Recently, research on biofuel production processes from biomass raw materials has become very popular in many scientific centres. As a results of the conducted research, the parameters of a wide range of raw materials and the influence of biomass parameters and process conditions on the final product properties are known, and new technologies are being developed. However, many questions and uncertainties remain. This is due to the diversity of raw material origin, the variety of final products (solid, liquid, and gaseous biofuels), and the multitude of technologies used. Once a greater understanding is obtained in these areas, it will be possible to fully utilize the biomass potential and effectively conduct production processes to obtain high-quality biofuels with minimal effort.
This Special Issue will focus on: biomass pretreatment as well as biofuels process production and optimization with respect to process costs while maintaining high product quality. We therefore invite papers on biomass pretreatment technology, innovative biofuels production technology, modelling and optimization studies, reviews, and case studies. Topics of interest for publication include, but are not limited to, the following:
- Technical, economic, and environmental aspects of solid, liquid, and gaseous biofuels production;
- Optimization of biofuels production processes;
- Impact of raw material processing on product parameters;
- Ensuring high-quality biofuels;
- Technology assessment;
- Processes modelling, forecasting, and optimization techniques.

Abstract: Drying of spruce, beech, willow, and alder sawdust was investigated in a laboratory type dryer. The effect of drying air temperature (25, 60, and 80 °C) and airflow velocity (0.01, 0.15, and 1.5 m/s) was investigated. The results have shown, that drying air temperature and airflow velocity influence on the drying behaviour of sawdust. The experimental dehydration data of sawdust obtained were fitted to the theoretical, semi–theoretical, and empirical thin-layer models. The accuracies of the models were estimated using the correlation coefficient (R), root mean square error (RMSE), and reduced chi–square (χ2). All models except theoretical model of a sphere described the drying characteristics of sawdust satisfactorily. The effect of drying air temperature and airflow velocity on the drying models parameters were also determined.

Abstract: Determination of mass diffusion coefficient for dried, inhomogeneous material is difficult as it depends on drying agent temperature, moisture content and physical structure of the material. The paper presents the method for efficient determination of water diffusion coefficient for solid cuboids, dried using convective drying method. The material for drying included shoots of common osier, robinia (false acacia), multiflora rose, energy poplar, dried in the temperatures of 40, 50, 60, 70 and 80 °C, in the free convection. The obtained results differ from the theoretically anticipated changes of the coefficient.

Abstract: Georgian forests are exceptionally valuable natural resources, both on a regional and global scale. However, the high level of poverty in rural areas and the lack of affordable alternatives to firewood force people to use forest resources illegally and unsustainably. In this context, short rotation plantations with poplars seems to be a good alternative to obtain additional biomass for fuelwood for the country. Therefore, the objective of the study was to determine the productivity and energy value of five poplar clones as a potential source of commercial fuelwood for the country. The genetic material consisted of five clones. Three clones 89.M.061, 89.M.004 and Kocabey (TR - 77/10) were obtained from Turkey; the fourth clone - AF8 was produced by Alasia Franco Vivai in Italy, while Populus pyramidalis was used as a control. The productivity and wood properties of the clones were tested after three years of growth. The survival rate of the clones was generally high. No significant differences in biomass production (dry matter, DM) were found between the four tested clones (DM approximately 4 Mg ha-1 yr-1), while the control clone reached significantly lower DM values than all other clones. In conclusion, the four clones should be further considered for commercial biomass production and tested at different test sites in Georgia to evaluate the interaction between genotype and environment and to identify suitable site conditions required to justify an investment in intensive culture.
