Background: Due to the lack of a proper waste management system, Tehran Municipality Region 20 is facing economic and environmental problems such as the high costs of a disposal system and source pollution. Life cycle assessment (LCA) is a method for collecting and evaluating the inputs, outputs, and potential environmental impacts of a product system throughout its life cycle. The current stud...

Life cycle assessment (LCA) applications within large European firms are discussed. Many industrial applications have been proposed for cradle to grave assessments of environmental burdens of products, including technology design and optimization, technology strategy, green marketing and environmental foresight. There is evidence of a growth of LCA competences and applications within industrial...

Life cycle assessment (LCA) has become the prevalent approach for quantifying the environmental impact of products over their entire life cycle. Unfortunately, LCA studies require large amounts of data that are difficult to collect in practice, which makes them expensive and time consuming. This work introduces a method that simplifies standard LCA studies by using proxy metrics that are identi...

One of the main fortes of emergy analysis is its ability to account for the contribution of ecosystem goods and services, or natural capital. Other holistic analysis methods including life cycle assessment, energy and exergy analysis have ignored this crucial contribution from nature, which is the very basis of sustainability. We introduce a novel approach for an Ecologically-Based Life Cycle A...

The need for more sustainable products and processes has triggered the development of a large number of environmental assessment tools. These tools measure environmental performance and identify improvement potentials from the environmental point of view. The life cycle assessment (lca) methods take into account all effects on the environment, direct and indirect resource inputs and/or emission...

LCA is a suitable method to assess the environmental performance of nanotechnology-based products, although challenges remain due to uncertainties and data gaps. LEITAT participates in different European projects, such as NANOMICEX, NANOPOLYTOX, NEXTEC, EUROTAPES and NANOSOLUTIONS, which contribute in filling in these gaps. Selected representative nanotechnology-based products were modelled, in...

Purpose The purposes of this commentary are to further an on-going debate concerning the appropriate form of land use baseline for attributional life cycle assessment (LCA) and to respond to a number of arguments advanced by Soimakallio (Int J Life Cycle Assess 20:1364–1375, 2016). The commentary also seeks to clarify the conceptual nature of attributional LCA. Methods The overarching approach ...

This thesis is part of a larger project which began in response to a request by the Spanish water agengy, Cadagua, for advice on life cycle assessment (LCA) and environmental impacts of Cadagua operated wastewater treatment plants. The project uses the LCA software GaBi and focuses on La Gavia Wastewater Treatment Plant in Madrid. This thesis analyzes three sludge management options that La Gav...

Nacrtak Environmentally sound technologies are a key to reduce resource use and environmental impact. The paper reviews the state of knowledge of an analysis tool, life cycle assessment (LCA), by addressing three issues: 1) methodological foundations of LCA, 2) lifecycle inven­ tory modeling, and 3) environmental performance indicators for wood supply systems. The study results in the following...
