“…Due to the growing demand for green energy, biomass fuels such as wood pellets are being increasingly used, especially in low-power systems. However, the growing demand for biofuel necessitates a search for alternative raw materials, e.g., energy crops [1] and agri-food waste (waste biomass) [2][3][4]. The use of the latter raw material in particular is an optimal approach to solve issues related to waste management in accordance with the principles of sustainable development [5].…”

Energy Parameters of Miscanthus Biomass Pellets Supplemented with Copra Meal in Terms of Energy Consumption during the Pressure Agglomeration Process

The process of pelleting miscanthus biomass often encounters issues related to the low durability of the obtained pellets and high energy inputs. To solve these issues, the use of copra meal as a supplement is proposed. This paper presents the results of research on energy parameters of miscanthus biomass pellets supplemented with copra meal in terms of energy consumption in the pressure agglomeration process. As part of this research, the energy parameters of miscanthus biomass, copra meal biomass, and their blends were characterized. Next, the raw materials were used for the production of pellets in the pressure agglomeration process. The investigations included proximate and ultimate analysis and estimation of heating values. Moreover, the total fat content, mechanical durability, kinetic strength, and bulk density were determined, and the energy consumption in the pelleting process was assessed. The results indicate that the energy consumption in the miscanthus biomass pelleting process can be substantially reduced by adding copra meal as a biocomponent. When the copra meal addition did not exceed 30%, the pellets exhibited over 95% durability, over 1200 kg∙m−3 density, and over 417 kg∙m−3 bulk density. Given the 44% reduction in energy consumption in the pellet production process and the energy efficiency of 4815 Wh·kg−1 determined in this study, copra meal may be an interesting material for use as an additive in the production of miscanthus biomass pellets.

“…Studies on RCG for energy purposes started in 1981 (Venendaal et al 1997), and a steady increase in cultivation started shortly after due to the adjustment of the Swedish agricultural policy in 1991 (Larsson 2006). RCG has been used in pellet production (Jasinskas et al 2020) and biogas generation (Roj-Rojewski et al 2019). It has been studied that the costs of RCG cultivation are lower than willow, which has already shown promising potential for commercial production in energy use (Venendaal et al 1997).…”

Lignocellulosic energy crops can produce substantial amounts of biomass for energy purposes, but their introduction implies land-use changes as they are mainly cultivated in agriculturally dominated landscapes. This thesis presents a land-use analysis of lignocellulosic energy crops in the agricultural landscape in Sweden, specifically aiming to i) assess different energy crops’ regarding production, location and climatic profiles, ii) characterise and define the surrounding agricultural landscape, and iii) study the overall land-use changes derived from the establishment of energy crops in the country. The analysis is based on empirical data from commercial fast-growing tree plantations (willow, poplar, and hybrid aspen) and energy grasses (reed canary grass) at multiple spatial scales from field to landscape level, during the period 1986-2018. At field level, there is a trend for smaller and more regular fields dedicated to energy crops, with cultivation patterns moving towards more productive lands, reflecting an intensification in the land-use management. Willow was initially established mainly on fallow lands, but many plantations were subsequently replaced by cereals due to changes in global cereal prices. In the case of grasses, this pattern was similar, although changes appeared later and not so markedly. At landscape level, energy crops significantly diversify the agricultural landscape, as fast-growing tree plantations are largely introduced in cereal areas and grasses in forest-dominated landscapes. The methods and analysis of this thesis contribute to a better understanding of land-use changes associated to energy crops, and help define their contribution to diversifying the agricultural landscape.

The study discussed the use of phosphogypsum by-product waste in anaerobic digestion processes. Besides the production of biogas from plant substrate with the addition of phosphogypsum, the focus was placed on the enrichment of digestate with phosphogypsum as a mineral additive to increase the concentration of valuable macro-and microelements. The component composition of the obtained digestates was analyzed, and opportunities for additional research were determined. Research on the use of mineral additives in anaerobic digestion is considered promising. Phosphogypsum favors the quality of digestate as an organic mineral fertilizer with a higher content of mineral components. Furthermore, the contribution of phosphogypsum to plant substrate to achieve higher biogas production is not apparent, but with an impact on the component composition of biogas; however, there is an opportunity to consider the potential benefits of using the additive with another type of substrate waste for the anaerobic digestion process.
