On July 1st, Toshiba Corporation's Semiconductor Company and Storage Products Company consolidated to form Semiconductor & Storage Products Company.This page describes previous Semiconductor Company's environmental activities.
Waste Sent to Landfill 1 percent or Less
“Waste sent to landfill less than 0.5% (by weight)”*1 has been achieved at all manufacturing operations including overseas sites
Toshiba Semiconductor Company Group strives to achieve reduction of waste generated in association with its business activities and effective use of resources, as a project undertaken by the entire group.
Our goal is to reduce the total amount of waste generated by 24% (per production output normalized by deflator) in 2012, compared to the baseline 2000 emissions.
We achieved our target by various measures, including reusing once-used chemicals in the manufacturing processes that had been waste up until FY 2009.
All manufacturing plants both in and out of Japan have achieved the goal of ‘waste sent to landfill less than 0.5% by weight.’ For policies for waste sent to landfill less than 0.5% achieved in the overseas plants, refer to the action items below.
As for efforts toward effective utilization of resources, we promoted recycling of plastic, metal and other resources. In overseas plants, employees implemented thorough waste materials separation management and started recycling them as materials for cement production.
We are committed to making further efforts in more effective use of resources and reduction of waste.
- *1 "Waste sent to landfill < 0.5%" means that the final disposal rate or amount of waste sent to landfill after treatment is less than 0.5% of the total amount by weight of byproducts and other waste items generated (total waste discharged) as a result of business activities at each of Semiconductor Company Group's manufacturing sites worldwide. In addition, our non-manufacturing sites in Japan have achieved a final disposal rate of 1.0% or less.

- Action items taken to achieve “waste sent to landfill less than 0.5%” at overseas factories
- Sample measures for achieving “Waste sent to landfill less than 0.5%” at Toshiba Electronics Malaysia Sdn. Bhd., our manufacturing company in Malaysia
- Implementation of comprehensive waste materials separation activities
- Recycling of resin wastes at cement producers
- Recovery and recycling of rare metals
- Re-usage of goods delivery boxes and reels in manufacturing processes
- Screening of several disposal companies and coordination of selection criteria
⇒Establishment of recycling routes - Recycling of wasted abrasives that occupied 98% of waste at cement companies as of 2006
“Business process improvement” by 3R measures
Effective usage of limited resources has become increasingly important in our society. Semiconductor Company Group is pursuing the 3R policy in our business processes (reduce, reuse and recycle) which are necessary for creating a sustainable, recycling-oriented society. Here are examples of waste emission reduction measures at Oita Operations and Yokkaichi Operations.
- Example of waste reduction at Oita Operations
-
Oita Operations conducts biological treatment with bacteria in the waste water treatment facility, and had purchased industrial methanol (50% concentration) to feed those bacteria.
At the same time, methanol used in the manufacturing processes had been given waste treatment after recovery since impurities were dissolved within it.
However, after detailed studies, Oita Operations succeeded in diverting it as the feed for bacteria after administering treatment (diluting and other measures.) This measure contributed to reduction of waste methanol amount by 120 tons a year.
-
- Example of waste reduction at Yokkaichi Operations
-
Yokkaichi Operations had purchased around 700 tons of industrial sulfuric acid per year to adjust pH of the waste water of hydrogen fluorite.
At the same time, Yokkaichi Operations had produced mixed fluid of sulfuric acid and hydrogen peroxide used in the resist process, and sold 11,000 tons of the fluid to outside manufacturers every year.
Yokkaichi Operations succeeded in diverting the mixed fluid of sulfuric acid and hydrogen peroxide to pH adjustment of the waste water of hydrogen fluorite by administering treatment (diluting and other measures.) This measure succeeded in reduction of the purchase of sulfuric acid by 700 tons a year and waste by 539 tons a year.
-
“MOTTAINAI (too good to waste) activities” where all employees participate
Each business site of Semiconductor Company Group is developing 3R activities where all employees participate based on the MOTTAINAI spirit and reducing waste.
Here are examples from Oita Operations and Toshiba Electronics Malaysia.
- Opening of a Re-use Shop in Oita Operations
-
Oita Operations opened a re-use shop so that the employees can experience re-use in a more familiar and convenient manner. Used goods are available in the re-use shelves in the recycling center in the plant and the reuse shop on the internal website. The shop carries tools, parts, desks, chairs, lighting fixtures that were removed by the energy conservation activities and a large variety of other goods. Since it can be viewed on the website, many employees participate in reuse activities. Oita Operations also introduces reuse to unused goods at the employees’ homes, and the activities extended to participation in a bazaar at the autumn festival. Oita Operations will continue to pursue such 3R activities with this MOTTAINAI spirit.
- Available on the website
- Instant entries without concern about where to put the goods to be reused Anyone can view it any time.
- Reuse shelves in the recycling center
- Reuse shelves are placed in the recycling center to display and offer small supplies
- “Eco charity bazaar” at the autumn festival in the Plant
- All exhibits were sold out and profits were donated.
- Examples of reuse
-
- 400 fluorescent light bulbs removed for energy conservation by the Manufacturing Division
⇒To be used at the power zone - Reuse of surplus office supplies
- Reuse of desks and lockers by divisions that have transferred or are newly established
- Reuse of large paper files once they were electronically converted
- Reuse of tools and parts, etc.
- 400 fluorescent light bulbs removed for energy conservation by the Manufacturing Division
- “MOTTAINAI activities” overseas (manufacturing company in Malaysia)
-
Toshiba Electronics Malaysia has proactively developed “MOTTAINAI activities” since FY 2005. This concept has taken firm roots in the company. In addition to the energy conservation discussions among employees, introduction of energy conservation measures in the manufacturing processes and other environmental performance improvement, their 4S(*) activities have brought about significant improvement.
Toshiba Electronics Malaysia is communicating its activities to stakeholders, and explained the waste reduction programs, water recycling and energy conservation measures when stakeholders visited them in FY 2009
-
Visits by stakeholders
(*): Seiri, Seiton, Seiketsu, and Seisou meaning in English sorting (discarding un necessary things), straightening (keeping things orderly and available as needed), sanitation and sweeping (maintaining a clean workplace)
