The investigations of transformations of specific feedstocks into specific potential platform molecules can be exemplified by the extension of the work on 5-hydroxymethylfurfural (HMF), a molecule derivable from dehydration of fructose, to proposals of new functional platform molecules derived from HMF, such as its cyclopentanone derivatives. The second approach is to follow a more product orientated approach. For instance, Couto gave an overview on the production of industrially relevant metabolites from biological waste, Ravindran et al. outlined the utilisation of vegetable pomace to secondary use, and Van Dyk et al. described compositions of food wastes, valuable compounds and potential products. Both approaches are reasonable with regard to the specific feedstock, but neither consider whole supply chains, nor define precise criteria for these integration points. Without the consideration of the whole supply chain we are unlikely to answer which transformations and reaction pathways have a chance of being practically implemented.
