Re: recycling plastics

I'm sorry for my "late" reply but I thank you all for your answers! In the end of my work about beer bottle I excluded the impacts related to the plastic fraction recycled; I assumed that the other fraction is treated through incineration and landifilling. Thanks for the pdf document that you shared...

Re: Import lcafood database

Hi Andreas, how are you? I'm about to run a Carbon Footprint studt for professional purpose and I've just found this old post of yours with LCA FOOD converted into zolca files. I think this is very useful, but I would need some further explanation. Can I use this converted database with openLCA impa...

recycling plastics

Hi everybody, I'm running a LCA study and I have to model the end of life stage of a beer bottle. I cannot find in the ecoinvent 3.1 any activity like, for exemple, "treatment of plastic, post-consumer..." or something like these. Can you help me or, at least, can you tell me why such activities are...

Re: negative values among the inventory inputs

Hi Andreas, I checked the system and here are some considerations. I didn't put any avoided products in my processes and all the water inputs in the whole system seem to be positive. Through the analysis tool in openLCA I saw that the negative values are related to fertiliser production, that is rel...

Re: negative values among the inventory inputs

I forgot: my reference process has only one product that is 1 kg of onions and no emissions or waste because they are already included in the inputs processes.

Re: negative values among the inventory inputs

Hi Andreas, I did the following: 1. I chose some processes in agricultural means of production category (such as irrigating, sowing, tillage, ecc.) and I made copies of them in order to modify them entering my data (included some specific water consumption data). I didn't remove any of the existing ...

Re: negative values among the inventory inputs

Hi, in order to solve the problem I mentioned in the previous post, I dowloaded and checked the matrices (both). In the matrices the values are all negative because they are all input flows. So I think that it isn't a data related issue, nor a modelling related one....but the problem is that I am pr...

negative values among the inventory inputs

Hi everybody, I'm running an LCA study and I think I'm having problems with the inventory. The LCA in question is about onions production and the aim is to asses blue water footprint. The system is very simple (it's just a sort of "training "case study) and I'm using Ecoinvent 2.1. I have installed ...

Re: differente results in the alu can vs pet bottle" case st

Hi,
just to have a further confirmation referring to my previous post: I obtained different results also in the comparison of ALU can recycling scenarios (see the picture below). Is this related to the same bug you mentioned?

Re: differente results in the alu can vs pet bottle" case st

Thanks Sebastian. I have to specify that I posted a graph that I had by trying some modifications in the tutorial exercise. By using the exact figures of the tutorial the graph was a little different from the one I posted but also still very different from the tutorial results...so I didn't re-post ...
