Abstract:
The present invention is directed towards an apparatus and method for harnessing energy from waste materials (102) using a pyrolysis assembly, whereby the pyrolysis assembly comprises a pre-pyrolysis treatment plant (104), a pyrolysis plant (120), and, a fuel-based energy plant(136). Waste materials having at least 30% biomass by weight are fed into the pre-pyrolysis treatment plant and the biomass is separated from the waste materials in the pre-pyrolysis treatment plant. The biomass is chemically cracked into at least a char and a gas in the pyrolysis plant and this char and gas is used by the fuel-based energy plant to harness energy from the waste materials. Problems associated with the efficiency of pre-pyrolysis treatment plants and safety of the parts used in the pre-pyrolysis treatment plants is addressed in the current invention
Abstract:
The invention relates to a method and apparatus for producing a pyrolysis product, in which raw material are fed to the pyrolysis reactor and gaseous pyrolysis product fractions and by-product fractions are formed from raw material by pyrolysis in a pyrolysis reactor. According to the invention the method comprising steps: combusting at least one by-product fraction from the pyrolysis reactor in at least two combustors, and recovering energy formed in the combustor.
Abstract:
A system for treating infectious waste is provided that employs a medical waste handling and shredding sub-system that feeds partially processed waste to an oxidizer to eliminate potential airborne infectious waste prior to transforming the medical waste into useful co-products. Medical waste is transformed into value added products including hydrocarbon based gases, hydrocarbon-based liquids, carbonized material, and recovered precious metals and rare earth materials in a system having as its transformative element an anerobic, negative pressure, or carbonization system. With medical waste as a feedstock for the production of valuable products, an economically viable and environmentally more responsible alternative to traditional methods of medical waste treatment is realized.

Abstract:
A method for production of electricity and heat in a process of thermal conversion of different types of wastes in an integrated installation, wherein different types of wastes (101-109) are segregated to separate wastes destined for thermal disposal (124, 132, 133, 134, 135), which are then processed in at least two mineralisers (139, 140, 141), each having a form of an isolated, longitudinal, rotatable and inclined tube (200) with vanes (205-210) arranged on its internal walls to scatter the material during the rotation of the tube (200), characterized by performing periodic measurements to determine calorific value, moisture content and composition structure of the wastes intended for thermal disposal (124, 132, 133, 134, 135) by using analysers (114, 118, 122, 127, 129, 131). Using rotary mineralisers (139, 140, 141) that comprise in the mineralisation zone (230) vanes (205-210) with adjustable angle of inclination to the longitudinal axis of the mineraliser tube (200), so that during the operation of mineraliser, for larger inclination angles of vanes (205-210) the batch material passes faster through the mineralisation zone than for smaller inclination angles of vanes (205-210). By using mixers (136, 137, 138) assigned to the mineralisers (139, 140, 141), the wastes (124, 132, 133, 134, 135) are mixed with each other in proportions dependent on the predetermined amount of chemical energy of the batch material and on the inclination angle of vanes (205-210) set in the particular mineraliser (139, 140, 141), so that for a mineraliser (139, 140, 141) having a larger inclination angle of vanes (205-210) a mixture with a higher calorific value is selected than the calorific value of mixture for a mineraliser (139, 140, 141) having a smaller inclination angle of vanes(205-210). The rotational speed of each mineraliser (139, 140, 141) is adjusted according to the moisture content of the mixture provided to the particular mineraliser (139, 140, 141).
