Reducing the total waste volume

Reducing the total waste volume

Toshiba Group is working to reduce waste generation by minimizing the volume of waste generated per unit activity, which indicates business process efficiency improvement, as well as by reducing the total volume of waste to a level below the Earth's environmental capacity.

Results of FY2016

In FY2016, the total volume of waste generated per unit activity was 83% compared to that of FY2010, exceeding the initial target. The volume of waste (excluding that of objects with value) totaled 77,000 tons, which is 33,000 tons lower than the initial target. Out of the total volume of waste, the amount of hazardous waste was 4,105 kg in FY2000, 490 kg in FY2014, 342 kg in FY2015, and 350 kg in FY2016.

Future initiatives

In the Sixth Environmental Action Plan, Toshiba Group aims to reduce the volume of waste per unit activity in FY2020 by 4% compared to FY2013 and to reduce the total volume of waste to 52,000 tons. We will promote dialogues with stakeholders inside and outside the Group and create diverse networks for resource recycling.

Reducing the final disposal volume

In order to create a sound material-cycle, sustainable society, Toshiba Group is working to achieve zero waste emission- an initiative of reducing final landfills to zero by promoting the reuse and recycling of waste.

Results of FY2016

The percentage of final landfills to the total volume of waste generated by Toshiba Group in FY2016 was 0.55%, falling short of the initial target of 0.5%, though an improvement of 0.22% compared to FY2015. Out of the final disposal volume, the amount of hazardous waste was 169 kg for FY2000, 12 kg for FY2014, 6 kg for FY2015, and 3 kg for FY2016.

Future initiatives

We will maintain the current status at the sites that have reduced the percentage of final landfills to 0.5%, and continue our efforts at sites that have not yet achieved the goal. We will manage progress made and measures taken at different sites through the Toshiba Group's environmental audit system.

Promoting recycling

In FY2016, Toshiba Group recycled 209,000 tons of resources. 97% of the total volume of waste generated was reused effectively as various resources. The recycled resources consisted mainly of scrap metal and cinders, and 96% of them were used effectively for material recycling (recycled into materials for products), and the remaining 4% for thermal recycling (heat recovery). In the future, Toshiba Group will continue to increase the total volume of resources recycled and at the same time will strive for higher quality recycling chiefly by increasing the percentage of resources recycled into materials.

Case Study 1: Reducing metal waste through 3R activities at a semiconductor manufacturing site

Toshiba Semiconductor (Thailand) Co., Ltd.

Toshiba Semiconductor (Thailand) Co., Ltd., which manufactures small-signal devices and optical devices, faced the challenge of how to reduce the amount of metal waste. To overcome this challenge, the company actively implemented 3R measures in cooperation with its mother plant, the Himeji Operations-Semiconductor, to reduce the amount of waste, including lead frames and mold resin.

of lead frames

• Reducing generated waste by 25.3 t/year by replacing conventional lead frames with high-density-type frames (material utilization efficiency: 242% of the previous level)
• Reducing generated waste by 1.6 t/year by making the shape of mold resin smaller (material utilization efficiency: 466% of the previous level)

The company also promoted recycling of electronic parts, including spray cans and batteries, to achieve its goal of reducing the final disposal amount to zero to meet Thailand's administrative standard (DIW*). As a result, the DIW awarded the company the “Zero Waste to Landfill Achievement Award 2015.”

Case Study 1: Initiative for reducing waste through use of ICT solutions

Toshiba Solutions Corporation

Toshiba Solutions Corporation implements ICT solutions for work style innovation on its own and greatly contributes to effective use of resources. Expanding the use of thin clients specially designed to provide the minimal necessary functions to users (such as data input and display on network-connected devices) while centrally managing applications and files on servers has helped to increase reuse of existing PCs and to reduce disposal of such PCs. The company also actively uses ICT infrastructure and equipment in meetings, thereby reducing the amount of paper documents printed and distributed. As a result of these initiatives, the company reduced the amount of waste by 30% in the five years up to and including FY2014.

Case Study 1: Initiatives for waste reduction at overseas sites

Westinghouse Electric Company

Westinghouse Electric Company held a waste audit event for members of various divisions to jointly confirm the content of waste from its business sites. This event led to reductions in waste such as paper towels and plastic containers. A video of the event was effectively used for employee training, bringing about results by changing employees' awareness about the need to use resources effectively. As a result of these initiatives, the company substantially reduced the volume of waste generated and final disposal volumes over the five years leading up to FY2013, lowering the former to half and the latter to one-fifth.
