Abstract:
The present invention relates to a process for restoration of barren land devoid of vegetation or requiring biological recultivation,, wherein the surface of a native ground is covered with a basic layer of semi-liquid recultivation mass prepared on a basis of waste fibrous materials, the layer having thickness of several to several dozens centimeters; in that basic layer there are watering pipes uniformly distributed; after its hardening the basic layer is covered with a top layer of dry mass prepared on a basis of waste fibrous materials, the layer having thickness of several to several dozens centimeters and comprising a hydrogel, adsorbents, as well as plant seeds optionally enveloped with symbiotic mycelium and/or microorganism strains, adjusted to climatic conditions, the character and nature of the native ground, further comprising additives supporting and enhancing vegetation of those plants; and next on the surface of the thus prepared top layer, remaining plant seeds are sown and/or the plants to be cultivated or seedlings thereof are planted; and the degree of wetness of both layers is controlled according to the plants' vegetation phase and climatic conditions prevailing at the recultivated spot of land According to the invention as the additive supporting and enhancing plants' vegetation, there is used a fertilizer in form of cinder(s) and flue gas dust from high temperature process of combustion of pre-segregated and sorted, properly chipped and mixed wastes, in particular municipal wastes, that are unsuitable for a direct use as a soil-forming material, optionally with an addition of very fine grain coal and chemical compounds neutralizing aggressive substances, supplemented with missing nutritive components. The fertilizer is obtained in result of combustion of the above indicated wastes in temperature of minimum 1200°C. The invention relates also to a method for manufacturing a mineral fertilizer, especially for the purpose of land recultivation, in which the properly pre-segregated and sorted, chipped and mixed wastes that are unsuitable for a direct use as a soil-forming material, are subjected to incineration and the thus obtained - and positively verified in the course of respective chemical analysis, cinder(s) and flue gas dust free from any substance adversely affecting natural environment and plants' vegetation are optionally supplemented with missing mineral components, while the heat energy resulting from combustion of pre-segregated and sorted wastes is either utilized directly for the purpose of municipal and/or industrial heating, or cumulated for the future municipal and/or industrial heating purposes.
Abstract:
The invention relates to a process for firing an industrial furnace, in particular for electricity generation, wherein coal or cokes together with a secondary fuel comprising cellulose and plastic, in the form of pellets of a size larger than about 3 mm thickness, and having a caloric value of about 16 GJ/ton or more is ground to a powder wherein about 95 wt% or more has a particle size smaller than 2 mm and wherein the d50 of the particle size distribution is between about 5 and about 100 µm, wherein the powder is injected in the flame of the furnace. In this process the grinding is performed in a roller mill or ball mill, and the amount of pellets used together with the coals preferably is about 3 wt% or more, relative to the coal.

The mixed fuel of sludge and coal with coal as fuel of boiler are fed to the boiler respectively when using the mixed fuel. The ratio of quantity of mixed fuel of sludge and coal to the general quantity of coal for boiler is 20-30%.
Abstract:
A method and system for using plastic material as a fuel includes dissolving the plastic material in biodiesel to form a solution. After the solution is created, it is filtered to remove insoluble contaminants and is then fed to a generator that oxidizes the solution to create power and/or heat. Heat from the oxidation of the solution can be utilized to facilitate the further dissolution of plastic material in biodiesel and to reduce the viscosity of the resulting solution.
