Biocomposites offer a significant non-food market for crop-derived fibres and resins. Considerable growth has been seen in the use of biocomposites in the automotive and decking markets over the past decade or so, but application in other sectors has hitherto been limited. Nevertheless, with suitable development, the potential exists for biocomposites to enter new markets and thus stimulate an increase in demand for non-food crops. This paper reviews some of the technological challenges being faced in bringing these materials to a wider market together with potential solutions, as well as discussing market forces influencing their commercial uptake.
