Expanded EVA is an extremely versatile and lightweight material, but difficult to recycle since, once cross-linked, it is only able to partially bond to the virgin raw material if reintroduced into a new production process.
EVA-R was born from the collaboration with Viriam : a latest generation EVA compound obtained from the reprocessing of pre-production EVA waste that has already been cross-linked.
This compound allows us to drastically reduce waste, avoiding tons of material going to landfill every year, promoting the circularity of our products and processes.
This sole is produced with 20% regenerated EVA material.
From this percentage of use we begin to notice a decrease in the fluidity of the material in the screw, with a consequent increase in the risk of bubbles or lumps during the molding phase.
However , the particular design of the mold and the excellent characteristics of the Viriam EVA-R material allow rare and occasional aesthetic imperfections to be camouflaged , making the sole indistinguishable from another made with 100% virgin EVA.
Laboratory tests demonstrate that the soles produced with up to 20% recycled EVA maintain the technical-physical characteristics of virgin materials unchanged, namely flexibility, lightness, comfort and abrasion resistance.
Only the aesthetic part can reveal the nature – imperfect but unique – of a compromise to be accepted if one consistently believes in sustainability.
