Biomass from Green Areas and Its Use for Energy Purposes

In the current situation, fossil fuels are the primary source for electricity production. As a result of activities related to environmental protection, other sources are also used to produce energy. One of the renewable sources is biomass, which is becoming more and more popular for economic reasons. Biomass produced in green areas is a source of energy that has not been used in an appropriate way so far. This scientific article presents the possibility of using biomass from parks and gardens for the production of pellets and the assessment of their properties in terms of the possibility of using them for energy purposes. Coniferous sawdust was an additional component of the pellets. The produced pellets were tested for mechanical, thermogravimetric, and calorimetric properties. It was found that pellets made of biomass consisting of fir (493.12 N) and pine (450.84 N) cones with an addition of coniferous sawdust were the most resistant to mechanical damage. The amount of ash in the analyzed pellets was below 3%, and their calorific value ranged from 16.95 to 19.54 MJ center dot kg(-1). Additionally, during pellet combustion, the lowest emission of sulfur dioxide was recorded for pellets made of sawdust from coniferous trees and acorns (1.01 mg center dot m(3)), while the lowest emission of nitrogen oxides was recorded for pellets made of a mixture of coniferous sawdust and pinecones (65.33 mg center dot m(3)). The emission of the tested gases decreased as a result of the addition of coniferous sawdust to the tested types of biomass. On the basis of the conducted research, it was noted that waste biomass formed in green areas can be a raw material for energy production.

Automated summary

Currently, fossil fuels are the main source of electricity production, although other sources, including biomass, are being explored due to environmental concerns. This scientific article examines the possibility of using biomass from parks and gardens for pellet production, specifically assessing their mechanical, thermogravimetric, and calorimetric properties. The study finds that biomass pellets made from fir and pine cones, with the addition of coniferous sawdust, show the highest resistance to mechanical damage and have a low ash content. Furthermore, the combustion of these pellets results in lower sulfur dioxide and nitrogen oxide emissions compared to other biomass mixtures. Overall, this research suggests that waste biomass from green areas can be a valuable raw material for energy production.
