This article discussed how food waste can be used to generate energy through a process called Biomass Gasification. This method utilizes heat, oxygen, steam, or a combination of these to transform biomass, which includes food waste, agricultural waste, and other biological materials, into a variety of gases suitable for fuel. This process operates by putting semi-dry food waste into a device that resembles a cooking pot and passing it through a heated, boiling material that turns it into fuel gas, known as fluidization. Fluidization converts food waste into high-valuable energy sources known as syngas, which can be used for heat and power. Biomass gasification is efficient, sustainable, and carbon-neutral, offering an eco-friendly alternative to fossil fuels. It also reduces landfill waste and the cost of waste management. Countries like Canada, Finland, and Costa Rica are using this technology to produce energy from waste. The process supports a circular economy and offers significant environmental benefits.
