LONDON, UK – April 28, 2021 – Did you know that globally more than 50 million^[1] tons of electronics that are thrown away each year and only a mere 17 percent is eventually recycled? Most of this ‘e-waste’ ends up polluting the environment by sitting in landfills or being incinerated. With annual e-waste expected to reach as much as 74 million tons by 2030, the global community has started taking steps to reduce consumption and minimise waste.

Driven by a desire to keep our planet clean for generations to come, Samsung Electronics regularly engages in eco-conscious efforts that are helping to establish a circular economy. The company is constantly exploring ways to reduce its products’ impact on the environment, including increasing products’ lifespans and spearheading efforts to recycle their resources.

In celebration of Earth Day 2021 (April 22), this special series shines a light on Samsung initiatives that are paving the way for a circular economy. Our first article took a closer look at how the company’s recycling campaigns are giving old phones new life. Here, we’ll examine how Samsung’s Visual Display Business is making its TVs more sustainable by adopting eco-friendly packaging and solar-cell-powered remote controls.

Today, innovation no longer focuses solely on creating a more convenient and efficient future, but a sustainable one as well. As such, leaders in the fields of science and technology are devoting their utmost efforts to making their products eco-friendly without compromising on performance.

Samsung consistently pursues innovations that allow it to make its products more environmentally friendly and recently developed a remote control that’s made using renewable plastic and powered by photovoltaic energy rather than disposable batteries.  The company also created an eco-packaging solution that repurposes TV boxes into  small-scale pieces of furniture. Samsung Newsroom recently sat down with members of the team behind the innovations that are making Samsung TVs more sustainable.

A Solar Cell-Powered Remote Control That Charges Itself Using Photovoltaic Energy

Even if you have a nice, big, high-performance TV in your living room, you won’t be able to fully enjoy its countless channels and manage the volume and other features without a remote control. When exploring ways to make remote controls more eco-conscious, Samsung’s developers focused their attention on disposable batteries.

“Supposing that a typical TV is used for around seven years, changing the batteries in its remote just once a year would mean that 14 batteries would get used and thrown out,” said Kwanyoung Kim, an engineer. If we apply that number to Samsung Electronics’ expected annual global TV sales, it amounts to approximately 99 million discarded batteries. If we apply it to annual TV sales overall, it adds up to nearly 3.1 billion batteries.^[2]

Rather than using disposable batteries in the remote, the engineers decided to go with a self-charging battery instead. Many charging methods were considered, including one that harnessed the kinetic energy that’s created when the remote is shaken, and one that utilised the vibrational energy that’s created when the microphone picks up sounds. As Kim explained, at the end of the day, the optimal charging solution turned out to be a solar cell.

“Even when we aren’t watching our TV or using our remote, we usually have the lights on, except when we are sleeping. This makes light an easily accessible charging solution,” said Kim. “If we substituted disposable batteries with self-charging solar cell batteries like the one we’ve developed, it would amount to reducing up to around 6,000 tons of greenhouse gas emissions per year.”

How exactly does the remote control generate energy from the fluorescent lights in our living rooms? Put simply, its solar panel takes in photons from light, which react with the electrons in the solar cells to create electricity. The difference between outdoor panels and indoor panels is the spectrum of light being used. “You can’t get as much light indoors compared to sunlight,” added Kim, “so we decided to utilise solar cells that generate energy even in low-light indoor environments.”

Increasing Electricity Efficiency Makes Solar Cell-Powered Remote Controls Possible

Because the amount of electricity that could be created by converting light energy simply wasn’t enough, it would be impossible to generate enough energy for the remote control using solar cells alone. This led the engineers to create a low power remote control instead of searching for ways to increase energy production.

The engineers succeeded in increasing the remote control’s energy efficiency by reducing its power consumption by 86 percent.^[3] They did this by taking users’ TV watching patterns, the number of times they pressed their remote control’s buttons, and usage time into account. As Kim explained, the solar cells in the final product “can provide up to 70 percent of the power used by the remote control.”

