*1 In Kobe City, plastic-type waste of size roughly 50cm (length of one side) or below is sorted and disposed of as burnable waste in dedicated trash bags as designated by the city. For this reason, the percentage of waste converted to resources is lower than for our other sites.

CTC's Logistics Center is its only product distribution base. Devices to be delivered to clients nationwide are first delivered to the Center by our vendors. We then conduct incoming inspections and install hardware options, etc.,
before shipping out to our clients. In fiscal 2006, our recycling rate was 45%. However, it has significantly improved through the promotion of our 3Rs Movement*2.

Paper Usage

CTC is engaged in various efforts to reduce the amount of paper it uses, from advancing the digitalization of internal business forms to communicating and raising awareness of the actual amount of paper used within the company for copying and printing on a by-organization basis.

Water usage

Data centers operated by the CTC Group are using water to cool their IT equipment. Those centers are working to reduce the volume of water they use through measures such as the introduction of rainwater recycling facilities and high-efficiency heat source equipment, as well as through the practical use of district heating and cooling systems and well water.
