sugarcane, in sugar refinery

Contents

Inventory refers to the production of 1 kg sugar, respectively 1 kg of ethanol (95% w/w dry basis, i.e. 1.05 kg hydrated ethanol 95% wet basis), 1 kg of excess bagasse (wet basis, 79% dry matter), 1 kWh of electricity and 1 kg of vinasse. The multioutput-process 'sugarcane, in sugar refinery' delivers the co-products 'sugar, from sugarcane, at sugar refinery' and 'ethanol, 95% in H2O, from sugarcane molasses, at sugar refinery', 'bagasse, from sugarcane, at sugar refinery', 'electricity, bagasse, sugarcane, at sugar refinery' and 'vinasse, from sugarcane molasses, at sugar refinery'. Economic allocation with allocation factor for common sugar production stages of 80-85% to sugar, 10-11% to ethanol. Allocation according to carbon balance for CO2.

includedProcesses This dataset includes the transport of sugarcane to the sugar refinery and the processing of sugarcane to sugar, ethanol (95% w/w), bagasse (79% dry matter, excess), excess electricity and vinasse from ethanol production. System boundary is at the sugar refinery. Treatment of waste effluents is not included (most wastewater is spread over the fields nearby). Packaging is not included.

technology

Juice extraction is performed through milling (not diffusion). The juice is then purified and crystallized to sugar according to standard processes. Ethanol is produced by standard fermentation and distillation techniques. Energy supply is done by combustion of the bagasse resulting from the extraction stage. The two main products are sugar and ethanol.
