Building and construction waste

Aggregates and concrete

Concrete aggregate collected from demolition sites is put through a crushing machine, often along with asphalt, bricks, dirt, and rocks. Smaller pieces of concrete are used as gravel for new construction projects. Crushed recycled concrete can also be used as the dry aggregate for new concrete if it is free of contaminants. Builder's rubble (like broken down bricks) is also used for railway ballast and gravel paths. This reduces the need for other rocks to be dug up, which in turn saves trees and habitats.

Asphalt and tarmac

Asphalt including asphalt shingle can be melted down and in part recycled. Tarmac can also be recycled and there is now an active market for recycling tarmac in the developed world. [1] This includes tarmac scalpings produced when roads are scarified before a new surface is laid.

Gypsum, plaster and plasterboard products

Because up to 17% of gypsum products are wasted during the manufacturing and installation processes. Wallboard (Australia and others), plasterboard, Gyp (New Zealand), drywall (USA) or plasterboard (UK and Ireland) is frequently not re-used and disposal can become a problem. Some landfill sites have banned dumping of gypsum because of the tendency to produce large volumes of hydrogen sulfide gas. Some manufacturers take back waste wallboards from construction sites and recycle it into new wallboard. [2] Gypsum waste from new construction, demolition and refurbishment activities can be turned into recycled gypsum through mechanical processes, and the recycled gypsum obtained can replace virgin gypsum in the Gypsum Industry. Some of the reasons for recycling this waste are:

Bricks

Intact bricks recovered from demolition can be cleaned and re-used.

Batteries

Some batteries contain toxic heavy metals, making recycling or proper disposal a high priority. These batteries are Dutch; the Netherlands openly encourages battery recycling. Varta batteries.JPG
Some batteries contain toxic heavy metals, making recycling or proper disposal a high priority. These batteries are Dutch; the Netherlands openly encourages battery recycling.

The large variation in size and type of batteries makes their recycling extremely difficult: [7] they must first be sorted into similar kinds and each kind requires an individual recycling process. Additionally, older batteries contain mercury and cadmium, harmful materials that must be handled with care. Because of their potential environmental damage, proper disposal of used batteries is required by law in many areas. Unfortunately, this mandate has been difficult to enforce. [8]

Lead-acid batteries, like those used in automobiles, are relatively easy to recycle and many regions have legislation requiring vendors to accept used products. In the United States, the recycling rate is 90%, with new batteries containing up to 80% recycled material. [8]

Japan, Kuwait, the USA, Canada, France, the Netherlands, Germany, Austria, Belgium, Sweden, the UK and Ireland all actively encourage battery recycling programs. [5] [6] [9] [10] In 2006, the EU passed the Battery Directive of which one of the aims is a higher rate of battery recycling. The EU directive said at least 25% of all the EU's used batteries must be collected by 2012, and rising to no less than 45% by 2016, of which, that at least 50% of them must be recycled. [10]

Biodegradable waste

Kitchen, garden, and other green waste can be recycled into useful material by composting into leaf mold and regular compost. This process allows natural aerobic bacteria to break down the waste into fertile topsoil. Much composting is done on a household scale, but municipal green-waste collection programs also exist. These programs can supplement their funding by selling the topsoil produced.

Electronic waste

Electronic recycling is recycling or reuse of computers or other electronics. It includes both finding another use for materials (such as donation to charity), and having systems dismantled in a manner that allows for the safe extraction of the constituent materials for reuse in other products. The direct disposal of electrical equipment—such as old computers and mobile phones is banned in many areas, such as the UK, parts of the USA, Japan, Ireland, Germany and the Netherlands, due to the toxic contents of certain components. The recycling process works by mechanically separating the metals, plastics, and circuit boards contained in the appliance. When this is done on a large scale at an electronic waste recycling plant, component recovery can be achieved cost-effectively.

With high lead content in CRTs, and the rapid diffusion of new flat-panel display technologies, some of which (LCDs) use lamps containing mercury, there is growing concern about electronic waste from discarded televisions. Related occupational health concerns exist, as well, for disassemblers and scrap dealers removing copper wiring and other materials from CRTs. Further environmental concerns related to television design and use relate to the devices' increasing electrical energy requirements. [11]

Computers that are termed trashware in North America or totally reconditioned hardware in the UK and Ireland are computer equipment that has assembled from old hardware, using cleaned and checked parts from different computers, for use by disadvantaged people to bridge the digital divide. Trashware is different from retrocomputing, which has only cultural and recreational purposes.

Ink jet printer cartridges

Because printer cartridges from the original manufacturer are often expensive, demand exists for cheaper third party options. These include ink sold in bulk, cartridge refill kits, machines in stores that automatically refill cartridges, re-manufactured cartridges, and cartridges made by a corporate entity other than the original manufacturer.

