Substitution Principle (sustainability)
The substitution principle in sustainability is the maxim of how processes, services, and products should be replaced with alternatives that result in a lower environmental impact. An example of a strong, hazard-based interpretation of the substitution principle in application regarding chemicals considers the overall impact: "hazardous chemicals should be substituted by less hazardous alternatives or preferably alternatives that mitigates identifiable hazards impacts". Overview The principle has historically been promoted by environmental groups. This concept is becoming increasingly mainstream, being a key concept in green chemistry and a central element of EU REACH regulation. Critics of the principle claim it is very difficult to implement in reality, especially in terms of legislation Legislation is the process or result of enrolling, enacting, or promulgating laws by a legislature, parliament, or analogous governing body. Before an item of legislation becomes law i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainability
Sustainability is a social goal for people to co-exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time. Sustainability usually has three dimensions (or pillars): environmental, economic, and social. Many definitions emphasize the environmental dimension. This can include addressing key environmental problems, including climate change and biodiversity loss. The idea of sustainability can guide decisions at the global, national, organizational, and individual levels. A related concept is that of sustainable development, and the terms are often used to mean the same thing. UNESCO distinguishes the two like this: "''Sustainability'' is often thought of as a long-term goal (i.e. a more sustainable world), while ''sustainable development'' refers to the many processes and pathways to achieve it." Details around the economic dimension of sustainability are controversial. Scholars have discussed this under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical
A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. If a mixture is separated to isolate one chemical substance to a desired degree, the resulting substance is said to be chemically pure. Chemical substances can exist in several different physical states or phases (e.g. solids, liquids, gases, or plasma) without changing their chemical composition. Substances transition between these phases of matter in response to changes in temperature or pressure. Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bonded to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Group
The environmental movement (sometimes referred to as the ecology movement) is a social movement that aims to protect the natural world from harmful environmental practices in order to create sustainable living. In its recognition of humanity as a participant in (not an enemy of) ecosystems, the movement is centered on ecology, health, as well as human rights. The environmental movement is an international movement, represented by a range of environmental organizations, from enterprises to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. At its broadest, the movement includes private citizens, professionals, religious devotees, politicians, scientists, nonprofit organizations, and individual advocates like former Wisconsin Senator Gaylord Nelson and Rachel Carson in the 20th century. Since the 1970s, public awareness, envir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Chemistry
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 pollutant, polluting chemicals on nature, green chemistry focuses on the environmentalism, environmental impact of chemistry, including lowering consumption of nonrenewable resources and technological approaches for preventing pollution. The overarching goals of green chemistry—namely, more resource-efficient and inherently safer design of molecules, materials, products, and processes—can be pursued in a wide range of contexts. History Green chemistry emerged from a variety of existing ideas and research efforts (such as atom economy and catalysis) in the period leading up to the 1990s, in the context of increasing attention to problems of chemical pollution and resource depletio ...

Registration, Evaluation, Authorisation And Restriction Of Chemicals
Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) is a European Union regulation dating from 18 December 2006, amended on 16 December 2008 by Regulation (EC) No 1272/2008. REACH addresses the production and use of chemical substances, and their potential impacts on both human health and the environment. Its 849 pages took seven years to pass, and it has been described as the most complex legislation in the Union's history and the most important in 20 years. It is the strictest law to date regulating chemical substances and will affect industries throughout the world. REACH entered into force on 1 June 2007, with a phased implementation over the next decade. The regulation also established the European Chemicals Agency, which manages the technical, scientific and administrative aspects of REACH. Overview When REACH is fully in force, it will require all companies manufacturing or importing chemical substances into the European Union in quantities of o ...

Legislation
Legislation is the process or result of enrolling, enacting, or promulgating laws by a legislature, parliament, or analogous governing body. Before an item of legislation becomes law it may be known as a bill, and may be broadly referred to as "legislation" while it remains under consideration to distinguish it from other business. Legislation can have many purposes: to regulate, to authorize, to outlaw, to provide (funds), to sanction, to grant, to declare, or to restrict. It may be contrasted with a non-legislative act by an executive or administrative body under the authority of a legislative act. Overview Legislation to design or amend a bill requires identifying a concrete issue in a comprehensive way. When engaging in legislation, drafters and policy-makers must take into consideration the best possible avenues to address problem areas. Possible solutions within bill provisions might involve implementing sanctions, targeting indirect behaviors, authorizing agency ...

100,000,000 Guinea Pigs
''100,000,000 Guinea Pigs: Dangers in Everyday Foods, Drugs, and Cosmetics'' is a book written by Arthur Kallet and F. J. Schlink first released in 1933 by the Vanguard Press and manufactured in the United States of America. Its central argument propounds that the American population is being used as guinea pigs in a giant experiment undertaken by the American producers of food stuffs and patent medicines and the like. Kallet and Schlink premise the book as being "written in the interest of the consumer, who does not yet realize that he is being used as a guinea pig..." Summary The book's key proposition is that a significant portion of the products sold to the public—particularly pharmaceuticals and food products—are released with little regard for or knowledge of how these products adversely affect the consumer. Corporations, often knowingly, release products which either do not do what they purport to do, or have dangerous side effects or defects. Furthermore, many off ...

Dashboard Of Sustainability
The ''Dashboard of Sustainability'' is a free-of-charge, non-commercial software package configured to convey the complex relationships among economic, social, and environmental issues. The software is designed to help developing countries achieve the Millennium Development Goals and work towards sustainable development. The software package was developed by members of the Consultative Group on Sustainable Development Indicators (CGSDI), and has been applied to quite a number of indicator sets, inter alia to the Millennium Development Goals indicators and the United Nations Commission on Sustainable Development indicators. In 2002, Dashboard of Sustainability researchers Jochen Jesinghaus and Peter Hardi presented the Dashboard of Sustainability at the Johannesburg Summit and the 2002 World Social Forum in Porto Alegre.
