a
The yield of the product was obtained from 1 tonne FW.
b
The unit price of the product was determined based on the scale, purity, application, and the manufacturers from different regions.
c
The revenue range = yield (minimum) × price (minimum) to yield (maximum) × price (maximum).
d
The yield of animal feed was also inquired from the website (https://www.cgiar.org/research/publication/global-experiences-on-waste-processing-with-black-soldier-fly-hermetia-illucens-from-technology-to-business/).
e
The price of furfural and 5-HMF were also inquired from the website (https://www.chemicalbook.com/ProductList_En.aspx?kwd=HMF).