Consumers can refill ink cartridges themselves with a kit, or they can take the cartridge to a refiller or re-manufacturer where ink is pumped back into the cartridge. PC World reports that refilled cartridges have higher failure rates, print fewer pages than new cartridges, and demonstrate more on-page problems like streaking, curling, and colour bleed. [12]

Metals

A wide range of metals in commercial and domestic use have well developed recycling markets in most developed countries. Domestic recycling is commonly available for Iron [13] and steel, aluminium [13] and in particular beverage and food cans. In addition, building metals such as copper, [14] zinc [15] and lead [16] are readily recyclable through specialised companies. 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 [17] and chromium are also extracted from metal put into the recycling system but are rarely recovered from the general waste stream.

Paper and newsprint

Paper and newsprint can be recycled by reducing it to pulp and combining it with pulp from newly harvested wood. As the recycling process causes the paper fibres to break down, each time paper is recycled its quality decreases. This means that either a higher percentage of new fibres must be added, or the paper down-cycled into lower quality products. Any writing or colouration of the paper must first be removed by deinking, which also removes fillers, clays, and fibre fragments. [18]

Almost all paper can be recycled today, but some types are harder to recycle than others. Papers coated with plastic or aluminium foil, and papers that are waxed, pasted, or gummed are usually not recycled because the process is too expensive. [18]

Sometimes recyclers ask for the removal of the glossy paper inserts from newspapers because they are a different type of paper. Glossy inserts have a heavy clay coating that some paper mills cannot accept. Most of the clay is removed from the recycled pulp as sludge, which must be disposed of. If the coated paper is 20% by weight clay, then each ton of glossy paper produces more than 200 kg of sludge and less than 800 kg of fibre. [18]

The price of recycled paper has varied greatly over the last 30 or so years. [19] [20] [21] [22] [23] [24] The German price of €100/£49 per tonne was typical for the year 2003 [21] and it steadily rose over the years. By the September 2008 saw the American price of $235 per ton, which had fallen to just $120 per ton, [19] and in the January 2009, the UK's fell six weeks from about £70.00 per ton, to only £10.00 per ton. [22] The slump was probably due to the economic down turn in East Asia leading to market for waste paper drying up in China. [22] 2010 averaged at $120.32 over the start of the year, but saw a rapid rise global prices in May 2010, [20] with the June 2010 resting $217.11 per ton in the USA as China's paper market began to reopen! [20]

Mexico, America, the EU, Russia and Japan all recycle paper en masse and there are many state run and private schemes running in those countries. In 2004 the paper recycling rate in Europe was 54.6% or 45.5 million short tons (41.3 Mt). [25] The recycling rate in Europe reached 64.5%3 in 2007, which confirms that the industry is on the path to meeting its voluntary target of 66% by 2010. [26]

Plastic recycling is the processing of plastic waste into other products. [27] [28] [29] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [30] [31] Recycling rates lag those of other recoverable materials, such as aluminium, glass and paper. From the start of production through to 2015, the world produced some 6.3 billion tonnes of plastic waste, only 9% of which has been recycled, and only ~1% has been recycled more than once. [32] Of the remaining waste, 12% was incinerated and 79% either sent to landfill or lost into the environment as pollution. [32]

Almost all plastic is non-biodegradable and without recycling, spreads across the environment [33] [34] where it can cause harm. For example, as of 2015 approximately 8 million tons of waste plastic enter the oceans annually, damaging the ecosystem and forming ocean garbage patches. [35] Even the highest quality recycling processes lead to substantial plastic waste during the sorting and cleaning process, releasing large amounts of microplastics in waste water, and dust from the process. [36] [37]

Almost all recycling is mechanical: melting and reforming plastic into other items. This can cause polymer degradation at a molecular level, and requires that waste be sorted by colour and polymer type before processing, which is complicated and expensive. Errors can lead to material with inconsistent properties, rendering it unappealing to industry. [38] In feedstock recycling, waste plastic is converted into its starting chemicals, which can then become fresh plastic. This involves higher energy and capital costs. Alternatively, plastic can be burned in place of fossil fuels, in energy recovery facilities or biochemically converted into other useful chemicals for industry. In some countries, burning is the dominant form of plastic waste disposal, particularly where landfill diversion policies are in place.

Plastic recycling is low in the waste hierarchy. It has been advocated since the early 1970s, [39] but due to economic and technical challenges, did not impact plastic waste to any significant extent until the late 1980s. The plastics industry has been criticised for lobbying for expansion of recycling programs, even while research showed that most plastic could not be economically recycled. [40] [41] [42]

Rubber Tires

Tires are among the most problematic sources of waste. Progress in recycling has resulted in a major reduction in dumping.

