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.
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes.
Electronic waste recycling, electronics recycling, or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of e-waste, the terms like computer recycling or mobile phone recycling may be used. Like other waste streams, reuse, donation, and repair are common sustainable ways to dispose of IT waste.
Glass recycling is the processing of waste glass into usable products. Glass that is crushed or imploded and ready to be remelted is called cullet. There are two types of cullet: internal and external. Internal cullet is composed of defective products detected and rejected by a quality control process during the industrial process of glass manufacturing, transition phases of product changes and production offcuts. External cullet is waste glass that has been collected or reprocessed with the purpose of recycling. External cullet is classified as waste. The word "cullet", when used in the context of end-of-waste, will always refer to external cullet.
Electronic waste describes discarded electrical or electronic devices. It is also commonly known as waste electrical and electronic equipment (WEEE) or end-of-life (EOL) electronics. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution. The growing consumption of electronic goods due to the Digital Revolution and innovations in science and technology, such as bitcoin, has led to a global e-waste problem and hazard. The rapid exponential increase of e-waste is due to frequent new model releases and unnecessary purchases of electrical and electronic equipment (EEE), short innovation cycles and low recycling rates, and a drop in the average life span of computers.
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.
Environmental harmful product dumping is the practice of transfrontier shipment of waste from one country to another. The goal is to take the waste to a country that has less strict environmental laws, or environmental laws that are not strictly enforced. The economic benefit of this practice is cheap disposal or recycling of waste without the economic regulations of the original country.
A waste picker is a person who salvages reusable or recyclable materials thrown away by others to sell or for personal consumption. There are millions of waste pickers worldwide, predominantly in developing countries, but increasingly in post-industrial countries as well.
Guiyu, in Guangdong Province, China, is widely perceived as the largest electronic waste (e-waste) site in the world. In 2005, there were 60,000 e-waste workers in Guiyu who processed the more than 100 truckloads that were transported to the 52-square-kilometre area every day. The constant movement into and processing of e-wastes in the area leading to the harmful and toxic environment and living conditions, coupled with inadequate facilities, have led to the Guiyu town being nicknamed the "electronic graveyard of the world".
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
As a trade association, the British Metals Recycling Association (BMRA) represents over 300 organisations working across UK’s metal recycling sector. Its website also helps members of the public to find a local metal recycling organisation. It is based in Cambridgeshire, England.
Products made from a variety of materials can be recycled using a number of processes.
Mobile phone recycling describes the waste management of mobile phones, to retrieve materials used in their manufacture. Rapid technology change, low initial cost, and planned obsolescence have resulted in a fast-growing surplus, which contributes to the increasing amount of electronic waste around the globe.
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 way 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.
Agbogbloshie is a nickname of a commercial district on the Korle Lagoon of the Odaw River, near the center of Accra, Ghana's capital city in the Greater Accra region. Near the slum called "Old Fadama", the Agbogbloshie site became known as a destination for externally generated automobile and electronic scrap collected from mostly the western world. It was a center of a legal and illegal exportation network for the environmental dumping of electronic waste (e-waste) from industrialized nations. The Basel Action Network, a small NGO based in Seattle, has referred to Agbogbloshie as a "digital dumping ground", where they allege millions of tons of e-waste are processed each year.
A circular economy is a model of resource production and consumption in any economy that involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products for as long as possible. The concept aims to tackle global challenges such as climate change, biodiversity loss, waste, and pollution by emphasizing the design-based implementation of the three base principles of the model. The three principles required for the transformation to a circular economy are: designing out waste and pollution; keeping products and materials in use, and regenerating natural systems. CE is defined in contradistinction to the traditional linear economy. The idea and concepts of a circular economy have been studied extensively in academia, business, and government over the past ten years. It has been gaining popularity because it can help to minimize carbon emissions and the consumption of raw materials, open up new market prospects, and, principally, increase the sustainability of consumption.
Techreturns Nederland BV (2009-2014) was a Dutch company founded with the aim to reduce electronic waste by buying used electronics, especially mobile phones, from consumers and companies to repair them and give them a second life. Techreturns was founded in Amsterdam in 2009. It was member of Social Enterprise Nederland, an organization that supports social enterprises. Techreturns was declared bankrupt in December 2014.
In Egypt, waste and lack of proper management of it pose serious health and environmental problems for the country and its population. There has been some governmental attempts to better the system of waste management since the 1960s but those have not proven sufficient until now. In the last 10 years focus on this issue and solutions to it has increased both from the government and civil society. Some attempts at recycling are present, and growing in the country. But these are largely informal or private actors, and government initiatives are necessary to properly manage these systems and provide them with appropriate resources.
Electrical and electronic equipment (EEE) waste, or e-waste, is illegally brought into African states every year. A minimum of 250,000 metric tons of e-waste comes into the continent, and according to the Swiss Federal Laboratories for Materials Science and Technology, the majority of it in West Africa enters from Europe. Developed countries commodify underdeveloped African states as dumping grounds for their e-waste, and due to poor regulations and a lack of enforcement institutions, illegal dumping is promoted. Currently, the largest e-waste dumping site in Africa is Agbogbloshie in Ghana. While states like Nigeria do not contain e-waste sites as concentrated as Agbogbloshie, they do have several small sites.
Informal waste collection is the activity of "manually sorting and extracting various recyclable and reusable materials from mixed waste, at legal and illegal dumpsites, on top of or under piles of waste, in bins, at various transfer points, in transport trucks or elsewhere". When this activity is carried out in bins, the term "scavenging" is used. This activity is one way of collecting waste, the other ways consisting of collecting it at source or collecting it in an organised way.
