The Dendrino project concerns the development of renewable resources (in particular glycerol, a co-product of the biofuel industry) through the preparation of grafted and/or ionic dendrimers. These “cage” compounds can be used to clean up waste water or to desalinate salt water. The biosourced character aims to improve the eco- and biocompatibility of dendrimers and grafting on a resin-type solid will facilitate filtration and regeneration of dendrimer/resin complexes to consider recycling.
