NORM TECHNICAL COLOMBIAN NTC - ISO 14040

This standard was created for environmental protection and the possible associated impacts that a product can generate. That is why it is interesting to develop methods to understand and deal with those impacts.

The life cycle can help us to identify the possible damage that the production of a product can cause to the environment.

It also helps us to study each product and reduce as much as possible the agents that generate pollution

DESCRIPTION OF THE LIFE CYCLE ANALYSIS

The complete cycle of a product is considered from its extraction and acquisition of the raw material, through the consumption of energy and material, to the use and final treatment of the useful life and the final disposal of the waste generated in the process. Through this study, a potential environmental burden can be avoided between the stages of the life cycle.

This study deals with the aspects and impacts of a product system. The analysis of the life cycle is structured in a functional unit that defines what is being studied since all the inputs and outputs are related in the ICV. In a LCA, transparency must be taken into account to ensure an adequate interpretation of the results. For a good LCA, all the attributes of the natural environment, human health and resources must be considered to evaluate the potential compensations.

Life Cycle Analysis of Distributed Energy

The life cycle is used in the areas where a plan is made to be able to specify an objective in this case the consumption of energy and greenhouse gases.

Currently, sources of energy generation have become a problem for many people on the planet.

The projects of energy systems and greenhouse gas emissions in China reduce the loss of efficiency during energy transport. From the point of view of the environment, the life cycle is a concept that allows measuring the environmental impact of a product since its raw materials are extracted from nature until it returns as a waste.

This report takes into account the entire chain of energy production from exploration and extraction to processing, storage, transport, transformation into secondary fuels and final use. Hence, the report considers each primary energy according to its point of origin and its final use. It provides the CME members and the international community with a comparison of the different energies based on the complete life cycle assessments that have been carried out in recent years.

The evaluation of the life cycle of emissions from energy production and transport has been the main objective of studies due to international conventions for the control of emissions and the direct and indirect impacts on health and the environment.

For life cycle assessments of energy production, other factors related to the rational use of energy, natural resources and land have also been considered. This kind of analysis has been used to compare the cycles of renewable and fossil energy among themselves

Since many renewable energies (particularly solar and wind) are "diluted", more materials and larger areas are needed than for fossil fuels.

In the article of the cycle of the life the consumption of energy in the effects of her is defined, to maintain or to accept the breweries of china and the formulation of the cases with not similar energies

Renewable energies have become an unbearable contribution in the generation of current electric power, making a gap between conventional technologies. Once installed they fulfill the objective of zero emissions of polluting gases, but the process of manufacturing their components together with their construction is not

. taken into account, for this reason a life cycle analysis has been used to know the environmental impact that will allow know the CO2 emissions, consumption of water resources or environmental toxicity.

The analysis of the life cycle of a product is a methodology that attempts to identify, quantify and characterize the different potential environmental impacts associated with each of the stages of the life cycle. The methodology considers a series of interrelated work phases that follow a more or less defined consequence.

The sustainable use of water resources in the energy industry based on the evaluation of the water footprint in the province of HUNAN, the main problems that must be addressed is the management of natural resources in the shortages of energy and fresh water. As well as the scarcity of water resources due to the high pollution in

As the problem of global warming becomes increasingly serious, countries strive to develop a rapid economic expansion and bring a remarkable increase in energy consumption, strive to develop renewable energy, this being a priority, making great efforts for reducing the consumption of coal products

The amounts of CO2 emitted by each process are analyzed to know their impact on global warming. This data is especially interesting since the use of the solar resource is a renewable energy.

There are four phases in a HCV study according to ISO 14040

Definition of objectives and scope: The reasons for which the study is developed and the scope where the amplitude is defined are stated.

Inventory of the life cycle (ICV): In this stage all the stages (consumption of resources and materials) and salinity (air emissions) soil, water and waste regeneration that can cause an impact during the life cycle are identified and quantified of a 

product.Evaluation of the impacts of the life cycle: The inputs and outputs selected in the inventory are related to the possible impacts on the environment

nterpretation of results: It is the convincing of the results of the (ICV) and the (EICV) in order to extract from sane to the objectives and scope raised where the holistic approach to life cycle analysis is equally applicable to everyday life and They help us to recognize the way in which our actions are part of a great system of acts

NTC ISO 14040 deals with the evaluation of the possible impacts associated to the products from the purchase of the inputs to manufacture them, as well as in the stage of consumption of this and the stage of its final disposal, for this reason the life cycle allows to identify methods in which the negative environmental impact can be reduced when developing a product.

Within the application of the life cycle analysis there are 4 phases:
Phase of definition of the objective and scope,
The inventory analysis phase,
The environmental impact assessment phase, and
The interpretation phase.

This international standard covers two types of study: Analysis

of the life cycle and analysis of inventories of the life cycle.

Some relevant terms and definitions are:

3.1. Life cycle: Consecutive and interrelated stages of a product system, from the acquisition of raw material or its generation from natural resources to the final disposal.

3.2 Life cycle analysis. (ACV) Compilation and evaluation of inputs, outputs and potential environmental impacts of a product system through its life cycle.

3.3. Inventory analysis of the life cycle. (ICV). Phase of the life cycle analysis that involves the collection and quantification of inputs and outputs for a product system through its life cycle.

3.4. Impact assessment of the life cycle. (EICV). Phase of life cycle analysis aimed at knowing and evaluating the magnitude and how significant are the potential environmental impacts of a product system throughout the life cycle of the product.

Sandra Carolina Vega What life cycle analysis is about

sacavega8 — 2019-04-21 17:59:18 UTC

El ACV aborda los aspectos ambientales y los efectos del sistema de producto. Los aspectos e impactos económicos y sociales generalmente están más allá del alcance del ACV.

Las características esenciales de un ACV:

El ACV evalúa sistemáticamente los aspectos de los sistemas de los productos, de la adquisición de la materia prima hasta la disposición final, de acuerdo con el objetivo y el alcance establecido.

La naturaleza relativa de un ACV es debida a las características de la unidad funcional dentro de la metodología;

El nivel de detalle y la duración de un golpe puede variar, los resultados de la definición del objetivo y el alcance;

Se verán las disposiciones, según la aplicación prevista de la LCA, para respetar la confidencialidad y la propiedad;

La metodología LCA está abierta a la inclusión de nuevos descubrimientos, mejoras y mejoras en el estado del arte de la técnica;

Los requisitos específicos se aplican al ACV que se intenta utilizar a las afirmaciones comparativas que se divulgan al público;

Los flujos primarios incluyen la utilización de los recursos y las emisiones en el aire, y las descargas de la tierra y el agua en el sistema.

Sandra Carolina Vega Requirements and guidelines in life cycle analysis

In the practice of LCA, several cutting criteria are used to decide which inputs are included in the evaluation, such as mass, energy and environmental importance.

It is useful to describe the system using a process flow diagram that shows the unit processes and their interrelationships. Initially each of the unit processes should be described to define:
Where the unitary process begins in terms of the reception of raw materials or intermediate products,
The nature of the transformations and operations that occur as part of the unitary process, and
Where the unitary process ends in terms of the destination of the intermediate or final products.
