Efficient Use of Resources

Toshiba Group promotes 3R (reduce, reuse and recycle) initiatives for products to reduce resource consumption and increase incoming and outgoing recycling.

Toshiba Group's 3R initiatives for products*

In order to create a sound material-cycle society, there is a need to reduce the amount of resources extracted and discharged as waste throughout the product life cycle. Toshiba Group is promoting 3R initiatives for products aimed at reducing waste, increasing incoming recycling, and improving outgoing recycling. We are also taking measures to promote design for 3Rs of product and recycling systems and are implementing activities to reduce the environmental impact of our products throughout their life cycles.

Reduce, reuse and recycle

Waste reduction

We achieve waste reduction through various means, including reducing the amount of resources used to manufacture products (reducing weight and size) and extending product lives (including upgrades and maintenance).

Incoming recycling

Incoming recycling refers to the application of recycled materials in products. We will work to improve our incoming recycling rate by increasing our use of recycled materials, plant-derived materials, and reusable parts.

Outgoing recycling

Outgoing recycling refers to the collection and recycling of end-oflife products. By promoting designs for reusing and recycling materials, we improve outgoing recycling while simultaneously improving the system design for recycling end-of-life products further.

Increase in the percentage of resource savings

Results of FY2015

Under the Fifth Environmental Action Plan, we aim to further increase the amount of resources conserved to 1.5 times the FY2010 level. In FY2015, 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 430,000 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 240,000 tons, or by 30% compared to previous product models. As a result of reduced production of LCD TVs and other digital products, we were unable to achieve our goal.

Future initiatives

We will continue to promote resource-saving designs for all products with the aim of further reducing resource consumption.

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.

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).

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.

Increased use of recycled plastics

Toshiba Group is promoting initiatives to recycle plastic waste generated by end-of-life products.

Results of FY2015

As a result of reduced production of home appliances, the amount of recycled plastics used in Toshiba Group products decreased to approximately 2,400 tons in FY2015. However, use of recycled plastics in MFPs and industrial air conditioners continues to increase. The percentage of recycled plastics relative to the total amount of plastics used in products* was 9.7%, greatly exceeding the initial goal (3.0%).

Future initiatives

In order to further increase the percentage of recycled plastics used in our products, we will secure a supply of waste plastics as well as develop new uses for recycled plastics in all product groups.

Case Study 2: Progress in sorting waste plastics

Nishinihon Kaden Recycle Corporation

In addition to product design initiatives, such as using recycled plastics for new product parts, Toshiba Group is also working to ensure sufficient supply of recycled plastics to expand their use. Nishinihon Kaden Recycle Corporation has developed and introduced a process for collecting high-purity, single material plastics from crushed mixed plastics. The process makes use of a near-infrared sensor to sort and separate ABS and HIPS resins. Then, brominated flame retardants are removed to ensure a supply of recycled plastics that meets the RoHS* Directive. In addition, a machine polishes the surfaces of collected plastics to further increase their purity. Recycled plastics obtained in this manner are used in home electrical appliances and other products.

Case Study 2: Use of recycled plastics in refrigerators

Toshiba Home Appliances Corporation

The percentage of recycled plastics used in Toshiba's VEGETA/GR-F56FXV refrigerator has significantly increased compared to the equivalent model for the previous year (GR-E55FX). The main reason for this increase is that recycled plastics were used for the parts embedded in polyurethane and the parts inside the machine chamber that do no affect product appearance. In addition to design improvements, improvements in recycling processes, including an increase in the supply, development of new recycled materials, and transport to overseas production sites, have made it possible to use such recycled products.
