Aktuell besteht ein großes Interesse an nachhaltiger Ernährung. Kantinen, insbesondere jene in öffentlichen Einrichtungen, werden in Verantwortung gesehen, eine Vorreiterrolle zu übernehmen. Diese Broschüre will daher mit drei bereits bestehenden guten Beispielen aufzeigen, wie eine Transformation in Kantinen und Mensen gelingen kann. Sie richtet sich in erster Linie an die Verantwortlichen für das Verpflegungskonzept, die Rezept- und Speisenplanung und den Lebensmitteleinkauf. Darüber hinaus sind Personen, die sich mit Ausschreibungen für den Einkauf von Lebensmitteln oder die Verpflegungsdienstleistungen befassen angesprochen. Darin teilen die Praxispartner*innen Anregungen und Tipps, die anderen (Küchen-)Betrieben den Umstellungsprozess erleichtern sollen. Ergänzt werden diese drei Beispiele von themenspezifischen Handlungsempfehlungen, die im Rahmen des Forschungsprojekts erarbeitet wurden und Ansatzpunkte zur Optimierung der Verpflegungsleistung bieten.

technologyComment of gold mine operation and refining (SE): OPEN PIT MINING: The ore is mined in four steps: drilling, blasting, loading and hauling. In the case of a surface mine, a pattern of holes is drilled in the pit and filled with explosives. The explosives are detonated in order to break up the ground so large shovels or front-end loaders can load it into haul trucks. ORE AND WASTE HAULAGE: The haul trucks transport the ore to various areas for processing. The grade and type of ore determine the processing method used. Higher-grade ores are taken to a mill. Lower grade ores are taken to leach pads. Some ores may be stockpiled for later processing. HEAP LEACHING: The ore is crushed or placed directly on lined leach pads where a dilute cyanide solution is applied to the surface of the heap. The solution percolates down through the ore, where it leaches the gold and flows to a central collection location. The solution is recovered in this closed system. The pregnant leach solution is fed to electrowinning cells and undergoes the same steps as described below from Electro-winning. ORE PROCESSING: Milling: The ore is fed into a series of grinding mills where steel balls grind the ore to a fine slurry or powder. Oxidization and leaching: Some types of ore require further processing before gold is recovered. In this case, the slurry is pressure-oxidized in an autoclave before going to the leaching tanks or a dry powder is fed through a roaster in which it is oxidized using heat before being sent to the leaching tanks as a slurry. The slurry is thickened and runs through a series of leaching tanks. The gold in the slurry adheres to carbon in the tanks. Stripping: The carbon is then moved into a stripping vessel where the gold is removed from the carbon by pumping a hot caustic solution through the carbon. The carbon is later recycled. Electro-winning: The gold-bearing solution is pumped through electro-winning cells or through a zinc precipitation circuit where the gold is recovered from the solution. Smelting: The gold is then melted in a furnace at about 1’064°C and poured into moulds, creating doré bars. Doré bars are unrefined gold bullion bars containing between 60% and 95% gold.