Making the design of the typical TV remote control, which has remained unchanged until now, more sustainable was no simple task. The color of the solar panel was already determined, so it was difficult to apply various colors to the remote control’s design. One of the team’s key concerns was that the remote control’s panel would need to be raised up high in order to be charged via light. “The solar panel itself is gray, so if we used a color other than black for the battery, it wouldn’t go well with the overall product design,” said Kim. “We also needed the design to encourage consumers to do their part to help the environment.”

The remote control is so small that you could ask whether it even needs to be energy-saving. If you asked the developers, they would tell you that, because the final product is even more eco-conscious than they anticipated, its design was undoubtedly meaningful and their efforts were worthwhile. Their ultimate goal is to develop a solar cell-powered remote control that is capable of charging itself up to the full amount of energy that it needs.

“TV remote controls are frequently used products, and our aim is to create the kind of remote that offers users meaningful value, and can be a deciding factor when purchasing a TV,” said Kim.

Use of Recycled Plastic Materials Contributes to a Huge Reduction in CO2 Emissions

Solar panel technology isn’t the only thing that makes Samsung’s new remote control especially eco-friendly. Indeed, the plastic material used to create this roughly 40g device is comprised of 28 percent recycled plastic. Samsung has been utilising recycled plastic in its products for a long time, and has received various certifications for its eco-friendliness. Now, the company has expanded its scope by applying recycled materials to accessories like remote controls as well.

Recycled plastic is enticing because it reuses resources, but not everything about it comes easily. For a start, unit prices go up during the manufacturing process. While Samsung’s VD business does utilize plastic waste that has been collected in Korea, the volume is so small that additional resources need to be imported from overseas. This process causes costs to go up by five percent at the least, and 10 percent at the most.

“The amount of plastics used by Samsung Electronics’ VD Business alone is 250,000 tons,” said Seungsan Han, an engineer and colleague of Kim’s. “Even substituting 10 to 30 percent of that with recycled plastics would require 30,000 to 70,000 tons.”

Despite those costs, Samsung is committed to increasing its usage of recycled materials based on their clear eco-conscious benefits. According to Life Cycle Assessments (LCA), a methodology for assessing environmental impact, products made using approximately 28 percent recycled plastics emit 31 percent less CO2 than products made from non-recycled plastics. ^[4]In an effort to maximise its use of eco-friendly materials, Samsung also explores ways to utilise waste that has been thrown indiscriminately into the sea. “Twenty percent of the waste that gets thrown into the sea is made of Polyethylene terephthalate,” said Han. “The marine waste plastic obtained here is called OBP (Ocean Bound Plastic) material, which can be applied to the exteriors of electronics. Using OBP in this way helps discourage marine pollution while promoting efforts to protect the environment.”

More Interest in Eco-Friendliness Widens the Range of Recycled Materials

Samsung has long practiced eco-conscious business management, and has been developing eco-conscious products and technologies for several years. As a result, the company is now capable of producing high-quality products using recycled materials, while keeping unit prices at manageable levels.

Samsung currently utilises recycled plastics when producing many products, including not just its new, solar cell-powered remote control, but other remote controls as well. Eco-conscious materials are used in the company’s monitors, signage stands, and back covers, too. “In the future, the use of recycled materials will be expanded to include more Samsung TV products,” said Han. “With 2030 being the year when we hope to reach our ultimate achievement, we will keep increasing our use of recycled plastics each year.”

Eco-Packaging: What Would Be Trash Becomes Small Furniture

Increasing products’ efficiency and using recycled materials are clear ways to become more eco-conscious. Now, efforts are being made to address the eco-friendliness of products’ packaging, which would usually be thrown away. Allowing consumers to use their TV’s packaging to make small furniture, the eco-packaging that Samsung introduced in 2020 is a perfect example of this point.

The TVs’ eco-packaging first began as a project of C-Lab, Samsung’s in-house startup incubation program. The C-Lab developers were wondering how best to recycle TVs’ packaging when they noticed that Serif TV users were placing their set-top box, small furniture, and electric devices under their TV as if it were a cabinet. This led them to the idea to use TVs’ strong cardboard packaging to make small, long-lasting furniture, which became the foundation for a new type of ‘eco-packaging.’

