With the whole world facing the consequences of altered climate because of indiscriminate use of available natural resources, people are turning to more environment-friendly alternatives. Of considerable importance in this regard is the advent of boilers that do not require fossil fuels. These boilers work by consuming organic materials instead of non-renewable fuels. Switching over to these boilers might seem like an easy task, but one has to consider a lot of factors while making a shift from conventional boilers that use fossil fuels to biomass boilers that require sustainable organic material.
While the most obvious advantage of switching over to sustainable energy sources is the betterment of the environment, the practicality of these boilers is offset by the high costs of processed wood pellets that are the most common fuel for these boilers. In the following section, the various alternatives that can be used as biomass fuel instead of wood pellets are discussed.
Waste from forest
The first option of biofuel is waste generated from forestry activities. Typically, the amount of waste generated in the forest because of fire prevention and forest management methods is huge. This waste is disposed of by burning. Such uncontrolled combustion releases a lot of pollutants in the air that ultimately affects the human health adversely. This waste could be put to a much better use by being used as a biofuel.
Waste from animals
Animal waste is a rich source of energy that can be tapped in biomass boilers. There is a lot of animal waste that gets accumulated in the form of manure, livestock waste and food processing waste. The most typical application of this kind of waste is in enriching the soil for agriculture. However, with the rise of biomass technology, it is possible to convert this waste into a more energy efficient form of biofuel.
Another great option for obtaining a biofuel is to find more application of crops that provide biofuel and perform a planned cultivation over large areas. This way, we will not only obtain a useful crop but also the good yield of biofuel. For example, some types of corn yield ethanol synthesis and soybean cultivation for a kind of biodiesel.
Residential wooden waste
There is tremendous scope for converting residential wooden waste into a usable biofuel. Typically, most of the residential waste ends up in the landfill. An environmental load of this landfill could be decreased to a great extent if a proper conversion of this waste is done to make biofuel.
The above-mentioned alternatives to traditional wooden pellets that are used as fuel for biomass boilers would be more environment-friendly. These would also bring down the cost of biofuels drastically. Many strategies for generating biofuel from these resources are still in infancy and might require some solid research before they are put to use on a large scale. However, keeping these options in mind is necessary for finding innovative solutions to the problems posed by burning fossil fuels and other non-renewable sources of energy.
