The use of soft sawmill waste for the production of fuel briquettes

A large amount of wood processing waste has accumulated in the timber industry in Russia in recent years. Their processing into solid biofuel may be one of the ways of their utilization. Briquettes and pellets are the most technologically advanced kinds of solid biofuel produced from wood waste. This is an environmentally friendly fuel, the use of which increases environmental safety. In the analytical review the stages of the technological process of fuel briquettes production from sawdust are considered in detail. The characteristic of different types of briquettes is presented. The use of environmentally friendly binders based on plant polymers in the production of solid biofuel can improve their strength, water resistance and calorific value. The analysis showed high growth rates of biomass use for heat production, both in the private sector and in the district heating systems. Production of briquettes and pellets is actively developing in Europe, in the US, Canada. Russia has the world's largest reserves of raw materials suitable for energy purposes. Significant amounts of solid fuel are produced and exported by Russian enterprises to foreign countries. The amount of domestic consumption of solid biofuel in our country increases significantly every year. Processing of wood waste into fuel briquettes and pellets is an environmentally friendly technology.
