Østfold ( Norwegian pronunciation: [ˈœ̂stfɔɫ] ) is a county in Eastern Norway , which from 1 January 2020 to 31 December 2023 was part of Viken . Østfold borders Akershus and southwestern Sweden ( Västra Götaland County and Värmland ), while Buskerud and Vestfold are on the other side of Oslofjord . The county's administrative seat is Sarpsborg . The county controversially became part of the newly established Viken County on 1 January 2020. On 1 January 2024, Østfold was re-established as an independent county, however without the former municipality of Rømskog, which was amalgamated with the Akershus municipality Aurskog-Høland in 2020.
55-523: Many manufacturing facilities are situated here, such as the world's most advanced biorefinery , Borregaard in Sarpsborg . Fredrikstad has shipyards. There are granite mines in Østfold and stone from these were used by Gustav Vigeland . The county slogan is "The heartland of Scandinavia". The local dialects are characterized by their geographical proximity to Sweden. The old name of the Oslofjord

Aimed at covering general medical needs of Østfold County and [Vestby Municipality] Østfold Hospital provides medical services, diagnostics, treatment and rehabilitation to
385-450: Is also referred to as a "cascading phase". The use of biomass as feedstock can provide a benefit by reducing the impacts on the environment, as lower pollutants emissions and reduction in the emissions of hazard products. In addition, biorefineries are intended to achieve the following goals: Biorefineries can be classified based in four main features: The aforementioned features are used to classified biorefineries systems according to
440-400: Is due to Rayleigh scattering by air molecules and particles much smaller than the wavelength of visible light (less than 50 nm in diameter). The scattering by cloud droplets and other particles with diameters comparable to or larger than the sunlight's wavelengths (more than 600 nm) is due to Mie scattering and is not strongly wavelength-dependent. Mie scattering is responsible for
495-427: Is hydrolyzed and fermented to produce ethanol, while the resulting liquor containing dissolved lignin is gasified and refined to dimethyl ether; the process demonstrate to be self-sufficient in terms of hot utility (fresh steam) demand but with a deficit of electricity; the process can be feasible, economically speaking, but is highly dependent on the development of biofuel prices. The exergetic and economic evaluation for
550-401: Is instead lofted into the stratosphere (as thin clouds of tiny sulfuric acid droplets), can yield beautiful post-sunset colors called afterglows and pre-sunrise glows. A number of eruptions, including those of Mount Pinatubo in 1991 and Krakatoa in 1883 , have produced sufficiently high stratospheric sulfuric acid clouds to yield remarkable sunset afterglows (and pre-sunrise glows) around
605-954: Is located in Alberta. The biorefinery utilizes Source Separated Organics from the metro Edmonton region, open pen feedlot manure , and food processing waste.

The main highway E6 between Oslo and Gothenburg runs as a motorway through the county from the southern border with Sweden and the border with Akershus county. The main highway E18 between Oslo and Stockholm goes through the county from the Swedish border in a southeast-northwest direction. The railway from Oslo to Gothenburg runs roughly parallel with E6, and there
715-418: Is obtained by dark fermentation of food waste with separation and purification of acetic and butyric acids (47 USD/t of food waste). The technical feasibility, profitability and extent of investment risk to produce sugar syrups from food and beverage waste was analyzed; the returns on investment shown to be satisfactory for the production of fructose syrup (9.4%), HFS42 (22.8%) and glucose-rich syrup (58.9%);
770-1108: Is one of the main sources of environmental impacts in the biofuel production, the source of this impacts are related to the field operation to grow, handle and transport the biomass to the biorefinery gate. Agricultural residues are the feedstock with the lowest environmental impact followed by lignocellulosic crops; and finally by first-generation arable crops, although the environmental impacts are sensitive to factors such as crop management practices, harvesting systems, and crop yields. The production of chemicals from biomass feedstock has shown environmental benefits; bulk chemicals from biomass-derived feedstocks have been studied showing savings on non renewable energy use and greenhouse gas emissions. The environmental assessment for 1G and 2G ethanol shows that these two biorefinery systems are able to mitigate climate change impacts in comparison to gasoline, but higher climate change benefits are achieved with 2G ethanol production (up to 80% reduction). The conversion of palm empty fruit bunches into valuable products (ethanol, heat and power, and cattle feed) reduces
825-408: Is produced by anaerobic fermentation of Jatropha fruit cake and seedcake; the second scenario includes the production of lipids from Jatropha and microalgae to produce biodiesel and the production of animal feed, biogas and organic fertilizer; the third scenario involves the production of lipids from microalgae for the production of biodiesel as well as hydrogen and animal feed as final product; only

Biteback Insect makes insect cooking oil, insect butter, fatty alcohols, insect frass protein and chitin from superworm ( Zophobas morio ). Sunrise Sunrise (or sunup ) is the moment when the upper rim of the Sun appears on
935-579: Is used to derive the time of sunrise and sunset, uses the Sun's physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc. Neglecting the effects of refraction and the Sun's non-zero size, whenever sunrise occurs, in temperate regions it is always in the northeast quadrant from the March equinox to the September equinox and in the southeast quadrant from
990-514: The axial tilt of Earth, daily rotation of the Earth, the planet's movement in its annual elliptical orbit around the Sun , and the Earth and Moon's paired revolutions around each other . The analemma can be used to make approximate predictions of the time of sunrise. In late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time shortly before
1045-416: The geocentric model , which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century. Architect Buckminster Fuller proposed the terms "sunsight" and "sunclipse" to better represent the heliocentric model, though the terms have not entered into common language. Astronomically, sunrise occurs for only an instant, namely the moment at which the upper limb of
1100-458: The horizon in the morning , at the start of the Sun path . The term can also refer to the entire process of the solar disk crossing the horizon. Although the Sun appears to "rise" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame ; this apparent motion caused many cultures to have mythologies and religions built around
1155-423: The kraft process for producing bioethanol from softwoods in a repurposed or co-located kraft mill has been studied, a sugar recovery higher than 60% enables the process to be competitive for the production of ethanol from softwood. The repurposing of a kraft pulp mill to produce both ethanol and dimethyl ether has been investigated; in the process, cellulose is separated by and an alkaline pretreatment and then

