Waste and Recycling

To achieve zero emissions of waste (an industrial waste recycling ratio of 99 percent or more), the Chugai Group aims to increase its recycling ratio and further reduce its amount of landfill waste.

Waste Reduction

Industrial Waste in 2017

In 2017, the amount of industrial waste generated was 2,854 tons, a 12 percent increase compared with 2016. The primary factor in this increase was an increase in waste oils, waste acids and waste alkalis totaling 221 tons, associated with an increase in production.
The recycling ratio was 76.4 percent, a decrease of 1.8 percentage points from 2016. The primary factor in this drop was an increase non-recyclable waste associated with an increase in production.
The final disposal ratio fell by 0.2 percentage points from 2016, to 0.8 percent. Since 2014, we have maintained a ratio below 2 percent.
We have also progressed toward our goal of achieving zero emissions at three or more facilities, with three facilities reaching a recycling rate of 98 percent or greater.

Proper Disposal of Waste Materials

Twice a year, Chugai holds conferences for persons in charge of waste, mainly those at plants and research laboratories.
These conferences help avoid illegal disposal, and reduce waste risk by informing those concerned of revisions in waste disposal laws and regulations and by providing proper disposal information. In terms of waste disposal methods, we are required to make an effort to conduct on-site verification of waste disposal contractor facilities. Our goal for 2017 was an on-site verification rate of 40 percent or more (100 percent or more in three years). In 2017, we achieved that target, conducting on-site verification of 43 percent of our waste disposal contractors.

Reduction in PPC Paper Used

Purchases of plain copier paper were reduced by 22.9 percent from 2016 by ensuring efforts to control the volume of materials distributed at meetings and to use multi-page and two-sided printing. This effort to curb distribution of meeting materials and to ensure thorough control over copier use were factors in this decrease. We also continue to promote purchasing of paper that complies with Japan’s Green Purchasing Law.
