For easier understanding we have listed expressions in categories and explained them.
Old films are waste materials containing photographic chemicals and silver. During the recycling of films, substances such as paper, foil, synthetics and other materials are removed and the raw materials recycled.
Dentists, orthodontists and oral surgeons use highly sensitive dental films to take detailed images of the mouth and teeth. Due to their high sensitivity these x-ray films deliver a strong contrast and high image quality.
Duplicating films are used to produce x-ray copies.
There are two different types of laser films according to their sensitivity in the spectral range: helium neon laser films and infrared laser films. They mostly consist of a bluish polyester basis. On the backside an anti-halation layer absorbs the remaining light and increases the image sharpness.
Mammography films are special x-ray films which feature high resolution and gradation. They are used either layered on one side or layered on both sides. The one layered film achieves a higher resolution than the film layered on both sides.
Monitor films are green-sensitive x-ray films which respond to special fluorescent substances of various fluorescent screens. These films have a one-side emulsion layer. Instead of a second layer they have a gelatinous back coating.
During reproduction a repro film is produced as printed film material after a certain master. This process is used during pre-printing stage. During the recycling process materials such as silver and synthetics are separated and returned to the industrial cycle.
The x-ray film is an optimized photographic film. Due to its layers on both sides with a photographic emulsion, a better absorption of radiation is achieved. Therefore this film can be lit by x-rays. All types of x-ray films contain recyclable elements, such as silver and recyclable synthetics.
Computer tomography is a procedure for medical examination. A tube rotates around the patient and x-rays are used to radiograph the body’s tissue. Unlike the classic x-ray, three-dimensional images are created. This method is especially apt for examination of the bones.
Magnetic resonance imaging is a medical diagnostic procedure used to closely examine organs and tissue. Unlike CT scans or traditional X-rays, MRI uses no ionizing radiation.
X-ray is a classic imaging procedure used both in the medical and industrial sectors. With an x-ray examination, foreign particles, fissures in bones or tumors can be detected. Industrial companies use it for testing material strength and stability. The images are visible on x-ray films.
During recycling, x-ray films are initially ground and subsequently washed with enzymes to remove the image carrying layer and to recycle the silver. Additionally recyclable synthetics are gained. These materials can be returned to the economic cycle. Safe destruction of the images is guaranteed.
Chemical combinations of the element silver with halogens are called silver halides. Silver is one of the few elements – apart from lead or mercury – which in combination with halogens creates these insoluble salts. Silver fluoride (AgF), silver chloride (AgCl), silver bromide (AgBr) and siver iodide (AgI) are silver halides.
BREGAU integrates modern environmental protections and work security in industrial procedures. It has five professional teams with varied backgrounds and expertise concerning the subjects of management systems, work security, emission control, soil and ground water, coating technology, as well as certification and verification. One of the five expert teams is called BREGAU ZERT. It is a licensed environmental audit organization which certifies and controls waste disposal companies. Apart from that, the BREGAU ZERT certifies management systems concerning quality management and verifies environmental statements and emissions reports.
Together with other legal directives (like German Data Protection Laws of the Federal States, German Telemedia Act) the Federal Data Protection Law (BDSG) regulates the handling of personal data by official and private institutions and contains guidelines concerning collection, administration and “safe” handling of data.
The BImSchG (Federal Immissions Act) is part of the environmental law. It regulates the protection of the environment from the effects of air pollution, noise, tremors and similar occurrences.
The KrW-/AbfG (Closed Substance Cycle Waste Management Act) is a law created to nurture the economic cycle and assure environmentally sound waste disposal.
Waste disposal companies certified by the Closed Substance Cycle Waste Management Act (KrW-/AbfG) have specialized skills and equipment. Regular audits by special experts prove their reliability.
The German Federal Task Force for Waste (Bund/Länder-Arbeitsgemeinschaft Abfall - LAGA) is an advisory body of the Conference of the Environmental Ministers (Umweltministerkonferenz - UMK). This institution controls the uniform implementation of the waste law in all German Federal States. It establishes contacts between different interest groups and offers a platform for the exchange of information.
The verification procedure consists of a disposal document, consignment and delivery note, as well as an index. The verification procedure documents every step of the waste recycling process from its collection to final disposal. The verification procedure is only adapted for hazardous waste.
The GVZ (Güterverkehrszentrum) Bremen is a handling plant for containers with direct connection to ships and trains. It has an area of 360 hectares and houses 130 companies. According to a current ranking by the Deutsche Verkehrszeitung (DVZ, No. 601/2010) the GVZ Bremen holds the first position among 34 national cargo terminals, judged by structure and logistics.