In the case of a surface mine, a pattern of holes is drilled in the pit and filled with explosives. The explosives are detonated in order to break up the ground so large shovels or front-end loaders can load it into haul trucks. UNDERGROUND MINING: Some ore bodies are more economically mined underground. In this case, a tunnel called an adit or a shaft is dug into the earth. Sort tunnels leading from the adit or shaft, called stopes, are dug to access the ore. The surface containing the ore, called a face, is drilled and loaded with explosives. Following blasting, the broken ore is loaded onto electric trucks and taken to the surface. Once mining is completed in a particular stope, it is backfilled with a cement compound. BENEFICIATION: Bald Mountain Mines: The ore treatment method is based on conventional heap leaching technology followed by carbon absorption. The loaded carbon is stripped and refined in the newly commissioned refinery on site. Water is supplied by wells located on the mine property. Grid power was brought to Bald Mountain Mine in 1996. For this purpose, one 27-kilometre 69 KVA power line was constructed from the Alligator Ridge Mine substation to the grid. Golden Sunlight Mines: The ore treatment plant is based on conventional carbon-in-pulp technology, with the addition of a Sand Tailings Retreatment (STR) gold recovery plant to recover gold that would otherwise be lost to tailings. The STR circuit removes the heavier gold bearing pyrite from the sand portion of the tailings by gravity separation. The gold is refined into doré at the mine. Tailing from the mill is discharged to an impoundment area where the solids are allowed to settle so the water can be reused. A cyanide recovery/destruction process was commissioned in 1998. It eliminates the hazard posed to wildlife at the tailings impoundment by lowering cyanide concentrations below 20 mg/l. Fresh water for ore processing, dust suppression, and fire control is supplied from the Jefferson Slough, which is an old natural channel of the Jefferson River. Ore processing also uses water pumped from the tailings impoundment. Pit water is treated in a facility located in the mill complex prior to disposal or for use in dust control. Drinking water is made available by filtering fresh water through an on-site treatment plant. Electric power is provided from a substation at the south property boundary. North-Western Energy supplies electricity the substation. Small diesel generators are used for emergency lighting. A natural gas pipeline supplies gas for heating buildings, a crusher, air scrubber, boiler, carbon reactivation kiln, and refining furnaces. Cortez Mine: Three different metallurgical processes are employed for the recovery of gold. The process used for a particular ore is determined based on grade and metallurgical character of that ore. Lower grade oxide ore is heap leached, while higher-grade non-refractory ore is treated in a conventional mill using cyanidation and a carbon-in-leach (“CIL”) process. When carbonaceous ore is processed by Barrick, it is first dry ground, and then oxidized in a circulating fluid bed roaster, followed by CIL recovery. In 2002 a new leach pad and process plant was commissioned; this plant is capable of processing 164 million tonnes of heap leach ore over the life of the asset. Heap leach ore production is hauled directly to heap leach pads for gold recovery. Water for process use is supplied from the open pit dewatering system. Approximately 90 litres per second of the pit dewatering volume is diverted for plant use. Electric power is supplied by Sierra Pacific Power Company (“SPPC”) through a 73 kilometre, 120 kV transmission line. A long-term agreement is in place with SPPC to provide power through the regulated power system. The average power requirement of the mine is about 160 GWh/year. REFINING: Wohlwill electrolysis. It is assumed that the gold doré-bars from both mines undergo the treatment of Wohlwill electrolysis. This process uses an electrolyte containing 2.5 mol/l of HCl and 2 mol/l of HAuCl4 acid. Electrolysis is carried out with agitation at 65 – 75 °C. The raw gold is intro-duced as cast anode plates. The cathodes, on which the pure gold is deposited, were for many years made of fine gold of 0.25 mm thickness. These have now largely been replaced by sheet titanium or tantalum cathodes, from which the thick layer of fine gold can be peeled off. In a typical electrolysis cell, gold anodes weighing 12 kg and having dimensions 280×230×12 mm (0.138 m2 surface) are used. Opposite to them are conductively connected cathode plates, arranged by two or three on a support rail. One cell normally contains five or six cathode units and four or five anodes. The maximum cell voltage [V] is 1.5 V and the maximum anodic current density [A] 1500 A/m2. The South African Rand refinery gives a specific gold production rate of 0.2 kg per hour Wohlwill electrolysis. Assuming a current efficiency of 95% the energy consumption is [V] x [A] / 0.2 [kg/h] = 1.63 kWh per kg gold refined. No emissions are assumed because of the purity and the high value of the material processed. The resulting sludge contains the PGM present in the electric scrap and is sold for further processing.

The milling process consists of primary crushing, secondary crushing, rod/ball mill grinding, gravity concentration, cyanide leaching, carbon-in-pulp gold recovery, stripping, electrowinning and refining. In the Campbell Mine, the ore from the mine, after crushing and grinding, is processed by gravity separation, flotation, pressure oxidation, cyanidation and carbon-in-pulp process followed by electro-winning and gold refining to doré on site.

