Biomass is material originating from plant and animal matter. Biomass energy uses biomass to create energy by burning organic materials. The heat energy released through burning these materials can heat homes or water. Heated water produces steam, which in turn can generate electricity. Using organic materials to create heat and power is an eco-friendlier alternative compared to using fossil fuels. Here’s more about the benefits of biomass energy
1. Indefinitely Renewable
The majority of the world’s energy comes from burning fossil fuels. Fossil fuels are a finite resource. Once fossil fuel resources run out, new fuel sources will be needed to meet global energy demands. Biomass offers a solution to meet this need.
Organic waste material from agriculture and logging operations, animal manure, and sludge from wastewater treatment are all viable fuels for generating biomass energy. As long as the earth is inhabited, these materials will be readily available.
2. Reduce, Reuse, Recycle
Organic waste that would typically be disposed of in landfills could be redirected for biomass energy use. This reduces the amount of material in landfills and slows the rate at which landfills are filled. Some of the most common waste products used for biomass energy are wood chips and agricultural waste products. Wood materials can easily be converted from already existing wood structures that will be destroyed, such as wooden furniture and log cabins, preferably both would also come from responsible logging and practices as well.
As more organic waste is diverted from landfills, the number of new landfills needed would be reduced. Older landfills are at risk for leaking leachate. Leachate contains many environmental pollutants that can contaminate groundwater sources.
Burning fossil fuel releases carbon into the atmosphere which was previously trapped below ground. Trapped carbon isn’t at risk for contributing to global climate change since it can’t interact with air. Each time fossil fuels are burned, they allow previously trapped carbon to enter the atmosphere and contribute to global climate change. In comparison, biofuel is carbon-neutral.
The materials used to create biomass energy naturally release carbon into the environment as they decompose. Living plants and trees use carbon dioxide to grow and release oxygen into the atmosphere. Carbon dioxide released by burning organic material will be absorbed by existing plants and trees. The biomass cycle is carbon-neutral as no new carbon is introduced to the system.
3. Smaller Carbon Footprint
The amount of unused farmland is increasing as agriculture becomes more efficient. Maintaining open land is expensive. As a result, farmers are selling off their property for new developments. Unused open agricultural land could be used to grow organic material for biofuels.
Converting open tracts of land to developed areas increases the amount of storm-water runoff. Storm-water runoff from developed areas contains more pollutants than storm-water runoff from undeveloped areas. Using open areas to grow biomass sources instead of creating new developments would reduce water pollution.
Forested areas also provide sources of biofuel material. Open land converted to sustainable forestry would create new animal habitats and offset carbon emissions from existing fossil fuel sources as more plants and trees would be available to absorb carbon dioxide.
4. Social Benefits of Biomass Energy
Burning fossil fuels releases sulfur dioxide, mercury and particulate matter into the atmosphere which can cause asthma, cancer and respiratory problems. Biomass energy emits less harmful byproducts compared to fossil fuels, which means cleaner air and healthier people.
Biofuel can improve rural economies by providing more people with unused land the opportunity to grown biomass material for energy use. Workers would be needed to harvest and process the materials needed to generate biofuel.
Since biomass is a renewable energy source, energy providers can receive tax credits and incentives. Countries with land resources will be less reliant on foreign fossil fuel providers and can improve their local economies.
Increasing biomass energy usage can reduce forest fires. Selectively reducing brush can still reduce the risk of wildfires spreading. Exposing underbrush and groundcover to rainfall decreases the change of it drying out and creating optimal, fire spreading conditions.
Biomass Energy in Denmark
Denmark is an example of how effective biomass energy can be in improving energy efficiency. Approximately 70 percent of renewable-energy consumption in Denmark comes from biomass.
Woody biomass creates an increasing percentage of heating from combined heat and power (CHP) plants with a goal to for 100 percent of hearing to be derived from woody biomass by 2035. Another form of biomass is agricultural biomass. This form utilizes materials such as straw and corn to create end-products like electricity, heating and biofuels.
The Danish Energy Agency has developed a plan including four scenarios that will help Denmark become fossil fuel free by 2050. The biomass scenario involves CHP for electricity and district heating, indicating that biomass energy is important in Denmark’s energy sector today and will play an increasingly important role in the future.
Biomass offers an eco-friendly and renewable method of reducing pollution and the effects of global climate change. And, like other forms of renewable energy, the products needed to develop biomass energy are readily available.
