Rapeseed - a valuable renewable bioresource

Abstract

The transition to a sustainable economy determines a shift of feedstock for the energy and chemical industries from fossil fuels and petrochemicals to renewable resources. The use of annual plants as a major source of renewable resources represents a valuable alternative both from an economical point of view and from an environmental one. Rapeseed is mainly used as a bioresource for extracting oil and protein for the food industry. Rapeseed stalks represent a valuable source of cellulosic fibres for the paper industry, but their technical use is not put into operation. This review deals with rapeseed as an alternative source of natural chemicals for industries and of cellulosic fibers for the paper industry. The botanical features, including chemical value of rapeseed, are briefly discussed. Also, the basic properties of fibers separated from rapeseed stalks are presented. The utilization potential of rapeseed plant parts is also underlined.
