T-reX.main

Main module of the T-reX tool.

This script serves as the entry point for the T-reX tool. It orchestrates the overall process, including the setup and execution of various subprocesses like database explosion, material and waste searches, and the editing of exchanges.

The script supports both single and multiple project/database modes, as well as the option to use multiprocessing. It also facilitates the use of the premise module to generate future scenario databases.

Customisation:

• Project and database names, and other settings can be edited in config/user_settings.py.

• Waste search query terms can be customised in config/queries_waste.py.

• The list of materials can be modified in config/queries_materials.py.
