本発明は、病院から出る感染性医療廃棄物を利用して建
材を製造するための方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing building materials using infectious medical waste from hospitals.
［従来の技術］
病院からは、感染性医療廃棄物と言われる注射器や注射
針やその他の血のついたものがゴミとして出される。こ
の感染性医療廃棄物には病原菌が含まれているおそれが
あるので、それ自体を一般のゴミと同様に捨てることが
出来ないものである。このため、病院では感染性医療廃
棄物を他のゴミとは別の容器に溜め、病院外部の焼却処
分場まで運んで殺菌のために焼却していた。この焼却を
行なっただけでは注射針等の形状がそのまま残るので、
焼却後の感染性医療廃棄物を特別な廃棄物を捨てる管理
型処分地へ捨てなければならなかった。[Prior Art] Hospitals dispose of syringes, needles, and other blood-stained items as infectious medical waste. Since this infectious medical waste may contain pathogenic bacteria, it cannot be thrown away like general garbage. For this reason, hospitals store infectious medical waste in containers separate from other garbage and transport it to an incineration site outside the hospital where it is incinerated for sterilization. If only this incineration is performed, the shape of the needle will remain as it is, so
Infectious medical waste after incineration had to be disposed of at a special controlled waste disposal site.
［発明が解決しようとする課題〕
従来は、感染性医療廃棄物は病院外へ運んで処分するだ
けのものであり、何ら再生利用出来るものではなかった
。[Problems to be Solved by the Invention] Conventionally, infectious medical waste was simply transported outside the hospital and disposed of, and could not be recycled in any way.
また、感染性医療廃棄物の処分は、焼却前と、通常のゴ
ミを捨てる安定型処分地よりも費用の高い管理型処分地
へ捨てる費用と、運搬費とに費用がかかり、それが病院
の経営を圧迫する要因の一つになっていた。In addition, the disposal of infectious medical waste requires costs before incineration, the cost of disposing of it at a controlled disposal site, which is more expensive than a stable disposal site for regular waste, and the transportation cost, which increases the cost of transporting infectious medical waste to hospitals. This was one of the factors that put pressure on management.
この感染性医療廃棄物については再生利用の方法が考え
られていなかったので、国や地方自治体においては特別
な廃棄物を捨てる管理型処分地を年々増設したり確保し
たりする必要があるが、その増設や確保は難しいもので
あった。No recycling method had been considered for this infectious medical waste, so national and local governments need to increase or secure controlled disposal sites for special waste year after year. It was difficult to expand and secure them.
［発明の目的］
本発明は、従来から病院の感染医療廃棄物の廃棄処分に
かかっていた経費を大幅に削減し、しかも従来は廃棄処
分にしていた感染性医療廃棄物を建材の材料として利用
するようにした感染性医療廃棄物から未焼成建材を製造

〔作用］
上記構成に係る本発明によれば、注射針等の形が分から
ない程度に細か（感染性医療廃棄物を粉砕して、建材の
骨材として利用出来るような安全な形状とする。[Function] According to the present invention having the above configuration, the shape of the injection needle, etc. is crushed so finely that the shape of the infectious medical waste is not recognizable (infectious medical waste is pulverized into a safe shape that can be used as aggregate for building materials).

内を高熱高圧にし、感染性医療廃棄物の滅菌を行なう。Finely ground infectious medical waste is used as aggregate when mixing the green building material composition with aggregate and water to produce green building material. At this time, a heat generation accelerator is also mixed. The mixture is poured into a mold container to produce unfired building materials. During this process, the mold container is sealed and the inside of the mold container is heated to high temperatures and pressures to sterilize the infectious medical waste.

は出来ないものであった。Conventionally, in order to make building materials such as ceramic tiles and blocks, it has been necessary to fire the ceramic to about 1200°C.
しかし、特公平１−８９８９号や特公平ｌ−８９９０号

成物Ｙを考え出したものである。However, the inventions of Japanese Patent Publication No. 1-8989 and Japanese Patent Publication No. 1-8990 made it possible to make building materials such as ceramic tiles and blocks simply by molding them in building material molds without firing them. Composition X for unfired building materials and Composition Y for unfired building materials were devised.

染性医療廃棄物を未焼成建材用組成物の骨材に用いる。These unfired building material compositions X and unfired building material compositions Y
For 1 part by volume of aggregate, about 3 to 4 parts by volume of aggregate is mixed with about 1.5 parts by volume of water, and the mixture is poured into a suitable mold container for building materials and molded. Green building materials are produced. Taking advantage of this fact, the present invention uses pulverized infectious medical waste as an aggregate for a composition for green building materials.

混合物を冷やしていた。When aggregate and water are mixed with either composition X for green building materials or composition Y for green building materials, the temperature of the mixture rises to about 60 degrees. When pouring the mixture into a mold for building materials and shaping it, the mixture was cooled so that it would solidify quickly.

体でも良い。However, in the present invention, the temperature of the mixture of the green building material composition, crushed infectious medical waste as aggregate, and water is set to 1.
Add an exothermic accelerator to raise the temperature above 21°C. The heat generation accelerator may be any known chemical that produces an exothermic effect when mixed with cement, which is the main component of the composition for green building materials, or a known chemical that produces an exothermic effect when it reacts with water. Further, this chemical may be in liquid or powder form.
このように、未焼成建材用組成物と粉砕した感染性医療
廃棄物と水と発熱促進剤とを入れてミキサで混合する。In this manner, the unfired building material composition, pulverized infectious medical waste, water, and heat generation accelerator are added and mixed in a mixer.

らない。After thorough mixing, the mixture is placed in a mold container for building materials such as tiles and blocks, and the mold container is covered with a lid to seal the inside of the mold container. This type of container must be airtight and must be capable of maintaining the inside of the container at a temperature of 121° C. or higher, which is necessary for sterilization, for a predetermined period of time (approximately 20 minutes).

の滅菌を行なわせるものである。Inside this airtight container, the internal temperature will exceed 121°C.
This high temperature generates steam and creates a high internal internal pressure. In this way, the crushed infectious medical waste is placed in a sealed container at high temperature (121°C or higher) and under high pressure, so the autoclave method is used. (sterilization by high temperature and high pressure).In other words, infectious medical waste is sterilized during the process of pouring the mixture into a mold container for building materials and molding it into building materials.
滅菌に必要な時間経過後、蓋を開けて容器内の混合物を
冷まして取り出せば、それがタイルやブロック等の建材
製品となる。After the time required for sterilization has elapsed, the lid is opened and the mixture inside the container is cooled and taken out, which becomes building materials such as tiles and blocks.
