Abstract

A confidential document recycling method includes front-end processing and back-end processing. The back-end processing is performed after the front-end processing is completed. The front-end processing includes a water storage step and a soaking step. The back-end processing includes a direct recycling process and an indirect recycling process. The direct recycling process includes a barrel replacement recycling and a direct recycling and transportation step. The indirect recycling process includes drainage, shredding, dehydration, and indirect recycling and transportation steps. Through the above operation, the handwriting of the confidential document has been blurred during the front-end processing, affecting the reading, and the confidential document will be broken due to the picking action and cannot be pieced together and restored. During indirect recycling, the collection barrel in an empty barrel state is exchanged for the collection barrel that has been loaded with adsorbed water for confidential documents, which is very convenient to use. During indirect recycling, the difficulty of identification and restoration is increased by shredding the confidential documents and shaping dehydrated pulp bricks.

Description

Confidential Document Recovery Methods

The present invention relates to a method for recovering confidential documents.

In an office, each employee has different job responsibilities, so the paper documents printed and photocopied are different. For example, there are a large number of customer information, product design drawings, delivery orders, quotations, invoices, contracts, signatures, personnel lists, etc., so a large number of them need to be printed and photocopied for preservation. Although governments and environmental protection groups around the world advocate and promote office digitization (paperless), there are still many companies and administrative units that need to use paper documents to keep records. After use, they even need to be sealed for a specific number of years and cannot be recycled immediately. Therefore, special paper documents are necessary and important to preserve.

Currently, most used paper documents are handled by recycling companies, which is not a big problem for general documents. However, confidential documents or documents containing personal information are usually shredded or burned in batches to prevent them from being used by people with ulterior motives to harm personal privacy or impact the interests of companies or the confidentiality of administrative agencies.

If a company purchases a shredder to destroy confidential documents, it will be very time-consuming and take up unnecessary space if the number of paper documents is large. The purchase, maintenance, electricity and human resources of the shredder are also considerable expenses. The traditional incineration of documents is costly, there is no appropriate monitoring mechanism, and the incineration process causes air pollution and energy consumption. The waste after incineration cannot be recycled.

When the contractor conducts water marketing, the paper documents are recycled to the paper mill, thrown into the pulp machine, shredded and decomposed with water, so as to obtain recycled pulp and then make it into recycled paper. However, the biggest concern of water marketing is that the period from the contractor transporting the documents to the paper mill to the pulp machine requires the coordination of the monitoring system and related manpower, which is also the trouble of water marketing. If there is any negligence in the process, there is still a risk of accidentally leaking secrets.

The present invention is a confidential document recycling method, including front-end processing and back-end processing, and the back-end processing is performed after the front-end processing is completed, wherein: The front-end processing includes a water storage step and a soaking step; In the water storage step, water is injected into the collection barrel; In the soaking step, the confidential document is placed in the collection barrel and soaked in water; The back-end processing includes a direct recycling process and an indirect recycling process; The direct recycling process includes a barrel replacement recycling step and a direct recycling and transportation step; In the barrel replacement recycling step, the recycling operator exchanges the collection barrel soaked with confidential documents with an empty collection barrel; In the direct recycling and transportation step, the collection barrel loaded with confidential documents soaked in water is delivered to the paper mill; The indirect recycling process includes a drainage step, a shredding step, a dehydration step, and an indirect recycling and transportation step; Draining step, draining the internal water from the collection barrel; Shredding step, shredding the soaked confidential documents; Dehydration step, removing the water content of the aforementioned shredded confidential documents and making them into block-shaped dehydrated pulp bricks; Indirect recycling and transportation step, delivering the block-shaped dehydrated pulp bricks to the paper mill.

The confidential document recycling method of the present invention, through the above-mentioned treatment, process and operation, in the previous stage of treatment, the confidential documents have already absorbed saturated water content, and the handwriting on the confidential documents has been blurred and affected reading. Even if a person with intentions picks up the confidential documents from the collection bucket, the confidential documents will be broken due to the picking and picking action and cannot be easily pieced together to restore. When directly recycling, the collection bucket in an empty barrel state is exchanged for the collection bucket that has been loaded with absorbed water. This exchange concept is also very convenient for users. When indirectly recycling, the difficulty of identification and restoration is increased by shredding the confidential documents and shaping them into dehydrated pulp bricks, and the block-shaped dehydrated pulp bricks are conducive to stacking, storage and transportation.

