthetic gas, which can be used to produce heat or electricity. Landaira’s process is simple, requiring no additional outside processing, and capable of being scaled over time to meet growing municipal needs.

Landaira’s process can accommodate a wide range of carbon-based waste streams and in terms of output produces several value-added products, such as bottom ash for concrete aggregate, sterilized recyclables, and synthetic gas for power production. At no point during the Landaira process does combustion of waste occur, both temperature and air content within the autoclave are highly regulated to prevent the formation of toxic emissions.
