Reducing Waste Emissions

The Company’s industrial waste largely consists of rubber and plastics. As rubber is difficult to reuse, the Company strives to reduce waste primarily by curbing waste generation at manufacturing sites.
As initiatives to reduce wastes related to existing products, we promote manufacturing that does not reduce efficiency even in small batch customization through production planning and process improvement, in addition to reducing loss and defective products through day-to-day improvement activities.
In fiscal 2019, although the total volume of raw material-related wastes decreased due to low production volume decrease, the intensity increased. In fiscal 2020, in addition to the activities continuing from fiscal 2019, we will promote the product development and new production methods considering the waste reduction from the designing stage. We have already achieved zero emissions* through thorough waste separation.
We will continue to work on reducing waste generation for the efficient use of resources.

*Definition of zero emissions: Final landfill disposal rate of less than 1% (final landfill disposal rate = final landfill disposal volume/volume of waste generation)

Reduce energy consumption

We aimed to reduce energy consumption by improving the productivity of existing products.
In addition, we worked on systematic energy-saving initiatives including the energy saving patrol whereby we check our production processes for their improvement activities and energy usage and give guidance to correct inefficient use and the energy saving diagnosis by external energy management experts.
In fiscal 2019, as measures to promote energy saving for equipment and buildings, we renewed transformers at Ashikaga Plant and Nankai Plant and reinforced heat insulation of steam pipes at Nankai Plant. In addition, we promoted switching to LED lighting at Ashikaga Plant, Wakayama Plant, and Head Office. However, due to a decrease in production volume, we were not able to achieve the target for energy consumption intensity. In fiscal 2020, we plan to review and commercialize ESCO business* suspended in fiscal 2019.

*ESCO business: a business model to cover all expenses incurred in connection with energy saving-related refurbishment with the savings from reduced utilities expenses.

Introducing renewable energy

The Company actively uses renewable energy. We started introducing solar power generation systems gradually in our domestic plants since fiscal 2010. Ashikaga Plant sells electricity that it generates to the Tokyo Electric Power Company Group using Japan’s feed-in tariff (“FIT”) scheme for renewable energy.

TOPICSTOPICS: Head Office declared as Kansai Eco Office

The Company declared its further engagement in environmental activities as an “environmentally-friendly office” in April 2019. “Kansai Eco Office” is an activity undertaken by Union of Kansai Governments, which registers offices engaging in environmental activities such as energy saving as an “environmentally-friendly office.”
Our efforts in fiscal 2019 included appropriate temperature setting of air conditioners, promotion of summer/winter eco-friendly fashion and electricity saving, switching to LED lighting, introduction of energy-saving/new energy equipment, promotion of green purchasing, waste recycling, and enlightenment activities for employees.
By switching mercury light at workplace of the laboratory building to LED lighting, we were able to reduce power consumption by approximately 62%. Also, LED lighting is well-received by employees as it takes a shorter time to light up than mercury light. We will continue to promote energy saving and also work to realize pleasant working environment.

TOPICSSwitch to high-efficiency equipment and LED lighting system

At Ashikaga Plant, we employed the Ministry of the Environment’s ASSET* to switch to a power generator that uses city gas instead of heavy oil and air conditioning equipment that uses waste hot water from the generator, and also introduced LED lighting. The subsidy is granted for CO2 emission control measures subject to the introduction of certified products using leading and low-carbon technology. We started to work on the concept in 2015 and it took us three years to evaluate profitability and finalize the plan to apply for the subsidy and finally complete the plan.
The new power generator provides most of the electricity used by the plant (half in the summer and two-thirds in the spring, fall and winter). In fiscal 2018, such equipment replacements and shift to LED lighting reduced CO2 emissions by 1,606.9t-CO2, or over 19.5% of the annual CO2 emissions at Ashikaga Plant.

Improvement of Energy management technology

We have energy management training for energy managers to learn about equipment and design energy saving equipment for manufacturing.
