"dealers often purchase aluminium cans in bulk, even when deposits are not offered. Aluminium is one of the most cost-effective materials to recycle. When recycled without other metals being mixed in, the can–lid combination is perfect for producing new stock for the main part of the can—the loss of magnesium during melting is made up for by the high magnesium content of the lid. Also, reducing ores such as bauxite into aluminium requires large amounts of electricity, making recycling cheaper than producing new metal. Aluminium cans are coated internally to protect the aluminium from oxidizing. Despite this coating, trace amounts"
"aluminium recycling and steel cans being the most common items. Metal can be recycled indefinitely, and aluminium cans use just 5% of the energy needed to produce them from scratch and only release 5% of the amount of greenhouse gases. In addition, it is the easiest material to extract and separate from the other reyclables, using magnets for steel cans and special magnets (eddy currents) it guarantees recycling of every can. In 2013, the Alliance for Beverage Cartons and the Environment and Sonoco Alcore opened the UK's first carton recycling facility in Halifax. Prior to this, recycling was limited because"

In the UK, these are usually either specialised scrap dealers or car breakers. Other metals present in smaller quantities in the domestic waste stream such as tin and chromium are also extracted from metal put into the recycling system but are rarely recovered from the general waste stream. Paper and newsprint can be recycled by reducing it to pulp and combining it with pulp from newly harvested wood. As the recycling process"
"versus aluminium debate may make sense in connection with beer bottles, soft drinks are another matter. The majority of those bottles are currently plastic, while most beer bottles are glass. Aluminium is a silver-white, soft metal and the most abundant metallic element, comprising 1/12 of the Earth's crust. Aluminum is always found combined with oxygen or other elements in nature and must be processed from ore to produce workable aluminium metal. Aluminum metal is one of the most widely recycled industrial materials due to ease of remelting used aluminum and the expense of processing natural aluminum ores. Bottlecans are made"
"in 1962 for the Pittsburgh Brewing Company and is now used in nearly 100% of the canned beer market. Aluminum cans are often made with recycled aluminum; approximately 68% of a standard North American can is recycled aluminum. In 2012, 92% of the aluminum beverage cans sold in Switzerland were recycled. Cans are the most recycled beverage container, at a rate of 69% worldwide. According to Alcoa Aluminum Company, in 2015 about 34 cans are required to achieve a weight of one pound. The unstated assumption is that most of those will be the normal 12-oz type can.

"contained in a manufactured product. In volume, copper is the third most recycled metal after iron and aluminium. Iron and steel are the world's most recycled materials, and among the easiest materials to reprocess, as they can be separated magnetically from the waste stream. Recycling is via a steelworks: scrap is either remelted in an electric arc furnace (90-100% scrap), or used as part of the charge in a Basic Oxygen Furnace (around 25% scrap). Any grade of steel can be recycled to top quality new metal, with no 'downgrading' from prime to lower quality materials as steel is recycled"
"types of plastic, PET (#1) and HDPE (#2), are collected. This separation is usually done by hand but has become automated in some sorting centers: a spectroscopic scanner is used to differentiate between different types of paper and plastic based on the absorbed wavelengths, and subsequently divert each material into the proper collection channel. Strong magnets are used to separate out ferrous metals, such as iron, steel, and tin cans. Non-ferrous metals are ejected by magnetic eddy currents in which a rotating magnetic field induces an electric current around the aluminum cans, which in turn creates a magnetic eddy current"
"Drink can A drink can (or beverage can) is a metal container designed to hold a fixed portion of liquid such as carbonated soft drinks, alcoholic drinks, fruit juices, teas, herbal teas, energy drinks, etc. Drink cans are made of aluminium (75% of worldwide production) or tin-plated steel (25% worldwide production). Worldwide production for all drink cans is approximately 370 billion cans per year worldwide. The first commercial beer available in cans began in 1935 in Richmond, Virginia. Not long after that, sodas, with their higher acidity and somewhat higher pressures, were available in cans. The key development for storing"
"Aluminium recycling Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (), which must first be mined from bauxite ore and then refined using the Bayer process. Recycling scrap aluminium requires only 5% of the energy used to make new aluminium from the raw ore. For this reason, approximately 36% of all aluminium produced in the United States comes from old recycled scrap. Used beverage containers are"
"can be reprocessed into new products. Material for recycling may be collected separately from general waste using dedicated bins and collection vehicles, a procedure called kerbside collection. In some communities, the owner of the waste is required to separate the materials into different bins (e.g. for paper, plastics, metals) prior to its collection. In other communities, all recyclable materials are placed in a single bin for collection, and the sorting is handled later at a central facility. The latter method is known as ""single-stream recycling."" The most common consumer products recycled include aluminium such as beverage cans, copper such as"
"Recovery boiler Recovery boiler is the part of Kraft process of pulping where chemicals for white liquor are recovered and reformed from black liquor, which contains lignin from previously processed wood. The black liquor is burned, generating heat, which is usually used in the process or in making electricity, much as in a conventional steam power plant. The invention of the recovery boiler by G.H. Tomlinson in the early 1930s was a milestone in the advancement of the kraft process. Recovery boilers are also used in the (less common) sulfite process of wood pulping; this article deals only with recovery"
"Battery recycling Battery recycling is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste. Batteries contain a number of heavy metals and toxic chemicals and disposing of them by the same process as regular trash has raised concerns over soil contamination and water pollution. Most types of batteries can be recycled. However, some batteries are recycled more readily than others, such as lead–acid automotive batteries (nearly 90% are recycled) and button cells (because of the value and toxicity of their chemicals). Rechargeable nickel–cadmium (Ni-Cd), nickel metal hydride (Ni-MH), lithium-ion (Li-ion) and nickel–zinc"

