Sony developed the HDW-F900, the world's first digital video camera for cinema production, back in the year 2000. Then, in 2007, Sony released 4K digital cinema projection systems featuring Sony SXRD projectors. These products helped usher in the era of energy- and resource-saving digital cinema, replacing traditional film, which uses water and chemicals for film manufacturing and processing. In addition to conserving resources, digital film distribution to theaters is simplified using hard disks, which is much more efficient than transporting cases of traditional film. In 2013, Sony released the PMW-F55 CineAlta 4K camera, which supports 4K capturing in a compact package that consumes even less power.
Corporate meetings that require employees to travel from other locations generate CO2 emissions. The more meetings are held, the more transportation-driven emissions there are. To address this, Sony supplies video conferencing systems to help reduce CO2 emissions associated with employee travel. Sony is improving various aspects of the video conferencing experience, including image and audio quality, while increasing the number of locations that can join a single conference. The goal is to deliver a realistic conferencing experience that enables corporations to adopt video conferencing and reduce employee travel.
Sony has been offering Digital Paper devices since 2013, featuring displays that use original Sony technology to render fine text so that it appears as sharp and readable as printed text. These devices ship with a stylus that enables users to take notes just as easily and smoothly as when using real paper. Major paper users such as universities, offices and hospitals are adopting this digital paper technology to go paperless and conserve resources.
Sony Triporous™ is a plant-based porous carbon material with excellent adsorption qualities. Sony obtained an end-to-end patent on this material and began licensing Triporous™ to other companies starting in 2019. Made from rice husks, Triporous™ has a unique microstructure that enables easy adsorption of substances with large molecular weights, which conventional activated charcoal does not easily adsorb. These substances include humic substances and toxic cyanobacteria bloom, both organic substances that cause water pollution, as well as viruses and allergens. The properties of Triporous™ can be leveraged to develop high-performance environmental cleaning filters that remove pollutants in water and air, and it promises to have applications for plant wastewater treatment facilities and water purification systems in developing countries. Japan alone generates around two million tons a year of rice husks, from which Triporous™ is made, with more than 100 million tons generated worldwide each year. Recycling this surplus biomass to make Triporous™ contributes to the realization of a more environmental conscious, recycling-oriented society.
Sony commenced external sales of its proprietary Sustainable Oriented Recycled Plastic (SORPLAS™) in 2014. SORPLAS™ is a flame-retardant recycled plastic that offers excellent heat resistance, durability, and recyclability. It contains up to 99% recycled materials. SORPLAS™ was first used in Sony products in 2011 and has since been incorporated into a wide variety of Sony products. By now offering SORPLAS™ to other companies, Sony aims to promote the recycling of resources and help reduce the environmental impact of society as a whole. Many companies are interested in using SORPLAS™. It is already being used in a wide variety of products, including televisions, smartphones, lighting fixtures, and office supplies.
Sony's smart card passenger ticketing system, based on FeliCa™ contactless IC card technology, is helping to alleviate air pollution in Bangladesh. The city is facing serious air pollution issues due to increasing traffic congestion. The national bus company decided to adopt a FeliCa™ smart card passenger ticketing system in order to encourage the residents of Bangladesh to use municipal buses. The FeliCa™-based system has made it easier for users to get on and off buses. This added convenience has attracted more riders, which is in turn helping to alleviate traffic congestion.
The Sony Group company, Aerosense Inc., supplies industrial solutions integrating drone technology with cloud services. The company supports local governments and corporations with their environmental projects and operations. In Minamisoma-shi in Fukushima Prefecture, where decontamination work is being done on radioactive substances released into the environment when the Fukushima Daiichi Nuclear Power Plant was damaged in the Great East Japan Earthquake, since May 2016, Aerosense drones have been regularly monitoring a temporary storage facility that holds removed decontaminated substances. The drones inspect for ageing and/or deterioration of the outer surface of the sheet covering these substances at the facility. Since September 2016, Aerosense has also been involved in a project tackling pine wilt disease in protected coastal forests, which is a serious problem across Japan. The Aerosense drones use their cameras to identify damaged trees precisely. This technology is helping to establish new methods of maintaining and managing protected coastal forests.
