Design for environmental processing and manufacturing: Raw material extraction (mining, drilling, etc.), processing (processing reusable materials, metal melting, etc.) and manufacturing are done using materials and processes which are not dangerous to the environment or the employees working on said processes. This includes the minimization of ...
The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa. It is one of several biological wastewater treatment alternatives in secondary treatment , which deals with the removal of biodegradable organic ...
A Sustainable industry would allow for growth in all three deminsions while maintaining the quality of the environment and countering major environmental issues. A report was released in 1987 by the United Nations called Our Common Future in which the concept of sustainable development was listed for the first time along with its guiding ...
Eco-industrial development (EID) is a framework for industry to develop while reducing its impact on the environment. [1] It uses a closed loop production cycle [2] to tackle a broad set of environmental challenges such as soil and water pollution, desertification, species preservation, energy management, by-product synergy, resource efficiency, air quality, etc. [3]
Life cycle assessment is the complete assessment of materials from their extraction, transport, processing, refining, manufacturing, maintenance, use, disposal, reuse and recycle stages. It helps put into perspective whether a design is actually environmentally sustainable in the long run.
It encompasses industries that produce a finished, usable product or are involved in construction. This sector generally takes the output of the primary sector (i.e. raw materials like metals, wood) and creates finished goods suitable for sale to domestic businesses or consumers and for export (via distribution through the tertiary sector ).
Process manufacturing is a branch of manufacturing that is associated with formulas and manufacturing recipes, [1] and can be contrasted with discrete manufacturing, which is concerned with discrete units, bills of materials and the assembly of components. Process manufacturing is also referred to as a 'process industry' which is defined as an ...
The term is usually applied in industrial processes where residue from creating or processing one good is used as a raw material or energy feedstock for another industrial process. [ 61 ] [ 63 ] Industrial wastes in particular are good candidates for valorization because they tend to be more consistent and predictable than other waste, such as ...
