Tutorial: How to analyse LCA results in openLCA (Part 2)

[@jonsjoy1265]

Thank you for the explanation

[@kamelzidani2499]

Thank you very much for this very instructive presentation.

[@bintoukonate8052]

Thank you very much, the tutorial is very easy to understand.

[@boor82]

Thank you for the explanation. I would like to ask you why, even though, in the comparison, you changed the oil ammount for the production, the results show exactly impatct ten times higher for the production of ten kilos of chicken pasta? The Oil quantitative seems not to influence the results, which are onl affected by the quantitative of chicken pasta producted

Mam can you please provide a openLCA tutorial for life cycle assessment of concrete and which database is used for concrete material.

[@FahadMacarandas]

very informative why my calculation properties don't have analysis option as shown in your tutorial? I am using the latest version anyway.

[@amy-g.]

Thank you for the insights! Would like to ask where to find the "global warming" selection in the "impact category" in version openLCA 2.0.0? There are only "water ecotoxity, human cancer toxity and human non toxic

[@PriyaKumari-gx9gt]

Thank you for the video. i actally had a query. I am unable to import database into existing Database. My existing database is ecoinvent 3.5 and imported database is openLCA LCIA Methods v2.0.2. How do i further proceed?

[@lookingforgoal2077]

for sand casting process which database we should use?

[@mustafaali5222]

Hi. Can you specify system boundaries and compare impacts from different parts of the supply chain, for instance (a) cradle to gate with (b) farm gate to retail and (c) retail to grave and so on....

[@openLCA]

Yes this is possible in openLCA. We keep this in mind for future case studies that we will publish. As a teaser we can say that we are working on one case study on dental floss.

[@dilmonouseph]

Hi, i need to know how to add various substrates, manufacturing processes and its amounts manually to this software? If you have mentioned it anywhere, please specify that part ?

[@mmehdi3437]

Great video

[@parthbhatia2478]

Thanks for such an insightful video! Would like to ask you where can I see the GHG emissions generated during the entire life cycle of the pasta preparation?

[@openLCA]

Thank you for your comment. Once you have calculated results, you can see them in the third tab "Impact Analysis".

[@nkyibe1299]

Thanks for this video But please can you use a building construction for an example??

[@user-mc6eq7hz6q]

Hello I have a naive question. I was following the steps to get the report, with 50g olive oil for 10 kg pasta and 10g olive oil for 1 kg pasta. The numbers I have produced for 10 kg are not 10 times of the 1 kg pasta. Could you please explain? Thanks.

[@louvre266]

Thank you very much 😊

[@leilanattagh8015]

How do we capture the impact of the Mediterranean spices?

[@openLCA]

In this case, you need to create a process which describes the production of this flow (Mediterranean spices) then you will be able to see its impact in the process results, contribution tree, Sankey diagram etc) by changing the required impact category!

thank you so much!!

Hi. What kind of database should I download if I want to use the Environmental Product Declaration (EPD) method for waste disposal LCA?

[@nesyajuliana3608]

anyone knows why i can't see the LCIA Method option when doing the comparison?

[@kamelzidani2499]

if possible where to find your other presentations. Thank you

[@Nomaj1507]

Hi! Is there any material regarding Hot Mix Asphalt LCA analysis on OpenLCA?

[@portland_russ]

I still don't get it. The ReCiPe point for, in this case, Chicken pasta, must be one quantitative value, for example, 0.5 Pt/kg. Then we calculate with the same method, for example, Fried fish, we get, say, 5 Pt/kg, and clearly see the difference. The result must be self-explanatory. Here the result contains multiple options and it's not obvious which one I should choose for further calculations. Simply put, I need a total single score.

[@QmrZaib]

Very helpful

[@Gokul-ok9dk]

hi bro can you help me to do this project. i hve some doubt in analysis.

[@jigiRocksify]

Thanks for the complete explanation, Few of my queries are... 1. Normalization and weighing methods are not showing in my software,( I'm using the student version of ecoinvent 371 database and ecoinvent 37 lcia methods) 2. There are not any single score indicator results when I compare two product systems 3. When I select result analysis tab for calculating the results for product system, after too much time it shows a pop-up windo demanding more memory and then I allocate more memory in files>configuration, again same error!

[@moxopal5681]

How did you manage to get the free licence of ecoinvent? I cant find it for free

[@piapsalm7669]

hello do you have videos LCA of microplastics?

[@dhawalbharitkar1601]

Hi, too much time taken to import th lcia database into agribalyse database. pls. let me know the reason.

[@openLCA]

This depends on the hard disc speed, with an SSD it is less than 30 minutes

[@tradervale2876]

how to calculate indicators? from the impact categories..example if I want to calculate freshwater use from the whole product system

[@openLCA]

By using a water impact method (if this was your question?)

[@tradervale2876]

@@openLCA yes..thank you

can someone help me with robotic mig welding vs robotic laser welding?

[@sharonthomsonATR]

Hi, thank you for this video it was very to understand. May I know how can we do comparisons of different product material through cradle to grave using OpenLCA. What type of database is normally used to analyze packaging materials? Thank you, desperately need help on this!

[@openLCA]

Thank you for your comment. Indeed you can compare different products by creating a Project in openLCA. There, one can compare Product Systems, which would hold the environmental impacts of the product under consideration. There is even the possibility to play with Parameters here. Regarding the database, the most important thing here is that your database covers the background data that you require. You can check the different databases we provide and the focus topic here: nexus.openlca.org/databases

why my results not same s urs even tho i follwed exact

how to resolve ..failed to write openlca.ini file error.....while calculating results

Please have a look at this explanation, it might help! ask.openlca.org/852/error-failed-to-write-openlca-ini-file

[@zhou1774]

Hello, where is the result of different amounts of olive_oil?

[@openLCA]

Hi! the results sum up the different amounts of olive oil and pasta together. If you would like to see specifically the olive oil effect, then you may fix the same target amount of pasta but only change the olive oil parameter value !
