Measures for Recycling and Conserving Resources

Measures taken at offices

Promoting waste minimization and recycling

Through measures such as use of iPads and better printer settings (double-sided printing and printing two pages per each side of paper), we are able to reduce our use of office paper. We also separate office waste into 12 different types and try to recycle it into resources whenever possible.

Promoting green procurement

We employ a system for office purchases whereby priority is given to purchasing products that comply with the Act on Promoting Green Purchasing or are EcoMark-certified. We summarize the amount of expenses for purchasing goods and the ratio of green purchases each month and distribute the results widely throughout the company in order to further increase consciousness about reducing costs and green procurement.

Promoting PET Bottle Cap Recycling Campaign

Since 1st of September 2015, our office started to collect PET bottle caps which are disposed of as plastic garbage every day. The purpose of this activity is reducing CO2 emissions from the incineration of PET bottle caps; also the proceeds obtained by sale of PET bottle caps go to a charity such as UNICEF.

Results of this activity in the past are as follows:

  Number of collected caps (pcs) Weight of collected caps (kgs) Number of vaccinations
(If converting all sale into vaccinations.)
Quantity of CO2 reduction (kgs)
2015 9,890 23.0 12 72.5
49,020 114 60 359.2
As of  July 2017
27,950 65 33 204.8
As of  July 2017
86,860 202 105 636.5

Measures taken at sea

Reducing risks to water

Most of the water used for daily living on ships is seawater that has been puri­ed using 80°C jacket cooling water that was used to cool the engine during a voyage. The interior of the freshwater generator is maintained as a vacuum to lower the boiling point of the water so that seawater fed to the device is vaporized by the heat of the jacket cooling water. It is then condensed by the condenser to make distilled water that is used for various purposes on board.

Ship dismantling and recycling with Health, Safety and Environment considerations, recycling of resources

Iron and various other types of metals are used in ships. The metals collected after dismantling a ship are valuable resources and can be recycled into new products and used for new services to support the growth of local lives and employment. In the ship dismantling and recycling stage, the “K” Line Group conducts responsible dismantling and recycling of resources. When we dismantle ship, inspect ship recycling yards and use our unique “K” Line checklist to carry out environmental impact assessment to check that the work is being carried out safely, that substances that affect the human body or the environment are being properly collected, that the dismantling process does not have an impact on the surrounding environment, and other points.
A pilot model project to build so-called “advanced country-model” ship recycling system (the Muroran Project) was launched under the initiative of Japan’s Ministry of Land, Infrastructure, Transport and Tourism. This ship recycling system is safe, efficient and eco-friendly and can be materialized by taking advantage of skills and techniques in advanced countries. In 2010, “K” Line joined the project and conducted a demonstration ship dismantling and recycling experiment on its New York Highway. Based on the knowledge yielded by this project and on numerous past experiences in ship dismantling, we are also putting efforts into projects that follow the ship recycling convention adopted by the International Maritime Organization (IMO) in 2009 ahead of it coming into effect.

Ship demolition with safety and environmental considerations
Ships that have completed all their missions are demolished and utilized effectively as iron resources. Most demolition work, however, is done manually because it is hard to mechanize or automate. Consequently, occupational health and safety and environmental burden need to be considered in ship demolish work. It is also important to recognize in advance which parts of the ship contain substances harmful to the human body and/or the environment.
Inventory of the car carrier New York Highway
Built in 1985, this ship used asbestos, TBT, and CFC (specified chlorofluorocarbon), substances that are now banned. Asbestos was used for gaskets tucked into connections of portions that become hot, including the engine's exhaust system, boiler furnace, and steam piping. TBT, which at the time was not banned, was used for the paint for the ship bottom. TBT paint is permitted to be sealed off by coating the painted surface with another paint not containing TBT. CFC was used for the freezer for cooling down the large amount of CO2 serving as fire extinguisher for the cargo hold, where cars are loaded. An inventory is a document that includes drawings and a detailed list of portions where these substances are used, along with the amount of each substance. Information contained in the inventory can be referred to for collecting the harmful substances safely without letting them disperse, which prevents impact on the surrounding area.
Taking part in the Muroran Project
A pilot project for establishing a safe, efficient, advanced ship recycling system was launched under the initiative of Japan's Ministry of Land, Infrastructure, Transport and Tourism. This project involved a demonstration ship demolition experiment, which was undertaken in Muroran, Hokkaido, from February- October 2010. The ship used in this experiment was the New York Highway, a car carrier formerly operated by "K" Line. The experiment results yielded a great deal of knowledge needed for demolition. As much as 13,732 tons of iron was also collected as a resource.
