A profitable future for Australian agriculture; biorefineries for higher-value animal feeds, chemicals and fuels : final report 2015/902
(Sugar Research Australia Limited, 2019) O'Hara, I; Harrison, M; Speight, R; Doherty, W; Vancov, T; Zhang, Z; Cox, S; Hobson, P
The Biorefineries for Profit project began in 2016 with a goal of establishing profitable bioproduct technologies for the Australian sugar, cotton, forestry, and pork industries. The project has developed technologies to turn agricultural waste into high-value products including animal feeds, chemicals, and advanced fuels. The project has also built the value-chain knowledge and human/organisational capacity needed to capture future biorefinery opportunities for Australian agriculture.
Flocculation and sedimentation of slow settling mud and mud cake conditioning : final report 2012/056
(Sugar Research Australia Limited, 2015) Doherty, W; Rainey, T; Bakir, H
The project aimed to improve the flocculation and sedimentation of slow settling mud, and reduce the pol/moisture content of mill mud by: Identifying key parameters which are associated with difficult to clarify soils; Identifying processes to improve the clarification of poor quality cane; and Identifying a strategy to condition filter cake that is difficult to process. The project seeks to realize its objective by conducting physico-chemical assessment of different soils from cane fields reported to produce juices that are difficult to clarify. Results from the assessment will be used to identify an additive/process that can be used to bring about particle aggregation and improved settling of the floc particles. Permeability and compressibility parameters of mud cake obtained from the difficult to clarify soils will be conducted using a custom-built laboratory mud cake former.
Increasing sugar recovery through improved mill sanitation and biocide application : final report 2020/203
(Sugar Research Australia Limited, 2021) Fernando, A; Shi, C
Undetermined sucrose loss during the processing of sugarcane to sugar is estimated between 1-2%, being a large financial loss to the industry. Microbial infection of sugarcane juice is from the microorganisms that enter the mill with the cane supply, and those from the floor washing and filtrate. Microbial degradation contributes 93% of the sucrose loss in mixed juice. Effective cleaning and sanitation procedures are needed to reduce microbial degradation in a factory. However, the hygiene practices vary among Australian mills. Biocides are not routinely used in Australian mills, though they are used overseas.
