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:

      1. 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.
      2. 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.
      3. 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.
