Using biomass to produce energy is not a new idea. In the past, the by-products of energy(?) production processes or naturally grown materials were mainly used for energy production. At the same time, during the production of biomass the conventional sources of energy are used (fuels, the embodied energy of which is used in the production of th...e biomass and equipment, etc.) which must be taken into account when determining the net energy production. This research aims to examine how to optimise the production and use of biomass energy and its supply chain in the energetic and economic criteria system, as well as how to impact upon the managing models of the processes to the energetic and economic parameters of the supply chain; we ask what criteria characterise the natural (environmental), economic and social sustainability, and how they can be implemented e.g. within the framework of an innovation cluster. This article describes a test model, and analyses the results of the model examinations and the conditions for compliance with sustainability criteria. Arguing the environmental, economic and social sustainability among the criteria of the model for evaluation is not possible at all times by means of direct indicators. The results of the research proved that only multi-criteria optimisation models serve a proper decision-making instrument for the evaluation of biomass utilisation for energy production.
Local socio-economic cooperation arrangements can contribute to the development of adequate solutions which can compensate the negative impacts of globalization. One of the specific areas is agriculture. Capital-intensive technology is the key element in the competitiveness and viability of firms. The present paper reviews the factors affecting... the joint machine use arrangements of agricultural producers, with special regard to the role of trust. The questions of trust are examined in two dimensions: contractual and competence trust. On the basis of the survey carried out among farmers a positive connection was detected between the level of trust and the farmers’ activity in cooperation arrangements. Our results also pointed out that the trust needed in different areas of cooperation is very different. The experiences indicate a tendency, according to which contractual trust is more important in intensive cooperation arrangements which result in higher dependence, while competency trust is more emphasized in more extensive solutions.
