The effect of foliar application of Cyanobacteria and Chlorella sp. monocultures on physiological activity, element composition, development and biomass weight of basket willow (Salix viminalis L.) and the possibility to prepare biofuel from it in the fortification process was studied. Triple foliar plant spraying with non-sonicated monocultures of Cyanobacteria (Anabaena sp. PCC 7120, Microcystis aeruginosa MKR 0105) and Chlorella sp. exhibited a considerably progressive impact on metabolic activity and development of plants. This biofertilization increased cytomembrane impermeability, the amount of chlorophyll in plants, photosynthesis productivity and transpiration, as well as degree of stomatal opening associated with a decreased concentration of intercellular CO2, in comparison to control (treatments with water, Bio-Algeen S90 or with environmental sample). The applied strains markedly increased the element content (N, P, K) in shoots and the productivity of crucial growth enzymes: alkaline or acid phosphorylase, total dehydrogenases, RNase and nitrate reductase. Treatments did not affect energy properties of the burnt plants. These physiological events were associated with the improved growth of willow plants, namely height, length and amount of all shoots and their freshly harvested dry mass, which were increased by over 25% compared to the controls. The effectiveness of these treatments depended on applied monoculture. The plant spraying with Microcystis aeruginosa MKR 0105 was a little more effective than treatment with Chlorella sp. and Anabaena sp. or the environmental sample. The research demonstrate that the studied Cyanobacteria and Chlorella sp. monocultures have prospective and useful potential in production of Salix viminalis L., which is the basic energy plant around the word. In this work, a special batch reactor was used to produce torrefaction material in an inert atmosphere: nitrogen, thermogravimetric analysis and DTA analysis, like Fourier-transform infrared spectroscopy. The combustion process of Salix viminalis L. with TG-MS analysis was conducted as well as study on a willow torrefaction process, obtaining 30% mass reduction with energy loss close to 10%. Comparing our research results to other types of biomasses, the isothermal temperature of 245 °C during thermo-chemical conversion of willow for the carbonized solid biofuel production from Salix viminalis L. biomass fertilized with Cyanobacteria and Chlorella sp. is relatively low. At the end, a SEM-EDS analysis of ash from torrefied Salix viminalis L. after carbonization process was conducted.

Combustion Processes

Biomass obtained from cultivated energy crops is one of the raw materials with the highest potential in renewable energy production. Although such biomass can be used in production of lignocellulose bioethanol, it is currently mostly used as solid fuel for generating heat and/or electric energy via combustion processes. Calorific values, proximate and ultimate analysis, cell structure and micro- and macro-elements data are considered as basic parameters in the valorization of fuel properties during biomass combustion processes. Energy crops are cultivated with the aim to produce the largest possible quantity of biomass with minimal agro-technical inputs. One of these crops is Sida hermaphrodita (L.) Rusby. Given the fact that the chemical composition of biomass is influenced by a number of agro-ecological and agro-technical factors, the aim of this work was to determine the fuel properties of Sida hermaphrodita biomass obtained from three different harvest seasons (autumn, winter and spring) and cultivated in the area of the Republic of Croatia. On the basis of these investigations it was possible to conclude that harvest delaying towards spring season had a positive impact on suitability of using biomass of Sida hermaphrodita in the combustion process, which primarily means significant lowering the contents of moisture (18.64%), ash (1.94%), and nitrogen (0.65%), but also means increasing the contents of fixed carbon (6.21%) and lignin (25.45%).

Abstract Cultivation of short rotation coppice energy willow (SRC EW), Salix viminalis L., has a great potential in Ukraine as a source of biomass for biofuel production. Commercial production of this species was recently initiated in the country. The growing of SRC EW in Western and Northern Europe for a long time showed that leaf beetles (Coleoptera: Chrysomelidae) are key pests causing significant biomass reduction. However, data about the pest complex for energy willow growing in Ukraine is not available. Our three-year experiment in Poltava region, Ukraine showed that foliar damage caused by Clytra laeviuscula Ratzeburg (Coleoptera: Chrysomelidae) occurred at energy willow plantations in the second year of production, which could have an effect on commercial production. Accordingly, information about seasonal activity, population dynamics, host range and the role of natural enemies in pest regulation are requested for developing pest control program.

The objective of this study was the characterization, analysis and compaction of residues from castor oil plant pie extraction to verify its potential as solid biofuel. The chemical analysis, the mechanical test and the gross calorific value had satisfactory results. With the extraction of residual oil of the material there was a decrease on the high heating value. The produced briquettes presented good longitudinal expansion as well as mechanical strenght, however the presence of residual oil had influence on their strenght. In conclusion, the castor oil plant pie possesses  energetic characteristics suitable for solid biofuel production, in addition it contributes with the reduction of industrial waste amount.

The article describes the quality parameters of the selected elements of biomass as a potential ecological biofuel. Several selected elements of a type of biomass were tested to determine the calorific value, humidity, content of sulfur and amount of ash produced in burning process. The concept of biomass and the legal aspects of its combustion are described. The research of biomass samples revealed that they may be turned into a high-energy, ecologically solid biofuel. Production of biofuel from the tested biomass does not require any additional binders. Studies have shown that the tested material can also act as a component of composite pellets. The quality parameters of such pellets can be determined with the composite calculator that is described in this article. The article also describes the technical aspects of the pellet production line, which should be applied to produce good-quality pellets from the tested types of biomass.

Abstract The aim of this research was to evaluate the physiological activity and growth of willow (Salix viminalis L.) plants cultivated under the conditions of adverse temperature and soil moisture content, and to assess the effect of the foliar application of Biojodis (1.0%) and Asahi SL (0.03%) bio-stimulators, or a mixture of Microcistis aeruginosa MKR 0105 and Anabaena PCC 7120 cyanobacteria under such changing growth conditions. The obtained results showed different reactions to the applied constant or periodically changed temperature and soil moisture content. The plants which grew at periodically changed adverse temperature (from -5 to 40oC) or in scantily (20% m.c.) or excessively (60% m.c.) watered soils, grew slowly, in comparison with those growing at 20oC and in optimally moistened soil (30% m.c.). Foliar application of Biojodis and Asahi SL cyanobacteria increased the growth of willow at optimal and adverse temperature or in scantily and excessively moistened soil. The changes in plant growth were associated with the changes in electrolyte leakage, activity of acid or alkaline phosphatases, RNase, index of chlorophyll content in leaves and gas exchange. The above indicates that the foliar application of the studied cyanobacteria and bio-stimulators partly alleviates the harmful impact of adverse temperature and water stress on growth and physiological activity of willow plants
