〔The Environment〕For the Global EnvironmentEfforts in manufacturing

KOSÉ makes continuous efforts to care for the global environment in various aspects of its production activities, including the implementation of measures to reduce industrial waste and energy consumption to mitigate global warming and prevent environmental pollution.

Environmental Management in Production

KOSÉ’s Production department is mindful of its effects on the environment. In 2000, the Gunma factory has obtained an ISO1400 certification, followed by the Sayama factory and other affiliated factory in 2002 and 2003 respectively. Transfer to the revised ISO1400, enacted on September 2015, is currently in progress. Both the Business Management and Production departments are pushing for further improvement toward the conservation of energy.

Promotion of recycling

Promoting Waste Recycling

KOSÉ’s manufacturing sites place emphasis on recycling with the aim of using recycled materials for the benefit of society, rather than simply disposing of generated waste. The greatest efforts are focused on material recycling, combined with chemical and thermal recycling, to minimize landfill waste and simple disposal. Based on this basic policy, each worksite is required to sort out waste into recyclable or non-recyclable prior to collection to improve the recycling rate and reduce industrial waste. We regularly review recycling companies and visit waste treatment firms for on-site inspection to ensure proper waste treatment.

Material recycling:Materials are recycled back to their original forms. (e.g., from plastic to plastic, from paper to paper)
Chemical recycling:Materials are recycled and chemically changed into something different from their original forms for use.
Thermal recycling:Materials are recycled to be used for heat generation.

Efforts Toward Reducing Environmental Footprint


In 2011, we have implemented a cogeneration system in the Gunma factory to improve the energy consumption efficiency. We are mitigating the impact on the environment by internally generating power with natural gas as well as utilizing the waste heat from the generator to product manufacturing. Further, since the peak consumption of electricity in the factory comes from the air conditioning during summer, we are suppressing the rise of room temperature by implementing a sprinkler on the roof, coating the roof with heat-reflecting paint, and covering the windows by light shielding net.

New Production Facility in Gunma Factory Now Operational

New production facility

Last spring, in 2017, a new production facility of 18,666m² in Gunma factory started operation. In order to support the growth of production volume as the sales increases, promote more efficient production of a wide variety of products in small quantities to address diverse customer requirements, and address the aging Sayama production facility, we reevaluated and restructured our production structure and positioned Gunma factory as the “Mother” factory for all our production facilities both inside and outside Japan. In addition, through the efficient use of equipment, we aim to reduce our environmental footprint and expect to decrease the total CO2 emission in the production sector for the entire country by 20%.
