Definitions
- the LCD is refurbished and the individual components are recycled for the original product (eg reprocessing of the liquid crystals or the glass and their use for the production of new LCD 's ).
- the LCD is refurbished and the individual components are used in other industries or for other products.
- Individual components, preferably removed components, of the LCD 's are energetically utilized. In this case, for example, the combustion of plastics is used to generate energy.
- a disadvantage of this method is that the separation the liquid crystals, which account for only a very small proportion by weight of the entire display (about 1 kg of liquid crystals per tonne of displays) and on the other hand constitute a mixture of a variety of different individual substances, both technically and financially very complex, especially the liquid crystals then be deposited.
- a use of the recovered liquid crystals in new LCD 's is uneconomical in the current state of the art. This also applies to another method for the extraction of liquid crystals with solvents, which is described in JP 2002/126688 A.
- plastics such as housing parts but also polarizing films and other films, are generally separated and either energetically utilized or find use for other products.
- the thermal recycling of such plastics is e.g. in JP 2002/159955 A.
- the finished material is similar to the known expanded clay from hydroponics and can be used as a lightweight aggregate, as a filler, as a thermal insulation material, as a carrier Granules or as absorbent material in the construction industry, in gardening and landscaping as well as in wastewater engineering.
- JP 2001/296508 A and JP 2001/296509 A Other methods for removing the polarizing film by mechanical removal, combustion or gasification, followed by comminution of the glasses and their use as a glass replacement are described in JP 2001/296508 A and JP 2001/296509 A.
- the disadvantage of these methods is that the glasses obtained therefrom are heavily contaminated and vary greatly in composition. That's why they can only be used for substandard applications.
- JP 2000/084531 A discloses a process for recycling LCD ' s described, in which the LCD ' s are first crushed, on particle sizes of less than 10 mm. Subsequently, the thus comminuted particles are used at 1200 ° C in melting furnaces for the removal of iron.
- a disadvantage of this process is particularly time-consuming comminution of the LCD 's to particle sizes of less than 10 mm and the restricted application to the removal of iron.
- the present invention thus provides a process for material recycling of LCDs, which is characterized in that the LCD 's are at least partially, preferably completely, used as a replacement for other raw materials.
- the LCD 's are employed in a temperature range of 900 to 1700 ° C, preferably 1000 to 1400 ° C, and particularly preferably 1,200 to 1,400 ° C, thermally treated. The thermal treatment takes place in particular at temperatures above 1200 ° C, and thus at temperatures at which even high-quality borosilicate glasses melt.
- An LCD in the present application is understood to mean a display which, in addition to the two glass plates, at least still contains the materials arranged between the two glass plates, e.g. Liquid crystal, transparent films and adhesives, and may include electronic components (e.g., electrodes) connected to the display.
- the plastic housing, the backlighting and optionally the polarizer films are usually previously separated and recycled separately. However, they can also be used directly in the process according to the invention.
- LCD's consist essentially of from 30 to 99.8 weight .-% of glass and 0 to 60 wt .-% of plastic film, as well as 0.1 to 20 wt .-% of electronics and liquid crystals.
- inventive method as LCDs preferably used LCD are 's and LCD' s use of the committee from production.
- the treatment of LCD is 'supply of energy from energy sources such as gas, coal and oil, and / or taking advantage of s in the LCD' s existing heating understood in the present application.
- the thermal treatment is usually carried out in thermal treatment plants, such as
- the LCD 's can be used without crushing.
- An advantage of this embodiment is that can be dispensed with the crushing of the LCD ' s, which is associated with both an additional technical effort and with additional costs.
- the LCD 's are crushed.
- the type and size of the crushing is not critical. So the LCD 's can either be broken, shredded or ground. Depending on the type of comminution, the average size of the fragments is in the range of decimetres (when breaking), in the range of centimeters (when shredding) and in the range of millimeters (when grinding).
