The possibilities to use hydrothermally treated biowaste for air and water cleaning

The aim of the methodology is to provide to farmers, agricultural consultants, biogas plants owners and operators, originators and processors of biowaste, experts in the field of reclamation and recultivation, investors and other interested parties on issues concerned with the basic information on the use of hydrothermally treated biowaste, especially hydrothermally treated residues from anaerobic fermentation for water and air cleaning. In the introduction, the methodology provides a basic overview on literature regarding to coal similar materials, methods for their preparation, especially the way of hydrothermal carbonization, its basic characteristics and its possibilities and perspectives of application in practice. Furthermore, the methodology describes the actual results obtained during the research project usable in practice and provides their agrochemical, environmental and economic evaluation in the case of application at soils. At the end summarizes the main potential applications and uses of new products based on hydrothermally modified residues as essential components of the filter medium for water and air cleaning

Processing of biodegradable waste containing raw materials of animal origin into fertilizer substrates:methodology for practice

The aim of the methodology is to provide to farmers, agricultural advisors, biogas manufacturers and processors, owners and operators of biogas stations and composting plants, investors and other interested parties, the basic information on the possibilities of hygienic treatment at biodegradable waste containing animal raw materials to fertilizer substrates and the ways of their use. The patented combined method of acid and alkaline biowaste treatment ensures a sufficient stabilization and efficient hygiene of the output product, allowing to be further utilized for composting, biogasification, or for soil application as a valuable fertilizer substrate, as well. A part of the methodology is the evaluation of agrochemical efficiency at output use of fertilizer substrates in the cultivation of selected agricultural crops. The methodology is intended for a wide range of users. The methodology can serve as a basis for the adaptation of technical facilities, technological processes and also as a material for teaching at secondary agricultural schools, agricultural universities or agricultural advisors

Products based on hydrothermally treated residues from anaerobic

The methodology aim is to provide the basic information about the products for the soil properties improvement based on hydrothermally treated residues from anaerobic fermentation to the farmers, agricultural consultants, owners and biogas plants operators, also to experts in the field of soil reclamation, investors and to other interested parties on the questions concerned. In the introduction, the methodology provides a basic overview about literary information regarding to coal similar materials, methods for their preparation, especially the methods of hydrothermal carbonization, their basic characteristics, possibilities and perspectives for their application in practice. Furthermore, the methodology describes the own results obtained during the research project usable in practice and provides their agrochemical, environmental and economic evaluation. The conclusion gives an overview of the potential application and the main use possibilities of the new products based on hydrothermally treated residues from anaerobic fermentation for the soil properties improvements and in particular for common agricultural fertilization and anthropogenic soils

The possibilities to combine biogas production and biowaste hydrothermal carbonization

The objective of the methodology is to provide to farmers, agricultural consultants, owners and operators of biogas plants, to biowaste producers and processors, to experts in the field of soil reclamation and melioration, to investors and other interested parties on the concerned issues, the basic information about the potential at the combination of biogas production and biowaste hydrothermal carbonization. These options are evaluated on the basis of processing at accumulated energy intensity for the above combined processes and its comparison with conservative biogas production using the example biogas plant with installed electrical capacity of 800 kW. Part of the methodology is guided to evaluate the potential use of thermo- pressure hydrolysis unit as a device for digestate hydrothermal carbonization and other wastes in order to improve their performance, particularly in terms of employment in agriculture as highquality substrates for soil fertilization and for the purpose of soil carbon sequestration

Preservative for ensilage of excessively wet plants intended for biogas

The methodology objective is to provide to farmers, agricultural consultants, operators of agricultural biogas plants, workers in research and agricultural education as well as all other interested parties on agricultural biomass cropping and processing as a renewable source of raw materials and energy, the basic information about a new preservative for ensilage of excessively wet plants intended for biogas production. The publication reports on the development and testing of a new preservative for phytomass ensilage destined for biogas production, especially of excessively wet plants. Its use in practice can provide a cost-effective reduction of organic wet matter losses, increase silage quality and also increase the production of biogas
