Re: ELCD 3.2 Hard coal and natural gas consumption saves lan

Hi Andreas, Thanks! I looked again in the ReCiPe characterisation factors and the flow "transformation, to unknown" has a negative CF of -0.4. It is described here: http://www.lcia-recipe.net/file-cabinet in the main report from 2013. The reason stated is that 61% of all land is non-natural and 39% ...

ELCD 3.2 Hard coal and natural gas consumption saves land

Hello everybody, I just wanted to inform you about a bug I found: I am using the latest openLCA version with the elcd 3.2. databank and impact assessment methods. For some reason, when using ReCiPe (H) the flow "transformation, to unknown" contained in the inventory of "Natural Gas Mix, consumption ...

Electricity consumption saves water at midpoint

Hello fellow openLCA people! I have a question concerning the effect electricity consumption has on water depletion in the LCIA because I find it quite weird: I am using openLCA 1.5.0 and the elcd databse 3.0. In my model the use of any electricity flow from the elcd database is saving water at the ...

System expansion: "avoided product" not calculated

Hello openLCA users! I have a problem with making openLCA calculate the production of avoided products in the inventory. I am modelling the life cycle of a machine from cradle-to-grave. During the EOL/Disposal phase some of the plastic and aluminium used for the machine's components can be recycled,...

Flow needed in elcd: "unspecific manufacturing component"

Hello openLCAcies, I am building a model for a rather complex machine with a cradle-to-grave inventory. For the construction phase I need data for many different and sepcific components like pumps, sensors etc. I am pretty sure that I will not get all the data I need (in time) and that I will have t...

Input from Manufacturing Phase to Operational Phase

Hi openLCa community! I am currently working on an LCI for a membrane bioreactor (MBR)-based waste water treatment technology. I want to include the manufacturing of the single components of the MBR as well as the operational phase and the disposal of the single components. I am wondering now how to...
