\u201cHistorically the international pellet market has focused on forest biomass,\u2019 Dr Moreira<\/strong> said.<\/p>\n\n\n\n

\u201cBut with regulations in Australia ruling wood pellets not classified as renewable, we are trying to find alternative sources of biomass to produce pellets of the same quality.<\/p>\n\n\n\n

\u201cWood has a lot of lignan, one of the most important components, and these weeds have a lignan content of about 25 per cent, which is competitive.<\/p>\n\n\n\n

\u201cThe other key finding is we can make market grade pellets, which means there are some weed to pellet conversion pathways that can provide market grade biofuels we could sell.\u201d<\/p>\n<\/blockquote>\n\n\n\n

The pellets were produced by Ipswich startup, WorkEco, thanks to a seed grant from the Australian Government\u2019s Strategic University Reform Fund (SURF). <\/p>\n\n\n\n

Study co-author and AgriSustain lab leader Associate Professor Sudhir Yadav<\/a> said the work aimed to reduce the environmental footprint and improve the sustainability of the agricultural sector.<\/p>\n\n\n

\u201cAgencies like the Australian Renewable Energy Agency have predicted bioenergy will supply 20 per cent of energy demand by 2050,\u201d Dr Yadav<\/strong> said.<\/p>\n\n\n\n

\u201cIt\u2019s an optimistic but achievable target and a lot of research is required to bridge that gap.<\/p>\n\n\n\n

\u201cAnother of our research areas is converting low value biomass and agricultural residue \u2013 such as crop stalks, straw, wood chips, and animal manure \u2013 into functional products.<\/p>\n\n\n\n

\u201cThis work could provide a source of revenue for a startup, solve a problem for a local government and more importantly reduce the environmental burden.\u201d<\/p>\n\n\n\n

Dr Yadav said the work was far from complete.<\/p>\n\n\n\n

\u201cWe have many more weed species to test but we know from a sustainability perspective environmental weeds have a limit and eventually supply will become a problem,\u201d Dr Yadav said.<\/p>\n\n\n\n

\u201cWe\u2019re also thinking about other potential sources of biomass, like green waste collected by councils and households and even some broadacre crops like sorghum.\u201d <\/p>\n<\/blockquote>\n\n\n\n
