Sanitary Napkin Incinerator (Version 4)
A novel incineration device has been developed that uses pyrolysis to decompose sanitary napkins into hydrocarbon vapours and combustible gases along with some non-combustible gases and char. These vapours and gases are made to pass over high temperature electric coils (>500 degC) where they auto-ignite in the presence of oxygen. The heat from the flames partially drives the pyrolysis of remaining sanitary pads. A smoke stack thermocouple sensor feeds back values to a PID controller implemented through a microcontroller to maintain proper pyrolysis and combustion conditions that result in a transparent flue gas exiting from the chimney.
- It completely incinerates 5–20 used sanitary napkins in less than 30 min.
- A provisional patent has been filed.
- Unit is successfully lab tested for 500+ pads as lab trial. It is installed in ladies hostel for field testing.
- Technology is transferred to M/S Climber Enviro Solutions
LLP for commercialization of this technology.