Eco-packaging’s manufacturing process is mostly the same as that of other packaging, but also includes the application of a dotted pattern that helps users assemble the packaging into furniture. Although adding the dotted patterns sounds easy and could be achieved by simply printing graphics, the task presented some difficulties as well. The thicknesses and specifications of the cardboard boxes varied slightly by country, which entailed continuous communication with various parties. “Although we faced many difficulties when making the eco-packaging, we managed to do a great job thanks to the efforts of many people, including the Graphics Team,” said Sungdo Son, a Samsung Electronics designer.

Easy to Make, Beautiful to Behold

Simple steps for assembling the furniture can be found on the website embedded in the QR code printed on the side of the eco-packaging. “The website, which was recently updated, not only offers instructions on how to make furniture, but also provides an overall introduction to eco-packaging with relevant videos,” said Son. “We’ve arranged the website based on difficulty, so users can choose the type of furniture they’d like to make depending on their skill level.”

The cardboard furniture displayed on the website are all items that were chosen by designers who actually tried making them themselves. “When we focused on aesthetics, it became difficult to make the furniture, and the designs often didn’t end up being very useful,” said Son. “On the other hand, when the furniture was too easy to make, it didn’t look so great. We also got rid of any furniture designs that could potentially create safety issues.”

Samsung’s safety- and environmentally conscious eco-packaging has gone beyond lifestyle TVs and is now being applied across the company’s entire 2021 TV lineup. The employees involved in developing the eco-packaging hope that it will eventually reach much more consumers, and will help encourage them to contribute to environmental conservation in any way they can. “Samsung is known for producing technologically advanced products, but I want others to know that Samsung also believes that little things like these matter, and we are working on them as well,” said Son.

In order to contribute to tackling this global crisis, Samsung Electronics has been devising sustainable ways to respond to climate change across all aspects of its business operations. Read on to learn more about the measures implemented by Samsung that aim to provide everyone with a better, more sustainable, tomorrow.

Renewable Energy Usage Reaches 100% in the U.S., China and Europe
In June 2018, Samsung committed to having all its worksites in the U.S., China and Europe rely exclusively on electricity sourced from renewable sources by 2020. Thanks to the unrelenting efforts put in hereafter, in 2019, 92% of the energy used in these worksites was generated by renewable sources; and in 2020, the company achieved its goal of 100% renewable energy for these worksites. Samsung’s efforts to use renewable energy continue across various other regions around the world, including Korea.

Solar panels at parking lots in Samsung campuses in Suwon and Giheung, Korea

Across various worksites in Korea, Samsung has installed solar and geothermal facilities for renewable energy production. At the company’s Suwon, Giheung and Pyeongtaek campuses, geothermal power generation facilities have been installed across the campuses’ parking lots, buildings, roofs and new construction sites.

In each of its operational regions around the world, Samsung has developed and is implementing specific regional action plans in order to promote renewable energy usage, including Renewable Energy Certificate (REC) purchasing and renewable power purchase agreements (PPA). Some examples of these region-specific action plans are the signing of a renewable energy supply contract with wind and solar power suppliers in India; the purchase of renewable energy certificates in Mexico; and the specific percentages of renewable energy set for the company’s worksites in Brazil.

Eco-Conscious Products for Everyday Life 

In 2008, Samsung Electronics established its corporate Eco-Council and began holding regular meetings across its various business units to support the development of energy-efficient products. By sharing technologies that help reduce energy consumption and follow eco-conscious trends, the company’s many teams have managed to develop products that simultaneously maximise performance and minimise energy consumption. The results achieved through these co-operative initiatives have also been supported by company-wide efforts to develop highly energy-efficient products.

On January 6, Samsung Electronics unveiled its 2021 TV product portfolio at its virtual First Look event, and also announced the company’s latest long-term sustainability programs that include the inclusion of solar cell-powered remote controls and the reduction of product carbon footprints through the use of recycled materials.

Samsung’s 2021 Neo QLEDs will come with a new solar cell-powered remote control that can be recharged through indoor or outdoor lighting, or USB. This innovation will help prevent the wastage of around 99 million AA batteries over the course of seven years of usage^[1].

