Foreword This report provides an assessment of the mallee woody crop supply chain, based on a comparative assessment with the sugar supply chain. The report will assist in developing a sustainable supply chain for the mallee industry and its stakeholders, including farmers, harvesting contractors, biomass processors, biomass markets as well as university, private and public sector industry representatives. While the report is of particular relevance to the mallee industry of Western Australia, where mallee trees are an integral part of wheat cropping systems, the findings are also relevant to other mallee areas in NSW, Victoria and Queensland. The report contrasts the mallee and sugar supply chain and recommends improvements to the mallee woody crop supply chain, covering, • Crop production. • Harvest and transport systems. • Products and processing requirements. • Industry and business structures. • Supply chain planning and management, and • Supply chain modelling and economic considerations. The project was funded from RIRDC Core Funds which are provided by the Australian Government. In-kind commitments were provided through the Future Farming Industries CRC and the University of Southern Queensland. This report is an addition to RIRDC’s diverse range of over 2000 research publications and it forms part of our Bioenergy, Bioproducts and Energy R&D program, which aims to meet Australia’s research and development needs for the development of sustainable and profitable bioenergy and bioproducts industries.
