Samsung Electronics Co., Ltd., the world’s leading TV manufacturer for 16 consecutive years, announced that its 2022 Neo QLEDs earned the ‘Reducing CO2’ certification from the Carbon Trust in recognition of its efforts to reduce its carbon footprint.

The Carbon Trust is a global climate consultancy driven by the mission to accelerate the move to a decarbonised future. The ‘Reducing CO2’ certification signifies that a product’s carbon footprint is reducing year-on-year. It evaluates the amount of GHG (Greenhouse Gas) generated throughout the entire product lifecycle using internationally recognized standards[1].

This year, 11 models across Samsung’s 2022 TV lineup, including three Neo QLED 8K models, three Neo QLED 4K models, two QLED models, two Lifestyle TV models, and one Crystal UHD TV model, obtained the certification by reducing the weight of the product and the power consumption during the use phase.

Samsung has long been committed to not only driving product innovation but also shaping and implementing environmental sustainability technologies. During Samsung’s keynote event at CES 2022, Jong-Hee (JH) Han, Vice Chairman, CEO and Head of Samsung Electronic’s Device eXperience (DX) Division, unveiled the company’s vision of “Together for Tomorrow”, highlighting Samsung’s commitment to creating a sustainable future and driving collaboration as part of the global community to preserve our planet.

As part of the initiative, Samsung’s Visual Display Business is set to use around 30 times more recycled plastics to produce its display products than it did in 2021. Samsung also revealed its plan to expand the use of recycled materials in all of their mobile and home appliance products by 2025.

In addition, Samsung has been adopting various sustainable practices to minimize the environmental impacts throughout its products’ lifecycles. The company’s ‘Eco-Packaging’ program – which allows consumers to upcycle the packaging for TV products into versatile pieces of furniture – has been upgraded this year with product packaging using 90% less ink while also removing the staples during production.

Samsung has also expanded the SolarCell Remote, which eliminates battery waste with built-in solar panels, to all TV models in 2022. Additionally, Samsung has developed and applied a new material, made with repurposed ocean-bound plastics, to a 2022 high resolution monitor S8 to reduce marine waste and minimize the environmental footprint.

“As the market leader for 16 consecutive years, Samsung is not only focused on the technological advancements, but innovations around human-centric technology and the environment,” said Seokwoo Yong, Executive Vice President and Head of R&D Team, Visual Display Business at Samsung Electronics. “Samsung will continue to implement various sustainability initiatives and eco-conscious activities in line with its ‘Going Green’ vision.”

Horticulture LED Driving the Future of Farming

On the industrial scale, indoor farms are increasing in popularity, since they are better equipped to overcome spatial constraints and extreme climates. In such indoor farms, artificial light plays a crucial role in efficiently managing the rate of plant growth.

Drawing upon its LED technologies developed for other lighting markets, Samsung launched its Horticulture LED lineup in May of last year to provide advanced lighting solutions to indoor farms. LED lighting is more efficient and has a longer lifespan than previously existing artificial lighting solutions. It is also easy to control the light spectrum of LED lighting and LED solutions are becoming a more attractive option for indoor farms.

Different wavelengths of light can affect plants in different ways. For example, wavelengths of 430 to 700 nanometers are required for photosynthesis, a wavelength of 450 nanometers promotes germination, 660 nanometers stimulates growth, and 730 nanometers or more helps plants to bloom and produce fruits. It’s thanks to these properties that red wavelengths (about 600~750 nanometers) and blue wavelengths (about 400~450 nanometers) have been the prevailing trend in indoor farms.

Recent developments have also emphasized the importance of green light with a wavelength of 550 nanometers, with findings that it can penetrate the lower canopy and thus increase the photosynthesis in plants found there. Since this was observed, interaction with a blue wavelength is now actively being studied also.

Based on this research, Samsung released its White LED package last November, with an extensive spectral range, including growth-boosting blue and red wavelengths. Full-spectrum LED lights can increase the nutritional value of plants and deter disease and pests. The bright white light can also create a more pleasant work environment than narrow spectrum alternatives, allowing farmers to monitor growth and inspect for disease with relative ease.

The package is designed to deliver strong reliability, even alongside the use of chemical fertilizers or under hot and humid conditions. The package is also competitive in price when compared to red LED products, helping to reduce the cost of establishing lighting systems in indoor farms.

