Biowaste to biogas

Hello, 

I have a hard time to wrap my head around the "treatment of biowaste for anaerobic digestion"-dataset. I'm looking for some kind of climate impact for the production of biogas from biowaste. Is this possible to find from this dataset? If I look at the dataset (allocation, cut of by classification):

"treatment of biowaste by anaerobic digestion"

Reference product: Biogas

Location: CH

LCIA -> IPCC2013

I don't see any climate impact. Is it possible to find this information from any other dataset?

Best regards, Jacob

Dear Jacob, 

 

See the description of "Handling of Waste Products" in the description of the Cut-off system model. In particular: "Any non-waste by-products of a waste treatment (i.e. not other waste products) are cut off and do not give a credit to the producing activity. The point of cut-off is therefore the end of the waste treatment. This also means that the resulting products are available in the database and can be used as burden-free inputs in other activities." This modelling is specific to the Cut-off system model.
