Embodiment Construction

[0035] According to the preamble of this specification, in the ensuing description (description and claims), the term "inorganic substances" refers specifically to substances that cannot be extracted from garbage by pneumatic means (cyclone separators, etc.) after a chemical reaction with quicklime Inorganic matter.

[0036] These inorganic substances include glass, ferrous metals and non-ferrous metals, among others.

[0037] The waste to be processed is preferably domestic waste, which usually arrives at the disposal station after being packed in plastic bags in the receiving area.

[0038] Typically, such a receiving area may consist of a number of metal boxes with a movable bottom, which operate according to the FIFO (First In First Out) principle.

[0039] This waste usually includes both organic and inorganic matter.

[0040] Preferably starting with step 0, in which the garbage bags are sheared and / or ground and / or shredded to obtain pieces with a predetermined partic...

Abstract

A method of treating waste comprising organic and inorganic matter, characterized in that the method comprises the steps of: A) mixing quicklime and at least one strongly hydrating substance with said waste; B) reacting said organic matter to obtain A product comprising a calcium organic complex and said inorganic substance; C) separating said inorganic substance from said calcium organic complex.

Description

technical field [0001] The invention relates to a method for treating garbage. Background technique [0002] From the document WO 01 / 85646 is known a method of treating refuse, wherein the refuse is mixed with quicklime and strongly hydrated substances such as sludge and / or grease from purification stations, the mixture is chemically reacted for a period of time and then ground The dehydrated product from this reaction was crushed. [0003] In the prior art method described above, inorganic matter, which cannot be subsequently extracted by pneumatic means (cyclones, etc.), is extracted from the waste before it is mixed with quicklime and strongly hydrated substances. These pre-extracted inorganic substances include, inter alia, glass, ferrous and non-ferrous metals, and the like. [0004] However, such prior extraction by conventional picking devices is generally not easy. [0005] It should be taken into account that, in practice, the inorganic matter in these wastes ten...
