CRAFT - Chemical Reactivity and Fate Tool


CRAFT is a software suite that has been designed to assist scientists in the area of product safety, hazard and risk assessment and toxicology to interactively evaluate the chemical reactivity, persistence, biodegradation and fate of chemical compounds in the environment. CRAFT provides decision support to faster estimate the environmental impact of existing chemicals or to discover and optimize better and safer new chemical entities and products.

Features & Functionality

  • Generation and evaluation of biodegradation products of chemical substances in the environment
  • Generation of degradation trees and pathways weighted by the likelihood of occurrence of the individual reaction steps
  • Built-in knowledge base of chemical reactivity and biodegradation derived from the University of Minnesota Biocatalysis and Biodegradation Database (nowadays maintained as Biocatalysis/Biodegradation Database by EAWAG)
  • Extendible knowledge base to include user-defined models and rules for chemical reactivity and biodegradation
  • Flexible design to plug-in third party tools or to call external applications
  • Optional usage of on-line data sources to collect information about analyzed chemicals, e.g., PubChem
  • Generation of printable and editable reports with user-definable level of detail
  • Open-source application available under LGPL licensing terms

User Interface

In order to maintain, extend and apply the knowledge base for the evaluation of chemicals, CRAFT consists of two main applications.

  • CRAFT Editor - GUI-based program to inspect, modify and extend the contents of the knowledge base
  • CRAFT Explorer - GUI-based program providing a wizard-driven interface with a predefined workflow that supports the user during the evaluation session (including command line interface for batch mode execution)
