Design for environment:- an engineering perspective in which environmentally related characteristics of a product, process or facility design are optimized.
Eco-efficiency:- a business strategy to produce goods with lower use of materials and energy to realize economic benefits of environmental improvements
Industrial ecology:- An approach to the design of industrial products and processes that evaluates such activities through the dual perspective of product competitiveness and environmental interactions.
Industrial symbiosis:- A relationship within which at least two willing industrial facilities exchange materials, energy, or information in a mutually beneficial manner.
Industrial metabolism:- a concept to emulate flows of material and energy in industrial activities from a biological systems perspective.
Life cycle assessment:- A concept and methodology to evaluate the environmental effects of a product or activity holistically, by analyzing the entire life cycle of a particular material, process, product, technology,service or activity. The life cycle assessment consists of three complementary components. (1) Goal and scope definition (2) inventory analysis, and (3) impact analysis, together with an integrative procedure known as improvement analysis.
Material flow analysis:- An analysis of flow of materials within and across the boundaries of a particular geographical region.
Pollution Prevention:- The design or operation of a process or item of equipment so as to minimize environmental impacts.
Recycling:- The reclamation and reuse of output or discard material streams for application in products.
Remanufacture: - the process of bringing large amount of similar products together for the purpose disassembly, evaluation, renovation and reuse.
DEFINING INDUSTRIAL ECOLOGY
Industrial ecology is industrial in that it focuses on product design and manufacturing processes. It views firms as agents for
