Goal And Scope

A huge number of available Life Cycle Assessment (LCA) studies have shown that data availability for paper products is enormous regionally. In Malaysia, LCA practices are considered uncommon attributed to the lack of data availability and LCA practitioner itself. Therefore, a cradle to cradle study has been carried out to determine the potential impacts arise from the recycled paper production in Malaysia. LCA methodology used in this study including goal and scope definition, inventory analysis (LCI), impact assessment (LCIA) and interpretation is based on ISO 14040 and ISO 14044 framework. A series of input-output data collection has been carried out and the collected data was calculated by using Simapro software followed by data evaluation using Eco-indicator 99 method. The results showed that the most significant impacts generated throughout the system were fossil fuel and resources at the midpoint and endpoint level respectively. This can be attributed to a high consumption of chemicals and energy in the pulp and paper manufacturing process. As a consequence, a comprehensive practice in mill specifically on chemicals and resources include water and energy consumption, as well as the waste management and recycling system needs to be addressed explicitly to mitigate the relevant impacts.

Goal And Scope Definition

AbstractIn 2013 the population of dairy cattle in Indonesia had reached 636,000 head with a 4.61% growth rate per year. The inputs were energy, water, and feed. These inputs produced outputs, such as emissions, solid waste and liquid waste. This research compared the maintenance systems in modern farms and local farms. The data were collected from 30 local farmers and one modern farm. This research used the life cycle assessment (LCA) method. LCA is based on ISO 14040. LCA consists of several stages: the goal and scope definition, inventory analysis, impact assessment, and interpretation. This research used the cradle to gate concept and fat corrected milk (FCM) as the function unit. The impacts of these activities could generate global warming potential (GWP), acidification potential (AP), and eutrophication potential (EP). The calculations showed that the systems in local farms had the greatest emissions result over all impacts. In the case of local farms, the GWP was 2.34 kg CO

Los procesos de generación de electricidad a partir de combustibles fósiles son fuentes de contaminación ambiental, siendo una preocupación actual de los países en desarrollo. El objetivo del presente trabajo fue evaluar el impacto ambiental de la generación distribuida de electricidad en una central de 110 kV por medio del Análisis del Ciclo de Vida para la determinación de mejoras en el proceso. El Análisis del Ciclo de Vida (ACV) se realiza de acuerdo con los requisitos establecidos en la NC ISO 14040: 2009, utilizando el Eco-indicador 99 del software Sima Pro 7.1. Los impactos ambientales se evalúan a partir de un análisis de inventario en cada una de las etapas del proceso, contabilizando las entradas y salidas de materias primas, energía y emisiones al aire, agua y suelo, para lo cual se realiza un diagrama de flujo del proceso. A partir del análisis de los flujos, se determinó que los parámetros condenatorios en el caso de los efluentes, sólo se cumple para el pH y la conductividad eléctrica, en el caso de las emisiones al aire se viola con el NO2 y SO2. Los resultados muestran que la etapa de mayor contribución se concentra en el área de generación y los productos más agresivos al ambiente son el consumo de fuel oil (80 % para la salud humana, 53 % para el ecosistema y para los recursos naturales 95 %) y el producto residual de la limpieza de los materiales de explotación (en el caso del ecosistema 35 %). Abstract The electricity generation process from fossil fuels its source of environmental pollution, being a current concern at developing countries. The objective of the present work was to evaluate the environmental impact of the distributed electricity generation in an 110 kV oil fuel power station using the Life Cycle Assessment method to determinate improvements in the process. The Life Cycle Assessment (LCA) was perform according to the requirements established in the NC ISO 14040: 2009, using Eco-indicator 99 with software Sima Pro 7.1. The environmental impacts were evaluate starting from an inventory analysis in each stage of the process, accounting the inputs and outputs of raw materials, energy and emissions to the air, water and soil; a flow diagram of the process was generated for the assessment.  From the analysis of the flows, it was determined that the condemnatory parameters in the case of effluents, is only met for the pH and electrical conductivity, in the case of air emissions is violated with on the NO2 and SO2. The results, show that the stage with the greatest contribution is concentrated in the generation area, and the most aggressive products to the environment are the consumption of fuel oil (human health 80 %, ecosystem 53 % and natural resources 95 %) and the residual product of the cleaning of the exploitation materials (35 % in the case of the ecosystem).

The disposal of the drill cuttings is a complex environmental problem. In the paper, two offshore drill cuttings management options are evaluated using life cycle inventory analysis, namely offshore reinjection and onshore solidification. Environmental burdens of the two management options are calculated. Results indicated that: a) From the life cycle perspective, treating 1 m3 drill cuttings, onshore solidification generate more CO2, CO, NOx, COD, TOC and Ammonia nitrogen than reinjection. On the contrary, reinjection generate more PM 2.5, PM10, SOx, Nitrate, and SS than solidification. Which option has less environmental impact needs further assessment. b) Selecting an environment-friendly curing agent is necessary for solidification process to reduce CO2 emissions.
