Pellet Power distributes premium wood pellets for domestic and commercial consumption. The thermal conversion of woody biomass in supply and end use consumption can have a considerable impact on the national energy balance in South Africa. Woody biomass, especially in the form of wood pellets (commercial or domestic) is a sustainable source of energy with many potential socio-economic and environmental benefits. When biomass from wood waste or sustainably managed forests, are combusted to create energy the process actually generates no increased greenhouse gas emissions, a circumstance described as carbon neutrality. Solid wood biomass, especially wood pellets, could be a significant contributor in savings on electricity and financial costs, while reducing harmful carbon emissions.
Pellet Power Pellets are now located across South Africa and Namibia (see the store locator to find your nearest Reseller).
Traditional Wood Pellets
Wood pellets, already well known in Europe's energy sector, are gaining popularity elsewhere in the world - especially where significant energy is used for heat -as people realize both the environmental and socio-economic importance of sustainability. Wood pellets offer a completely sustainable alternative to other fuel sources. They burn clean, and, because of health and air quality control considerations, wood pellets are preferable to coal for electricity generation. Produced without additives and part of the natural carbon cycle, wood pellets are net neutral-generating no increased greenhouse gas emissions-if the pellet source material comes from sustainably managed plantations or plantation residuals.
Millions of homes around the world currently use wood pellet stoves for heating. Convenient and begun incorporating wood pellets in their production process because of government mandates for pollution widely available, residential wood pellets are supplied on a small scale and commonly in bagged form. Increasingly, factories, housing complexes, and office buildings, especially in Europe, are using wood pellets to provide heat energy on a larger scale. Electric utility coal plants in Europe have and greenhouse gas emissions regulation. This forward-looking use of combined fuel sources for electricity generation is the future of clean, ecologically sound energy creation in the world.
Pellets burn efficiently
Pellets are compressed wood. The idea that wood makes a great fuel source is ancient, but pellet manufacturers are transforming the process to make wood burn more cleanly and efficiently. Much of the pellet material comes from waste sawdust, shavings, and chips remaining after lumber production; this waste is then compacted into tiny, dense pellets, which burn more efficiently than other forms of wood. Pellets are manufactured with 100% biological materials pressed through small holes in a spherical machine that binds the pellets together. Pellets have far higher combustion efficiency because the binding process reduces moisture to less than 10%, compared to that of an average log, which is typically 50% moisture by weight. Pellets' uniform size, shape, and weight-usually 1.2 to 3 cm in length by 6 mm in diameter - makes them relatively easy to transport and store, as compared to wood logs. Pellet uniformity also allows a machine to measure fuel quantity accurately, in order to feed in a more precise amount of fuel to generate heat or electricity output.
Three grades of pellets are commonly available, distinguished by the amount of ash they produce when burned:
Premium-ash content is less than 1%
Standard-ash content is between 1 and 2%
Industrial-ash content 3% or greater
Because ash is a non-combustible mineral residue, it can be disposed of as inert solid waste. However, many people who burn wood pellets use the ash as fertilizer or compost.
Pellets are sustainable plantations.
While any wood could be used to manufacture pellets, it is important to source biomass responsibly. Fortunately, sustainable biomass feedstock is plentiful in South Africa. In commercial plantations, we find biomass feedstock in two primary forms: understory and forestry residuals. The understory is a forest layer of small trees and plants that, if allowed to accumulate, can prove ruinous during plantation fires by connecting the ground to the canopy, magnifying the effects of what could have been a harmless ground fire. Plantation residual debris encompasses all of the stumps, branches, and tops, loggers leave behind and is often referred to as slash. When the understory and plantation residuals are left to decay in nature, they often harbour diseases that, if left to spread unimpeded, have the potential to infect whole forests. What's more, their eventual decay in nature emits more methane than their incineration in pellet burners.
Plantations could benefit from regular tree management; ridding them of understory and residual waste. Many trees can be responsibly and sustainably harvested to maintain efficiency. Planting, harvesting, and replanting biomass indirectly dedicated to energy production are key elements of an integrated biomass energy system.