Tire recycling, or rubber recycling, is the process of recycling waste tires that are no longer suitable for use on vehicles due to wear or irreparable damage. These tires are a challenging source of waste, due to the large volume produced, the durability of the tires, and the components in the tire that are ecologically problematic. [43]

Because tires are highly durable and non-biodegradable, they can consume valuable space in landfills. [43] If waste tires are improperly managed they may cause rubber pollution. In 1990, it was estimated that over 1 billion scrap tires were in stockpiles in the United States. As of 2015, only 67 million tires remain in stockpiles. [44] From 1994 to 2010, the European Union increased the amount of tires recycled from 25% of annual discards to nearly 95%, with roughly half of the end-of-life tires used for energy, mostly in cement manufacturing. [45] [46]

Pyrolysis and devulcanization could facilitate recycling. Aside from use as fuel, the main end use for tires remains ground crumb rubber. [44] [47] In 2017, 13% of U.S. tires removed from their primary use were sold in the used tire market. Of the tires that were scrapped, 43% were burnt as tire-derived fuel, with cement manufacturing the largest user, another 25% were used to make ground rubber, 8% were used in civil engineering projects, 17% were disposed of in landfills and 8% had other uses. [48] Globally, tire graveyards are a common environmental hazard, with significant pollutants and other challenges. For example, the Sulaibiya tire graveyard in Kuwait has had repeat highly toxic fires. [49]

Ship breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships either as a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. [51] Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about its use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. [52]

In 2012, roughly 1,250 ocean ships were broken down, and their average age was 26 years. [53] [54] In 2013, the world total of demolished ships amounted to 29,052,000 tonnes, 92% of which were demolished in Asia. As of January 2020, Alang Ship Breaking Yard in India has the largest global share at 30%, [55] followed by Chittagong Ship Breaking Yard in Bangladesh and Gadani Ship Breaking Yard in Pakistan. [56]

The largest sources of ships are China, Greece, and Germany, although there is a greater variation in the source of carriers versus their disposal. [57] The ship-breaking yards of India, Bangladesh, China and Pakistan employ 225,000 workers as well as providing many indirect jobs. In Bangladesh, the recycled steel covers 20% of the country's needs and in India it is almost 10%. [58]

As an alternative to ship breaking, ships may be sunk to create artificial reefs after legally mandated removal of hazardous materials (though this does not recycle any materials), or sunk in deep ocean waters. Storage is a viable temporary option, whether on land or afloat, though most ships will eventually be scrapped; some will be sunk, or preserved as museums.

Textiles

In many countries, there is an active market in re-selling used clothes. In Britain, this dominated by charity shops who sell donated clean clothes. Less saleable clothes are put into the re-cycling waste stream. Textiles are made of a variety of materials including cotton, wool, synthetic plastics, linen, modal and a variety of other materials. The textile's composition will affect its durability and method of recycling.

Textiles entering the re-cycling stream are sorted and separated by workers into good quality clothing and shoes which can be reused or worn. There is a trend of moving these facilities from developed countries to developing countries either for charity or sold at a cheaper price. [59] Many international organisations collect used textiles from developed countries as a donation to those third world countries. This recycling practise is encouraged because it helps to reduce unwanted waste while providing clothing to those in need. [60] Damaged textiles are further sorted into grades to make industrial wiping cloths and for use in high quality paper manufacture or material suitable for fibre reclamation and filling products. If textile reprocessors receive wet or soiled clothes, however, these may still be disposed of in a landfill, as the washing and drying facilities may not be present at sorting units. [61]

Fibre reclamation mills sort textiles according to fibre type and colour. Colour sorting eliminates the need to re-dye the recycled textiles. The textiles are shredded into "shoddy" fibres and blended with other selected fibres, depending on the intended end use of the recycled yarn. The blended mixture is carded to clean and mix the fibres and spun ready for weaving or knitting. The fibres can also be compressed for mattress production. Textiles sent to the flocking industry are shredded to make filling material for car insulation, roofing felts, loudspeaker cones, panel linings and furniture padding.

According to Earth911.com, "Metal hangers, while made of steel, can be difficult to recycle because their hooks can damage recycling equipment and some have a petroleum coating. Some curbside recycling programs do accept them.... Many dry cleaners take back hangers, too...." [62]

Chat and furnace slag

In North America, mine chat waste can be used on snow-covered roads to improve traction; as gravel; and as construction aggregate, principally for railway ballast, highway construction, and concrete production. Furnace slag and to a lesser degree coal slag have been used in lieu of construction and railway ballast gravel in the UK. Clinker, slag, fly ash and in some cases ashes have all historically been used in places such as the industrial parts of Yorkshire and South Wales to make domestic cinder paths.

