Known Data issues | ecoinvent 3.2

This page lists all known data errors in ecoinvent version 3.2. We are sorry for any inconvenience these cause and are working hard to eliminate these issues in an upcoming update to the database.

We document these issues openly to make our users aware of these problems and to help them understand the errors so they may work around them while we work on the update and error fix.

Current Known Issues | ecoinvent 3.2

  • In the consequential system model, the following 4 constrained markets receive no input from their marginal supplier: market for residual hardwood, wet; market for residual softwood, wet; market for residual wood, dry; market for venting of nitrogen, liquid; market for ground granulated blast furnace slag

 

  • In the consequential system model, the "market for hydrogen, liquid" RoW is not present, and consumer activities originally linking to this market receive a 0 amount of "hydrogen, liquid".

 

  • The following activities had the input of solvent/water removed, following the rule of chemicals in solution: alkyd paint production, white, solvent-based, product in 60% solution state; alkyd paint production, white, water-based, product in 60% solution state; alkyd resin production, long oil, product in 70% white spirit solution state; printing ink production, offset, product in 47.5% solution state; printing ink production, rotogravure, product in 55% toluene solution state.

 

  • Unfortunately, the demanding activities of the resulting products (listed below) also lack this input of solvent/water: alkyd paint, white, without solvent, in 60% solution state; alkyd paint, white, without water, in 60% solution state; alkyd resin, long oil, without solvent, in 70% white spirit solution state; printing ink, offset, without solvent, in 47.5% solution state; printing ink, rotogravure, without solvent, in 55% toluene solution state.

 

  •  The "market for copper" is distorted in v3.2. It is supplied by the activities "copper production, from imported concentrates" DE and GLO, which were converted from v2.2, and generated automatically respectively. Those activities were not intended to produce "copper" and are already being corrected and renamed in the working version of the Undefined database (accessible through the ecoEditor). The next release of the calculated database (v3.3, scheduled for 2016) will contain the corrected activities and the corrected market. The users which want to use the "market for copper" in v3.2 can correct it the following way: edit the market and remove "copper" exchanges coming from "copper production, from imported concentrates" (DE and GLO); increase the relative contribution of the other producers to cover 100% market share.

 

  • For the products where market groups exist, all RoW activities are getting their supply from GLO market groups. This can lead to big errors in some cases, specially when there are many local consumers. This has been corrected for the next version of the database v3.3.

 

  • The dataset "propane extraction, from liquefied petroleum gas" is modelled incorrectly, the input of "liquefied petroleum gas" in incorrect.
