Welcome to the BioCompass Online Decision Tree.

An environmental assessment tool

This guide has been developed to enable companies throughout the composites sector to make well-informed decisions about the likely environmental benefits of using crop-based materials without the cost and time requirements of conducting detailed life-cycle impact studies.

The tool has been designed to give an indication of how the environmental impact of a composite part changes as a function of the types and quantities of the fibres and matrices used in a composite structure, as well as the manufacturing route chosen.
