The Pyroclave is a medical wasteprocessor that uses pyrolysis —the process of decomposing organic material using extreme heat in the absence of oxygen. It is this same process that is used in the creation of charcoal and in the conversion of coal to coke.

Unlike incineration or burning, which requires oxygen and creates harmful by-products like dioxin, furans and carbon dioxide; pyrolysis produces fewer by-products. The process effectively carbonizes all solid material and produces 50% less carbon dioxide, it is claimed.

Pyrolysis has been touted as a viable option for medical waste management, but the cost has so far been prohibitive.
