Introduction
============

T-reX [T(ool) reX (reduce, recycle, etc.)] is a python package that makes it easy to calculate the waste generation and material demand footprints of any product or service inside of future and prospective life cycle assessment (LCA) databases. Currently tested with the database ecoinvent 3.5--3.10.

For more information on the background and motivation of T-reX, see the manuscript on its  `Github repo <https://github.com/Stew-McD/T-reX_Publication>`_.
