• Goal and scope definition Our study seeks to assess the environmental burdens, related to two different retting processes both applied in relation to the production of hemp fibres for composite applications: traditional field retting and enzymatic retting. The retting process (Meijer et al., 1995) demonstrates the role of fermentation in the food industry, albeit that the fermentation is uncontrolled compared with many food industry applications. • Peeling test enables to define optimal retting degree to ease fibre extraction. Breaking means removing the dry wood portion which has been decomposed by the retting.
