Compared to PET cups, the current PLA cups offer environmental impact savings for climate change even including the impacts of LUC.

This makes openLCA very suited for research.
#Displacement allocation openlca software#
At the same time, openLCA is a user-friendly software users are not forced to work with a nerdy command-line for example. LUCs contribute to a negligible impact in all impact categories except for climate change and photochemical ozone formation. openLCA provides features and possibilities not available in other LCA software and it can be extended to meet and include specific new approaches. It was found that the biomass acquisition phase has a limited overall impact. For PLA cups, the process energy use in the conversion from biomass to PLA polymer was identified as the main environmental hotspot, followed by the electricity consumption of thermoforming of the cups. State of Indiana 2022 Qualified Allocation Plan Section 3 - Private Activity Tax-Exempt Bond Financing Developments applying for 4 RHTC and tax-exempt bonds must satisfy and comply with all requirements for an allocation under this Allocation Plan and the Code. Based on the available data quality of the petrochemical polymers, six impact categories were compared. When calculating the LCI and LCIA results the preferred allocation method can be selected in the calculation settings. PLA cups were then compared with their petrochemical counterparts polyethylene terephthalate (PET) and polypropylene (PP) cups. In openLCA there are three allocation methods: Every process has an Allocation tab where the allocation factors for all three cases can be viewed or altered. 2.818 Freshwater ecotoxicity CTUe 17.217 Freshwater eutrophication kg P eq.

OpenLCA 1.7 ReCiPe (H) mid-point indicators 9. The manufacturing phase was modeled based on primary production data stemming directly from the industry. Land use changes (LUCs) were assessed based on a deterministic model. AI represents the absolute environmental impacts (i.e., before allocation) from completing a life cycle stage once. Under the context of the recent EU Plastics and Bioeconomy strategies, this study uses life cycle assessment (LCA) to assess the environmental footprint of single-use drinking cups made from PLA, including 13 environmental impact categories. The allocation fraction (A f) is the fraction of impact of a life cycle stage which is allocated to the material in the use cycle of the assessed building component. This information is important to LCA practitioners, as it can often tip the balance between two compared alternative products or materials.Polylactide (PLA) is both bio‐based and biodegradable and has therefore attracted increased attention for single-use plastics applications. However, accurate information on the displacement rates of various materials is largely unknown. In case studies, practitioners typically utilize heuristic, arbitrary rules, such as assigning 100%, 50%, or 0% displacement of virgin material by recycled material. is not only impossible with economic allocation to select. The extent to which recycled material displaces production of virgin material of a similar or different type is the subject of current research. A life cycle assessment (LCA) with a normalization step was conducted for perennial crops to.

This credit is termed "avoided burden" because it refers to the impact of virgin material production that is avoided by the use of recycled material. attributional models, this will affect the results if economic allocation is applied.

For instance, PET bottles may be given environmental credit for the PET they contain, as this material will eventually be recycled back into further PET products. When determining the overall environmental impact of a product, the product is given "credit" for the potential recycled material included. Avoided burden is an approach used in life-cycle assessment (LCA), especially in the context of allocating environmental burden in the presence of recycling or reuse.
