Photographic Waste Solution Concentrator Usage
November 2024
SHIMAUMA Print,Inc. and/LaboNetwork Co., Ltd.
The process of developing silver halide photographs in stores and labs produces waste solution. Our Group has long had all of this waste solution properly collected and disposed of as industrial waste. SHIMAUMAPrint,Inc. Kagoshima Lab and LaboNetwork Co., Ltd. Takamatsu Lab have enhanced their environmental efforts by introducing equipment to concentrate this waste solution.
At the Kagoshima Lab, the photographic waste solution concentrator has reduced the number of visits to collect waste solution, which previously amounted to 720 tonnes per year (the equivalent of 80 large tanker trucks) by roughly 90%. Likewise, while the Takamatsu Lab used to produce 461 tonnes of waste solution each year (the equivalent of 52 large tanker trucks), the concentrator has enabled it to reduce the number of collection visits by roughly 10%. Together, the efforts by these two labs have cut GHG Scope 3 emissions by over 54 t-CO2.In addition, silver halide waste solution contains rare metals. By concentrating the solution, they have also succeeded in generating new revenue exceeding the costs involved.
