Procedures for the disposal and recycling of plastic waste and disposal system

Abstract

Method for the disposal and recycling of plastic waste arising from processing machines, wherein an empty receiving container for the plastic waste arising from the processing machine is arranged on each of the processing machines, which empty receiving container is filled with the plastic waste during operation of the processing machine, wherein each of the receiving containers is provided with the data identifying the plastic waste received therein and wherein the filled receiving containers are transported to a recycling facility and emptied, characterized in that each of the receiving containers is provided with the data identifying the plastic waste received therein directly on the processing machine.

Description

[0001] The invention relates to a method for the disposal and recycling of plastic waste and a disposal system for plastic waste.

[0002] Examples of recycling processes are known from DE 198 20 743 A1 and DD 2 60 827 A3.

[0003] Industrial plastic waste is typically collected at the factory where the plastic processing machines are located and placed in transport containers for transport to a recycling facility. There, it is fed into appropriate recycling machines and processed into new plastic raw materials. These are generally of inferior quality because plastic waste of different materials is regularly collected and mixed in the transport containers, and this mixture of materials is fed to the recycling machines. Separating plastic waste into different types before recycling is extremely complex and unprofitable.

[0004] It is therefore an object of the invention to develop a method for the disposal and recycling of plastic waste and a disposal system with which a higher quality of the raw material resulting from recycling is achieved.

[0005] This object is achieved according to the invention by a method having the features of claim 1 and a disposal system having the features of claim 7. Advantageous developments of the invention are the subject of the dependent claims.

[0006] The invention is based on the idea of ​​filling the plastic waste generated at a processing machine directly into receiving containers at the processing machine and labeling these containers according to their contents. Since plastic processing machines generally only process one type of plastic, this achieves a highly pure separation of the waste so that it can also be recycled separately according to type. For this purpose, the data characterizing the plastic waste contained in the respective receiving container is advantageously read out at the recycling facility, and the respective receiving container is assigned to a recycling machine that is equipped to recycle the plastic waste it contains. To avoid errors, each receiving container is advantageously filled with plastic waste at only one processing machine before being transported to the recycling facility.This ensures that the plastic waste contained in this receptacle all comes from one processing machine and is highly sorted.

[0007] It is advisable to print a label on at least one of the processing machines using a printer to identify the plastic waste filled into the respective receptacles. Advantageously, such a printer is located on each processing machine. However, it is also possible to provide pre-printed labels on at least one of the processing machines to identify the plastic waste filled into the respective receptacles. The labels printed or provided on the processing machine can be affixed to the receptacles, inserted into slots on the receptacles, or simply placed in the receptacles.

[0008] The disposal system according to the invention serves in particular to carry out the method described above and comprises a plurality of receiving containers for the plastic waste. It also comprises a marking device on each processing machine for marking the plastic waste received in the receiving containers and transport means for transporting the receiving containers. Finally, it comprises a recycling device for processing the plastic waste transported by the receiving containers, which preferably comprises several recycling machines configured for recycling different types of plastic waste.

[0009] In summary, the invention relates to a method for the disposal and recycling of plastic waste generated at processing machines, wherein an empty receiving container for the plastic waste generated at the processing machine is arranged at each of the processing machines, which container is filled with the plastic waste during operation of the processing machine, wherein each of the receiving containers is provided with the data identifying the plastic waste received in it and wherein the filled receiving containers are transported to a recycling facility and emptied.

Claims

[1] A method for the disposal and recycling of plastic waste generated by processing machines, wherein an empty receptacle for the plastic waste generated by the processing machine is arranged on each of the processing machines, which is filled with the plastic waste during operation of the processing machine, wherein each of the receptacles is provided with the data identifying the plastic waste received in it, and wherein the filled receptacles are transported to a recycling facility and emptied, characterized by that each of the receiving containers is provided directly at the processing machine with the data identifying the plastic waste it contains. [2] Method according to claim 1, characterized bythat the receiving containers, at least in some of the processing machines, are each arranged on a material ejection device from which the plastic waste falls directly into the respective receiving container. [3] Method according to claim 1 or 2, characterized by that each receiving container is filled with plastic waste only at one processing machine before being transported to the recycling facility. [4] Method according to one of the preceding claims, characterized by that the data identifying the plastic waste contained in the respective receiving container are read out at the recycling facility and that the receiving container in question is assigned to a recycling machine which is equipped to recycle the plastic waste received in it. [5] Method according to one of the preceding claims, characterized bythat a label is printed on at least one of the processing machines using a printer to identify the plastic waste placed in the respective receiving containers. [6] Method according to one of the preceding claims, characterized by that pre-printed labels are provided on at least one of the processing machines to identify the plastic waste placed in the respective receiving containers. [7] Disposal system for plastic waste arising from processing machines, in particular for carrying out the method according to one of the preceding claims, with a plurality of receiving containers for the plastic waste, with a marking device on each processing machine for marking plastic waste received in the receiving containers, with transport means for transporting the receiving containers and with a recycling device for processing the plastic waste transported by means of the receiving containers. [8] Disposal system according to claim 7, characterized by that the recycling facility has several recycling machines which are equipped for the recycling of different plastic waste. [9] Disposal system according to claim 8, characterized by that the marking device of at least one of the processing machines has a printer.
