An existing demonstrator for E-maintenance solutions for advanced aviation maintenance staff was extended to incorporate abilities as a collaborative environment for developers of sustain­able products. Most of the existing core concepts and functions in the demonstrator were found to be viable: work context management, modularisation, information and web services access. This paper pres­en­ts more in detail the modularization concept used in the demonstrator and its potential use in collaborative environments for sustainable prod­ucts developers. This concept if implemented allow faster integration of external web services and information sources into the sustainable product design work­flows and processes.
