Why is biomass ecological?
When we speak of biomass we mean any type of organic substance derived directly or indirectly from the photosynthetic activity of plants. It represents the most sophisticated form of solar energy storage which is transformed from light energy into chemical energy and stored in organic molecules through chlorophyll photosynthesis. For this reason it is a renewable and environmentally friendly energy resource as the carbon dioxide produced during combustion is reabsorbed by plants through photosynthesis.
Its origin is correlated with the more general carbon cycle. This element enters the cycle in the form of carbon dioxide (CO2) and is fixed in more complex compounds of organic nature thanks to plants and their photosynthetic activity. They use solar energy to process water and mineral salts substances such as lignin, cellulose, hemicelluloses, starches, sugars, etc., which constitute the vegetable biomass. A part of this material passes into the food chains of animals to be re-processed in the form of fats, lipids, proteins, etc., through herbivores and constitute
instead of animal biomass.
The carbon cycle closes when all of the organic Carbon with photosynthesis returns to the atmosphere in the form of CO2 through a decomposition process.
