Rotary kilns: important link in the circular economy Indaver tries to recover as many materials as possible from waste for the purpose of recycling and reuse. However, certain waste flows, including critical and sensitive waste from the chemical and pharmaceutical industries, require thermal treatment to prevent hazardous substances from finding their way into the material or food chain.

Convective heat transfer in a rotary kiln was studied as a function of operating parameters. The experiments were carried out in a steel kiln of 0.19 m in diameter and 2.44 m in length. The operating parameters covered included gas flow rate, solid throughput, rotational speed, degree of solid holdup, inclination angle, particle size and temperature. To minimize radiation effects, air was used
