BIO-BASED PRODUCTS FROM BRASSICA CARINATA A. BRAUN OIL AND DEFATTED MEAL BY A SECOND GENERATION BIOREFINERY APPROACH

摘要

The interest in a biorefinery approach as a sustainable production system alternative to some petroleumrefineries does not have to be limited to bioenergy chains or to the use of undifferentiated biomasses or waste. Insome particular industrial production systems, through a strong link to a high quality agricultural production chain,dedicated biomasses characterised by a high amount of specific compounds (oil, starch, protein, minor compounds asbioactive molecules) can be produced and used in non food fields either in their native form or after small chemicalmodifications. In this way, the plant cultivation phase represents the first step of the biorefinery chain and the startingpoint for further technological or biotechnological processes. In this paper, a ten-year Italian experience of plantbasedmaterial production, such as organic fertilisers, amendments or biostimulants with an allelopathic activity incontaining some plant pathogens and pests will be presented and discussed. Starting from Brassica carinata seedmain components (oil, defatted seed meals), and using patented industrial technologies, it was possible to produce aseries of different solid (meals, powder, granules, pellet) and liquid products (oil emulsions containing meals) that arenow widely applied both in organic and conventional horticulture. This operating method, whose benefits will beevaluated and reported by an environmental balance based on carbon footprint evaluation, enables a practicalalternative to conventional fertilisers and pesticides.