Samsung is also making efforts to reduce the emission of greenhouse gases throughout the TV product lifecycle through the application of recycled plastics. Samsung has been using recycled materials in the rear covers of their monitors and signage and is now planning to expand their usage into even more components across the company’s visual display product portfolio. Through various efforts including expansion of its Eco-Packaging Design to all 2021 Lifestyle TVs and the majority of the Neo QLED line, Samsung’s Visual Display Business is aiming to reduce greenhouse gas emissions by 25,000 tons annually, equivalent to the absorption of greenhouse gases by 3.8 million 30-year-old pine trees over the course of a year^[2].

By using Galaxy smartphones everyday, users, too, can help protect the environment. Polyketone, a material that contributes to the reduction of carbon monoxide (greenhouse gas), has been used by Samsung on their Galaxy smartphone and tablet products since 2016. Most recently, in order to reduce the product’s carbon footprint, Samsung applied Polyketone to the side key internal brackets of its Galaxy S21 series.

By pursuing a minimal packaging design and changing the materials used throughout the entire product lifecycle – from manufacturing and distribution through to usage and disposal – Samsung’s Galaxy S21 smartphone have received the ‘Reducing CO₂’ certificate from the Carbon Trust^[3], acknowledging the reduction of greenhouse gases the Galaxy S21 produces compared to the previous model.

In addition, the company has reduced the standby power consumption of its flagship Galaxy smartphones’ chargers since 2012 to press the problem of power waste. In the year since, the company has applied this environmentally conscious enhancement to the chargers of devices throughout its product range, and is currently aiming to reduce the standby power consumption of chargers to zero.

Samsung’s dishwashers DW80R9950UG, DW80R7060UG

As for Samsung’s home appliances, the mission to reduce products’ energy consumption is ongoing. Samsung’s dishwashers are also energy-efficient. In 2021, the DW80R9950UG and DW80R7060UG models sold in the U.S. were included in Energy Star’s 2021 Most Efficient Dishwashers list, satisfying the criteria of annual energy use of less than 240 kWh per year and water consumption less than 3.2 gallons per cycle for standard-sized models. This translates to 67 kWh per year in energy savings and 387 gallons per year in water savings compared to a conventional product.

In the company’s Semiconductor business, remarkable sustainable progress has also been made. A total of nine key memory products – four DRAM solutions, three solid state drives (SSDs) and two embedded storage (eStorage) devices – have received the Carbon Trust’s Product Carbon Footprint (PCF) certification. In addition to this, the 512GB eUFS 3.1 has been recognised with the semiconductor industry’s first Reducing CO₂ label.

Samsung has also been making efforts towards sustainability right from the manufacturing stage of packaging materials for the Portable SSD T7 Touch by developing an eco-friendly pulp material to replace plastic tray components. By using one-third less tray packaging, replacing the plastic trays with eco-friendly pulp material and minimising greenhouse gas emissions throughout its production, the company saved approximately 84 tons of carbon.

Receiving Accolades and Acknowledgement for Eco-Efficiency

Six Samsung refrigerator models sold in the U.S. have been awarded the 2020 ENERGY STAR Emerging Technology Award by the U.S. Environmental Protection Agency (EPA). Every year, the EPA, through its ENERGY STAR Program, chooses one or two innovative technologies for their Emerging Technology Award. In 2020, the awards recognised six Samsung refrigerator models that successfully met three strict performance criteria: (1) super-efficient compressors; (2) low greenhouse gas blowing agents for their insulation; (3) low greenhouse gas refrigerants. Samsung digital inverter compressors use around 30% less energy than single-speed induction motor compressors, and thus also help contribute to the reduction of greenhouse gas emissions.

Samsung will continue to monitor the ongoing climate change situation and pursue energy-efficient products and manufacturing processes in order to reduce greenhouse gas emissions and promote the usage of renewable energies.

The company will also continue to pursue its policies of increasing energy efficiency and minimising the usage of resources so that its users can rest assured that they are doing their part to help mitigate climate change with products that require low electricity and provide high performance.
