Received the “Health and Welfare, Biotechnology, and Medical Parts and Components Award” at the 2020 “CHO” MONODZUKURI Innovative Parts and Components Award (organized by MONODZUKURI Nippon Conference and Nikkan Kogyo Shimbun, Ltd.).
Value Proposition

Although lead, a substance subject to the European RoHS Directive, is a hazardous chemical, it is exempted from use in oxygen sensors, for which no alternative technology has been established, and is used throughout the world. At Maxell, we are committed to solving social environmental issues by focusing its management resources on lead-free oxygen sensors, which are environmentally friendly products that we sell. By developing an anode that replaces lead and a weakly acidic electrolyte that is suitable for the anode, we have commercialized a long-life galvanic cell-type lead-free* oxygen sensor that is less susceptible to CO2 and other acidic gases. By not using lead* as an anode, we are reducing the risk of soil and marine pollution and its impact on the human body.  *It means that the lead contained in each part (homogeneous substance) constituting the product is 0.1wt% or less.

Value Proposition

By reducing water leakage, mold growth, rusting of metal parts, and deterioration of wall and ceiling materials in buildings, waste is reduced. It also helps to improve the efficiency of air conditioning by filling in the gaps between housing components, such as around pipes leading to the interior and exterior of the building. In Southeast Asia, we are promoting the construction of houses using the tarpaulin method, and in North America, we are promoting the use of airtight materials.
By spreading the use of the tarpaulin method and airtight materials, we will not only improve the living space in the region, but also improve the skills of local contractors and consider the environment.

Eco-friendly package DVD-R and CD-R
Value Proposition

In recent years, responding to the plastic waste and global warming issues, there has been a growing need for environmentally friendly products and packages using fewer plastic materials.
Conventional DVD-R and CD-R products use a lot of plastic materials for the plastic case and packaging to store the disc. The NEW Packaging Design uses a paper sleeve instead of a plastic case for the package, thereby reducing amount of plastic materials used and making the product to be more environmentally friendly.
Comparing with conventional plastic cases, plastic usage has been reduced by 95% for 10-disc packs and 98% for 20-disc packs. For spindle case products that can store multiple discs in a stack are reduced by 69% for 10-disc packs and 78% for 50-disc packs. In addition, the discs stored in paper sleeves can save more space than conventional style.
* The terms of "plastic reduction" in this content refers to the amount of plastic used in new package comparing with the amount of plastic used in conventional products.

"Green Stencil Program" to support tree planting activities

Green Stencil Program

The Maxell Group's activities to combat global warming include ongoing efforts to conserve energy at plants and introduce renewable energy.
Trees absorb carbon dioxide from the atmosphere and store carbon in their bodies, making tree planting an effective means of reducing CO2 emissions.
Maxell donates a portion of the proceeds from sales of electroformed products developed and manufactured using its precision microfabrication technology to plant larch trees. The larch will contribute to a reduction of approximately 250 kilograms of CO2 over 30 years. We have named this program "Green Stencil Program" and continue to promote it.
