Life Cycle Assessment (lca) of Nanomaterials: a Comprehensive Approach
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...
متن کاملAn Approach to Treatment of Recycling in Lca Study
As still evolving scientific tool LCA is a subject to a number of problems such as defining system boundaries; allocation of environmental impacts due to making more than one product in the same processes; geographical variations of processes, etc. However, the weakest methodological point in the LCA is an avoided impact. The avoided impacts in LCA occurs when disposal scenarios involve energy ...
متن کاملMapping environmental issues within supply chains: a LCA based approach
This work addresses the optimization of Supply Chain (SC) planning and design considering economical and environmental issues. The SC operations model applied does not require a superstructure definition a priori for the material flows. The strategic decisions considered in the model are facility location and equipment allocation. For the environmental aspects of the problem a Life Cycle Assess...
متن کاملTowards a meaningful assessment of marine ecological impacts in life cycle assessment (LCA).
Human demands on marine resources and space are currently unprecedented and concerns are rising over observed declines in marine biodiversity. A quantitative understanding of the impact of industrial activities on the marine environment is thus essential. Life cycle assessment (LCA) is a widely applied method for quantifying the environmental impact of products and processes. LCA was originally...
متن کاملLCA of PHA Production – Identifying the Ecological Potential of Bio-plastic
The issue of environmental performance of bio-plastics has attracted a large number of researchers over the last two decades. This is a natural result of the fact that bio-plastics have an intrinsic economic disadvantage compared to fossil-based polymers due to higher raw material costs, production processes still in relatively early stages of technical development, and smaller production units...
