Roshan Paul of Leitat Technological Center, Terrassa (Spain) was blending 5% cellulose powders into PLA during extrusion but provided no data on the performance of the resulting biodegradable plastic. He had also prepared masterbatches of thermochromic dyes with PLA to make fibres for fire-protection clothing but admitted that the clothing gave no indication of skin temperature.
