SUMMARY Four aspects of sustainability assessment requiring greater attention and improvement are identified and discussed. These aspects are resource depletion, production scale effects, safety and reliability. LCA methodology is based on inputs as well as outputs. Materials and energy consumption are of key importance from the perspectives of resource depletion, and impacts in resource extrac...

waste is a by-product of our daily activities, which poses a serious threat to societies all over the world. in this study, life cycle assessment (lca) methodology was used to determine municipal solid waste (msw) management strategy for minna, niger state, nigeria. three scenarios were modelled as alternatives to the current waste management system in minna. the baseline scenario was the exist...

Because of the emergence and development of life-cycle assessment (LCA) theory, the concept of building energy efficiency has been re-evaluated. In this paper, leveraged on the advantages and features of BIM and swarm intelligence algorithms, a methodology for the assessment and optimization of BLCEC is proposed to combine the advantage of both paradigms. Based on existing research in optimizat...

Life Cycle Assessment (LCA) has been used to assess the environmental impact of livestock industries since it was adopted as a standard method in 2006. However, many studies have simplified assessment factor for simple assessment. Simplified LCA cannot be business/policy decisions because results can overestimated and underestimated, ignoring interactions between elements. Therefore, is necessa...

Life cycle assessment (LCA) is a method used to quantify the environmental impacts of a product, process, or service across its whole life cycle. One of the problems occurring when the system at hand involves processes delivering more than one valuable output is the apportionment of resource consumption and environmental burdens in the correct proportion amongst the products. The mathematical f...

Goal, Scope and Background. Two methods of simplified LCA were evaluated and compared to the results of a quantitative LCA. These are the Environmentally responsible product assessment matrix developed by Graedel and Allenby and the MECO-method developed in Denmark. Methods. We used these in a case study and compared the results with the results from a quantitative LCA. The evaluation also incl...

The Life Cycle Thinking (LCT) methodologies allow the entire supply chain of wine to be analysed via a systematic approach. Social Organisational Life-Cycle Assessment (SO-LCA) extends product perspective (S-LCA) more complex view organisation, assessing organisation or part it (e.g., facilities, geographical area, brands) from life cycle perspective. It is implemented technical framework adopt...

In recent years, there has been an increasing interest in Life Cycle Assessment (LCA) applied to estimate the cradle-to-grave environmental impact of agricultural products or processes. Furthermore, including in the analysis an economic evaluation, from the perspective of an integrated life cycle approach, appears nowadays as a fundamental improvement. In particular, Life Cycle Costing (LCC), i...

This paper presents the integrating Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) study of the Flue Gas Desulphurization (FGD) system in Fengcheng thermal power plant in China. The FGD systems have been installed in a power generation plant to reduce the large amount of SO2 emission. Studies to appraise FGD system in power plant have mainly focused on economic analysis. This paper gi...

The environmental impacts of global food supply chains are growing with the need for their measurement and management. This paper explores the operations of a global supply chain for extra-virgin olive oil (EVOO) according to a life cycle assessment (LCA) methodology. The LCA assessment methodology is applied to determine the environmental impact categories associated with the bottled EVOO life...
