CARBONCLOUD'S SUPPLY CHAIN MODEL
Calculating GHG emissions from refinement
CarbonCloud enables users to allocate the emissions from production between the main product and by-products in the food manufacturing process by specifying 3 factors:
- The amount and type of input in kg per kg of output from a refinement step and the energy used during that step determine the total emissions up until this stage.
- Whether the removed parts serve as by-products
E.g., Using 3 kg of potatoes for 1 kg of potato chips, where 0.9 kg is peeled potato skin and the remaining difference is evaporated water.
- If there is a by-product, emissions are allocated according to the economic value the specified by-products have per kg (e.g., 0.2 € per kg of potato peels sold for livestock feed) and the economic value of the main product (e.g., 12 € per kg of potato chips).
The economic value of by-products relative to the economic value of the main product determines how emissions will be allocated between the corresponding by-product and the main product If there are no by-products or if the by-products have no economic value, the emissions up until that step are allocated to the main product.
For automatically modeled products and intermediary ingredients from the CarbonCloud library, CarbonCloud measures 13.3% spoilage in total for all supply chain steps modeled, per the data from the United Nations.
