Reduce Waste Volume (Output Level)

Effort Status

  • As a medium term goal for our environmental policy, we are working on "waste volume (output level) reduction". In particular, for sintering waste our goal is "reduction of 30% against FY2013 levels by 2030", and we are striving toward this at all business locations.
  • Our results are as per the graph below, and although there are fluctuation factors, on an output level basis the reductions are progressing on track.
    In FY2020 the COVID-19 impact has reduced production volume the output level result has worsened against the prior year.

Specific examples

Example 1 Internal leveraging of waste acid/waste alkali

Waste acid/waste alkali from manufacturing processes are re-used as counteragents in our internal drain water treatment plant, reducing the volume of work undertaken by our outside partner.

Example 2 Paperless/paper usage reduction initiative

The whole company is engaged in promoting a shift to paperless via the introduction of an electronic notice circulation system, and reduction in usage of copy paper.

Example 3 Adherence to trash control

Trash segregation is displayed in various places internally. This clarifies waste for incineration by local authority, contractor waste and external recycling, which promotes recycling and reduction in trash to be incinerated.

Example 4 Melting/re-use of jigs and tools

As part of our re-use initiatives for jigs and tools, when they are no longer repairable/re-usable, they are not thrown away, they are melted and re-used as material.
