The wood arrives to the yard Wood arrives at the plant via truck and is sent to one of four places: the wood storage yard, the wood circle (where wood is primed for processing), the piles of sawdust and woodchip, or straight …
Similarly, the combined biomass (bio) also exhibited a reduction in CO2 and SO2 emissions, especially on a dry basis. On a dry basis, all co-fired pellets exhibited lower CO2 and SO2 emissions than the coal pellets. Hence, co-firing of biomass and coal pellets is a valid method of mitigating GHG emissions and for cleaner energy utilization.

the pellet, and it produce the pellets less durable [14, 15]. In biomass densification, lignin plays a major role. The influence of lignin on the bonding characteristics of densified pellets can be attributed to its low melting point (140°C). Due to heating, lignin goes to soften at first and then melts to exhibit thermosetting properties
