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.


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

. 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. Shape classification contributes to the dynamics of the material. Classification by density is important when it comes to determining the use of a material.

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 The Waste Electrical and Electronic Equipment Directive (WEEE Directive) is the European Community Directive 2012/19/EU on waste electrical and electronic equipment (WEEE) which, together with the RoHS Directive 2011/65/EU, 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. Appliance manufacturers are now required to finance the recycling of their products. The Association for Electric Home Appliances is a trade group that is responsible for orphaned products.


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.


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 {{Unreferenced, date=May 2009 The Electronic Waste Recycling Act of 2003 (2003 Cal ALS 526) (EWRA) is a California law to reduce the use of certain hazardous substances in certain electronic products sold in the state. The act was signed into law Se ...
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.Electronic Hazardous Waste. (2010). Retrieved from Department of Toxic Substances Control website: http://www.dtsc.ca.gov/hazardouswaste/ewaste/ 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

”, recycling and final disposal of the product. 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. 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.
