Appliance recycling is the process of dismantling scrapped home appliances to recover their parts or materials for reuse. Recycling appliances for their original or other purposes, involves disassembly, removal of hazardous components and destruction of the equipment to recover materials, generally by shredding, sorting and grading. [1] The rate at which appliances are discarded has increased due in part to obsolescence due to technological advancement, and in part to not being designed to be repairable. The main types of appliances that are recycled are televisions, refrigerators, air conditioners, washing machines, and computers. When appliances are recycled, they can be looked upon as a valuable resources; if disposed of improperly, they can be environmentally harmful and poison ecosystems.

Contents

The strength of appliance recycling legislation and the percentage of appliances recycled varies around the world.

Disassembly

A key part of appliance recycling is the manual dismantling of each product, removing hazardous components, and recovering reusable materials and parts. Procedures vary and depend on the appliance type. The amount of hazardous components able to be removed also depends on the type of appliance. Low removal rates of hazardous components reduce the recyclability of valuable materials. Each type of appliance has its own set of characteristics and components. This makes characterization of appliances essential to sorting and separating parts. Research on appliance dismantling has become an active area, intending to help recycling reach maximum efficiency. [2]

Classification

There is a certain process used to recover materials from appliances. Parts are generally removed in order from largest to smallest. Metals are extracted first and then plastics. Materials are sorted by either size, shape, or density. Sizing is a good means of sorting to quicken future processing. It also classifies fractions that show composition. Materials report to larger or finer fractions based on original dimension, toughness, or brittleness. [1] Shape classification contributes to the dynamics of the material. Classification by density is important when it comes to determining the use of a material.

Example

Batteries and copper are sorted out first for quality control purposes. The materials are then compacted. Next, iron and steel (ferrous metals) are extracted using electromagnets. They are collected and made ready for sale. Then metals are separated from non-metals using eddy currents created by rapidly alternating magnetic fields, which induce metals to jump away from non-metals. Then water separation is used to sort plastics and glass from circuit boards and copper wires. Circuit boards and copper content is then sold. Plastics and glass are further compacted for reuse. [3]

Recycling by region

Although appliance recycling is relatively new, several countries have enacted laws and regulations regarding electric waste. The first countries to establish home appliance recycling included Japan, Switzerland, Sweden, the Netherlands, and Germany.

European Union

In 2003 the Waste Electrical and Electronic Equipment Directive (WEEE) became European Law. It sets collection, recycling and recovery targets for all types of electrical goods.

Japan

By the 1950s and 60s Japan had already become a major producer of electric appliances. The first initiatives to recycle were launched in the 70s. Due to costs, disassembly was hardly achievable. The Home Appliance Recycling Law was enacted in 1998 and came into force in 2001, and recycling of waste electrics became a legal requirement under the Specific Household Appliance Recycling Law and the Law for Promotion of Effective Utilisation Resources. [1] Appliance manufacturers are now required to finance the recycling of their products. [4] The Association for Electric Home Appliances is a trade group that is responsible for orphaned products. [5]

China

China produces a significant proportion of the world's appliances, and imports a large quantity of waste appliances. There has not been much progress in appliance recycling efficiency. China's undeveloped dismantling and processing has led to elevated levels of toxic chemicals in and near waste appliance sites. [6]

United States

The United States is the largest waste appliance producer in the world. There is no federal law requiring appliance recycling; legislation varies between states. On a state level, many mandatory electronic recovery programs have been implemented. There are several commercial appliance recyclers.

California

In 2003, the California Electronic Waste Recycling Act was signed. It established a new program for consumers to return, recycle, and ensure the safe and environmentally sound disposal of video display devices, such as televisions and computer monitors, that are hazardous wastes when discarded. [7] In 2005, consumers began paying a 6-10 dollar fee when buying an electronic device. These fees are used to pay e-waste collectors and recyclers to cover their cost of managing e-waste. The EWRA classifies e-waste by dividing the products into two categories: electronic devices and covered electronic devices. Only covered electronic devices (CEDs) are included in the EWRA, however all electronic devices needed recycling measures to be taken. The CEDs include televisions and computers that have LCD displays or contain cathode ray tubes.

