Environmental Initiatives
Reducing Environmental Impact
from Various Manufacturing Aspects
What we emphasize is not just 'choosing environmentally friendly methods,'
but optimizing on-site operations and processes themselves.
We continue to make improvements in daily production activities,
including reducing wasteful energy consumption, reducing loss and defects, and improving exhaust and work environments.
Production System
By organizing daily production operations including planning, quality, maintenance, and improvement, we reduce energy consumption and material loss, leading to environmental impact reduction.
Reduce unnecessary rework through loss and defect reduction
We implement daily standardization of manufacturing procedures and inline quality checks.
Optimize operations through energy visualization
We thoroughly manage operation/stop conditions for each line and review daily production plans.
Improve work environment for stable production
Achieve stable production through systematization that reduces work burden. Environmental impact is also reduced by minimizing rework.
Equipment Introduction
We are advancing equipment introduction and renewal that leads to environmental impact reduction while improving production efficiency and quality stability.
Equipment contributing to energy saving and efficiency
High-efficiency drying/heating equipment, printing machines with high-efficiency motors, LED lighting, etc.
Equipment leading to process stabilization = loss reduction
Automatic weighing/mixing systems, inline inspection machines, etc.
Consideration for exhaust and work environment
Exhaust efficiency/treatment equipment, local exhaust/ventilation design, etc.
Solvent-Free Coating
Solvent-based coating tends to require solvent evaporation processes, with VOC emissions and drying/ventilation energy load becoming issues.
Solvent-free coating changes that premise and is a method that easily leads to environmental impact reduction from the process origin.
Solvent-Based Coating
Environmental Impact Points
- Solvent evaporation tends to require exhaust and odor countermeasures
- Drying ovens and ventilation are prerequisites, making heat source, blowing, and exhaust energy-intensive
- If drying conditions are difficult to optimize, process load may increase
Solvent-Free Coating
Points That Can Be Reduced
- Structurally easier to suppress solvent-derived VOC emissions
- Tends to lead to elimination/shortening of drying process, aiming for energy load (=CO₂) reduction
- Reduces countermeasure burden for odor and work environment, making on-site handling easier to improve
Process Differences
Solvent-Based Coating
(Exhaust)
Solvent-Free Coating
* Applicability and reduction range vary with resin type, curing method, and substrate conditions. We select the optimal method according to application.
Non-Solvent Lamination
Dry lamination tends to include solvent removal through drying, with VOC and drying energy tending to be the focus of environmental impact.
Non-solvent lamination allows for design that reduces overall process load on the premise of not using solvents.
Dry Lamination
(Solvent Type)
Environmental Impact Points
- Drying ovens and exhaust for solvent evaporation tend to be necessary
- Equipment and operational load tend to increase including odor and exhaust treatment measures
- Energy consumption tends to increase depending on drying and production conditions
Non-Solvent Lamination
(Solvent-Free)
Points That Can Be Reduced
- Easier to suppress solvent-derived VOC emissions
- Drying process tends to be unnecessary/shortened, making it easier to reduce heat source, blowing, and exhaust energy load
- Easier to address concerns about residual solvent and reduce risk of impact on contents
The Key Point is 'Presence of Drying Process'
Because non-solvent lamination has a structure that doesn't use solvents, the evaporation process through drying ovens is unnecessary or significantly shortened.
This reduces the load required for heat source energy and exhaust treatment, making it easier to contribute to CO₂ emission reduction as a result.
* For non-solvent, material/substrate compatibility and condition setting affect quality. We design optimal conditions according to application and required performance.
