Waste Reduction

コンテンツ

It is said that landfill sites in Japan will reach their full capacity in around 20.5 years (as of the end of FY2016). There is a risk that regulations regarding landfill disposal volume will be tightened in the future, and as a result, the upper limit of the volume will be reached or landfill will no longer be possible. If we were to make effective use of all landfill waste from our domestic consolidated subsidiaries by applying advanced processing, the processing cost of around 1.5 billion yen or more might be generated. We are reducing the landfill disposal volume of waste, by both reducing the volume of waste that we generate and making effective use of waste that has been generated, in our efforts to mitigate or avoid the above risk and help increase the number of years remaining before landfill sites reach their full capacity.

Examples of specific measures include the reuse of pulp residue generated in the manufacturing process (as a material of paper for use within our business sites) and the effective utilization of incinerated ash that is generated from fuel combustion (as a material of soil improvement agent, cement, roadbed material, or other).

The Oji Group has set FY2020 targets. In Japan, the effective utilization ratio has been increasing steadily toward the target, while the ratio in overseas countries has declined.


Effective Utilization Ratio: Targets and Results

*The FY2017 value declined from the previous year because the landfill disposal volume increased as a result of a decline in waste treatment efficiency at an effective utilization site in New Zealand.
