Hi! This is Ander Martin from Spain. At the present time, I’m doing my secondment at Universitá Degli Studi di Genova, I came from San Sebastian, more precisely I belong to Ma+D waste recovery engineering business company. My task at the company is focused on WP1 where my scope is to produce lactic acid from renewable resources. For this purpose, lignocellulosic biomass is collected and processed to convert biomass waste into profitable chemicals.

The activities in which I’m working at Genova involves the synthesis of different amide based nucleating agents (NA) that improves the crystallinity and crystallization kinetics of the bio renewable poly lactic acid (PLA) during its processing as part of the WP1, task 1.4 (Synthesis of novel soluble/self-assembly nucleating agents based on symmetric oxamide, α-ketoamides compounds).
