The SBM (stabiliser of biomass) mechanical plant model is designed for the hydrothermal treatment of biologically degradable materials with using the principle of thermal hydrolysis. The primary task of this equipment is to subject biologically degradable materials to hydrothermal treatment and to recover the materials for a further use or to eliminate them. These entities could use the mechanical plant for economic and environment-friendly methods of handling biologically degradable wastes or materials. The objective of the experiment with various types of biologically degradable materials was to establish the level for the transformation of input characteristics of tested materials after conversion in the SBM mechanical plant and to assess the suitability of the processing by using this method with respect to the use of the final product. Materials tested in the first experiments included stable manure heated or unheated during the processing and maize silage wastes in mixture with wood chips.

This paper presents the results and findings of carbohydrate-content reduction of wooden substances (particles) that are used as filler in cement-bonded particleboards. Several alternatives that appeared as potentially suitable were analysed. The aim of research was to control the carbohydrate level in the wood matter with regards to the reduction of their negative impact on speed and course of the hydration reactions in cement-bonded particleboards. In experimental testing an/the attention was particularly devoted to washout of wood chips by running water and chemical hydrolysis with/by oxidizing agents.

Hybrid Classification

The main contribution of this paper has been to introduce nonlinear classification techniques to extract more information from the PCG signal. Especially, Artificial Neural Network classification techniques have been used to reconstruct the underlying system’s state space based on the measured PCG signal. This processing step provides a geometrical interpretation of the dynamics of the signal, whose structure can be utilized for both system characterization and classification as well as for signal processing tasks such as detection and prediction.

Abstract - There are several problems in storing wood chips freshly harvested from short rotation plantations, which result in quality losses as well as in dry matter and energy losses. The factors influencing the degradation of raw material are examined in this paper with special focus on fungal development. An excessive growth of fungi is connected to dry matter losses and also to an increased health risk during raw material handling. The following factors were measured during 6 months storage of poplar wood chips depending on particle size: box temperature, moisture content, pH-value, appearance of fungi in the storage and the concentration of fungal particles in the air. The results show a close connection between particle size, temperature and attack of fungi. During the storage mesophilic and termophilic species of the genera Alternaria, Aspergillus, Cladosporium, Mucor and Penicillium appeared. The concentration of fungal particles is the highest for fine chips and decreases in bigger particles. There was a special focus on the investigation of the properties of coarse chips (G 50), which represent a good compromise between handling, storage losses and health risk due to fungal development.
