Abstract:

The paper focuses on showing variability of knowledge and demand for organic food in two regions of Poland, i.e. Świętokrzyskie and Mazovian provinces. The selected for detailed investigations Polish regions differed in society wealth. Mazovia province with capitol (Warsaw) is reach as opposed to Świętokrzyskie – mountain province with dominance of more difficult conditions for comfort and affluent life. Basing on questionnaire the group of respondents’ attitude towards organic food was recognized and compared. The problems included in the questionnaire there were factors influencing the organic food buying, factors which influence about the resignation of organic food buying, the availability of information about organic food, availability of organic food in selected regions, requirements for organic food, most frequently purchased organic products, place where consumers buy organic food, consumption frequency of organic food, factors influencing the choice of organic food. The comparison of two provinces indicated differences within the meaning of organic food as well as autonomy in consumer behaviour. Polish society is characterized by a growing interest in organic food. The production industrialization and mass food processing causes people to look for some alternatives. Organic farming gives people that chance. In the conclusions, we have formulated a term mean that due to the consumption of organic products – ‘we are what we eat’.

Abstract:

Charcoal is a well-known material obtained through thermal conversion of different types of biomass in an anoxic environment. The greatest share of the overall charcoal amount is produced in inefficient batch pyrolysis chambers. Thus contribution in an in-depth charcoal production process research for process optimization is of great importance. In this study an industrial experiment of charcoal production in a continuous up-to-date retort is performed. The selected industrial object has a high level of automation and process control. The retort is connected to a continuous monitoring system that records and stores the process parameter values. Apart from the process control parameter measurements attention has to be paid to the charcoal production plant pollution as this industry often gets contradictory attention towards its environmental performance. The air pollution is evaluated by air quality measurements at the production facility site. The obtained experimental results from an industrial facility with a state-of-the-art technology give an opportunity to evaluate the potential of the charcoal industry to be a sustainable player in the renewable energy market.
