“…In most cases, this biomass, after being collected, is transported to landfills and composted there. It is worth paying attention to the energy potential of this raw material and its use as a source of energy because waste in green areas is generated regularly and throughout the year [2].…”

“…Obtaining energy by incinerating waste from green areas is another method of managing this type of waste. In order to obtain energy, biomass that is fragmented or in the form of briquettes or pellets has been used [2]. Another way to use green waste is the production of biogas.…”

“…Currently, fossil fuels cover about 80% of the world's energy demand [1]. Fossil fuels in the future will not be sufficient to cover the energy demand, therefore the future for the global economy may be renewable energy sources, which include, among others, energy from biomass [2]. Biomass is the oldest and most widely used renewable energy source.…”

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·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·m3), while the lowest emission of nitrogen oxides was recorded for pellets made of a mixture of coniferous sawdust and pinecones (65.33 mg·m3). 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.
