Biomass pellets refers to a selection of unlike pellets formed from a collection of dissimilar biomass raw materials. As the need to replace existing fossil fuel energy sources increases. There will be a greater assortment of wood pellets used to produce energy. Biomass simply refers to any natural material which can be used to generate fuel. In terms of climate change along with global warming, the significant fact about biomass is that it is carbon neutral. What this means is that biomass burning does not place any additional carbon dioxide into the atmosphere, as new wood growth absorbs the carbon released. Biomass pellets are at present the most common in addition to most widespread form of biomass pellets. Biomass pellets are currently produced predominately from timber processing residues. These residues are used to produce premium grade wood pellets. Premium grade wood pellets produce the least ash of all wood pellets. Premium grade pellets due to their high heat value in addition to low maintenance are the most expensive type of biomass pellets.

Other wood residues can also be processed into wood pellets. On the other hand bark for case in point will enlarge the ash content, so the pellets may not be suitable for some pellet burners. Also there is only a limited supply of wood resources to produce wood pellets. This is where other biomass resources must be considered for energy pellets. Grass pellets are still a very new area of wood pellet production. Using grass as a fuel source has many advantages. Grass produces much higher yields than woody biomass, in addition to can be grown in more locations, along with from season to season. Also during pellet production less fuel is required to form grass into a pellet, also by higher productivities. There are however issues along with challenges in combustion grass pellets as there are with straw pellets.

Straw pellets can be formed from waste agricultural residues. This includes for case wheat along with barley straw, in addition to even other wastes such as corn cobs. Burning straw and grass pellets does create challenges in terms of a higher ash content, as well as possible clinker along with slag formations. Straw pellets are currently most commonly used to generate electricity in coal fired power stations, biomass pellets are also used
