Environmentally friendly in the context of "Sustainable diet"

Reykjavík is the capital and largest city of Iceland. It is located on the southern shore of the Faxaflói bay in southwest Iceland and has a latitude of 64°08′ N, making it the world's northernmost capital of a sovereign state. Reykjavík has a population of around 139,000 as of 2025, and the surrounding Capital Region has a population of around 249,000, constituting approximately 64% of Iceland's population.

According to Landnámabók, the settlement of Iceland began in Reykjavík when Ingólfur Arnarson arrived from Norway in the year 874. For over 900 years following this, there was no urban development; the city was officially founded in 1786 as a trading town and grew steadily as it transformed into its current state as the centre of Iceland's cultural, economic, and governmental activity. It is popular with tourists and is consistently ranked as one of the cleanest, safest, and most environmentally friendly cities in the world.

Biomining refers to any process that uses living organisms to extract metals from ores and other solid materials. Typically these processes involve prokaryotes, however fungi and plants (phytoextraction also known as phytomining) may also be used. Biomining is one of several applications within biohydrometallurgy with applications in ore refinement, precious metal recovery, and bioremediation. The largest application currently being used is the treatment of mining waste containing iron, copper, zinc, and gold allowing for salvation of any discarded minerals. It may also be useful in maximizing the yields of increasingly low grade ore deposits. Biomining has been proposed as a relatively environmentally friendly alternative and/or supplementation to traditional mining. Current methods of biomining are modified leach mining processes. These aptly named bioleaching processes most commonly includes the inoculation of extracted rock with bacteria and acidic solution, with the leachate salvaged and processed for the metals of value. Biomining has many applications outside of metal recovery, most notably is bioremediation which has already been used to clean up coastlines after oil spills. There are also many promising future applications, like space biomining, fungal bioleaching and biomining with hybrid biomaterials.

NABERS, the National Australian Built Environment Rating System is an Australian national initiative, managed by the Government of New South Wales' Department of Climate Change, Energy, the Environment and Water (New South Wales) on behalf of the Australian Government, that measures and compares the environmental performance of Australian buildings and tenancies.

There are NABERS rating tools for commercial office buildings to measure greenhouse gas emissions, energy efficiency, water efficiency, waste efficiency and indoor environment quality. There are also energy/greenhouse and water rating tools for hotels, shopping centres and data centres.

Soy ink is a plant-based ink made from soybeans (Glycine max). Soy-based ink is environmentally friendly and provides precise colours. However, it is slower to dry than other organic inks.

The Heliotrope is an environmentally friendly housing project by German architect Rolf Disch. There are three such buildings in Germany. The first experimental version was built in 1994 as the architect's home in Freiburg im Breisgau, while the other two were used as exhibition buildings for the Hansgrohe company in Offenburg and a dentist's lab in Hilpoltstein in Bavaria.

Several different energy generation modules are used in the building including a 603 sq ft (56.0 m) dual-axis solar photovoltaic tracking panel, a geothermal heat exchanger, a combined heat and power unit (CHP) and solar-thermal balcony railings to provide heat and warm water. These innovations along with the favorable insulation of the residence allows the Heliotrope to capture anywhere between four and six times its energy usage depending on the time of year. The Heliotrope is also fitted with a grey-water cleansing system and built-in natural waste composting.

Bioremediation broadly refers to any process wherein a biological system (typically bacteria, microalgae, fungi in mycoremediation, and plants in phytoremediation), living or dead, is employed for removing environmental pollutants from air, water, soil, fuel gasses, industrial effluents etc., in natural or artificial settings. The natural ability of organisms to adsorb, accumulate, and degrade common and emerging pollutants has attracted the use of biological resources in treatment of contaminated environment. In comparison to conventional physicochemical treatment methods bioremediation may offer advantages as it aims to be sustainable, eco-friendly, cheap, and scalable.

Most bioremediation is inadvertent, involving native organisms. Research on bioremediation is heavily focused on stimulating the process by inoculation of a polluted site with organisms or supplying nutrients to promote their growth. Environmental remediation is an alternative to bioremediation.

León (Spanish pronunciation: [leˈon]), officially León de Los Aldama, is the most populous city and municipal seat of the municipality of León in the Mexican state of Guanajuato. In the 2020 census, INEGI reported 1,579,803 people living in the city of León and 1,721,215 in the municipality, making it the fourth-most populous city and third-most populous municipality in Mexico. The metropolitan area of León recorded a population of 2,140,094 in the 2020 state census, making it the seventh most populous metropolitan area in Mexico. León is part of the macroregion of Bajío within the Central Mexican Plateau.

León has a large leather industry, making shoes, boots, belts, jackets, and other leather accessories for national and international markets. The leather industry earned its inhabitants the nickname of "green belly" (panzaverde in Spanish) because of the green tainting in the workers' bodies resulting from treating leather. Its first-class services and hotel industry make it an important commercial center in Mexico with numerous options for entertainment, gastronomy, leisure activities, arts, and recreation. It is also considered one of the most environmentally friendly cities in Mexico and has a high number of cyclists, in part because of integrating a network of bike lanes into the SIT system. In March 2012, it received an award as "City Water Champion", mainly due to great progress in the areas of sanitation, wastewater reuse, and energy cogeneration from biogas.

Comcast Center, also known as the Comcast Tower, is a skyscraper at 1701 John F. Kennedy Boulevard in Center City, Philadelphia. The 58-story, 973-foot (297 m) tower is the second-tallest building in Philadelphia and in the U.S. Commonwealth of Pennsylvania, and the 31st-tallest building in the United States. Originally called One Pennsylvania Plaza when plans for the building were announced in 2001, the Comcast Center went through two redesigns before construction began in 2005. Comcast Center was designed by Robert A.M. Stern Architects for Liberty Property Trust.

In early 2005, the final redesign and its new name—the Comcast Center—were unveiled. The building is named after its lead tenant, cable company Comcast, which makes the skyscraper its corporate headquarters. Leasing 1,094,212 square feet (101,656 m), Comcast takes up 89 percent of the building. The building features retail and restaurant space and a connection to Suburban Station which is nearby. In Comcast Center's lobby is the Comcast Experience, which is a 2,000-square-foot (190 m) high-definition LED screen that has become a tourist attraction. Designed to be environmentally friendly, the skyscraper is the tallest Leadership in Energy and Environmental Design (LEED) certified building in Philadelphia.

Camel milk is milk from female camels. It has supported nomad and pastoral cultures since the domestication of camels millennia ago. Herders may for periods survive solely on the milk when taking the camels on long distances to graze in desert and arid environments, especially in parts of the Middle East, North Africa and the Horn of Africa. The camel dairy farming industry has grown in Australia and the United States, as an environmentally friendly alternative to cow dairy farming using a species well-adapted to arid regions.Camel milk has different nutritional characteristics from cow milk, but the proportions of nutrients can be highly variable based on a number of factors, including type and age of camel, climate, what it eats, and milking method. It can be used to make products such as yogurt and ice cream, but is not so easily turned into butter or cheese. Camel milk tastes similar to cow's milk.
