It seems they offer the calender service themselves now.

Setup

Make a new virtual environment and Install requirements, requires python 2.7

pip install virtualenv
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

deactivate # To deactivate environment after use

To run the server

export FLASK_APP=app.py
flask run

Import the Waste disposal calendar.ics into your calendar. I suggest creating new calendar anywhere because loaded file cannot be unloaded.
