Effective Use of Resources and Waste Reduction

We are advancing waste reduction activities in various workplaces from plants through offices and employee dining halls. Together with reducing waste, we are also aiming to achieve a recycling rate of at least 99.5% in Japan as we aim toward the realization of a circulating society.

Promoting Waste Reduction Activities

To contribute to the realization of a circulating society, the CITIZEN Group is advancing zero waste activities that include not only reducing waste emissions but also promoting recycling. In FY 2020, the recycling rate increased by 0.2 percentage points to 99.8% in Japan. In the future as well, we will continue striving to recycle resources through means, such as putting waste to effective use.

A case: CITIZEN MACHINERY (Vietnam)

Recycling of sand

CITIZEN MACHINERY VIETNAM manufactures cast metals to be used for machine tools. Cast metals are produced by pouring molten iron into a sand mold. To prevent the sand mold from falling apart resins are mixed with the sand, and since it is difficult to separate the resin from the sand after cast metals are removed, the sand cannot be reused and therefore has traditionally been sent to landfill.
In recent years, however, as Asian countries have tightened their environmental regulations, we can no longer dispose of this waste in the traditional manner.
In response, we are promoting an initiative to recycle the sand into construction blocks and brick material. The recycling rate of waste materials has improved significantly, with the rate sitting at 8.0% in 2016, 62.6% in 2017, 95.9% in 2018 and 95.4% in 2019, and the high recycling rate has been maintained, in 2020 we maintained the same level of performance as the previous year at 96.3%. CITIZEN MACHINERY VIETNAM will continue implementing initiatives to reduce our environmental impact.

Reducing the Volume of Water Used in Dicing

In the dicing process included in product assembly, CITIZEN ELECTRONICS has introduced a system to collect wastewater from dicing equipment and filter it for reuse, enabling a reduction of 11,950 L per hour (at full capacity) in water use to contribute to the preservation of water resources