It also employs the world’s leading silver refining technology. To further refine gold and silver to 99.99% the cost-effective once-through Wohlwill electrolytic refining process is used. MILLER CHLORINATION PROCESS: This is a pyrometallurgical process whereby gold dore is heated in furnace crucibles. The process is able to separate gold from impurities by using chlorine gas which is added to the crucibles once the gold is molten. Chlorine gas does not react with gold but will combine with silver and base metals to form chlorides. Once the chlorides have formed they float to the surface as slag or escape as volatile gases. The surface melt and the fumes containing the impurities are collected and further refined to extract the gold and silver. This process can take up to 90 minutes produces gold which is at least 99.5% pure with silver being the main remaining component. This gold can be cast into bars as 99.5% gold purity meets the minimum London Good Delivery. However some customers such as jewellers and other industrial end users require gold that is almost 100% pure, so further refining is necessary. In this case, gold using the Miller process is cast into anodes which are then sent to an electrolytic plant. The final product is 99.99% pure gold sponge that can then be melted to produce various end products suited to the needs of the customer. WOHLWILL PROCESS - The electrolytic method of gold refining was first developed by Dr. Emil Wohlwill of Norddeutsche Affinerie in Hamburg in 1874. Dr. Wohlwill’s process is based on the solubility of gold but the insolubility of silver in an electrolyte solution of gold chloride (AuCl3) in hydrochloric acid.

WATER SUPPLY: For Misima Mine, process water is supplied from pit dewatering bores and in-pit water. Potable water is sourced from boreholes in the coastal limestone. For Porgera Mine, the main water supply of the mine is the Waile Creek Dam, located approximately 7 kilometres from the mine. The reservoir has a capacity of approximately 717, 000 m3 of water. Water for the grinding circuit is also extracted from Kogai Creek, which is located adjacent to the grinding circuit. The mine operates four water treatment plants for potable water and five sewage treatment plants. ENERGY SUPPLY: For Misima Mine, electricity is produced by the mine on site or with own power generators, from diesel and heavy fuel oil. For Porgera Mine, electricity is produced by the mine on site. Assumed with Mobius / Wohlwill electrolysis. Porgera's principal source of power is supplied by a 73-kilometre transmission line from the gas fired and PJV-owned Hides Power Station. The station has a total output of 62 megawatts (“MW”). A back up diesel power station is located at the mine and has an output of 13MW. The average power requirement of the mine is about 60 MW. For both Misima and Porgera Mines, an 18 MW diesel fired power station supplies electrical power. Diesel was used in the station due to the unavailability of previously supplied heavy fuel oil. technologyComment of gold-silver mine operation with refinery (CA-QC): One of the modelled mine is an open-pit mine and the two others are underground. technologyComment of gold-silver mine operation with refinery (RoW): The mining of ore from open pit mines is considered. technologyComment of platinum group metal, extraction and refinery operations (ZA): The ores from the different ore bodies are processed in concentrators where a PGM concentrate is produced with a tailing by product. The PGM base metal concentrate product from the different concentrators processing the different ores are blended during the smelting phase to balance the sulphur content in the final matte product. Smelter operators also carry out toll smelting from third part concentrators. The smelter product is send to the Base metal refinery where the PGMs are separated from the Base Metals. Precious metal refinery is carried out on PGM concentrate from the Base metal refinery to split the PGMs into individual metal products.

