Curbing the Amount of Waste, etc. Generated by the Sharp Group

Sharp has been working to reduce waste and to recycle as much of it as possible in an effort to contribute to building a circular economy.

In fiscal 2022, the amount of waste, etc. generated by the Sharp Group decreased by 27% compared to the previous fiscal year to 86,000 tons, due to disposal of old equipment and expansion of production. The amount of recycling decreased by 15% from the previous fiscal year to 62,000 tons. Meanwhile, by reducing landfill disposal rates at overseas bases, the Sharp Group’s final landfill disposal rate was 0.43%, thus achieving zero discharge to landfill* on a global scale.

Sharp will continue to strengthen waste-reduction efforts at overseas bases while maintaining global zero discharge to landfill.

  • Sharp defines “zero discharge to landfill” as a final landfill disposal rate of less than 0.5%. Final landfill disposal rate (%) = Amount of landfill disposal ÷ amount of waste, etc. generated × 100.

Appropriate Storage and Management of PCB Wastes

In Japan, Sharp properly stores and manages waste PCB (polychlorinated biphenyls) in accordance with the Act on Special Measures Concerning Promotion of Proper Treatment of PCB Wastes. Sharp has completed processing of all high-concentration waste PCB in fiscal 2022. As for the remaining low-concentration waste PCB, Sharp is on track to finish processing them at the earliest date possible.


Reducing Consumption of Plastic

SPC, a Sharp production and sales base in the Philippines, reuses the plastic bags that are generated as waste in the LCD TV production process. The plastic bags used for wrapping LCD TV parts were previously disposed of as industrial waste, but by collecting them during production they can now be used in the packaging process of finished products that are shipped out. This has allowed SPC to reduce monthly plastic bag usage by approximately 12,000.

Toward Making Better Use of Resources

Sharp and Kansai Recycling Systems Co., Ltd.*2 have joined forces to make effective use of resources and to improve recycling efficiency.

The motor of a washing machine uses copper windings. Separating and recovering materials like copper can boost the value of resources. Conventional equipment used a rotary blade to cut the copper winding, but the dust resulting from the cutting could potentially have an adverse effect on the operator’s health or the functioning of the machine. In addition, to prevent aluminum—an increasingly common winding material—from getting mixed with copper, aluminum windings were dismantled by hand in a separate process.

In fiscal 2022, we introduced a multi-axis robotic arm to automate the cutting/recovery process. The robot cuts and recovers the copper windings and aluminum windings from the motors, using a dedicated cutting device for each type of material. Switching to a dust-free cutting method has greatly improved the work environment. Using a single piece of machinery to separate copper and aluminum has reduced the processing time per motor by about 30%.

Design-for-Recycling Training

Sharp is committed to considering the whole life cycle of products it manufactures. Together with Kansai Recycling Systems—where four kinds of Sharp products are recycled—Sharp has been holding design-for-recycling training for product planners and designers. In April 2023, 13 people, including those in charge of white goods, took part in the training.

The training emphasized the importance of designing products with an eye to their eventual recycling, with a focus on plastic material recycling. It also included a tour of the recycling plant. Participants practiced dismantling a fully automatic washing machine that had been used for over a decade. They saw how the ease of dismantling depends on the fastening method used—for example, whether the product is held together with screws. They also learned the importance of separating components into discrete material types.

Participants gained a better understanding of the recycling process, and expressed a desire to focus on achieving both quality and recyclability in their future designs. We will continue to foster awareness within the company so that we can pursue manufacturing that considers everything from material selection to end-of-life recycling.

Reusing and Recycling Copiers and MFPs in Japan

Sharp is reusing and recycling copiers and MFPs collected both through Sharp distribution channels and through common industry channels. The company is also collecting used toner cartridges and remanufacturing them to the same quality standard of new products, thus assuring that customers will always get the same high quality. Sharp designs its toner cartridges for easy reuse and recycling. This ensures durability and reduces the amount of time needed to reprocess used cartridges.

Recycling Used Products Overseas

North America

In 2007, Sharp’s American manufacturing and sales base SEC established MRM (Electronic Manufacturers Recycling Management Company, LLC)*1 to manage recycling of AV products. Growing nationwide efforts have seen a total of 2,900 collection points established for used products. MRM operates in accordance with the laws and regulations of each state and recycled a total of 60,000 tons of used products in fiscal 2022.

  • *1 MRM is a joint venture with Panasonic Corporation of North America and Toshiba America Consumer Electronics, LLC.


The EU WEEE Directive*2 (2012/19/EU) stipulates that the manufacturer is responsible for collecting and recycling products shipped within the EU. Each Sharp European sales base collaborates with established recycling entities in the EU sales region to meet this requirement. Efforts are also made to reduce the volume of landfill waste by taking into account regulations governing packaging materials and batteries.

Expanding Closed-Loop Plastic Material Recycling Technology

In recycling materials, such as when end-of-life plastic is reused to make new products, the open-loop material recycling scheme is commonly adopted. It involves reusing recycled materials to make things like daily necessities and sundries. The majority of these are used only once and disposed of as municipal waste.

As opposed to this type of recycling, Sharp and Kansai Recycling Systems Co., Ltd.*1 jointly developed closed-loop plastic material recycling technology with a view to making better use of finite resources and reducing waste. This technology enables the repeated recovery of plastic from used consumer electronics products as well as the reuse of that plastic in parts of new consumer electronics products. The technology has been in practical use since fiscal 2001, when the Act on Recycling of Specified Kinds of Home Appliances (Home Appliance Recycling Act) was enacted in Japan.

