Abstract
Medical equipments accompanies the expansion of plastics materials application, and the exhaust thing becomesvarious. The technology that safely collects the resource from various plastic is hoped for. Then, Altis Co.,Ltd is recycled
because it works as group businesses that construct the venous system for Olympus Corporation., and the medicaltreatment system waste of plastic material is sterilized and it liquefies.

Keywords: Waste plastic , infectious medical wastes , pyrolytic oil, sterilization technique

1. Introduction
The medical equipment accompanies the expansion of
the plastics material application in recent years, and theexhaust thing becomes more various. The technologythat safely collects the resource from various plastic is
hoped for.
Liquefaction by the pyrolysis introduces here is thought
to be the most effective as the method. This system wasestablished by having the sterilization technique(utilization of heat) that needed the hospital waste so far,and uniting with the pyrolytic technology by carbonization(no oxygen).
Not only cracked oil but also the generated residue andthe resource and the energy recovery from an off gas arescheduled to be advanced in the future.

2. Materials and Factory
The acceptance objects are the waste plastics, infectious
medical wastes such as PE, PP, and PS, and it isprocessed and the processing scale is processed during
10T/day in the Akita office (Be operating in 2008). It is anoperation schedule in the Nagano office on theprocessing scale in 2011 during 6T/day and in 2012
during 40T/day, and the processing plan is done ,divided
into two portions.

3. Results and Discussion
The customer of the recycling thing sells to light-sulfer
oil's (A crude petroleum corresponding) private use andoil manufacturing company, sells for the fuel heavy fuel's(C crude petroleum corresponding) power generation
and boiler, etc. , and sells for Residue RPF such as
power plant, boilers, and cement plants for the fuel as asubstitute.

6th International Symposium on Feedstock Recycling of Polymeric Materials

4. Conclusions
Our company is working on a total capitalization of thewaste plastic (city oilfield development) as achievement
and a recycling society promotion, etc. of the resource
large country that is the national policy of our country. It
is a approach as group businesses that construct thevenous system for Olympus Corporation. that
manufactures and sells apparatus for the medicaltreatment.
A plastic liquefaction recycling technology has the featureof the low carbonization and the resource reduction
compared with the recycling technique that has been
widely done so far. Recycled goods of the pyrolytic
technology that advancement, maturity, and the aspect
are waited for and the additional value is high (crackedoil) in recent years can be manufactured. Generated
cracked oil and and carbon residue decomposition
method produces the freedom of their use isadvantageous about the reservoir, which can be appliedin many industries.
Moreover, the expectation rises as environmental
measures of the enterprise that uses those products
because the negative environmental impact whengenerating it is small.
Our company doesn't limit to the medical waste, and be
working on rationalization by using with the heat use
facilities like the drying treatment etc. of the food residue
together positively.
