Global warming is one of the major issues of the present era. One of the best conducts to reduce such global environmental issue is sustainable use of available natural resources. This study emphasis on the usage of pine needles and agricultural waste to produce energy due to its less polluting nature. Also in the lower Himalayan regions, these are collected and removed from residential and nearby forest areas. The use of such waste pine needles also helps in controlling forest fires during summer season and maintaining ecological balance. In this study we have made an attempt to highlight the comparative study of briquettes produced from mixture of pine needle with rice husk and wheat residue.