They all use reverse vending machines to collect them: for bottles and in most places for the PET bottles they use a Wincor-Nixdorf or a Tomra machine, while ALU cans are collected by the Hungarian ALU-press machine. Its advantage is that it accepts flattened or pressed cans as well, and it crushes them with a pressing machine, thus improving the storage capacity of the machine.

Much can recycling occurs at the smelters, but individual consumers also directly reuse cans in various ways. For instance some people use two tin cans to form a camp or survival stove to cook small meals. Tin is corrosion resistant, but acidic food like fruits and vegetables can corrode the tin layer. Nausea, vomiting, and diarrhea have been reported after ingesting canned food containing 200 mg/kg of tin. A 2002 study showed that 99.5% of 1200 tested cans contained below the UK regulatory"

In many countries, PET plastics are coded with the resin identification code number ""1"" inside the universal recycling symbol, usually located on the bottom of the container. HDPE is commonly used in bottles, particularly bottles (or jugs) of milk. Recycling code 2 is applicable. In the US, only about 30-35% of HDPE bottles are recycled. Container deposit legislation are laws passed by city, state, provincial, or national governments."
"agents are all used to exchange cations or anions with the solution. Selectivity and recovery are a function of the reagents used and the contaminants present. Metal recovery is the final step in a hydrometallurgical process. Metals suitable for sale as raw materials are often directly produced in the metal recovery step. Sometimes, however, further refining is required if ultra-high purity metals are to be produced. The primary types of metal recovery processes are electrolysis, gaseous reduction, and precipitation. For example, a major target of hydrometallurgy is copper, which is conveniently obtained by electrolysis. Cu ions reduce at mild potentials,"

This press is known as a conversion press which forms an integral rivet button in the lid and scores the opening, while concurrently forming the tabs in another die from a separate strip of aluminium. Early metal drink cans had no tabs; they were opened by a can-piercer or churchkey, a device resembling a bottle opener with a sharp point. The can was opened by punching two triangular holes in the lid—a large one for drinking, and a second (smaller) one"
"Glass recycling Glass recycling is the processing of waste glass into usable products. Glass waste should be separated by chemical composition, and then, depending on the end use and local processing capabilities, might also have to be separated into different colors. Many recyclers collect different colors of glass separately since glass retains its color after recycling. The most common types used for consumer containers are colorless glass, green glass, and brown or amber glass. Glass is ideal for recycling since none of the material is degraded by normal use. Glass makes up a large component of household and industrial waste"

Cans can be made with easy open features. Some cans have screw caps for pouring liquids and resealing. Some have hinged covers or slip-on covers for easy access. Paint cans often have a removable plug on the top for access and for reclosing. Steel from cans and other sources is the most recycled packaging material. Around 65% of steel cans are recycled. In the United States, 63% of steel cans are"

Magnesium oxide is recovered in a wet scrubber to give a slurry of magnesium hydroxide. This magnesium hydroxide slurry is then used in another scrubber to absorb sulfur dioxide from the flue gases producing a magnesium bisulfite solution that is clarified, filtered and used as the pulping liquor. Sodium-based processes use a recovery system similar to that used in the kraft recovery process, except that there is no ""lime cycle"". The sulfite"

Bioresorbable metal Bioresorbable (also called biodegradable or bioabsorbable) metals are metals or their alloys that degrade safely within the body. The primary metals in this category are magnesium-based and iron-based alloys, although recently zinc has also been investigated. Currently, the primary uses of bioresorbable metals are as stents for blood vessels (for example bioresorbable stents)"

The use of recycled aluminium also decreases the need for mining bauxite. The vast amount of aluminium used means that even small percentage losses are large expenses, so the flow of material is well monitored and accounted for financial reasons. Efficient production and recycling benefits the environment as well. Aluminium beverage cans are usually recycled by the following method: The scrap aluminium is separated into a range of categories ""e.g."" irony aluminium (engine blocks etc.), clean aluminium (alloy wheels).

Instead of mixing recycled metal with more aluminum (to soften it) or magnesium (to harden it), a new approach uses annealing to produce an alloy that works for both. The aluminum can is also considered the most valuable recyclable material in an average recycling bin. It is estimated that Americans throw away nearly 1 billion dollars a year in wasted aluminum. The aluminum industry pays nearly 800 million dollars a year for recycled aluminum since it is so versatile."

Technical quality HCl at typically 18% concentration is the most commonly used pickling agent for the pickling of carbon steel grades. The spent acid has long been reused as iron(II) chloride (also known as ferrous chloride) solutions, but high heavy-metal levels in the pickling liquor have decreased this practice. The steel pickling industry has developed hydrochloric acid regeneration processes, such as the spray roaster or the fluidized bed HCl regeneration process,"
