Food waste is a major global problem. Around 30% of all food produced is wasted, and when it goes to landfills, it decomposes without oxygen and produces methane — a greenhouse gas much stronger than carbon dioxide.
Although composting is a solution, traditional composting often fails because:
Temperature is not monitored
Carbon and nitrogen balance is incorrect
Poor aeration causes odor
Users do not know if it is working
Our solution is a 3D Printed Smart Composting System that makes composting controlled and data-driven.
The system includes:
A double-wall insulated 3D printed compost container
An Arduino temperature sensor
A mobile app dashboard for real-time monitoring
By maintaining the optimal temperature range of 45–65°C, the system ensures efficient microbial activity, faster decomposition, reduced odor, and better compost quality.
We will prototype, test, and compare it with traditional compost bins, measuring temperature stability, compost maturity time, and performance.
This solution can be used in homes, schools, and communities.
It reduces methane emissions, supports sustainable living, and integrates biology, engineering, and technology into one practical system.

The 3D Printed Smart Composting System is a compact, insulated compost bin equipped with a temperature sensor and mobile app monitoring. It helps users maintain the optimal conditions for microbial decomposition, reducing methane emissions and speeding up composting. By combining biology, engineering, and real-time data tracking, the system turns traditional composting into a smart, efficient, and sustainable solution for homes, schools, and communities.
