であった。In addition, in recent years, medical waste treatment methods have been proposed in which medical waste is collected in a flammable container with a lid, incinerated together with the flammable container with a lid, and specific medical waste such as an injection needle or a syringe is dissolved. However, in the case of these treatment methods, there are problems in handling the residue after incineration, and it is necessary to sort and sort specific medical wastes for disposal.

処理する間に同様な問題をかかえている。As mentioned above, in the medical waste treatment methods that have been conventionally adopted, medical waste generated from hospitals and the like cannot be discarded as it is, and must be sorted and sorted one by one. It was In addition, in any of the conventional treatment methods (methods such as treatment by hospitals, etc., and methods entrusted to specialists), waste directly contacts the human body during treatment (this means that hepatitis B, AIDS, etc.) There is a risk of secondary infection). Furthermore, there is a risk that injection needles, etc., will be reused by a third party when stored after being processed by a hospital or the like, and management of storage is difficult. On the other hand, even specialists have the same problem during processing after collection from hospitals.

器ごと溶解処理することを要旨とする。In order to solve the above-mentioned problems, the medical waste treatment method of the present invention, the non-metallic combustible container with a lid is put into a batch without storing medical waste discharged from a hospital or the like, and stored. After collecting the flammable container with a lid in the storage state,
The gist of the invention is to put it in an electric furnace for steel making together with scrap, and to dissolve the combustible container with a lid containing the medical waste together with the scrap while making the steel.

料としては可燃性材で、プラスチック系、紙、塩化ビニ
ール系等の注射針等により破れないものが好ましい。Therefore, the flammable container with a lid used in the present invention is oneway
It is not a method of conventional recovery and reuse. Further, the shape and the like are not particularly limited as long as the outer shell of the combustible container with a lid is robust in order to ensure safe storage. The strongest reason for its robustness is that, when injection needles and the like are mixed in medical waste, there is a danger of breaking through the container with the needle during transportation and storage. Therefore, it is preferable that the material of the container used in the present invention is a flammable material that is not broken by a plastic needle, paper, vinyl chloride needle, or the like.
次に本発明の作用について説明する。 Next, the operation of the present invention will be described.

される。Medical waste can be collectively disposed of in a container without being sorted or discarded, and the combustible container with a lid can be collected and transported while being sealed in a robust combustible container with a lid by mechanical means such as a hawk lift or a crane. Since it can be done by any means, it does not touch the human body at all, and the risk of secondary infection such as hepatitis B and AIDS can be completely prevented. Furthermore, medical waste together with flammable containers with lids is put into a general-purpose electric furnace for steelmaking and melted in a high temperature range of at least 1400 ° C or higher and in a short time while contacting melted high temperature scrap. Therefore, non-combustible substances such as metal objects such as injection needles and drug containers and non-combustible substances such as glass such as bottles are completely melted, while other combustible substances are completely combusted. In addition, the metals contained in medical waste are recycled along with scraps and recycled as steel materials, and other non-combustible substances such as glass are discharged as slag.

れなかった。The sealed and stored container was loaded on a special vehicle by a hawk lift or the like and the container was collected. Store the collected containers strictly in a designated storage area provided indoors. The stored containers were put into a clam cell type charging bucket together with other scraps by an oak lift, and 20 containers / charge together with the lidded plastic container were charged, and ordinary melting and refining was performed in a 70T electric furnace at a high temperature of 1600 ° C or higher. The medical waste including the injected needle and the plastic container with the lid were soon completely burned or dissolved. For reference, the molten steel after tapping was sampled and analyzed, but the amount of medical waste processed was at most 0.5% of the total scrap input.
Since it was only the following, no effect on the molten steel composition was observed.
以上の如く本発明医療廃棄物処理方法の過程において

の比較をまとめた。As described above, in the process of the medical waste treatment method of the present invention, since there is no contact between the medical waste and the human body, the complete detoxification treatment can be established. Table 1 summarizes the comparison between the conventional treatment method of medical waste generated from hospitals and the like and the treatment method of the present invention.
〔発明の効果〕 本発明は、以上説明したように構成されているので、
次に記載されるような効果を奏する。 [Effects of the Invention] Since the present invention is configured as described above,
The following effects are achieved.
病院等から発生する医療廃棄物を非金属製の蓋付可燃
性容器に分類や廃棄することなく一括して投入すること

れ、該容器ごと機械的手段により回収運搬できるので、
医療廃棄物が人体と触れる過程が全くなく安全に医療廃
棄物を処理することができる。It is easy to put in medical waste generated from hospitals etc. in a non-metal combustible container with a lid without throwing it away and discarding it all at once. Since it can be collected and transported by mechanical means,
The medical waste can be safely processed without any contact with the human body.
また、医療廃棄物を収容する容器が非金属製の蓋付可
燃性容器であるため、軽量で取扱が容易である。Further, since the container for containing medical waste is a non-metal combustible container with a lid, it is lightweight and easy to handle.
また、医療廃棄物を収容した非金属製の蓋付可燃性容
器は、スクラップとともに汎用の製鋼用の電気炉に投入
され、製鋼を行いながら処理されるので、溶解工程の高
温域で、かつ溶解された高温のスクラップと接触しなが

抑えることができ、また処理による悪臭を発生すること
もない。In addition, the non-metal combustible container with a lid containing medical waste is put into a general-purpose electric furnace for steelmaking together with scrap, and is processed while steelmaking is performed. Since it is melted in a short time while coming into contact with the scraped high-temperature scrap, the processing time and the processing cost can be suppressed, and no bad smell is generated by the processing.
さらに、医療廃棄物に含まれる金属はスクラップとと
もに再生処理され鋼材としてリサイクルされるととも
に、ガラス類等の他の不燃物質はスラグとして排出され

安全かつ容易に行うことができるので、これによっても
処理コストを抑えることができる。Furthermore, the metals contained in medical waste are recycled along with scraps and recycled as steel materials, and other incombustible substances such as glass are discharged as slag, so the treatment of residues is completely different from the normal steelmaking process. Since it can be carried out safely and easily without doing so, the processing cost can be suppressed also by this.
