Based on information provided by Rodriguez, (Sf), it is necessary to highlight that the main function of the life cycle analysis is to provide information that contributes to the identification of opportunities for improvement, so that they are confronted with those associated risks, and Based on this, make the necessary decisions that lead to improve the performance of the environment. In agreement, the analysis of the life cycle, allows to compare between processes of the same product, or between products of different materials; therefore, this information is applied directly in determining aspects to identify the evaluation and quantification of environmental aspects related to the life cycle, such as the design and development of products, the continuous improvement of processes, planning strategic, green marketing and the development of public policies.

Renewable energies favor the environment positively, since they are a source of clean, inexhaustible and competitively growing energies. In this regard it is known that these are generated through solar panels, wind, etc. According to Hansia, Xiongwenb, Xunmina, (2016), renewable energy is capable of developing in the future. Regarding the Distributed Energy System project based on solar energy, it should be noted that this has a positive but limited effect on energy saving and emission reduction. It is limited by solar resources in Sichuan province.

According to ISO 14040 and 14044, in an ACV study there are 4 phases, which are important to mention, such as:
Definition of objectives and scopes: This explains the reasons why the study is developed. Here, aspects such as the breadth, depth and detail of the study are defined.
Inventory of the Life Cycle (ICV): In this phase, specific aspects that can cause an impact during the life cycle of a product are identified and quantified.
Life Cycle Impact Assessment (EICV): The purpose in this phase is to classify, characterize and assess the importance generated by the potential impacts
Interpretation of results: In this phase an interpretation is made that combines the results of the (ICV) and the (EICV); with the purpose of displaying conclusions and recommendations that facilitate decision making. Rodriguez (Sf)

In the article, the life cycle analysis method (LCA) is used to evaluate the energy consumption and greenhouse gases, where the Natural Gas Distributed Energy System Project is analyzed, and compared with other 5 cases with different energies such as coal, its energy consumption and emissions performance. Projects based on renewable energies are analyzed differently, since costs and fuel emissions are considerably small in renewable technology. Energy, consumption and emissions during life cycle processes should not be neglected, therefore, the life cycle analysis (LCA) method is frequently used to analyze projects based on renewable energies since Results provide a solid basis for future research in this field. We could also show that renewable energy projects have the potential to develop in the future, so policymakers should support the development of gas from distributed energy systems projects and additional research should be done to make better decisions about the use of clean energies

The life cycle analysis is an environmental assessment methodology, through which all aspects of environmental matters can be analyzed and quantified. This study includes all the stages of its existence, that is, it takes into account aspects from the extraction and processing of raw materials, their manufacture, transportation, distribution, use, reuse or recycling; as well as the final disposal of the waste of a product, process or service throughout its life cycle.

Due to the environment where the project was carried out, solar energy can hardly improve the performance. However, it is possible to use biomass (byproduct of beer production) or wind energy in the distance to improve the system.

We can conclude that, solar energy and biomass, can meet part of the demand for electricity, these energy models to generate low costs and emissions can be beneficial for society and the environment. For example, Biomass energy can save energy consumption of the life cycle by 31% compared to the case of coal; Wind energy significantly reduces energy consumption and GHG emissions (35% and 35% respectively) compared to all coal.

En otras ocasiones hemos hablado del Análisis del Ciclo de Vida (ACV) desde el punto de vista de definición y aplicaciones. Sin embargo, cuando queremos avanzar en la implantación de estas herramientas siempre es recomendable apoyarse en marcos normativos y metodológicos.

El conjunto de normas que regula la aplicación de la metodología del Análisis de Ciclo de Vida (ACV) fue preparado por el Comité Técnico ISO/TC 207, Gestión Ambiental, Subcomité SC 5, Análisis de Ciclo de Vida.

Dicho comité ha generado las siguientes normas:

ISO 14040:2006 Gestión Ambiental. Evaluación del ciclo de vida. Principios y marco

La norma ISO 14040:2006 describe los principios y el marco de referencia del ACV entre los que se encuentran: la definición del objetivo y el alcance, el análisis del inventario del ciclo de vida (ICV), la fase de evaluación del impacto del ciclo de vida, el informe y la revisión crítica, limitaciones y la relación entre las fases del ACV.

Esta norma no especifica metodología para las fases individuales de ACV.

ISO 14044:2006 Gestión Ambiental. Evaluación del ciclo de vida. Requisitos y directrices

La norma ISO 14044:2006 especifica los requisitos y ofrece directrices concretas para la realización de un ACV entre los que se encuentran: l a definición del objetivo y el alcance del ACV, el análisis del inventario del ciclo de vida (ICV), la fase de evaluación del impacto de ciclo de vida (EICV), la fase de interpretación del ciclo de vida, el informe final y la revisión crítica.

Esta norma junto con la antes citada ISO 14040:2006, anulan y reemplazan a las normas ISO 14041:1998, ISO 14042:2000 e ISO 14043:2000 que han sido revisadas técnicamente dando lugar a los siguientes informes técnicos:

ISO/TR 14047:2003 Gestión Ambiental. Evaluación del impacto del ciclo de vida. Ejemplos de la aplicación de la norma ISO 14042

La norma ISO/TR 14047:2003 proporciona ejemplos que ilustran las prácticas habituales a la hora de llevar a cabo la evaluación del impacto del ciclo de vida (EICV) según la norma ISO 14042.

Únicamente proporciona algunos ejemplos entre todas las maneras posibles de cumplir con las disposiciones de la ISO 14042. Reflejan los elementos clave de la evaluación del impacto del ciclo de vida (EICV).

Los ejemplos presentados en la ISO/TR 14047:2003 no son exclusivos, hay multitud de maneras para ilustrar los asuntos del tipo metodológico descritos.

ISO/TR 14048:2002 Gestión Ambiental. Análisis de ciclo de vida. Formato de la documentación de datos

Esta especificación técnica proporciona requisitos así como una estructura de formato de datos necesaria para conseguir que la documentación resulte transparente e inequívoca a la hora de presentar datos relativos al ACV y al inventario del ciclo de vida (ICV).

Proporciona especificaciones para que la documentación de datos sea coherente durante la recopilación de los mismos, el cálculo de éstos y su calidad final.

ISO/TR 14029:2000 Gestión Ambiental. Análisis del ciclo de vida. Ejemplos de aplicación de la ISO 14041 para la definición de objetivo y alcance y el análisis de inventario

Ya terminamos :-) ... Es una especificación que proporciona ejemplos en la definición de los objetivos y alcances así como en el análisis de inventario de ciclo de vida en los estudios de ACV.
Esperamos que os haya resultado de interés este artículo. Un poco de contenido técnico de vez en cuando no viene mal ¿no crees?
