Extended tools able to create Ecospold2 files:
Climate-specific and material-specific tool for open dumps, unsanitary landfills and sanitary landfills ('Landfill 2017.xlsm')
Material-specific tool for open burning ('Open Burning 2017.xlsm')
Material-specific tool for municipal incineration ('Municipal Incineration 2017.xlsm')

Central information repository ('Central Repository 2017.xlsm')

Correction of landfill gas generation: In extreme climates it is likely that landfill gas generation is affected by lack of temperature or humidity. This was not properly reflected in the previous tool. In the corrected tool low temperature and low precipitation rates will reduce the landfill gas generated from a waste.

The inventory of air emissions from the open burning tool failed to include emissions of non-fossil Carbon monoxide. In the corrected tool it is included in the inventory.  

Correction in the Central Repository, sheet 'DS info' where new dataset names are created. Use of the name suffix (column K) had lead to an unnecessary space before a colon. This was corrected.

Corrected tools:
tool for open dumps, unsanitary landfills and sanitary landfills ('Landfill 2017.xls')
Material-specific tool for open burning ('Open Burning 2017.xls')
Central information repository ('Central Repository 2017.xls')

Correction of calculation of long-term transfer coefficients in tailings impoundments (ore refining waste): In the modelled long-term, the washout of carbonate buffer will cause the pH in the impoundment body to drop and change leachate concentrations (cf. Doka 2003 (ecoinvent report 13-III) on page 26f). The factor expressing these changes (xe) was not properly included in the Excel formulas calculating the long-term transfer coefficients. In the corrected tool the formulas for long-term coefficients were corrected. The similar tool for landfills ('Landfill 2017.xlsm') did not have this error and used xe properly.
Corrected tool:
tool for tailings impoundment (ore refining waste) ('Tailings Impoundment 2017.xlsm') 

17 Dec 2018
Veff formula in landfills and tailings was corrected, was faulty (numerically 0.1% difference)**

15 Sept 2019:
Open Burning Tool: had an error in calculation of uncertainty of the share of thermal-NOx (Sheet 2OpenBurn", cell F103) when the thermal-NOx-share was set to zero (Which is an extreme user choice).
Also the technology comment for thermal NOx amount (cell E184) was reading FALSE, when thermal-NOx-share is 0%. Corrected to "" (no text).

12 March 2020:
• Included the new exchanges for "waste mass placed in landfill" and "organic carbon placed in landfill" in the ES1 and ES2 inventories.
• Included a table that shows the synopsis of the figures for those exchanges (mean amounts and GSD). in sheet "prop".
• corrected usage text for "coatings in CRT screens" (3 instances ecoinvent 2013, ecoinvent CH 2015, ecoinvent GLO 2015)
• Included soft capping of infiltration rate to stay below 2000mm/year also in landfill model (not only tailings) and introduced a switch to consistently add/1)/remove(0) the soft capping in the Central Repository, sheet "General Data", cell F82

25 Apr 2020:
• In the compilation of the ES2 contents an error was detected for the tags for literature sources: The "place of publication" was not correctly referenced, but instead a repeat of the source UUID was shown. Affected were the landfilling workbooks (Landfill 2018.xls, Tailings Impoundment 2018.xls). This was corrected and the ES2 tag for sources now shows the correct place of publication, if one was given in the source's definition. 

• Also the literature source information in ecospold1 (Sheet "X-Source") was static. This has now adapted to reflect the chosen source defined in Central Repository's sheet "DS info".

14 Jun 2020:
•Landfill 2020.xls, sheet "air & energy", the calcualtion of fossil ST air emissions (D94:F96) had negative values for % biogenic carbon in degraded waste of 100% (%BioCdeg), due to a calcualtion error in Excel (i.e. 1-1 < 0 ). %BioCdeg was re-routed to be taken from sheet "control board" and there sanitized to be within the bracket [0-1]. The complement for fossil C ( 1 - %BioCdeg) was similarly sanitized to be within the bracket [0-1], sheet "air & energy" D94:F96 and "leachate treat" A380:B392.
• Landfill 2020.xls: included waste heat emissions also in ES2 invnetory (as other tools have)
• Landfill 2020.xls: in the ES1 inventory the processes "extrusion, plastic pipes" and "reinforcing steel, at plant" were not found as they had a CH location, changed to RER location.
• Open Burning: added waste heat emission (upper heating value) to inventories
• CentralRepository: EA has changed Excahnge names to waste polyethylene terephthalate (from waste polyethylene terephtalate, i.e. wo. th). Changed to new name in sheets "waste input" (ES2) and "DS info".
• CentralRepository: In sheet "waste input", Column GK replaced formula for checking on new IMExch entries and missing new UUID.
• The factor expressing concentration changes in leachate after the carbonate drop (xe) was wrong for the oxianion arsenic. Correct is 0.01. Affected were the landfilling workbooks (Landfill 2018.xls, Tailings Impoundment 2018.xls). Affected to varying degrees are landfilled wastes with arsenic in them and a landfill carbonate phase shorter than 60'000 years.
• Tailings 1018.xls: Leaching dynamics for Manganese was wrongly exponential, instead of linear. Corrected. Effect on datasets is limited, as often LTTK was already 100%.
