Uncertainty information is essential for the proper use of LCA in decision making. So far, parameter uncertainty propagation has mainly been studied using Monte-Carlo techniques that are relatively heavy to implement. The consequence is that uncertainty estimates have often been limited to either the inventory part of the analysis or the impact assessment part, very rarely covering the whole LCA. The.. >> more

This work considers a new class of materials known as engineered cementitious composites (ECC) that can enhance the sustainability of bridge, road and pipe infrastructure. It explores impacts on sustainability performance of concrete replacement with ECC, material sourcing alternatives (e.g., superquarries vs. smaller mines), and location of infrastructure projects (e.g., urban vs. rural, and U.S... >> more

The present proposal aims at characterising the human toxicity effects of aluminium-based products in order to improve the reliability of their life cycle impact assessment (LCIA). The present-project aims to develop a detailed case study, applying present LCIA methods to an Aluminium-based product and identifying LCIA weaknesses that need further improvement. It will subsequently propose a framework.. >> more

Using the UNEP-SETAC toxicity model (USEtox), this project aims to recommended and interim characterisation factors for human health and freshwater ecotoxicity impacts. These developments that are essential for an improved comparative assessment of chemicals is carried out in direct collaboration with the model developers of CalTOX, IMPACT 2002, USES-LCA, BETR and EDIP.

We aim to estimate global health impacts of trade by linking three actors: the producers of goods, the consumers of the goods, and the population impacted by the pollution (producers, consumers or a third party). Exchanges through trade (embodied pollution content) and multi-media pollutant transfer are considered on a global scale.

The IMPACT 2002 model provides close to 1000 characterization factors for the midpoint categories human toxicity, aquatic ecotoxicity and terrestrial ecotoxicity for the LCIA methodology IMPACT 2002+. The model is parameterised in a non-spatial and a spatial European model nested in a non-spatial world model, as well as a complete world model.

Creation of an adaptive multimedia model determining intake fractions at local (1km grid around the emission source), regional (200km grid within the continent of emission) and continental (world divided in continents) levels. Special emphasis is given to further develop modeling of exposure in the food chain linked to highest intake fractions and high level of uncertainties. This research builds up.. >> more

Leader: Olivier Jolliet (Ph.D.)
The Impact and Risk Modeling (iMod) laboratory aims to provide the scientific knowledge for assessing environmental risks and impacts of chemicals and of innovative technologies, in order to:
(1) Model population-based exposure and multi-pathways intake fractions for outdoor and indoor chemical emissions
(2) Assess individual and population body burdens and risks using physiologically based pharmacokinetic/dynamic.. >> more