Mudd, G., 2010. Platinum group metals: a unique case study in the sustainability of mineral resources, in: The 4th International Platinum Conference, Platinum in Transition “Boom or Bust.” technologyComment of primary zinc production from concentrate (RoW): The technological representativeness of this dataset is considered to be high as smelting methods for zinc are consistent in all regions. Refined zinc produced pyro-metallurgically represents less than 5% of global zinc production and less than 2% of this dataset. Electrometallurgical Smelting The main unit processes for electrometallurgical zinc smelting are roasting, leaching, purification, electrolysis, and melting. In both electrometallurgical and pyro-metallurgical zinc production routes, the first step is to remove the sulfur from the concentrate. Roasting or sintering achieves this. The concentrate is heated in a furnace with operating temperature above 900 °C (exothermic, autogenous process) to convert the zinc sulfide to calcine (zinc oxide). Simultaneously, sulfur reacts with oxygen to produce sulfur dioxide, which is subsequently converted to sulfuric acid in acid plants, usually located with zinc-smelting facilities. During the leaching process, the calcine is dissolved in dilute sulfuric acid solution (re-circulated back from the electrolysis cells) to produce aqueous zinc sulfate solution. The iron impurities dissolve as well and are precipitated out as jarosite or goethite in the presence of calcine and possibly ammonia. Jarosite and goethite are usually disposed of in tailing ponds. Adding zinc dust to the zinc sulfate solution facilitates purification. The purification of leachate leads to precipitation of cadmium, copper, and cobalt as metals. In electrolysis, the purified solution is electrolyzed between lead alloy anodes and aluminum cathodes. The high-purity zinc deposited on aluminum cathodes is stripped off, dried, melted, and cast into SHG zinc ingots (99.99 % zinc). Pyro-metallurgical Smelting The pyro-metallurgical smelting process is based on the reduction of zinc and lead oxides into metal with carbon in an imperial smelting furnace. The sinter, along with pre-heated coke, is charged from the top of the furnace and injected from below with pre-heated air. This ensures that temperature in the center of the furnace remains in the range of 1000-1500 °C. The coke is converted to carbon monoxide, and zinc and lead oxides are reduced to metallic zinc and lead. The liquid lead bullion is collected at the bottom of the furnace along with other metal impurities (copper, silver, and gold). Zinc in vapor form is collected from the top of the furnace along with other gases. Zinc vapor is then condensed into liquid zinc. The lead and cadmium impurities in zinc bullion are removed through a distillation process. The imperial smelting process is an energy-intensive process and produces zinc of lower purity than the electrometallurgical process. technologyComment of processing of anode slime from electrorefining of copper, anode (GLO): Based on typical current technology. Anode slime treatment by pressure leaching and top blown rotary converter. Production of Silver by Möbius Electrolysis, Gold by Wohlwill electrolysis, copper telluride cement and crude selenium to further processing. technologyComment of silver-gold mine operation with refinery (CL): OPEN PIT MINING: The ore is mined in four steps: drilling, blasting, loading and hauling. In the case of a surface mine, a pattern of holes is drilled in the pit and filled with explosives. The explosives are detonated in order to break up the ground so large shovels or front-end loaders can load it into haul trucks. BENEFICIATION: The processing plant consists of primary crushing, a pre-crushing circuit, (semi autogenous ball mill crushing) grinding, leaching, filtering and washing, Merrill-Crowe plant and doré refinery. The Merrill-Crowe metal recovery circuit is better than a carbon-in-pulp system for the high-grade silver material. Tailings are filtered to recover excess water as well as residual cyanide and metals. A dry tailings disposal system was preferred to a conventional wet tailings impoundment because of site-specific environmental considerations. technologyComment of silver-gold mine operation with refinery (RoW): Refinement is estimated with electrolysis-data. technologyComment of treatment of precious metal from electronics scrap, in anode slime, precious metal extraction (SE, RoW): Anode slime treatment by pressure leaching and top blown rotary converter.