Sharp has been striving to make more plastic recyclable through the development of new technologies. These include a technology for recovering high-purity polypropylene (PP) from mixed plastic parts and parts that contain metal; a technology for improving the properties of recovered PP/HIPS*2 and PC+ABS*3 materials so that their quality is on a par with that of virgin materials; a technology that gives materials added value by imparting properties such as flame retardancy, weather resistance, and an antibacterial property, with the aim of expanding applications for recycled plastic; and a quality-control technology for ensuring optimal quality. Thanks to the development and introduction of these technologies that integrate everything from recovery to quality control, Sharp has been able to establish closed-loop material recycling to produce high-grade recycled plastic.

Developing Recycled-Plastic Material with Added Value

In response to the increasing seriousness of pollution from used plastic, countries are enacting and enhancing various laws and regulations related to plastic recycling. There is a push to move away from the traditional linear economy, characterized by mass production, mass consumption, and mass disposal, and towards a circular economy, characterized by limited input and consumption of new resources and minimal waste production. In Japan, as well, society’s attitude towards plastic usage has changed significantly, as evidenced by the enforcement of the Act on Promotion of Resource Circulation for Plastics*. The Act focuses on resource recycling across the entire life cycle of plastic products, making it increasingly important that plastic materials are properly disposed of and recycled.

Against this background, Sharp is pursuing greater recycling of used plastics, not only through horizontal recycling, in which used plastics are made as good as new material and incorporated into the same parts as they were originally used, but also through upgrade recycling, in which the recycled plastic is given added value with flame retardancy, weather resistance, or high stiffness.

In fiscal 2022, Sharp developed mass-production technology for recycled flame-retardant polypropylene and used the material in the internal parts of ceramic fan heaters. Polypropylene recovered from used home appliances is given the physical properties, flame resistance, and long-term durability demanded in home appliances using Sharp’s own formulation technology.

Recycled flame-retardant polypropylene is difficult to make using conventional methods. This is because it requires mixing recovered polypropylene with a thermally decomposable flame retardant and multiple modifiers under high temperature. Sharp’s new formulation and optimized process have enabled the mass production of high-performance, high-quality recycled flame-retardant material. This recycled material can be used in place of metal in parts that require a high level of safety, such as those used around power switches and heat sources. The practical application of this recycled plastic material holds promise for lighter and cheaper products, while also curbing the generation of waste plastic.

Going forward, Sharp will develop recycled materials that use no environmentally harmful substances such as halogen compounds, thereby contributing to a circular economy.

  • *This law is focused on comprehensive plastic recycling across the entire life cycle of plastic-containing products, encompassing everything from manufacturer product design and production to waste disposal (effective as of April 1, 2022).

Effectively Using Water Resources

Fiscal 2023 Objectives
  • Improvement rate of water intensity: 10% (baseline year: fiscal 2021)

Sharp’s Stance on Water Resources

Water resource problems are arising on a worldwide scale with the increase in the world’s population, the economic growth of developing countries, climate change, and other factors. Sharp is striving to make effective use of water resources in line with the environmental conservation guidelines stipulated in Sharp’s Basic Environmental Philosophy, the Sharp Group Charter of Corporate Behavior, and the Sharp Code of Conduct. In particular, Sharp recognizes that securing the water resources necessary for the production of LCDs and other electronic devices is a serious issue that could affect business continuity. That is why Sharp is pursuing the reduced use of new water and an increased use of recycled water.

Reducing the Amount of New Water Used and Using More Recycled Water

The volume of new water used by the Sharp Group in fiscal 2022 decreased by 6% compared to the previous fiscal year to 10.2 million m3. To minimize the effects on business continuity of the risk of water shortages, Sharp assesses water risk at its plants using the Aqueduct assessment tool developed by the World Resources Institute (WRI). SATL, Sharp’s production base in Thailand, is located in an area of highest risk. It is therefore reducing its use of new water by recycling water discharged from the production process and other sources. The Kameyama Plant (Kameyama, Mie Prefecture, Japan) and the Mie Plant (Taki District, Mie Prefecture, Japan) require a large amount of water in the production process for LCDs and other products. All of the water discharged from the production process is collected and reused via a closed-loop recycling system adopted at both plants. Through measures such as this, the Sharp Group is maintaining a recycling rate* of at least 60%. Looking ahead, Sharp will pursue further water-use efficiency worldwide and boost production efficiency in accordance with business expansion.

In fiscal 2022, there were no litigation issues, fines, or penalties due to violations of water-related laws and regulations. There were also no serious water-related accidents.

  • Recycling rate = Amount recycled ÷ (amount of new water + amount recycled).

Closed-loop Water Recycling System

The Mie Plant (Taki District, Mie Prefecture) has adopted a closed-loop water recycling system to repeatedly recycle the large amount of water used for the production of displays. The water discharged from the production process contains chemicals that must not be released from the plant untreated. All of this water is collected and goes through steps such as passing through filters and biofiltration (the natural decomposition of chemicals using microorganisms), before being purified with dedicated equipment. The resulting water is used repeatedly in production.

Closed-Loop Water Recycling Flow


Reducing Water Usage at Overseas Bases

At SATL, a production base in Thailand, large volumes of water are discharged from the production process and restrooms. This water was previously released into a nearby river after being properly treated. But now SATL is using newly installed water recycling equipment to purify that water and use it in the production process. The greywater* generated by this recycling process is kept in storage tanks and used for restrooms and for watering the factory’s green areas. SMM, Sharp’s production base in Malaysia, is using rainwater tanks to reduce the amount of water it requires. Large tanks installed in the plant collect rainwater that is used in, for example, air conditioner cooling equipment and restrooms. Thanks to these efforts, SATL and SMM have been able to reduce the consumption of clean water by about 88,000 m3 per year.
