Some definitions

Environmental engineering

Environmental engineering is the branch of engineering that studies problems related to the Earth in a scientific and integrated way, considering its scientific dimensions: chemical, physical, ecological, biological, geological, social, economic and technological, with the objective to promote sustainable development.

It is a branch of environmental sciences based on the creation, application and management of technological procedures, products and services intended for the prevention, control and remedy of environmental problems; to the development of the sustainable use of natural resources in production and consumption processes, having as a priority the improvement of the quality of life with the preservation of natural resources.

Environmental engineering contributes to guaranteeing, through the conservation and preservation of natural resources, a better quality of life for the current generation and for future generations.

Life cycle analysis

Life cycle analysis (LCA) is a method for carrying out a multi-criteria and multi-stage environmental assessment of a system over its entire life cycle.

Its purpose is to know and be able to compare the environmental impacts of a system throughout its life cycle, from the extraction of the raw materials necessary for its manufacture to its end-of-life treatment (disposal of waste, recycling, etc.), through its phases of use, maintenance and transport.
