Eco-fuel briquettes for sustainable development

Raw coal is still burnt as fuel in many developing countries. Besides pollution from coal combustion, coal briquettes always face problems during transportation and storage because they are friable and susceptible to moisture. On the other hand, plastic waste in municipal solid waste is also a big problem which many countries are facing. Since synthetic plastics originate from petroleum products, plastic waste has high energy content. To solve these problems, a new solid fuel called Eco-fuel has been developed by briquetting a mixture of coal and different plastics. The commonly used plastics (polyethylene and polystyrene) were used in this study. Eco-fuel is clean, strong and easy to handle. It is easier to ignite than raw coal. Eco-fuel is resistant to water and water vapour. The acidic emissions of Eco-fuel are lower than that of coal briquette and can be well controlled by adding lime products.