Im vorliegenden Gutachten sind die drei Warenströme von Fleisch und Fleischprodukten, Milch und Milchprodukten, sowie Eier und Eiprodukten in Deutschland dargestellt. Die dazu verfügbaren Daten wurden mit Hilfe einer systematischen Recherche nach Art eines Scoping Reviews zusammengetragen. Die Warenströme wurden weitestgehend aus den Wertschöpfungsketten abgeleitet, sie betrachten sowohl die Mengen an tierischen Lebensmitteln als auch die dafür gehaltenen Anzahlen von Tieren. Die Warenströme umfassen die Stufen Primärproduktion, Agrarhandel, Verarbeitung, Verfügbar zum Verbrauch, Verzehrbar, Vermarktung (Großhandel, Einzelhandel, Außer-Haus-Verpflegung) und Verbrauch einschließlich des Verzehrs. Zur Darstellung der Warenströme über Zahlen in Tabellen und visuell in Sankey-Plots wurden die Mengenangaben auf einheitliche Bezugsmaße z.B. Nutzungsgrade des Ausgangsproduktes und pro-Kopf-und-Jahr-Angaben umgerechnet. Im Vergleich zu aktuellen Mengen und Tierzahlen wurden die potenziellen Auswirkungen eines Verzehrs nach den Empfehlungen der Planet Health Diet auf die Warenströme abgeschätzt.

Die Vorhabenträgerin hat das Projekt CCM innerhalb ihrer Regelzone in sechs Planfeststellungsabschnitte unterteilt. Gegenstand dieses Planfeststellungsverfahrens ist der Abschnitt 3. Für das Neubau- und Rückbauvorhaben im Planfeststellungsabschnitt 3 werden Grundstücke in den Gemeinden Cappeln (Oldenburg) (Gemarkung Cappeln), Emstek (Gemarkung Emstek), Garrel (Gemarkung Garrel) sowie in der Stadt Cloppenburg (Gemarkung Cloppenburg) beansprucht. Für die Wegenutzung werden Grundstücke in den Gemeinden Cappeln (Oldenburg) (Gemarkung Cappeln), Emstek (Gemarkung Emstek), Garrel (Gemarkung Garrel), Großenkneten (Gemarkung Großenkneten), Lastrup (Gemarkung Lastrup) sowie in der Stadt Cloppenburg (Gemarkung Cloppenburg) beansprucht. Die Gemeinden Cappeln (Oldenburg) (Gemarkung Cappeln), Emstek (Gemarkung Emstek), Essen (Oldenburg) (Gemarkung Essen (Oldenburg)), Großenkneten (Gemarkung Großenkneten) sowie die Stadt Friesoythe (Gemarkung Altenhoythe) sind durch Kompensationsflächen, die zum Teil auch außerhalb des Trassenbereichs liegen, betroffen. Der Abschnitt 3 beginnt am neu zu errichtendem UW Garrel Ost, endet am neu zu errichtendem UW Cappeln West und umfasst ca. 25 km. Dieser Abschnitt beinhaltet den Neubau der 380-kV-Leitung (LH-14-325) zwischen den beiden UW Garrel Ost und Cappeln West, den Rückbau der 220-kV-Bestandsleitung (LH-14-206) von Mast 125 bis zum Portal im UW Cloppenburg Ost, die Mitnahme der 110-kV-Leitung (LH-14-143) des Verteilnetzbetreibers Avacon zwischen dem neuen UW Garrel Ost und dem bestehenden UW Cloppenburg Ost inkl. der Ein- und Ausschleifung der Leitung sowie die Ein- und Ausschleifung der 110-kV-Bestandsleitung (LH-14-114) in das neue UW Cappeln West zwischen den Masten 9 und 12 inkl. dem Rückbau von zwei Bestandsmasten, wodurch die Leitungen LH-14-144 und LH-14-114 neu entstehen. Weitere Gegenstände sind die Provisorien für die 220-kV-Bestandsleitung, die 110-kV Provisorien im Nahbereich des UW Cappeln West sowie die außerhalb des Trassenbereichs lie-genden Kompensationsflächen. Die Neubauleitung beginnt am Anschlussportal an der Ostflanke des UW Garrel Ost (Gemeinde Garrel). Die Leitung verläuft in südlicher Richtung, wo an Mast 3 die Mitnahme