Hazardous waste is waste that must be handled properly to avoid damaging human health or the environment. Waste can be hazardous because it is toxic, reacts violently with other chemicals, or is corrosive, among other traits. As of 2022, humanity produces 300-500 million metric tons of hazardous waste annually. Some common examples are electronics, batteries, and paints. An important aspect of managing hazardous waste is safe disposal. Hazardous waste can be stored in hazardous waste landfills, burned, or recycled into something new. Managing hazardous waste is important to achieve worldwide sustainability. Hazardous waste is regulated on national scale by national governments as well as on an international scale by the United Nations (UN) and international treaties.
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.
Chemical waste is any excess, unused, or unwanted chemical. Chemical waste may be classified as hazardous waste, non-hazardous waste, universal waste, or household hazardous waste, each of which is regulated separately by national governments and the United Nations. Hazardous waste is material that displays one or more of the following four characteristics: ignitability, corrosivity, reactivity, and toxicity. This information, along with chemical disposal requirements, is typically available on a chemical's Safety Data Sheet (SDS). Radioactive and biohazardous wastes require additional or different methods of handling and disposal, and are often regulated differently than standard hazardous wastes.
Eastman Chemical Company is an American company primarily involved in the chemical industry. Once a subsidiary of Kodak, today it is an independent global specialty materials company that produces a broad range of advanced materials, chemicals and fibers for everyday purposes. Founded in 1920 and based in Kingsport, Tennessee, the company operates 36 manufacturing sites worldwide and employs approximately 14,000 people.
Green chemistry, similar to sustainable chemistry or circular chemistry, is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. While environmental chemistry focuses on the effects of polluting chemicals on nature, green chemistry focuses on the environmental impact of chemistry, including lowering consumption of nonrenewable resources and technological approaches for preventing pollution.
Extended producer responsibility (EPR) is a strategy to add all of the estimated environmental costs associated with a product throughout the product life cycle to the market price of that product, contemporarily mainly applied in the field of waste management. Such societal costs are typically externalities to market mechanisms, with a common example being the impact of cars.
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans. This applies to industries that generate wastewater with high concentrations of organic matter, toxic pollutants or nutrients such as ammonia. Some industries install a pre-treatment system to remove some pollutants, and then discharge the partially treated wastewater to the municipal sewer system.
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.
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.'
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.
Design for the environment (DfE) is a design approach to reduce the overall human health and environmental impact of a product, process or service, where impacts are considered across its life cycle. Different software tools have been developed to assist designers in finding optimized products or processes/services. DfE is also the original name of a United States Environmental Protection Agency (EPA) program, created in 1992, that works to prevent pollution, and the risk pollution presents to humans and the environment. The program provides information regarding safer chemical formulations for cleaning and other products. EPA renamed its program "Safer Choice" in 2015.
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 household waste has raised concerns over soil contamination and water pollution. While reducing the amount of pollutants being released through disposal through the uses of landfill and incineration, battery recycling can facilitate the release of harmful materials from batteries to both the environment and the workers recycling batteries.

Waste are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.
The environmental impact of paper are significant, which has led to changes in industry and behaviour at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, disposable paper became a relatively cheap commodity, which led to a high level of consumption and waste. The rise in global environmental issues such as air and water pollution, climate change, overflowing landfills and clearcutting have all lead to increased government regulations. There is now a trend towards sustainability in the pulp and paper industry as it moves to reduce clear cutting, water use, greenhouse gas emissions, fossil fuel consumption and clean up its influence on local water supplies and air pollution.
Sustainable Electronics Initiative (SEI) is an initiative started in the United States in the summer of 2009 by the Illinois Sustainable Technology Center, which is a division of the Institute of Natural Resource Sustainability of the University of Illinois at Urbana-Champaign. SEI is dedicated to developing and implementing sustainable means for the design, manufacturing, remanufacturing, and recycling of electronics Members of SEI include individuals from academia, non-profit organizations, government agencies, manufacturers, designers, recyclers and refurbishers.
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 nation, Americans generate more waste than any other nation in the world, officially with 4.4 pounds (2.0 kg) of municipal solid waste (MSW) per person per day, with another study estimating 7.1 pounds (3.2 kg) per capita per day. Fifty five percent of this waste is contributed as residential garbage, while the remaining forty five percent of waste in the U.S.'s 'waste stream' comes from manufacturing, retailing, and commercial trade in the U.S. economy. According to the American Society of Civil Engineers, Nevada produces the most waste at "[nearly] 8 pounds (3.6 kg) per person per day". Approximately 90% of all waste produced by Nevadans ends up in landfills. "Wasteful" states Michigan, New Mexico, Wisconsin and Oregon as well as Washington also dominated the list's 5-year period.
Green engineering approaches the design of products and processes by applying financially and technologically feasible principles to achieve one or more of the following goals: (1) decrease in the amount of pollution that is generated by a construction or operation of a facility, (2) minimization of human population exposure to potential hazards, (3) improved uses of matter and energy throughout the life cycle of the product and processes, and (4) maintaining economic efficiency and viability. Green engineering can be an overarching framework for all design disciplines.
Sustainable Materials Management is a systemic approach to using and reusing materials more productively over their entire lifecycles. It represents a change in how a society thinks about the use of natural resources and environmental protection. By looking at a product's entire lifecycle new opportunities can be found to reduce environmental impacts, conserve resources, and reduce costs.
