In 2012, the World Bank estimated that each person living on planet Earth produces approximately 1.2 kg of waste per day, amounting to 1.2 billion tons per year. By 2025, this number is expected to reach a staggering 2.2 billion tons, which raises the fundamental question: What is and what happens to waste? Domestic burning of waste is a frequent disposal technique in many parts of the world. Further, even when waste is moved to dumpsites in many developing countries, it is not uncommon for the material to be burned by open, uncontrolled fires. In short, fire is the primary mode of waste disposal. Fire provides volume reduction and prevents disease, but inefficient combustion brings its hazards in the form of toxic/noxious gasses. This paper will discuss the work we have been doing at WPI related to burning hazardous waste cleanly and efficiently by observing a tea light candle's behavior. |
