The possibilities to use biochar-based fertilizing substrates from combined hydrothermochemical treatment of contaminated biowastes
Usťak, Sergej ; Muňoz Jans, Jakub ; Váňa, Vojtěch
The methodology aim is to provide the basic information about fertilizing products for improving soil properties based on combined hydrothermochemical treatment of biowaste, including contaminated ones (especially sewage sludge) to the farmers, agricultural advisers, owners and operators of wastewater treatment plants (WWTPs) and biogas plants (BGP), experts in reclamation and amelioration field, investors and others 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 biowaste hydrothermochemical carbonization, including contaminated ones, as well as an overview about their basic properties and especially the possibilities and perspectives of application in practice. Furthermore, the methodology describes the results obtained during the solution of the research project that are usable in practice, and it provides their agrochemical, ecological and economic evaluation, too. Finally, it is provided an overview of the potential and main possibilities to apply the new fertilizers based on biowaste hydrothermochemical treatment, including contaminated ones, for improving soil properties and especially for the fertilization of common agricultural and anthropogenic soils.

Processing of biodegradable waste containing raw materials of animal origin into fertilizer substrates: methodology for practice
Usťak, Sergej ; Muňoz, Jakub ; Váňa, Vojtěch
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.

Preservative for ensilage of excessively wet plants intended for biogas
Usťak, Sergej ; Muňoz, Jakub ; Jambor, Václav
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.

The possibilities to combine biogas production and biowaste hydrothermal carbonization
Usťak, Sergej ; Honzík, Roman ; Muňoz, jakub
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.

The possibilities to use hydrothermally treated biowaste for air and water cleaning
Usťak, Sergej ; Muňoz, Jakub ; Usťaková, Marie
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.
