The data presented herein suggested that the amount of smoke in the burning process can be better suppressed after the cotton fabric finishing with built-up system was burnt. Some general principles were identified, and the likely causes of the observed effects were analyzed according to test data.展开更多

This research aims to identify the key factors that influence consumers＇ choice to buy organic food products in Lithuania focusing on the consumer trust in the quality and the most acceptable marketing channels. In order to get the necessary information, the residents of Vilnius （the capital of Lithuania）, as having the greatest potential for the organic food market in the country, were interviewed. The analysis of collected data was done using the methods of mathematical statistics and comparison of relative frequencies. The results of this research prove the increasing consumers＇ interest in organic food products. The majority of consumers consider these products to be healthier, better-tasting and fresher. Only about a third of the purchasers （usually buying frequently） can see differences between organic and non-organic products, therefore, there is a problem to distinguish organic food from conventional products and, consequently, remains a possibility to cheat the consumer. An additional quality control and direct sales from known and familiar farmers might increase trust in the quality of organic food products. So far, supermarkets are the most important place to buy organic foods, however, the greater consumer confidence in the quality of organic products bought at farmers＇ markets and the acceptance of the majority of purchasers to buy organic food products directly from the farmers suppose the need to develop a direct marketing system.展开更多

In Brazil, organic farming is one of the most established initiatives in this area. Therefore, it is important to subsidize the decision-making regarding policies for organic coffee production. Thereby, this study analyzed the socio-economic sustainability of this production system in relation to conventional. We applied a semi-structured questionnaire on coffee farms in the Brazilian coffee producers states and analyzed the coffee production cost structure. We identified the reasons that led the producers to organic management, implications of certification on the management, and prices received by organic coffee and the market mechanism. Results showed that there is no standard for organic coffee production and marketing in Brazil. Among the producers, there are different levels of access to technical information and the main limitation of the organic coffee chain is not the technology of production, but the difficulty of coffee marketing. Another important limitation, for medium and large farms, is the cost of manpower, mainly in areas dominated by mountain, where machines operations are not viable. Moreover, the yield of organic coffee system is generally lower than the conventional. Furthermore, soil and climatic differences lead to different regional behavior. Finally, we could conclude that the production of organic coffee can be sustainable in Brazil mainly in two structural conditions： 1） family farmers; and 2） small producers, who employ only one or two workers, preferably only in the harvest time.展开更多
