Phytomass cultivation for energy use is increasingly popular in Europe for high profits guaranteed by subsidy. Although public interest in ecology is on an increasing level, direct combustion is still preferred even though scholars have been warning about formations of hazardous compounds for a long-time. However, the reduction of subsidies would negatively affect an already bad situation in Czech agriculture, since most farmers became fully dependent on subsidies due to quotas, restrictions, and other unequal business conditions in European Union. It (...) was proved in a commercial scale that an alternative phytomass energy utilizing technology consisting of steam explosion and subsequent anaerobic fermentation may be run solely on the waste heat without any further addition of chemicals. Behavior analysis of present and future agriculture decision-makers showed that none of the farmers who visited the facility cared about ecological consequences. On the other hand, ost students from the Faculty of Agriculture and the Faculty of the Economy answered the questionnaire with higher environmental responsibility. We assume this is caused by high average age of farmers in Czech Republic who are more aware of the ongoing economical difficulties and perceive differently the risk of higher acquisition costs.

A new trend in the production technology of solid biof uels has appeared. There is a wide consensus that most solid biofuels will be produced according to the new production methods within a few years. Numerous samples were manufactured from agro-residues according to conventional methods as well as new methods. Robust analyses that reviewed the hygienic, environmental, financial and ethical aspects were performed. The hygienic and environmental aspect was assessed by robust chemical and technical analyses. The financial aspect was assessed (...) by energy cost breakdown. The ethical point of view was built on the above stated findings, the survey questionnaire and critical discussion with the literature. It is concluded that the new production methods are significantly favourable from both the hygienic and environmental points of view. Financial indicators do not allow the expressing of any preference. Regarding the ethical aspect, it is concluded that the new methods are beneficial in terms of environmental responsibility. However, it showed that most of the customers that took part in the survey are price oriented and therefore they tend to prefer the cheaper—conventional alternative. In the long term it can be assumed that expansion of the new technology and competition among manufacturers will reduce the costs. (shrink)
