Sugarcane Feedstock Emissions was created by clarice.vassallo
Hello,
I am using GHGenius version 5.02 to identify the life cycle emissions of sugarcane as feedstock.
Could you help me understand the following:
Kind regards,
I am using GHGenius version 5.02 to identify the life cycle emissions of sugarcane as feedstock.
Could you help me understand the following:
- Sugarcane as feedstock in the tool refers to sugarcane bagasse?
- What are the activities included under feedstock recovery? Does it only include the energy emissions associated with transforming sugarcane in sugarcane bagasse?
- Do the tool results include GHG emissions associated with machinery used in the field to plant and harvest sugarcane?
- Some countries use sugarcane burning as a practice before harvesting. Are there any sugarcane-burning emissions within the tool results?
Kind regards,

Sugarcane as a feedstock in the model is the sugarcane as it is delivered to a mill for processing into ethanol.
The bagasse the product after the sugarcane is extracted.
Feedstock recovery includes the energy used in the cultivation of the sugarcane. It does not include any processing of the sugarcane.
There are no emissions associated with the manufacturing of the machinery used in crop cultivation in the model.
The emissions associated with burning the sugarcane prior to harvesting can be included in the model by entering the faction of the area burned in cell J123 on the input sheet.

Hello,
Could you please clarify, after entering the fraction of the area burned in cell J123 on the input sheet, where can someone see the detailed emissions associated with burning the sugarcane before harvesting?

The emissions from burning the sugarcane are part of the Land Management emissions on the Upstream HHV sheet in cell X 15.
The emission factors are found on the Equip Emiss sheet column DX.

Thank you.
How are these emissions incorporated in the feedstock emissions results in the feedstock emissions tab?
When running the tool with and without the fraction of area burned (Input J123), only P10 from the feedstock emissions tab changes, which I assume only includes sugarcane burning for producing ethanol used in equipment during sugarcane land management.
The cell P18 in feedstock emissions provides the gCO2e/tonne of feedstock, which is, in this case, sugarcane (I will call it sugarcane A). During the production of sugarcane A, sugarcane A would be burned before being harvested. As ethanol is used during the harvesting of sugarcane A, there is also the upstream burning of sugarcane (sugarcane B ) from the ethanol.
Could you clarify if the Feedstock Emissions tab includes the burning of sugarcane A and B mentioned above?
Can you help me understand how burning sugarcane A is included?

The sugarcane burning emissions are not included on the feedstock sheet. We will correct that on the next update of the model.
Cell P12 on the Feedstock emission sheet should be
=Fertilizer!M219+'Equip Emis Factors'!DX27*(Fertilizer!M155)*(1-Fertilizer!M185)*Fertilizer!M159*1000
GHGenius has many circular references and iterates to resolve these. So will see that when burning is included in the emissions the feedstock recovery emissions also increase. This is because some ethanol is used in the harvesting process and the ethanol emissions increase because of the cane burning emissions.
I hope this helps.
