2018年6月1日 · What is 'cut-off' when creatinging a new product system? How does a cut-off criteria affect the creation of a product system? The use of cut-off reduces the required memory of openLCA and the calculation time. Unfortunately, (and not surprisingly) this goes along with a loss of detail in the results.

In this section, we provide an overview of openLCA's key features by demonstrating a typical LCA modeling approach. These key elements include selecting a background database, creating processes and products, connecting them to a life cycle, choosing an impact assessment method, performing life cycle calculations, and reviewing the results.

2024年1月1日 · Cut-off model is based on the recycled content or cut-off approach. In this system model, wastes are the producer’s responsibility (“polluter pays”), and there is an incentive to use recyclable products that are available burden free (“cut-off”).

In the Life Cycle Impact Assessment (LCIA) phase, LCI results are associated to environmental impact categories and indicators. This is done through LCIA methods which firstly classify emissions into impact categories and secondly characterize them to common units so as to allow comparison (details on the LCIA are presented in the section below).

2019年2月6日 · I'm rather new in LCA, and am struggling to understand the differences between the different system models (APOS, cut-off and consequential). I have read their definitions in Ecoinvent database, but still don't know which method to choose under each scenario. Could anyone provide me with an example of when it is recommended each of the methods?

Provide up-to-date information to serve the demand of LCA data in downstream market and help the industry and stakeholders better understand the potential environmental impact of aluminum products. Product systems include primary aluminum, recycled aluminum, and semi-fabricated aluminum (extruded, rolled and casted).

2024年11月13日 · 生命周期评估 (LCA) 已成为评估产品和流程的环境足迹不可或缺的工具。LCA 软件的选择会显著影响分析的准确性、效率和深度。这篇博文将探讨三种流行的选择：LCA for Experts（以前称为“GaBi”）、SimaPro 和 OpenLCA。 专家级生命周期评价 (GaBi)

生命周期评价 (Life cycle assessment, LCA)是一种评价产品、工艺或服务从原材料采集到产品生产、运输、使用及最终处置整个生命周期阶段(从摇篮到坟墓)的能源消耗及环境影响的工具。LCA方法始于20世纪70年代。

2024年11月13日 · Life Cycle Assessment (LCA) has become an indispensable tool for evaluating the environmental footprint of products and processes. The choice of LCA software significantly impacts your analysis’s accuracy, efficiency, and depth. This blog post will explore three popular options: LCA for Experts (formerly “GaBi”), SimaPro, and OpenLCA.

LCA is a systematic procedure which assesses the lifecycle of a product to analyze the extent of its environmental impact contribution. In this LCA study comparison between three different water...
