This book presents the results of a comparison of the quality of food products and raw materials, such as vegetables, fruits and honey, produced in organic and conventional farming systems. The comparison, which was based on literature data and the results of our own research, included not only the chemical parameters important for assessing the nutritional and health-promoting values, but also the stability of the ingredients in the fruits, which is important from a food storage perspective. The ecological, social and economic aspects of organic food production, which are crucial from the perspective of sustainable development, are also discussed in the book.

Organic Versus Conventional Farming aims at academics and farmers, but also to anyone looking for the answer to the question of whether organic farming ensures high-quality food, the production of which is safe for the environment.

Advances in Renewable Energy Research comprises papers delivered at an international workshop by authors from Poland, Germany, Ukraine, China, Japan and Taiwan. The papers discussed the development of renewable energy technologies in certain countries, with special attention deviated to the conducted scientific research.

The greatest attention was paid to the use of biomass, which uses resources that are readily-available in large quantities in all countries. The experience related to the use of biomass for energy generation was presented for certain countries, i.e. Germany and Japan as representatives of the most advanced countries in the field of energy generation from renewable sources, Taiwan and Poland, which have some experience in that area as well, and China and Ukraine, which have just started the introduction of renewable energy technologies. The greatest attention was devoted to the biogas production methods, i.e. chemical, biological, and mechanical pre-treatment methods, as well as enhancement of anaerobic fermentation and purifi cation of the biogas produced. -The development of solar (photovoltaic and thermal) methods and the use of heat pumps in residential buildings are also discussed, mostly with Polish experience asan example. Special attention is paid to research methods to be used for development of renewable energy technologies.

Advances in Renewable Energy Research is useful for engineers and researchers working in the renewable energy area.

Biomass is a widely available resource, that can be characterized by its high production potential. Enabling the production of different types of biofuels, biomass can be used in both spark-ignition and compression-ignition engines. There is extensive knowledge of the biofuel production process, and technologies enabling the production of biofuels with high caloric value and better physicochemical properties are developed. The biggest barrier in the development of a biofuels market is not the lack of know-how, but economic and political aspects.

Biomass for Biofuels presents technological aspects of biomass conversion into advanced biofuels. Also discussed are the influence of growing biofuels markets on the natural environment and social relations as well as economic aspects of acquisition of biomass and its processing into biofuels. In addition biomass characteristics are presented. A definition is provided, and its chemical composition and properties detailed. The focus is on lignocellulosic biomass, whose complex structure is a limiting factor for biofuels production via biological processes. For that reason, echanical, chemical and physicochemical methods that enable an increased availability for the microorganisms used for biomass conversion to biofuels are discussed.
