The collection and disposal of municipal waste are one of the most essential measures that are needed to protect the environment and public health of each city and country. There are common ways to dispose of municipal waste including waste landfill, incineration, and Recycle, but for many wastes, incineration is one of the best or most necessary methods for waste management. Burning waste and converting it to ash is a healthy way to eliminate waste, with many benefits. However, there are concerns about the emission of pollutants such as carbon dioxide, sulfur and nitrogen compounds, etc., which are the result of burning waste. To solve this problem, a device was designed to dispose of and burn waste. The air, and smoke from the waste combustion guided by a powerful blower fan, to the HEPA filter embedded in the device. The HEPA filter was coated with porous nanocarbon material to absorb more contaminants. The body was made of metal and its dimensions were 50*50*50 cm. An adapter was used to power the fan. The CO2 gas sensor, an Arduino board, and an LCD were used to monitor the performance of the device. It has a replaceable filter and can be easily removed and replaced. At the end of the apparatus, a chamber was installed for the ash to separate the ash easily. The resulting ash was then used to Strength the concrete. It also reduces the volume of waste, reduces disposes of hazardous waste, reduces odor, reduces the need for landfill, and reduces pollutants such as carbon dioxide and greenhouse gas emissions.
