Oil and gas prices continue to rise, and will continue to rise in the future. At a time of economic recession the pressure of meeting fuel and energy bills is becoming more and more difficult to manage. Concerns over global warming are also gaining attention, as fossil fuels are seen to be a direct cause of temperature increase. Oil and gas are trapped forms of carbon from under the ground. When we use fossil fuels we then release this carbon into the atmosphere. However this carbon is not part of the current carbon cycle as it has been kept deep underground, it was part of a previous carbon cycle. Plants and trees are part of the current carbon cycle, as the plants grow they absorb carbon dioxide and when they die and decay or are burnt this carbon in then released back into the atmosphere. New tree’s and plants re-absorb this carbon, and therefore carbon dioxide levels should be fairly stable. By burning fossil fuels we are placing additional carbon into the atmosphere, which leads to the greenhouse effect and traps the suns heat, leading to climate change. Therefore alternative and renewable energy sources are being considered. And to use these energy sources efficiently, upgrading them into pellets.

Pellet manufacture is using heat and pressure to reform different materials into pellets. Pellets can be made into various different shapes and sizes, and from a wide range of raw materials. By producing pellets from a raw material, it is possible to increase the density of the raw material, even up to factors of ten or more. A high value fuel has been produced from a low density, low value raw material. Which is cheaper to transport and is easier to design systems for their use, for example pellet stoves and boilers and their hopper and auger feed mechanisms.

Producing pellets is a skilled process, and requires the right equipment, the right knowledge and the right raw material. Without all of these factors working together, efficient pellet production is not possible. For example there are various pellet mills and pellet presses available in various different sizes and productivities. However, a key mistake that is made is to purchase a pellet mill that has productivity beyond the capabilities of the other process equipment. If your setup cannot prepare quality consistent raw material at the correct moisture content, then the capabilities of the pellet mill are wasted. So understanding the true abilities and productivities of the equipment is crucial to produce a balanced setup. A balanced setup is a more efficient way to spend resources and will also be more energy efficient.

Is global warming caused by man or is it just a naturally accruing event? and ‘is our use of fossil fuels the cause’. Within the recent years the augments against the fact that our use of fossil has a direct effect on global warming have subsided. Now, whether fossil fuel combustion is the sole cause is still debated, however it is clear that increased CO2 levels due to fossil fuel combustion is a contributing factor of climate change. The problem is almost every aspect of the modern lifestyle is dependant on oil and gas, whether it’s heating our homes or driving our cars. Put simply we live a fossil fuel way of life, and things have to change. We therefore need to look to alternative methods to generate the energy we need to power our lifestyles and future development. There are several options available to use this include solar, wind, wave and biomass.

All alternative and renewable energy forms must be considered to power our future, and the use of biomass has several benefits. One of the key benefits of biomass is it is a cultivate resource; this means a biomass economy could evolve on the cultivation, processing and distribution of various biomass energy products. These products can include oil products such as ethanol and bio-diesel, bio-ethanol can be produced from any biomass resource no just corn, in fact corn should be solely used for food and the waste corn cobs and straw should be used to produce ethanol. Biomass can also be processed in to solid fuels such as pellets. Biomass pellets can be used in stoves and boilers to heat or to cook on. A biomass economy unlike a fossil fuel economy is decentralized, as almost anyone in any location can cultivate some form of biomass. Therefore monetary resources are spread more evenly through the world economy instead of certain oil states acquiring obscenely large amounts of monetary assets.

Biomass can be processed in a pellet mill or pellet press into a high density, high value solid fuel. Pellets are well suited for stoves and boilers as they flow similar to oil. By compressing biomass into pellets a much higher and more efficient combustion temperature can be achieved. Once a biomass pellet fire is up to temperature no visible smoke can be seen coming from the fire, and for developing countries with health risks from poor combustion wood fires, pellets offer a way to improve their health and quality of life. So there are other options to fossil fuels, we just need to invest in alternative technologies to develop them in the energy sources of the future.