der 110-kV-Leitung (LH-14-143) beginnt. Diese wird an der Westseite des UW Garrel Ost am 110-kV Anschlussportal angeschlossen und mittels zweier Maste zum ersten gemeinsamen Mast 3 geführt. Die Leitung kreuzt die Tweeler Straße westlich der Vehne und verläuft auf gerader Strecke in Richtung Süden westlich der 220-kV-Bestandsleitung (LH-14-206). Zwischen den Neubaumasten 22 und 23 bzw. 23V werden die 220-kV-Bestandsleitung und die bestehende 110-kV-Leitung (LH-14-056) gekreuzt. Zur Realisierung der Kreuzung ist die Errichtung von Leitungsprovisorien vorgesehen. Die Leitung verläuft weiter in südöstlicher Richtung und kreuzt die B213 (Ahlhorner Straße) im Bereich Bethen. Am Mast 28 wird die 110-kV-Leitung (LH-14-143) aus der gemeinsamen Trasse ausgeschleift und auf eigenem Gestänge durch Neuerrichtung dreier 110-kV-Maste in das bestehende UW Cloppenburg Ost geführt. Die 380-kV-Neubauleitung kreuzt im weiteren Verlauf die Bahnstrecke 1502 Oldenburg – Osnabrück und verläuft in östliche Richtung parallel nördlich zur B72 (E233) bis ca. auf Höhe der bestehenden PWC-Anlage innerhalb der Gemeinde Emstek. Westlich des Parkplatzes wird die B72 gekreuzt, woraufhin die Leitung in südliche Richtung weiterverläuft und zwischen den Masten 36 und 38 ein geplantes Gewerbegebiet quert. Die Leitung verläuft weiter in westliche Richtung, knickt am Mast 44 in südliche Richtung und am Mast 46 in östliche Richtung ab. Anschließend kreuzt die Leitung die K171 (Cappelner Straße) und knickt am Mast 49 in Richtung Westen ab. Ab Mast 56 verläuft die Leitung in nordwestliche Richtung, knickt an Mast 59 in Richtung Westen und verläuft geradlinig nördlich der Gasfackelanlage Kneheim an das Portal des UW Cappeln West. Westlich des UW Cappeln West verläuft von Nord nach Süd die 110-kV-Bestandsleitung (LH-14-114). Diese wird zwischen den Masten 9 und 12 ein- bzw. ausgeschleift, wodurch die Leitungen LH-14-144 und LH-14-114 neu entstehen. Zur Realisierung der Ein- bzw. Ausschleifung wird ein Provisorium benötigt, das östlich um das neue UW führt. Der Planfeststellungsabschnitt 3 endet am neu zu errichtendem UW Cappeln West. Zusammen mit dem Antrag auf Planfeststellung beabsichtigt die Vorhabenträgerin die Erteilung der gehobenen wasserrechtlichen Erlaubnis nach §§ 8, 9, 10 und 15 WHG für die temporäre Grundwasserentnahme aus dem Neubau sowie zur Einleitung des geförderten Grundwassers in verschiedene oberirdische Gewässer (Bäche und Gräben) und in das Grundwasser durch Wiederversickerung / Verrieselung zu beantragen. Erforderliche wasserrechtliche Erlaubnisse und Bewilligungen können im Zuge des Planfeststellungsverfahrens von der Planfeststellungsbehörde gesondert im Einvernehmen mit der örtlich zuständigen Unteren Wasserbehörde erteilt werden. Auf Grundlage der Baugrundvoruntersuchung ist von der Vorhabenträgerin ein Wasserhaltungskonzept zur Vordimensionierung der benötigten Wasserhaltung inklusive der Identifikation geeigneter Einleitstellen erstellt worden. Ebenfalls werden ver-schiedene Ausführungsmöglichkeiten an den entsprechenden Stellen in den Planfeststellungsunterlagen in Grundzügen dargelegt, um die Möglichkeit der wasserrechtlichen Konfliktbewältigung im Wege der Planfeststellung darzustellen. Das Wasserhaltungskonzept ist Bestandteil des Antrages auf Planfeststellung.