- An advantage of the method according to the invention is that the complicated separation of the liquid crystals is superfluous and at the same time the risk of the formation of toxic products, such as dioxin, is avoided because at the high temperatures of the process according to the invention all organic products are destroyed.
- Another advantage of the method according to the invention is that the starting material can be used in ground, shredded, broken and / or uncomminuted form.
- the process according to the invention is an economical process, in which, in addition, a material and optionally additionally at least partial thermal utilization of the LCDs takes place.
- the material according to the invention as well as the optionally additional, at least partial thermal utilization can be carried out in various preferred embodiments.
- the LCD 's in a temperature range of 900 to 1400 ° C, preferably 1200 to 1400 ° C selectively melted.
- the glass is recovered in a pure form, although partly as a mixture of soda lime glass and borosilicate glass.
- the metal parts originating, for example, from the electrodes settle and can be separated from the molten glass.
- the products obtained in this way are used in the building materials industry or in road construction, for example as insulating material or as blown material.
- the LCD's with other metal-containing products such as metal-containing slurries and / or catalysts, mixed and thermally treated in a temperature range of 1200 to 1400 ° C, preferably 1250-1350 ° C.
- the proportion of LCD ' s in the total mixture is preferably in the range of 5 to 50 wt .-%.
- the LCD 's are used to bind and separate from the noble metals contained in the metal-containing products base metals such as iron, lead, zinc and tin.
- the precious metals in the present application include both the noble metals in the strict sense, such as gold, silver, platinum, mercury, rhenium, ruthenium, rhodium, palladium, osmium and iridium, as well as the semi-precious metals nickel, copper and cobalt.
- the mixture is preferably melted in crucibles, melting furnaces or rotary kilns and then poured into crucibles. After cooling, the melt is broken.
- the lower part contains metal and essentially contains the noble metals, whereas the upper part contains the slag with the base metals.
- the part containing the noble metals is supplied to the metal recovery, and the slag containing the base metals is used in road construction, for example.
- the advantage of this embodiment is its cost, because the LCDs replace in this embodiment, at least a part of the conventionally used melting sand, which must be necessarily added in this process to the base metals to bind.
- at least a portion of, preferably all, electronic components of the LCD ' s are used, since as stated above, a separation and recovery of at least the precious metals takes place.
- Another significant advantage is the high energy input through the plastic films contained in the LCD 's . This should be proven by the following calculation:
- 1 ton of LCD 's is composed of:
- the calorific value for PE film is 46,000 kJ / kg. With 150 kg of plastic film, this results in a calorific value of 6,900,000 kJ.
- the energy requirement to melt 1 kg waste glass is in the range of 3,000 to 6,500 kJ. Accordingly, 2,490,000 to 5,395,000 kJ are required to melt 830 kg of glass.
- the calorific value of the plastic films exceeds the energy required to melt the glass, i. that even a Kunststoffstof fanteil of 15 wt .-% is sufficient to melt the LCD glass. Consequently, theoretically, no additional energy requirement is necessary.
- the energy input also increases with increasing plastic fan part, advantageously by entry of the plastic housing.
- plastic films contained in the LCD ' s can be used as a reducing agent to reduce the metal-containing products.
- carbonaceous products such as coal
- Reducing agents oxidizes the metals and would have to be reduced to metals in an additional production step again.
- Reducing agents oxidizes the metals and would have to be reduced to metals in an additional production step again.
- the LCD ' s as raw and / or aggregate in rotary kilns in a temperature range of 1100 to 1300 ° C, preferably 1150 to 1250 ° C, thermally treated.
- the thermal treatment of the LCD 's in rotary kilns leads to the formation of a protective film on its inner liner.
- the proportion of the LCD 's lies as raw material and / or aggregate in the Total charges composition preferably in the range of 1 to 20 wt .-%.
- Rotary kilns generally have a chamotte lining that is attacked by aggressive gases and materials when incinerating industrial waste. Consequently, these chamotte stones must be renewed at regular intervals.
