A large amount of waste heat is released from burning waste materials like plastic, which is typically lost to the environment. There's a need for a system that can harvest this waste heat to generate electricity safely and efficiently.

This project presents an eco-friendly electricity generation system using the TEC1-12706 thermoelectric module, which converts waste heat from burning plastic or dry waste into electrical energy. The TEC1-12706 module is placed on a metal surface heated by combustion, while the other side is kept cool using a heat sink and cooling fan, creating a temperature difference. Due to the Seebeck effect, the module generates DC electricity, which can be used to power LEDs, charge a battery, or run a small device. The system also integrates temperature sensors (like DS18B20 or LM35) and a microcontroller (Arduino/ESP32) to monitor hot and cold side temperatures in real-time, ensuring the module operates safely and efficiently. This project helps recycle energy from plastic burning, reduce dependency on the grid, and demonstrates a practical way of turning waste into a renewable power source.
Burning plastic or dry waste generates heat in a metal chamber. A TEC1-12706 thermoelectric module is mounted between the hot metal base and a cooling plate with fan to create a temperature gradient. The module converts the heat difference into DC electricity (approx. 2–5V and 0.5–1A depending on conditions). The generated voltage is passed through a voltage booster (MT3608) to make it usable for charging batteries or powering devices. Temperature sensors monitor both sides of the TEC1 module, and a microcontroller displays the values on an LCD or OLED display, while also managing fans and alerting if overheating occurs.
