“…Waste that is generated in the production of sunflower seeds and is used for energy purposes produces large amounts of volatile substances at a level from 70.4% to 77.1% [49]. Studies on pellets made from agricultural waste have shown that they have volatile matter from 64.54% [50] to as high as 87.75% [51]. Wood pellet made of Norway spruce wood was characterized by an amount of volatile compounds at a level of slightly higher than 82%.…”

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.

Buckwheat husks are a valuable source of carbon and show the potential to be used as an energy source. However, due to low bulk density and low susceptibility to compaction, it is beneficial to use them in the form of co-pellets. The study presents comprehensive research detailing buckwheat husks’ potential for co-pelletization with oily (peanut husks) and dusty (senna leaves) agri-food wastes, whereas the effect of material parameters such as the amount of additive (10, 15, 20%) and the process parameters as the die rotational speed (170, 220, 270 rpm) on pellets’ quality (kinetic durability, bulk and particle density, degree of compaction) and the energy consumption of the pelletization process were examined. Ten percent of potato pulp as a binder was added to each pelletized mixture. It was found that an increase in the senna leaf content affects positively the kinetic durability of pellets. The fatty peanut husks have a negative effect on the pellets’ quality (measured by the kinetic durability and bulk density); however, both additions of senna leaves and peanut husks are lowering the energy consumption of the pelletizer. The highest quality pellets and the addition of 10% peanut husks to buckwheat husks (kinetic durability of 96%) and 20% of senna leaves to buckwheat husks (kinetic durability of 92%) obtained at 170 rpm were subjected to combustion in a fixed-bed unit, and the content of CO, CO2, NO, SO2, HCl, and O2 in the fuel gases was measured. The emission factors were higher than the Ecodesign limitations (CO > 500 mg·Nm−3, NO > 200 mg·Nm−3). The obtained results indicate that buckwheat husks can be successfully co-pelletized with other waste biomass; however, the pellets to be combusted require a boiler with improved air-supplying construction.

“…This reduction can be described by compaction degree ID defined as relation of granules density to the bulk density of raw material [26]. In the case of different biomass ID is about: 4.01 for onion husk [27], 2.15 for tobacco waste [28] or 2.1 for reed canary grass [29] and 2.6-4.1 for different wood species [30]. Probably the similar or higher values can be expected for leaf biomass.…”

The paper presents the results of research aimed at evaluating the possibility of using selected tree leaf species to produce solid biofuels. The possibility of production of qualitative solid biofuels from urban tree leaves meets the expectations of the municipal sector. Collection of tree leaves in urban areas is very often necessary for road safety reasons, the need to collect biomass rich in dust and pollution as well as biomass infested with pests. The production of solid biofuels from tree leaves allows for effective management of this raw material with energy recovery. The performed research indicates such a possibility, and the obtained ash is used as a soil improver. The conducted research showed that the biomass of leaves of five tree species used in the experiment can be a source of raw materials for production of qualitative biofuels. The obtained pellets were characterized by properties comparable to those of classical wood pellets. The lower heating value of the obtained pellets ranged from 14.5 to 15.5 MJ∙kg−1. Physical properties of the obtained pellets described by bulk density (BD 600–660 kg∙m−3), mechanical durability (DU 90–96%), moisture (Mar 10–12.5%) indicate that these products can be used in existing combustion equipment. Preliminary analysis of the obtained ashes (determination of ash melting point, bulk density) indicates that they should not cause difficulties in ash removal systems from the combustion chamber.
