Products That Contribute to Reduction of Waste and Energy Savings in Marking Processes

FP-1000 Series UV Laser Coder, a product that changes common conceptions about packaging marking

No faded marking

Marking that isn’t affected by water, oil, or powder on the surface and is resistant to rubbing with alcohol

No downtime

KEYENCE’s UV laser coder eliminates downtime for replacing ink ribbons and thermal heads.

No consumables

Say goodbye to costly consumables, maintenance, and inspections.

Eliminating CO2 Emissions from Ink Ribbon Disposal

Because conventional thermal printers use ink ribbons, CO2 is emitted when disposing of used ink ribbons.
UV laser coders do not use ink ribbons, so these conventional CO2 emissions are eliminated.

Disposal loss simulation

Assume that 4 ink ribbons are replaced each day at a factory that operates for 25 days each month. The result is that 1200 ink ribbons must be disposed of each year.
If 1 ink ribbon weighs 500 grams, 1200 ink ribbons will weigh 600 kilograms, which converts to approximately 1.2 tons of CO2 emissions during the disposal of these ribbons.
UV laser coders do not use ink ribbons, so these conventional CO2 emissions are eliminated.

Management of Chemical Substances Contained in Products

More and more regulations are being applied to the chemical substances contained in electrical and electronic products around the globe.

KEYENCE promotes green procurement of components and materials that we use in our products while sharing the various standards related to chemical substances in products with our suppliers. We are also working to fully comply with the various national and regional regulations on chemical substances as represented by the RoHS Directive and REACH regulation in the EU.

Efforts to Provide Safe Products

Ensuring product safety is the premise to advocating quality improvement.
We are working to further reduce risk during product design, development and manufacturing while complying with laws and regulations on product safety.

Efforts Regarding the EU’s RoHS Directive

In order to contribute to both the health of the human race and the conservation of our global environment, we are working to eliminate heavy metals and other harmful substances from our products. We are also continuously working for compliance with the RoHS Directive, the most prominent of the regulations on chemical substances contained in products.

RoHS Directive

Electrical and electronic equipment placed on the EU market must not contain restricted substances under the RoHS Directive.

Restricted substances under the RoHS Directive

Lead, Mercury, Cadmium, Hexavalent chromium, Polybrominated biphenyls, Polybrominated diphenyl ethers, Bis(2-ethylhexyl) phthalate*1, Butyl benzyl phthalate*1, Dibutyl phthalate*1, Diisobutyl phthalate*1

  • *1 The specific phthalates which added by (EU) 2015/863. Most KEYENCE products are subject to the regulation from July 22, 2021.

Reducing Our Environmental Impact Through Business Activities

Efforts Toward Collection and Recycling

Paper recycling

We also conduct thorough collection and management of paper materials. In addition to efforts to digitize application forms that used paper in the past, we have installed recycling containers on each floor of our office. Paper is collected by a used paper company for delivery to a paper manufacturer. Through this recycling process, the paper can be reused for the production of cardboard boxes and other products.

Efforts Toward the Reduction of CO2

Switching to LED lighting

As part of our efforts to reduce our environmental impact, we are reducing our carbon footprint by switching to LED lighting at our head office building and all distribution locations. LED lighting reduces carbon dioxide emissions by approximately 64% compared to conventional lighting.

Replacing AC Equipment with High-Efficiency Equivalents

By switching to energy-saving air conditioner models with lower power consumption and compact models that use less resources, KEYENCE is employing environmentally friendly technology that will reduce its carbon footprint.

Adoption of Environmentally Friendly Vehicles

To further reduce its environmental impact, KEYENCE is gradually changing its fleet of commercial vehicles in Japan to environmentally friendly models.

Efforts Toward the Reduction of Waste at Distribution Locations

In the past, because packaging boxes were prepared for each product size, it was necessary to use cushioning material to fill the extra space. Through the use of automatic packaging equipment, we have cut down on the wasted space inside packaging. This has allowed us to reduce the amount of cushioning material that is required. It also contributes to the unification of packaging and allows us to run facilities with a smaller investment of resources and space.

Acquisition of ISO 9001/14001 Certification

KEYENCE has acquired ISO 9001/14001 certification for its efforts to contribute to the environment through business activities and products.
