Recycling of products
View Patent ↗The invention relates to a process for the production of a recyclable product ( 1, 8, 9 ) made from a first material, wherein before or during the production of the product ( 1, 8, 9 ) a first marking material is added to the first material and the product ( 1, 8, 9 ) is produced from the first material with the admixed marking material, wherein the first marking material can be automatically detected in a recycling plant in the first material of the product ( 1, 8, 9 ) after the production thereof. The invention also relates to a process for the recycling of a product ( 1, 8, 9 ), wherein the product ( 1, 8, 9 ) is manufactured from a first material, to which a first marking material is added, wherein the product ( 1, 8, 9 ) or pieces ( 22 ) of the product ( 1, 8, 9 ) are separated from one another and/or from other objects in a recycling plant, in that the first marking material is detected in the first material of the product ( 1, 8, 9 ) or the pieces ( 22 ) of the product ( 1, 8, 9 ), and the product ( 1, 8, 9 ) or the pieces ( 22 ) of the product ( 1, 8, 9 ) are separated from one another and/or other objects, in which no marking material or a different, second marking material is detected. The invention also relates to a recyclable product and a recycling plant.
1. A process for the production of a battery, comprising:
manufacturing a housing of the battery using a first recyclable polymeric material that includes a first marking material;
manufacturing a plurality of separators of the battery using a second recyclable polymeric material that includes a second marking material, wherein the first and second recyclable polymeric materials are the same recyclable polymeric material, wherein one of the first or second marking materials is a photoluminescent material and the other of the first or second marking materials is a magnetic material or electric microcoils that are detectable and distinguishable from the photoluminescent material during recycling of the battery, and wherein the first and the second recyclable polymeric materials each comprise polypropylene; and
sealing a plurality of electrode plates of the battery into an interior of the housing, wherein at least a portion of at least one of the plurality of separators is disposed between each of the plurality of electrode plates in the interior of the housing.
2. The process of claim 1 , comprising admixing the first marking material to the first recyclable polymeric material and admixing the second marking material to the second recyclable polymeric material.
3. The process of claim 2 , wherein admixing the first marking material to the first recyclable polymeric material comprises substantially evenly distributing the first marking material within the first recyclable polymeric material.
4. The process of claim 1 , wherein the first marking material is the electric microcoils.
5. The process of claim 4 , wherein the electric microcoils consist essentially of carbon and absorb high-frequency electromagnetic radiation.
6. The process of claim 5 , wherein the second marking material is the photoluminescent material.
7. The process of claim 1 , wherein the first and second recyclable polymeric materials comprise a co-polymer of polyethylene and polypropylene.
8. The process of claim 1 , wherein the first and second recyclable polymeric materials comprise polypropylene filled with a filler material, the filled polypropylene having a higher density than unfilled polypropylene.
9. The process of claim 1 , wherein the first marking material is the photoluminescent material and the second marking material is magnetite powder.
10. The process of claim 1 , wherein the first marking material is the photoluminescent material and the second marking material comprises iron filings.
11. The process of claim 1 , comprising manufacturing at least a third component of the battery using a third recyclable polymeric material that does not include a marking material, and wherein the third recyclable polymeric material comprises filled polypropylene and the first and second recyclable polymeric materials comprise unfilled polypropylene, or the third recyclable polymeric material comprises unfilled polypropylene and the first and second recyclable polymeric materials are filled polypropylene.
12. The process of claim 1 , wherein the plurality of separators comprise a plurality of pocket-shaped separators, and wherein each positive electrode plate of the plurality of electrode plates is disposed inside each pocket-shaped separator of the plurality of separators.
13. The process of claim 12 , wherein the plurality of separators protrude in height above the plurality of electrode plates within the interior of the housing of the battery.
14. The process of claim 12 , wherein the battery is a starter battery for a motor vehicle.
15. A method of manufacturing a starter battery for a motor vehicle, comprising:
admixing a photoluminescent marking material to a first polypropylene material;
admixing a second marking material to a second polypropylene material, wherein the first polypropylene material and the second polypropylene material are the same polypropylene material and the second marking material is magnetic marking material or electric microcoils; and
manufacturing a housing and a separator of the starter battery using the first and second polypropylene materials, wherein one of the housing and the separator is manufactured from the first polypropylene material and the other of the housing and the separator is manufactured from the second polypropylene material.
16. The method of claim 15 , wherein the housing is manufactured from the first polypropylene material and the separator is manufactured from the second polypropylene material.
17. The method of claim 15 , wherein the housing is manufactured from the second polypropylene material and the separator is manufactured from the first polypropylene material.