Please refer to the first and second figures, which disclose a confidential document recycling method, including front-end processing and back-end processing, and the back-end processing is performed after the front-end processing is completed, wherein: The front-end processing includes a water storage step S01 and a soaking step S02; In the water storage step S01, the collection barrel 100 is injected with water; In the soaking step S02, the confidential document 200 is placed in the collection barrel 100 and soaked in water; The back-end processing includes a direct recycling process and an indirect recycling process; The direct recycling process includes a barrel replacement recycling step S03 and a direct recycling and transportation step S04; In the barrel replacement recycling step S03, the recycling operator exchanges the collection barrel 100 in which the confidential document 200 has been soaked with an empty collection barrel 100; Direct recovery and transportation step S04, delivering the collection barrel 100 loaded with the confidential documents 200 soaked in water to the paper mill; Indirect recovery process, including drainage step S05, shredding step S06, dehydration step S07, indirect recovery and transportation step S08; Drainage step S05, draining the internal water from the collection barrel 100; Shredding step S06, shredding the soaked confidential documents 200; Dehydration step S07, removing the water content of the aforementioned shredded confidential documents 200, and making them into block-shaped dehydrated pulp bricks; Indirect recovery and transportation step S08, delivering the block-shaped dehydrated pulp bricks to the paper mill.

The confidential document recycling method of the present invention, through the above-mentioned treatment, process and operation, in the previous stage of treatment, the confidential document 200 has already absorbed the saturated water content and softened, and the handwriting on the confidential document 200 has been blurred and affected the reading. Even if a person with intentions picks up the confidential document 200 from the collection bucket 100, the confidential document 200 will be broken due to the picking and picking action and cannot be easily pieced together to restore. When directly recycling, the collection bucket 100 in an empty barrel state is exchanged for the collection bucket 100 that has been loaded with the absorbed water confidential document 200. This exchange concept is also very convenient for the user, as shown in the fifth figure. Indirect recycling increases the difficulty of identification and restoration by shredding confidential documents 200 and shaping dehydrated pulp bricks, and the block-shaped dehydrated pulp bricks are convenient for stacking, storage and transportation.

Further detailed description of the technical features of each step.

The above-mentioned collection barrel 100 is an opaque plastic barrel, and the upper opening of the collection barrel 100 is movably covered by a barrel cover 110. In addition to preventing other debris from accidentally falling, it also makes it difficult for interested people to detect the contents, as shown in the third and fourth figures. An external water source can be provided from the upper opening of the collection barrel 100 to be injected into the collection barrel 100 and stored, and a water outlet switch 120 can be provided near the bottom of the collection barrel 100. The water outlet switch 120 can provide the collection barrel 100 with the stored water discharged from the inside to the outside. The water referred to above can be tap water or tap water mixed with dyes.

As shown in the third and fourth figures, in the water storage step S01, the collection bucket 100 is filled with water exceeding half of its capacity. The soaking step S02 lasts for at least four hours, and the confidential document 200 is soaked in the collection bucket 100 for at least four hours. Since the fibers of the confidential document 200 absorb water during the soaking step S02 and soften it, a certain amount of water and time are required, so the amount of water injected is preferably more than half of the capacity of the collection bucket 100, and the confidential document 200 placed in the collection bucket for soaking () is limited to no more than half of its capacity.

The above-mentioned direct recycling process is applicable to the confidential document 200 printed by inkjet printing. Since inkjet printing is to spray tiny ink droplets on the document to make it adhere to the fibers, when the confidential document 200 printed by inkjet is immersed in water, the ink originally attached to the paper fibers will quickly spread outward due to the effect of water.

The aforementioned indirect recycling process is applicable to laser-printed confidential documents 200. Since the laser-printed confidential documents 200 are adhered to the surface of the paper by electrostatic discharge, laser, etc. and then heated and melted, the confidential documents 200 are not easy to be blurred when immersed in water. Therefore, further processing such as shredding and dehydration is required to prevent data leakage during the above process.

The aforementioned drainage step S05 is to use an extraction device to pump water out of the collection barrel 100; or pour out the water in the collection barrel 100. In this embodiment, the water in the collection barrel 100 can flow out by turning on the water outlet switch 120, which is arranged near the bottom of the collection barrel 100, as shown in FIG. 6.

The aforementioned shredding step S06 is to insert the tool 300 into the collection bucket 100 to directly shred the confidential document 200; or to tear the confidential document 200 manually to shred it. In this embodiment, the tool 300 is inserted into the collection bucket 100 to directly shred the confidential document 200 softened by soaking in water, as shown in FIG. 7 .

The dehydration step S07 is to use a tool to reach into the collection barrel 100 to squeeze the shredded confidential documents 200 into dehydrated pulp bricks; or to manually knead the shredded confidential documents 200 into dehydrated pulp bricks. The dehydrated pulp bricks are further dried by air drying, sun drying or heating.

The front-end processing is performed when the confidential document 200 is generated or transmitted to a viewing location.
