Agriculture is a major driver of sustainable development in developing countries. However, with the increase in the global population, the amount of waste generated by agriculture has also increased, leading to environmental pollution. The increase in agricultural activity is proportional to the...

Throughout the various stages of the life cycle of a building, a significant amount of CO2 is released into the atmosphere: in the production of goods and materials, the construction of the building itself, the preparation of the site, the exploitation, the repairs, the subsequent rehabilitations...

A comparative economic and life cycle based analysis of five management scenarios for the solid waste generated in the island of Syros was conducted. The LCA part was performed with the LCA – IWM software. The four on-site waste management scenarios were: i) source separation of recyclable materials...

This work employs the environmental methodology of Life Cycle Assessment (LCA) in compliance with ISO 14040 and uses software SimaPro® 7.3.2 to compare the environmental impact in process production of flat plate and evacuated tube solar collectors. In addition, an economic analysis was performed...

The aim of this work is to quantify the life-cycle emissions in terms of CO 2 equivalent grams per megajoule of biodiesel produced from Acrocomia totai, a native oily seed from Paraguay, according to Directive 2009/28/EC. The other key point is to calculate the amount of energy invested to get a...

Natural systems offer an economic solution for the treatment of wastewater from small settlements. This study presents a detailed technical analysis of three stabilization pond systems designed to treat municipal wastewater, varying in capacity from 250 to 1400 population equivalent. Construction...

Improving the treatment efficiency of a primary wastewater treatment plant(WWTP),in Alexandria, Egypt,was studied.In order to improve the treatment efficiency of the plant, different improving scenarios were proposed and evaluated. The improvement scenarios are: scenario 1,use of engineered wetland...

In recent years, a considerable research effort has been devoted to Life-Cycle Assessment (LCA). However, most of the work has been focusing on improving the methodology as such and providing guidelines for carrying out LCA studies. Much less effort has been dedicated to the exploration and analysis...

Life cycle assessment (LCA) is a technique for holistic environmental assessments of products and processes. The unique feature of this methodology is its focus on the entire life cycle of a product, from raw material extraction to final disposition. In order to assess the role of LCA in...

Life Cycle Analysis (LCA) is a procedure used as an analytical tool for the evaluation of the environmental impact caused by a material, a manufacturing process or product. For an end product, LCA requires both the identification and quantification of materials and energy used in all stages of the...
