Overall consumption of PP in 2011/12216,347 tons 19Market for PLA in AustraliaHypothetical situation30% of the total PP production would be replaced by PLA from sugar cane bagasse

49%147,000 tonnesTherefore, 44 100 tonnes (30% of 147,000 tonnes) would be replaced by PLA

20The yield of PLA from solid bagasse is 80% (Groot & Born, 2010)55125 tonnes of bagasse would be necessary;

Approximately 34000 tonnes of bagasse is produced per hectare of sugarcane growth: 1.6 hectares of sugarcane farmland would be necessary for the required PLA production

22Case Study: Biodiesel from palm oil in Malaysia used as a 50% blend in diesel in Malaysia

BiodieselFossil Fuels cannot supply the demandIncreasing demand of energy23Case Study: Biodiesel from palm oil in Malaysia used as a 50% blend in diesel in Malaysia

BiodieselMalaysian case study: biodiesel from palm oilPalm: most productive crop for oil extractionThe country is one of the largest producers of palm oilBiodiesel can be blended with petroleum dieselMPOB: policies to enhance the production of biodiesel

24Case Study: Biodiesel from palm oil in Malaysia used as a 50% blend in diesel in Malaysia Functional Unit: 1 MJ of fuel used in engine vehiclesLimitations:Diesel: American InventoryBiodiesel: Blending process neglectedTransport to centres of consumption: neglectedProduction of Petroleum-Diesel
