EoLPAFT This code was written for the tool shared in the peer-reviewed manuscript "An End-ofLife Plastic and Additive Flow Tracker Tool for Scenario Forecasting."

Also, the supplementary file "Chea et al - EoLPAFT-Supplementary-Final.docx" describes the tool Requirements, the EoLPAFT.py Script, User Specifications and Calculations, Material Flow Results, The model_dev.py Script, The pipe_test_GUI.py Script, and The “MySQL Database” Folder

Requirements This code was written using Python 3.x. The following Python libraries are required for running the code: tkinter (https://docs.python.org/3/library/tkinter.html numpy (https://pypi.org/project/numpy/) PIL (https://pypi.org/project/pillow/) plotly (https://pypi.org/project/plotly/) pandas (https://pypi.org/project/pandas/) datetime (https://pypi.org/project/DateTime/) io (https://docs.python.org/3/library/io.html) html2image (https://pypi.org/project/html2image/) tktooltip (https://pypi.org/project/tkinter-tooltip/) matplotlib (https://pypi.org/project/matplotlib/) xlsxwriter (https://pypi.org/project/XlsxWriter/)

How to use The Python Script requires no additional documents. To run the Python script, you need to navigate to the directory containing main.py. Then, you execute the following command either on Windows CMD or Unix terminal:

python main.py The GUI will open and allow use of the tool. The data can then be input by the user.

Outputs After running the Python script you will obtain the following files:

File name Description temp-plot.html Sankey Diagram Showing Normalized Flows Sankey_Diagram.png PNG version of Sankey Diagram above Optional documents that can also be generated:

File name Description Stream Summary Calculations.xlsx Shows MSW stream flows for scenario, current data marked by sheet date/time
