Description

Method and system for recycling recyclable scrapped materials

The present invention relates to a method and system for recycling renewable waste resources, and more particularly, to a method and system for dry recovery of renewable waste resources such as waste cellulose (waste paper), waste vinyl, and waste plastic. .

Behind abundant material civilization, such as mass production and industrial consumption and mass consumption, the consumption of disposable products increases, mountainous wastes are being discharged exponentially.

In particular, due to the rapid development of the petrochemical industry, hazardous industrial wastes such as waste plastic, waste vinyl, waste PVC, waste cellulose (waste) are rapidly increasing, threatening human survival.

Whether such harmful hazardous wastes can be properly disposed of environmentally is a challenge for all humanity. In the case of waste such as waste PVC, waste plastic, waste vinyl, and waste cellulose, environmental pollution and harmful effects on the human body, and in the reality that petroleum resources are exhausted and the price is soaring, it is a valuable resource. Due to its own disposal difficulties, it is emerging as a key task in solving the waste problem.

In particular, the amount of plastics and vinyl used is increasing rapidly in plastic bottles and garbage (PE) in plastic bottles, garbage bags, and various kinds of packaging products for daily use. It is rapidly increasing, and the amount of use is increasing in various containers and packaging for business. Simple waste and illegal disposal of waste plastics, vinyl and waste PVC wastes acts as an environmental pollution source that increases air pollution, soil pollution, and overall environmental pollution load.

In particular, air pollution acts as a source of dioxins, harmful gases, and odors due to the incineration of waste PVC waste plastics and waste plastics.In particular, air pollutants, which are specific wastes, have low performance not to be incinerated or disposed of. Increasing the amount of dioxins hidden in the atmosphere, such as illegal incineration, is also a serious source of soil pollution by embedding soil in soils and reducing the porosity of soils and preventing microbial traffic. Especially in rural areas, the amount of garbage left in the soil is high, and the source of healthy food production is fundamentally polluted, which poses a fundamental problem that threatens human life. In addition, the bulky but low weight consumes a lot of expenses in collecting and transporting, avoiding collection from private collectors, which makes it impossible to use resources as resources. In particular, in the regeneration of resources, the value added is gradually losing its value as a resource. The amount of plastics is increasing due to the waste-based waste disposal system, and the pollution of landfill sites is further increased by simply placing landfills in plastic bags. In addition, although renewable wastes were collected separately by the policy of waste collection, they tend to become simple waste due to collection avoidance and inefficiency.

As a result, there is a problem in that the plastic waste, which is difficult to separate collection. Waste plastics such as waste plastics, waste plastics, and waste PVCs are discharged as described above. However, most of them are left to be dumped and illegally dumped. Actually, the amount of recycled waste resources such as waste plastics and waste plastics is very small compared to the amount of discharges. Therefore, enormous hazardous wastes are not recycled and are illegally discarded to contaminate soil and air. Moreover, this problem has long since become a practice and has been left unattended by anyone. Currently, waste resources are collected and collected at home and business units through the waste-based system, but in the case of plastics, waste materials collected and recycled are being mixed with general waste again. Current waste management has not been properly managed, and as a result, problems causing pollution such as massive landfilling and incineration continue to arise.

As a general problem, the separate sorting work for recycling purposes must be preceded, so the cost burden for resource recycling is too high, and huge manpower is put into the collection process, and due to excessive labor costs, the profitability of recycling is not met. Due to the limitation of the disposal capacity of wastes such as plastic and waste vinyl, the amount of accumulation is increasing, and the current operation factories are also pointed out that not only the processing capacity is insignificant but also enormous cost factors are caused by the treatment.

To this end, in the prior art, Korean Patent Publication 94-25731, 95-13678, 95-17140, 96-40605, 97-33827, 97-70338, Korean Utility Publication 95-16896, 97-16535, 97-53709, etc. Although recycling technologies of waste vinyl and waste cellulose have been disclosed, they are merely a technique of pulverizing waste paper, waste vinyl, waste plastic, etc., and melting them in a desired state to recycle them as resources. Separation, sorting, crushing and washing according to the kinds of phases, and the technology applied in a state supported by a lot of energy in these processes, it was not able to solve the above-mentioned conventional problems smoothly.

In general, in order to recycle waste plastic and waste vinyl waste, a plan that can be economically and efficiently disposed of has to be presented. For the recycling of plastic waste, processes such as separation, sorting and crushing are problematic. In the distribution process of plastic manufacturing, processing, consumption, and the like, paper, textiles, metals, soil, etc. are mixed, which makes it difficult to process. In particular, in Korea, many waste plastic wastes that are not discharged from foreign countries are dealing with difficulties. Thus, depending on the type and type of plastic waste, it should be recycled in a direction that does not require the process of fractionation and crushing.

Therefore, it is urgent to find resources for recycling through the proper treatment of waste plastics and vinyl waste, which are the main causes of air pollution and soil pollution.

Accordingly, the applicant has already filed a patent application (10-1999-14749) with the Republic of Korea on April 24, 1999, and received a patent registration (10-0316152) on November 16, 2001. Hereinafter, the features and problems will be described.
