Glycerol Plasticizer In Bioplastic Price

using glycerol produced from biodiesel as a plasticiser

Using glycerol produced from biodiesel as a plasticiser

The price of glycerol is related to its degree of refinement, ranging from US$167/ton for crude glycerol to US$267/ton for technical grade glycerine and US$1000/ton for bi-distilled glycerol. The industrial use of glycerol is essential for the economic sustainability of the biodiesel industry in Brazil.

PAPER OPEN ACCESS Mechanical Properties of Bioplastics

In bioplastics production, plasticizers need to be added so that the plastics produced is more elastic, flexible and resistant to water [9]. Glycerol and sorbitol are widely used as plasticizers because of their stability and non-toxic. Glycerol and sorbitol are plasticizers to reduce fragility, increase film

Generally, as a plasticizers glycerine is used. However, also some of polyols, (sorbitol, xylitol) may be used as plasticizers ( Talja et al., 2007) . Furthermore, water sorbed in film acts also as plasticizer. The purpose of this work was to found novel application of glycerol , as plasticizers for starch derivatives films.
