Waste Reduction

Waste Reduction Initiatives

The amount of waste excluding valuable resources discharged by the Sumitomo Riko Group as a whole in fiscal 2019 fell by 8.0% compared with fiscal 2017, and the total amount of waste discharged by the Group in fiscal 2019 declined by 4.7% compared with fiscal 2017. Meanwhile, emission intensities for these two categories in fiscal 2019 were down 4.1% and 0.6% respectively from fiscal 2017 levels. These results reflected reductions in defects and the improvement of yield, as well as the recycling of unvulcanized rubber (recovery of valuable resources). (The target for reduction of waste excluding valuable resources was set for fiscal 2017 onward.)

Example of waste reduction

Refillable sprayer

Refillable sprayer

For many years, the detergent used to clean molds and machinery at the Saitama Plant was of a spray can type. This meant that, once empty, these spray cans became waste, as were the cardboard boxes they were delivered in. To solve this problem, the Plant decided to abandon the use of spray cans and switch to refillable sprayers.
With this initiative, the use of spray cans was completely abolished, and the cardboard packaging was also eliminated at the same time. Because the detergent is now purchased in 18-liter drums, these drums have become a new form of waste, but overall, this initiative has resulted in a reduction in waste of 207 kg per year.

Approaches to ocean pollution

As an activity to improve the problem of ocean plastics for fiscal 2019, the cafeteria at the Komaki Plant switched from plastic dessert spoons to paper ones. Global Headquarters also abolished the sale of beverages in PET bottles in its drink vending machines, replacing them with canned beverages. We will continue to make improvements one step at a time wherever we can.

Issues to Be Addressed and Responses

Environmental Management Promotion Officers of Business Headquarters will again spearhead our waste reduction initiatives in fiscal 2020, with the aim of achieving the objective for fiscal 2022 (5% reduction in waste intensity compared with fiscal 2017). In particular, we will boost the ongoing efforts of each business unit in the reduction of defects and improvement of yields, to reduce waste emissions and reuse generated waste by converting it into valuable resources for recycling.
Environmental Management Promotion Officers of Business Headquarters will take the lead in applying best practices with significant defect reduction and yield improvement impacts to relevant sites with the aim of stepping up waste reduction initiatives throughout the Group.