Samsung raised the photon efficacy level of white LED packages to the highest in the industry, thus reconfirming the company’s leadership in this field. As a result, lighting manufacturers can use 30 percent fewer packages in each luminaire to achieve the same efficacy level as other lighting equipment, ultimately reducing the costs for indoor farms.

Packages can be selected according to the types of plants and the facility’s requirements. Samsung Electronics offers five white LED packages and one white LED module. The company has also designed one blue package and two red packages with a single wavelength.

As Will Chung, a researcher in the company’s Lighting Marketing Group (LED), explained, “Although it’s been less than two years since Samsung Electronics started its horticulture LED business, we’ve already received lots of positive feedback from the market for developing high-quality LED technologies. We’re committed to developing more innovative products that support convenient food production, and will continue to enhance our offerings with testing, studies, and experts’ advice.”

Grow Your Own

In the homes of the future, it will be possible to grow your own vegetables no matter the climate. Samsung recently showcased Chef Garden at KBIS 2019, an AI farming platform that integrates with the next generation of Family Hub. The smart indoor garden uses seed capsules, allowing people to grow small fruits, vegetables and herbs with only a small part of the plant. Chef Garden controls light, temperature and humidity to optimize plant growth. The system also utilizes fogponics technology, which creates a nutrient fog that delivers water and nutrients directly to the plants so that they can grow without the need for pesticides. With water kept to the minimum required, the inside of Chef Garden always remains clean. Chef Garden can also inform users when plants are ready to harvest and recommend recipes thanks to smart integration with Family Hub.

Fruitful Investments and Research

Samsung is supporting research and development in fields such as basic sciences, materials science and ICT through the Samsung Science and Technology Foundation. Samsung has funded 500 project grants for the Korean scientific community to explore since 2013, amongst which are technology research projects examining vertical farming and the acceleration of plant growth. In addition, it is expected that further discoveries garnered from ICT projects involving AI, IoT and LEDs will foster synergy between Samsung’s technology and industrial farming’s efforts to produce healthy food.

“One of the main objectives of this support project is to consider how technology might solve the environmental and food shortage problems society faces today,” said Doochan Daniel Eum, Head of the Samsung Research & Incubation Center for Future Technology. “It’s our intention to contribute a total of 1.5 trillion Korean Won (approximately 1.3 billion USD) by 2023, investing in technologies that can effect real change for future society.”

According to the United Nations, the world’s population is set to reach 9.8 billion by 2050. Such a large population would require approximately 1.7 times more food than is available now.

One potential solution for addressing the world’s need for more healthy and abundant food production is vertical farming – a process that’s growing increasingly popular in places like Europe, the U.S. and Japan, and involves food being grown indoors in vertically stacked layers.

Stable Food Production

What makes vertical farming such an efficient and viable means to produce food are the facts that it (1) saves space, and (2) allows farmers to grow crops all year round, regardless of climate or season.

Interest in vertical farming has been rapidly growing in recent years. Market research firm MarketsandMarkets predicts that the global market for vertical farming will be worth $18.4 billion by 2022, which is twice as much as the market was valued in 2016 ($9 billion).

Innovating for a Greener Future

The movement for healthy, sustainable food production is spreading across the world, and Samsung is committed to driving innovation in this area.

Last spring, Samsung announced the launch of a wide range of horticulture LED offerings that produce a broad spectrum of light to support healthy plant growth. On April 23, Samsung introduced an update to the LM301H, which features the highest photon efficacy among today’s mid-power white LED packages. The company has also revealed a number of exciting innovations designed to make it easy for consumers to grow and enjoy fresh, healthy vegetables from the comfort of their home.

Samsung also made waves at this year’s Kitchen & Bath Industry Show in Las Vegas with its all-new Chef Gardentechnology, which offers a simple, environmentally friendly way to grow food at home. Chef Garden integrates seamlessly with Samsung’s next-generation Family Hub refrigerator, and automatically regulates light wavelengths to enable users to grow and enjoy fresh, pesticide-free fruit and vegetables all year round.

“There is a growing interest in healthy food,” said Chohui Kim of Samsung Electronics’ LED Technology Center. “Horticulture LED is playing a key role in vertical farming and indoor crop cultivation, and we are looking to expand its applications in various fields.”

The second part of Samsung Electronics’ “Going Green” series will highlight technology trends and the company’s efforts regarding eco-friendly crop cultivation in detail.
