“…For the preparation of biofuel from herbaceous energy plants, chopping and milling quality of these plants should satisfy the requirements for the combustion chamber, chopped mass transportation machinery and storage. For the first step of stem chopping we used a drum chopper in a Maral 125 forage harvester [11]. Before the production of biofuel pellets, the prepared chaff should be chopped to the form of the mill.…”

“…Usually, during the third year, plants grow to approximately 3 m high and may give a good harvest. The harvest of elephant grass biomass depends on soil moisture, and thus crop watering will give a harvest surplus in almost every year [11]. With favourable growth conditions and sufficient soil moisture, elephant grass may grow up to 25 t ha -1 of dry material.…”

Three unconventional herbaceous energy plants -sida (Sida hermaphrodita Rusby), elephant grass (Miscanthus giganteus) and reed canary grass (Phalaris arundinacea) -were grown and investigated in the experimental fields of Aleksandras Stulginskis University, and the technical means of plant preparation and usage for energy purposes were investigated. The physical-mechanical characteristics (moisture content, density, flow angles) of chopped and milled unconventional energy plants were investigated. These characteristics are required to project and choose the supply, transportation and storage equipment. In evaluating the quality of plant chopping and milling, the fractional compositions of reed canary grass, sida and elephant grass chaff as well as the mill were determined. The largest chaff fraction was found in a sieve with 8-mm diameter holes (from 52.0 to 62.7%), and the largest mill fraction was found in a sieve with 0.5-and 0.63-mm diameter holes (from 37.6 to 46.4%). The pellet moisture content was sufficiently low and varied from 6.7% to 9.6%. The highest density was determined in reed canary grass pellets (1035.1±63.9 kg m -3 DM), and the lowest density was in elephant grass pellets (653.6±67.1 kg m -3 DM). The emission of harmful gases was determined when various unconventional energy plants were burned. The highest concentration of carbon monoxide (CO) was observed when burning elephant grass (2294.7 ppm), and the smallest concentration of CO was observed when burning reed canary grass (905.2 ppm). The most carbon dioxide was detected when burning sida (7.9%), and the smallest when burning elephant grass (5.2%). The nitrogen oxide emissions differed only insignificantly; the values ranged from 176.2 ppm (Reed canary grass) to 216.1 ppm (Elephant grass). a prime cost of 0.12 EUR/kg. When energetic grasses were dried using dispergation, the primary cost increases to 0.13 EUR/kg.

“…The model of Jasinskas et al (2008) who modeled the changes of moisture contents of energy crops during the natural drying was used to describe the drying of pea shells as follows: The experimental data were used to calculate the model parameters. The calculated values of a and b together with the determination coefficient (R 2 ) are shown in Table (3).…”

Drying of biomass is important to assure a year round supply of a certain feedstock and to minimize the loss of organic matter during storage. Egypt produces about 0.15 million ton of pea shells annually that can be used for the production of biofuel, compost and other valuable products. The main objective of this study was to study some physical properties (i.e., mass of an individual shell, bulk density, particle density and porosity) that affect the design of handling and processing equipment of this feedstock. Another objective was to determine the sun-drying time required to reach a moisture content at which it is possible to safely store pea shells without the loss of organic matter and without jeopardizing the feedstock to self ignition and spoilage by microorganisms or fungi. Sun-drying experiments were conducted during March 2008 under El-Mansoura weather conditions. The effects of drying tray type and the initial mass loading per unit exposed area on drying time were studied. Drying was carried out using galvanized screen and particleboard trays at three initial mass loadings of 2, 4 and 8 kg [shells]/m2. The results showed that the average weight of an individual shell was 2.11 (±1.11) g. High correlations were found between moisture content and each of the studied physical properties. The particleboard drying trays showed relatively higher drying rates than the screen trays. Drying curves were well described by an exponential function. Most of drying occurs in the falling rate period. Higher drying rates were observed under the lower initial mass loading than the higher mass loadings. It was possible to obtain a moisture content of about 20% (w. b.) after sun-drying the shells for 2.3 days at an initial mass loading of 2 kg/m2. To obtain a comparable moisture at the initial mass loadings of 4 and 8 kg/m2, shells should be dried for about 4 days.

“…The statistical data method of estimation involves subtracting the amount of resources used for other purposes and the amount of each possible type of biomass that can be used for bioenergy production, as well as the losses incurred in the process of collection, transportation, etc. The amount remaining is multiplied by the energy conversion coefficient and converted into a unit of energy [38,39]. As new methods, RS and GIS are mainly used to estimate biomass energy potential and obtain land area information for biomass cultivation.…”

The Beijing-Tianjin-Hebei region has abundant biomass resources, which are difficult to collect and thus are underutilized. However, the potential estimation of biomass energy can result in a comprehensive understanding of bioenergy resources in order to establish a technology roadmap for the region’s bioenergy development. Therefore, it is essential to estimate the potential of Beijing-Tianjin-Hebei biomass resources and bioenergy utilization. In this paper, the amount of main biomass resources for possible energy use and bioenergy utilization are calculated based on a statistical data estimation method for crop residues; human, poultry, and livestock manure; and municipal solid wastes. On the basis of biomass resources and bioenergy utilization potential, the technology roadmap is established. The results show that the amount for available biomass energy use is unevenly distributed in the Beijing-Tianjin-Hebei region, and the largest amount of resources is crop residues (36.52 million tons or 18.26 million tons coal equivalent). The biogas from human, poultry, and livestock manure and densified solids from crop residue technology roadmap is suitable for the Beijing-Tianjin-Hebei region.
