Today the major problem of environment is pollution. The World is suffering with the increase of pollution day by day. Pollution affects the air, water, land & soil etc. We burn fossil and other fuels like Wood, Paper, coal, Heavy waxes, etc to produce useful Energy and Heat for Industrial and Domestic uses, which is a major cause in the rapid- increase of pollution. In this article; review of forming non- polluting, high thermal and burning efficiency briquettes with pine needles by rapid prototyping process either liquid based or powder based were studied along with the use of various binder materials. The main objective of this study is to make or form a non- polluting, high thermal value, high density, high burning efficiency, less smoke, less ash content briquettes and also make a comparison with coal and different binder material briquettes by proximate and ultimate analysis. It has been found that pine needles briquettes formed with paper starch binder material have high burning efficiency, high calorific value, less smoke, less ash content as compared to pine needle briquettes formed with binder materials clay and cow dung . In the formation of the non-polluting pine needle briquettes, the proper selection of binder material along with proper quantity along with pine char is essential for better results. With the use of pine needle briquettes formed with binder materials like paper starch, clay, cow dung, etc. may become better alternative of coal and other fuels required for domestic and industrial purposes and also to overcome the pollution problem of the world.
