Sustainability - Product Initiatives (Promote Environmentally Conscious Design)
The Meiden Group is promoting development of environmentally conscious products that reduce our impact on the environment.
Any time we develop a new product, we evaluate it for energy and resource conservation, recyclability, environmental safety, and more, based on our Product Environmental Assessment Standard. If a product meets those standards, we certify it as a Meidensha Green Product.
To create products that are even more environmentally conscious and contribute to the decarbonization of society, we have also introduced and begun operating a system of “super green products,” which are even better than green products.
For the evaluation item “consideration of lifecycle,” we calculate CO2 emissions according to a life cycle assessment (LCA), and we encourage environmentally conscious design in order to reduce CO2 emissions.
The Meiden Group conducts an assessment of the environmental impact of a product throughout its life cycle, from procurement of components through to disposal, in accordance with our Guidelines for Environmental Action. We use the LCA method to quantify the environmental impact of products and services, which helps us to improve environmental performance at the design and development stage and to conduct product explanations to customers and PR, etc.
| [Product] Smart Maintenance System for Railway Operators (a product using an IoT controller) | |
|---|---|
| Product overview | In response to the shortage of new engineers due to the declining birthrate and aging population, railway operators are increasingly practicing CBM (Condition Based Maintenance) and labor-saving patrols and inspections. The purpose is to perform facility maintenance as efficiently as possible. To meet this need, we have developed a maintenance system that collects and stores information from sensors and meters attached to power receiving and transforming facilities and transmits it to higher-level equipment. This solution uses our IoT controller, which consumes less power than conventional products. |

| [Product] Drive Robot | |
|---|---|
| Product overview | An autonomous driving system for finished vehicles on a chassis dynamometer. An electric actuator operates the accelerator, clutch, transmission, brakes, and ignition key in the same way a human driver would. The main body of the drive robot has a single-body construction that is now made of carbon fiber reinforced plastic (CFRP) instead of the conventional metal. |
