Biomass and Bioenergy

On the basis of data a correlation matrix was prepared for the compositions of biomass and enzymatic hydrolysates. As predicted, it was found that there is a positive correlation between the biomass components and the sugars formed from them. Positive correlation occurs between the content of hemicellulose in biomass and achieved concentrations of xylose, galactose, mannose and arabinose as a result of saccharification. Similarly, the concentration of glucose and its dimer - cellobiose is positively correlated. On the basis of the correlation matrix, dendrogram cluster representing the similarity of features was prepared.

This spreadsheet provides the individual datasets used to develop the economic, environmental, and social siting criteria used in the MCDA decision support tool. In some cases, only the output of models used to develop the datasets is provided. Tab 1 provides sample output from the Total Transportation Cost Model to show how the individual biomass source points are routed to a given pulp mill, and the transportation and environmental costs are used to develop the feedstock, environmental, and # of jobs created siting criteria.

The purpose of the present study was to determine selected energy parameters of beech wood affected by four species of white-rot fungi: Grifola frondosa, Hericium coralloides, Meripilus giganteus, and Trametes gibbosa. Wood degradation was studied under laboratory conditions. On days 60 and 120 after inoculation, beech wood samples were analyzed in terms of moisture content, density, elemental composition (C, H, N, S, O), ash content, as well as gross and net calorific value. Reference data were provided by measurements of healthy wood. Elemental analysis indicated small differences in absolute values between healthy and affected wood. White rot led to a slight decrease in C and H and an increase in O. In addition, a significant rise in moisture content was observed (by more than 100%). These factors reduced the net calorific value of healthy beech wood (18.37 MJ/kg) by 0.3 MJ/kg (T. gibbosa) to 0.5 MJ/kg (H. coralloides) after 120 days of the experiment. In terms of the amount of energy contained in a unit of volume, the initial net calorific value of 11.6 GJ/m3 decreased significantly by 18.1% (H. coralloides) to 33.6% (T. gibbosa).
