Development of an Incinerator with a Multi-Stage Condenser System as an Effort to Reduce CO₂ Emissions Gas from Plastic Waste Burning in Gorontalo City

Abstract

The increasing plastic waste volume in Gorontalo City is not balanced by a good management system, making people choose to burn their waste in open space. Not only makes a bad scene, this burning emits dangerous gases such as CO₂ that contributes to poor air quality and climate change. This study has developed an environmentally friendly incinerator with a stacked condenser system that emits less CO₂ gas. This incinerator consists of three main components: a combustion zone, as the place where plastic waste is burned; a chimney, for the flowing of gas; and stacked condensors, for cooling and keeping the gas before emitting it out. We test the incinerator with and without condensors based on the CO₂ emission from 20 minutes' burning of 1.5 kg of plastic waste. The results show that an incinerator with a stacked condensor system can significantly reduce CO₂ gas emissions by 18.88% more than an incinerator without condensors. This implies that incinerator with stacked condensors can be an alternative way to reduce CO₂ gas from open-space waste burning on a small scale.