Recycling is the process of converting waste materials into new materials and objects. This concept often includes the recovery of energy from waste materials. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution and water pollution.

Municipal solid waste (MSW), commonly known as trash or garbage in the United States and rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog. Although the waste may originate from a number of sources that has nothing to do with a municipality, the traditional role of municipalities in collecting and managing these kinds of waste have produced the particular etymology 'municipal.'

<span class="mw-page-title-main">Reuse</span> Using again

Reuse is the action or practice of using an item, whether for its original purpose or to fulfill a different function. It should be distinguished from recycling, which is the breaking down of used items to make raw materials for the manufacture of new products. Reuse—by taking, but not reprocessing, previously used items—helps save time, money, energy and resources. In broader economic terms, it can make quality products available to people and organizations with limited means, while generating jobs and business activity that contribute to the economy.

Landfill mining and reclamation (LFMR) is a process which excavates and processes solid wastes which have previously been landfilled. The process aims to reduce the amount of landfill mass encapsulated within the closed landfill and/or temporarily remove hazardous material to allow protective measures to be taken before the landfill mass is replaced. In the process, mining recovers valuable recyclable materials, a combustible fraction, soil, and landfill space. The aeration of the landfill soil is a secondary benefit with regard to the landfill's future use. The combustible fraction is useful for power generation. The overall appearance of the landfill mining procedure is a sequence of processing machines laid out in a functional conveyor system. The operating principle is to excavate, sieve and sort the landfill material.

There is no national law in the United States that mandates recycling. State and local governments often introduce their own recycling requirements. In 2014, the recycling/composting rate for municipal solid waste in the U.S. was 34.6%. A number of U.S. states, including California, Connecticut, Delaware, Hawaii, Iowa, Maine, Massachusetts, Michigan, New York, Oregon, and Vermont have passed laws that establish deposits or refund values on beverage containers while other jurisdictions rely on recycling goals or landfill bans of recyclable materials.

In 2015, 43.5% of the United Kingdom's municipal waste was recycled, composted or broken down by anaerobic digestion. The majority of recycling undertaken in the United Kingdom is done by statutory authorities, although commercial and industrial waste is chiefly processed by private companies. Local Authorities are responsible for the collection of municipal waste and operate contracts which are usually kerbside collection schemes. The Household Waste Recycling Act 2003 required local authorities in England to provide every household with a separate collection of at least two types of recyclable materials by 2010. Recycling policy is devolved to the administrations of Scotland, Northern Ireland and Wales who set their own targets, but all statistics are reported to Eurostat.

<span class="mw-page-title-main">Plastic</span> Material of a wide range of synthetic or semi-synthetic organic solids

Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be molded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to their widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives.

Recycling can be carried out on various raw materials. Recycling is an important part of creating more sustainable economies, reducing the cost and environmental impact of raw materials. Not all materials are easily recycled, and processing recyclable into the correct waste stream requires considerable energy. Some particular manufactured goods are not easily separated, unless specially process therefore have unique product-based recycling processes.

Recycling in Australia is a widespread, and comprehensive part of waste management in Australia, with 60% of all waste collected being recycled. Recycling is collected from households, commercial businesses, industries and construction. Despite its prominence, household recycling makes up only a small part (13%) of Australia's total recycling. It generally occurs through kerbside recycling collections such as the commingled recycling bin and food/garden organics recycling bin, drop-off and take-back programs, and various other schemes. Collection and management of household recycling typically falls to local councils, with private contractors collecting commercial, industrial and construction recycling. In addition to local council regulations, legislation and overarching policies are implemented and managed by the state and federal governments.

China's waste import ban, instated at the end of 2017, prevented foreign inflows of waste products. Starting in early 2018, the government of China, under Operation National Sword, banned the import of several types of waste, including plastics with a contamination level of above 0.05 percent. The ban has greatly affected recycling industries worldwide, as China had been the world's largest importer of waste plastics and processed hard-to-recycle plastics for other countries, especially in the West.

<span class="mw-page-title-main">Waste management in South Korea</span>

Waste management in South Korea involves waste generation reduction and ensuring maximum recycling of the waste. This includes the appropriate treatment, transport, and disposal of the collected waste. South Korea's Waste Management Law was established in 1986, replacing the Environmental Protection Law (1963) and the Filth and Cleaning Law (1973). This new law aimed to reduce general waste under the waste hierarchy in South Korea. This Waste Management Law imposed a volume-based waste fee system, effective for waste produced by both household and industrial activities.
