Waste Reduction Efforts

We aim to reduce, reuse, recycle, or recover as much waste as possible. Our group's waste management is based on proper sorting, and safe disposal. All of our business sites respect the requirements of the Environmental Action Guidelines and local regulations.

Waste Management

We strive to not only recycle waste, but also to curb the amount of waste itself. Emissions in 2019 totaled 12,627 tons, resulting in a continued annual reduction in emissions. In addition, we regularly visit industrial waste disposal contractors to confirm that the contracted industrial waste is properly processed.

Equipment that uses polychlorinated biphenyl (PCB) is strictly stored, controlled, and notified based on laws and regulations. The treatment of waste containing high concentrations of PCBs is commissioned to the Japan Environmental Storage and Safety Corporation (JESCO), and the treatment of waste containing low concentrations of PCBs is commissioned to facilities certified for detoxification treatment. Plans are made to ensure that all waste treatment is completed safely and reliably by the deadlines specified in the national basic plan.


Preventing Soil Pollution

When harmful chemicals are passed into and accumulated in the soil, there are concerns about their negative impact on human health, crops, and ecosystems. In an effort to prevent harmful chemical substances being passed into the soil, we systematically implement measures to reduce the risk of chemical leakage and to prevent permeation into the soil in the unlikely event of leaks.
Furthermore, in our annual environmental audits, we confirm the management status of chemical substances, including the storage locations of chemical substances and the management status of facilities used, and the status of response procedures in the event of leaks, and actively propose measures to further reduce risks.


Facilities that have already taken measures

  • Construction work to prevent leakage from waste liquid collection equipment (Kawajiri Factory and Saijo Factory)
  • Construction work to prevent chemical leaks (Saijo Factory)
  • Construction work to prevent underground permeation (Naka Factory, Musashi Office), etc.

Contributing to SDGs

Renesas’ efforts in Waste Reduction contributes to these Sustainable Development Goals targets:

3.9 By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination.

11.6 By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management

12.4 By 2020, achieve the environmentally- sound management of chemicals and all wastes throughout their life cycle, in accordance with agreed international frameworks, and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment

12.5 By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse

15.3 By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world

15.4 By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development