#17327878501351210-429: The summer solstice ; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest shortly after the winter solstice , also varying by latitude. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict
1265-513: The IRR of the base case (10.3%). Likewise, the production of ethanol, lactic acid or methanol and ethanol-lactic acid from sugarcane bagasse have been studied; lactic acid demonstrated to be economically attractive by showing the greatest net present value (M$ 476–1278); in the same way; the production of ethanol and lactic acid as co-product was found to be a favorable scenario (net present value between M$ 165 and M$ 718) since this acid has applications in
1320-579: The September equinox to the March equinox. Sunrises occur approximately due east on the March and September equinoxes for all viewers on Earth. Exact calculations of the azimuths of sunrise on other dates are complex, but they can be estimated with reasonable accuracy by using the analemma . The figure on the right is calculated using the solar geometry routine in Ref. as follows: An interesting feature in
1375-496: The Sun appears tangent to the horizon. However, the term sunrise commonly refers to periods of time both before and after this point: The stage of sunrise known as false sunrise actually occurs before the Sun truly reaches the horizon because Earth's atmosphere refracts the Sun's image. At the horizon, the average amount of refraction is 34 arcminutes , though this amount varies based on atmospheric conditions. Also, unlike most other solar measurements, sunrise occurs when
1430-455: The Sun's upper limb , rather than its center, appears to cross the horizon. The apparent radius of the Sun at the horizon is 16 arcminutes. These two angles combine to define sunrise to occur when the Sun's center is 50 arcminutes below the horizon, or 90.83° from the zenith . The timing of sunrise varies throughout the year and is also affected by the viewer's latitude and longitude , altitude , and time zone . These changes are driven by
1485-416: The beam. At sunrise and sunset, when the path through the atmosphere is longer, the blue and green components are removed almost completely, leaving the longer-wavelength orange and red hues seen at those times. The remaining reddened sunlight can then be scattered by cloud droplets and other relatively large particles to light up the horizon red and orange. The removal of the shorter wavelengths of light
1540-507: The biorefinery concept can be implemented since sugarcane bagasse is a feasible feedstock to produce fuels and chemicals; lignocellulosic bioethanol (2G) is produced in Brazil in two plants with capacities of 40 and 84 Ml/y (about 0.4% of the production capacity in Brazil). TEA of ethanol production using mild liquefaction of bagasse plus simultaneous saccharification and co-fermentation shows
1595-410: The biorefinery concept is a promissory alternative since is possible to obtain biogas and other co-products including ethanol, xylitol, syngas, and electricity; this process also provides high profitability for high production scales.

The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)". As refineries, biorefineries can provide multiple chemicals by fractioning an initial raw material (biomass) into multiple intermediates (carbohydrates, proteins, triglycerides) that can be further converted into value-added products. Each refining phase
1815-440: The dates. Variations in atmospheric refraction can alter the time of sunrise by changing its apparent position. Near the poles, the time-of-day variation is extreme, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly. Accounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night . The sunrise equation , however, which
1870-491: The environment with pesticides, or higher energy and material demand that lead to environmental burdens. Life cycle assessment (LCA) is a methodology to evaluate the environmental load of a process, from the extraction of raw materials to the end use. LCA can be used to investigate the potential benefits of biorefinery systems; multiple LCA studies has been developed to analyse whether biorefineries are more environmentally friendly compared to conventional alternatives. Feedstock
1925-403: The figure on the right is apparent hemispheric symmetry in regions where daily sunrise and sunset actually occur. This symmetry becomes clear if the hemispheric relation in to the sunrise equation is applied to the x- and y-components of the solar vector presented in Ref. Air molecules and airborne particles scatter white sunlight as it passes through the Earth's atmosphere. This is done by
1980-539: The first scenario was profitable. In regard to the pulp and paper industry; lignin is a natural polymer co-generated and is generally used as boiler fuel to generate heat or steam to cover the energy demand in the process. Since lignin accounts for 10–30 wt% of the available lignocellulosic biomass and is equivalent to ~40% of its energy contents; the economics of biorefineries depend on the cost-effective processes to transform lignin into value-added fuels and chemicals. The conversion of an existing Swedish kraft pulp mill to

#17327878501352860-635: Was Fold ; Østfold means 'the region east of the Fold' (see also Vestfold ). The name was first recorded in 1543; in the Middle Ages the name of the county was Borgarsysla 'the county/sýsla of the city Borg (now Sarpsborg )'. Later, when Norway was under Danish rule , the Danish king divided the area into many baronies. These were merged into one county ( amt ) in 1662 - and it was then named Smaalenenes Amt 'the amt consisting of small len '. The name
