Greetings from President Konosuke Ose

High pressure gas cylinders are regarded as the lifeline of companies in the industrial gas business. They play a crucial role in the production, storage, transport and usage of industrial gases.

High pressure gas steel cylinders, which are the main cylinder type in use, eventually come to the end of their life, and are no longer suitable for filling. At times, due to various circumstances, they are then abandoned in public places, whereby people are at a loss as to how to dispose of them, being cylinders of unknown ownership and content. With pretreatment prior to final disposal of the cylinders, the need arises to discard in a safe manner any remaining dangerous gases as well as the solid mass of the dissolved acetylene cylinders. A suitable system for disposal has been required for quite some time, especially from the point of view of protection of the environment and safety in both the public and private sectors.

The Japan Industrial and Medical Gases Association, in line with the social responsibility of the industrial gas industry, established a project team, in which numerous member companies of the organization participated, for the purpose of establishing a facility to implement pretreatment for recycling or intensive scrapping of high pressure gas cylinders. The results of the project team’s investigations led to the recent establishment of CRC Western Japan Corp., which is now in operation.

CRC Western Japan is positioned as a cost center for the entire industry to undertake the scrapping of high pressure cylinders and the safe pretreatment of cylinders to be recycled. CRC Western Japan carries out professional and thorough analyses of cylinder contents, treatment of hazardous materials, and safe disposal of the dissolved acetylene cylinders, regular gas cylinders, and specialty gas cylinders submitted to it. Accordingly, it also engages in the research and development of technology for the reuse of cylinders and makes available the information acquired.

In addition to cylinders from the member companies of the Japan Industrial and Medical Gases Association, we would also like to obtain on a large scale the high pressure gas cylinders designated for disposal and owned by members of the Japan Welding Equipment Society and the High Pressure Gas Cylinder Management Committee, as well as from companies engaged in the use of high pressure gas cylinders. We sincerely hope that we can be of use in securing the safety of the work place and of regional companies, as well as in the protection of the environment.