Australia

There are several commercial appliance recyclers in Australia. Some organisations that remove waste appliances and offer government-sponsored rebates. Some retailers including Appliances Online remove and recycle customers' old appliances. [8]

New Zealand

In New Zealand there is a push to keep old appliances and e-waste out of landfills, however there is little legislation to preventing this. As in Australia there are companies including the manufacturer Fisher and Paykel that remove waste appliances and recycle them. [9]

EPR

Extended producer responsibility (EPR) is defined as an environmental protection strategy that makes the manufacturer of the appliance responsible for its entire life cycle and especially for the “take-back”, recycling and final disposal of the product. [2] Essentially, manufacturers must now finance product treatment and recycling. Countries where this strategy has been adopted for waste appliances are: Switzerland (1998), Denmark (1999), Netherlands (1999), Norway (1999), Belgium (2001), Japan (2001), Sweden (2001) and Germany (2005), but it has also been expanded through legislation among certain South American countries such as Argentina, Brazil, Colombia and Peru. Countries in which EPR has long been established, demonstrate that the combination of government legislation and sound company practices can produce a higher take-back and recycling rate. An example of this is the Sony Corporation in Japan, achieving a 53% recycling rate. [2] Other ways countries approach the issue of waste appliances is either by offering recycling facilities or banning importation. Almost all countries, at least offer facilities that aid in appliance recycling. Many implement extended producer responsibility, in addition to recycling facilities.

Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. 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.

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">Vehicle recycling</span> Dismantling of vehicles for spare parts

Vehicle recycling is the dismantling of vehicles for spare parts. At the end of their useful life, vehicles have value as a source of spare parts and this has created a vehicle dismantling industry. The industry has various names for its business outlets including wrecking yard, auto dismantling yard, car spare parts supplier, and recently, auto or vehicle recycling. Vehicle recycling has always occurred to some degree but in recent years manufacturers have become involved in the process. A car crusher is often used to reduce the size of the scrapped vehicle for transportation to a steel mill.

The End of Life Vehicles Directive is a Directive of the European Union addressing the end of life for automotive products. Every year, motor vehicles which have reached the end of their useful lives create between 8 and 9 million tonnes of waste in the European Union. In 1997, the European Commission adopted a Proposal for a Directive to tackle this problem.

<span class="mw-page-title-main">Electronic waste in the United States</span>

Electronic waste or e-waste in the United States refers to electronic products that have reached the end of their operable lives, and the United States is beginning to address its waste problems with regulations at a state and federal level. Used electronics are the quickest-growing source of waste and can have serious health impacts. The United States is the world leader in producing the most e-waste, followed closely by China; both countries domestically recycle and export e-waste. Only recently has the United States begun to make an effort to start regulating where e-waste goes and how it is disposed of. There is also an economic factor that has an effect on where and how e-waste is disposed of. Electronics are the primary users of precious and special metals, retrieving those metals from electronics can be viewed as important as raw metals may become more scarce

<span class="mw-page-title-main">Electronic waste by country</span>

Electronic waste is a significant part of today's global, post-consumer waste stream. Efforts are being made to recycle and reduce this waste.

Products made from a variety of materials can be recycled using a number of processes.

Electronic waste in Japan is a major environmental issue. Although Japan was one of the first countries to implement an electronic waste recycling program, it is still having serious issues. In this day and age, e-waste disposal has become of major importance due to the increasing demand for electronics on a worldwide scale. In 2013, the Japanese government reported that roughly 550 thousand tonnes of e-waste was collected and treated in Japan, which only equates to about 24-30% of total e-waste. Not only does e-waste harm the environment if untreated, it also becomes a fiscal loss due to the material lost that could have been salvaged.

Electronic waste or e-waste in China refers to electronic products that are no longer usable and are therefore dumped or recycled. China is the world's largest importer and producer of electronic waste with over 70% of all global e-waste ending up in the world's largest dumpsites. An estimated 60–80% of this e-waste is handled through illegal informal recycling processes, without the necessary safety precautions legally required by Chinese government regulations. Processing e-waste in this directly causes serious environmental damage and permanent health risks in areas surrounding the disposal sites. While the Chinese government and the international community have taken action to regulate e-waste management, ineffective enforcement, legislative loopholes, and the pervasiveness of informal recycling have been obstacles to mitigating the consequences of e-waste.

Electronic waste is emerging as a serious public health and environmental issue in India. India is the "Third largest electronic waste producer in the world"; approximately 2 million tons of e-waste are generated annually and an undisclosed amount of e-waste is imported from other countries around the world.

The guideline committee VDI 2343 "Recycling of electrical and electronic devices" was initiated in 1996 by Ralf Brüning. The aim is to develop practical and legally compliant recommendations for action in order to support the affected groups in their work, for expample disposal companies, manufacturers, universities, authorities, lawyers, environmental associations, reuse companies. Thereby among other things the aspects of logistics, dismantling, processing, recycling and reuse are dealt with in seven sub-committees and coordinated in an overall committee.
