Scrap metal

To produce glass bottles, the mixture is prepared ia unit batches. Mixing is critical because complete homogeneity of the batch is necessary to produce quaUty glass. Gullet is added to the batch, usuady at discharge from the mixer. The cudet must be of the same color and basic composition, and be free of contamination such as metal bottie caps and tramp metal scraps.

Tractor-trailer systems. The apphcation of trac tor trailers is similar to that for tilt-frame-container systems. The use of a separate trac tor increases the number of axles and the net weight of waste that can be hauled. Tractor trailers are better for the collection of especially heavy rubbish, such as sand, timber, and metal scrap, and they are often are used for the collection of demolition wastes at construction sites.

An overview is presented of plutonium process chemistry at Rocky Flats and of research in progress to improve plutonium processing operations or to develop new processes. Both pyrochemical and aqueous methods are used to process plutonium metal scrap, oxide, and other residues. The pyrochemical processes currently in production include electrorefining, fluorination, hydriding, molten salt extraction, calcination, and reduction operations. Aqueous processing and waste treatment methods involve nitric acid dissolution, ion exchange, solvent extraction, and precipitation techniques. 

All actinide metals are pyrophoric and it is common practice to burn metallic scrap to oxide as a safety precaution. 

The advantage of hydride recovery is its ability to recover a large fraction of the scrap in metallic form. This method therefore has a major economic advantage over chemical recycle and subsequent reduction to metal. It is just beginning to be used as a production aid for metallic scrap recovery. 

Scrap metal Scrap metal that is disposed of or recycled is a solid waste however, it is exempt from Subtitle C regulation when it is reclaimed (i.e., recycled to recover metal content). This does not apply to processed scrap metal that is excluded from hazardous waste regulation entirely. 

Processed scrap metal. Scrap metal includes, but is not limited to, pipes, containers, equipment, wire, and other metal items that are no longer of use. To facilitate recycling, scrap metal that has been processed to make it easier to handle or transport and is sent for metals recovery is excluded from the definition of solid waste. Unprocessed scrap metal is still eligible for an exemption from hazardous waste regulation when recycled. 

The Commission is working on establishing end-of-waste criteria for a number of specific recyclable materials including metal scrap of copper, aluminum and iron, waste paper, waste glass, compost, and plastics. Based on the results of two frontrunner studies, ferrous scrap and aluminum scrap in 2010, the first... 

The first step in the preparation of Pt-group metals is the dissolution of the raw materials (primary deposits, ores, metal scraps, supported catalysts, etc.). According to the characteristics of their content in the different mixed noble metals, different dissolution methods are used. Typical processes are dissolution in... 

The waste products of a home include paper, containers, tin cans, aluminum cans, and food scraps, as well as sewage. The waste products of industry and commerce include paper, wood, and metal scraps, as well as agricultural waste products. Biodegradable wastes, such as paper fines and industrial biosludge, into mixed alcohol fuels (e g., isopropanol, isobutanol, isopentanol). The wastes are first treated with lime to enhance reactivity. Then, they are converted to volatile fatly acids (VFAs) such as acetic acid, propionic acid, and butyric acid, using a mixed culture of microorganisms derived from cattle rumen or anaerobic waste treatment facihties. 

An application well-suited for IMS is the decommissioning and cleanup of sites where extensive manufacturing of explosives has taken place in the last century and where widespread contamination of soils and waters has occurred [74]. Decontamination of model metal scrap artificially contaminated with TNT and of decommissioned mortar rounds stiU containing explosives residue was followed by sampling surfaces with analysis by a portable mobility spectrometer. Mixed anaerobic microbial populations of bioslurries were employed in decontamination of scrap and the mortar rounds, and the IMS analyzer was seen as a sensitive field... 

Production, Import/Export, Use, and Release and Disposal. Information on the production, import, export, and use of nickel metal and nickel alloys is readily available (Chamberlain 1985 Kirk 1988a, 1988b NTD 1996 Tien and Howson 1981). However, information on the production, import, and use patterns of other nickel compounds is not generally available and is needed to assess human exposure to these compounds. Except for recycling of metal scrap, little information is available regarding the disposal of nickel and its compounds. 

The vendor states that MBS stabihzes heavy metals in soil, slndges, slag, ash, baghonse dnst, and sediment. Among the heavy metals treatable by the MBS process are arsenic, cad-minm, chrominm, copper, lead, mercnry, nickel, silver, and zinc. MBS technology is applicable in the following indnstries primary and secondary smelters, battery mannfactnrers and recyclers, ferrons and nonferrons fonndries, mnnicipal solid waste incinerators, anto and metal scrap recyclers, electronic mannfactnrers, electroplaters, ceramic prodnct mannfactnrers, and mineral refiners and processors. 

If the zinc and lead levels of the metal dust are relatively low, return of the dust to the furnace for iron recovery is feasible. This method is often employed with dusts generated by the production of stainless or alloy steels but is mostly impractical for handling dusts associated with carbon steel production. Because of the use of galvanized metal scrap in the production of carbon steels, these dusts tend to be high in zinc.
