Increase in the percentage of resource savings

Results of FY2016

Under the Fifth Environmental Action Plan, we aimed to further increase the amount of resources saved to 1.5 times the FY2010 level. In FY2016, the total amount of resources used in Toshiba Group's major products, estimated by multiplying the amount used for products and packaging materials by the number of shipments, was approximately 280,000 tons. Based on comparisons with the previous product models and adjusting for the expected number of years of use, we also estimated to what extent resource consumption has been reduced for different products. Our comparisons show that we have reduced the use of resources by 290,000 tons, or by 144% compared to previous product models.

Future initiatives

We will continue to promote resource-saving designs for all products with the aim of further reducing resource consumption. Under the Sixth Environmental Action Plan, we aim to reduce resource consumption by a cumulative total of 460,000 tons by 2020.

Case Studies in FY2015

Case Study 1: Color MFP e-STUDIO5005AC Series

Toshiba TEC Corporation

e-STUDIO5005AC series achieved the minimum product mass and installation area*1 with 3D laser welded frame and re-design of the case layout. Also achieved the highest resource savings*1 by increasing the percentage of use of recycled plastics with the use of high post-consumer recycled material. Further achieved the highest energy savings*1 (top-level Typical Electricity Consumption*2) by using a low melting point toner and improving the thermal conductivity of the fusing belt.

Case Study 2: BiCS FLASH™*, a three-dimensional flash memory that can store massive amounts of data

Toshiba Storage & Electronic Devices Solutions Company

By arranging two-dimensional NAND flash memories in three dimensions, BiCS FLASH™ has broken through the limitation of 128-Gb die density, which was difficult to overcome due to miniaturization limitations. The memory capacity per die has increased to 256 Gb, which means a single BiCS FLASH™ die can store an amount of data equivalent to approximately 200 years' worth of newspapers. Paperless storage of information also helps conserve resources.

Case Studies in FY2014

Case Study 1: Automatic ticket gates

Toshiba Corp. Social Infrastructure Systems Company

The body width of the new EG-5200 automatic ticket gate has been reduced from 180 mm (the width of a conventional 2009 model) to 160 mm in order to increase the aisle width by 40 mm and to enable passengers to pass through gates more smoothly. We also performed a strength analysis using the finite element method (FEM) to minimize the thickness of the steel board, thereby reducing the gate's weight by 5%. In addition, we used a new material for the doors in order to minimize potential impact on the human body and to reduce the product's overall weight. We also reduced the number of motors and improved various parts, such as by integrating substrates, thereby reducing power consumption by 15%. Furthermore, we reduced the product's environmental impact throughout its life cycle by greatly reducing the number of man-hours as well as the period of time required for software development through recycling-oriented hardware design (certified as an Excellent ECP for FY2014).

Case Studies in FY2013

Case Study 1: Reduction in MFP size

Toshiba TEC Corporation

The e-STUDIO 2550C series products are medium- and low-speed color multi-function printers (MFPs) designed to be compact and have excellent environmental performance.

We reduced the number of parts used as well as the thickness of plates and molded parts to produce an MFP with a product weight of 57.3 kg (53.4% reduction compared to the previous model) and a footprint of 33,925 mm² (34.4% reduction compared to the previous model), realizing the world's lightest, most compact MFP.

In addition, the newly developed low-temperature fixable toner can reduce power consumption by 60% compared to the previous model, achieving best-in-class energy-saving performance.
