Ecosynthetix has developed and commercialized a starch based biolatex that can be used in adhesives, paper and cardboard binder, carpeting, and a number of other applications[fn]http://ecosynthetix.com/_docs/whitepapers/ECO-Rheological_properties_of_.... The patented process uses proprietary starch nanoparticles to form a colloidal latex. This creates low viscosity polymers with high molecular weight, allowing for the creation of high density binders required by the packaging industry. EcoSphere Biolatex binder is more stable than petrochemical binders like styrene butadiene latex, and perform just as well if not better[fn]http://www.ecosynthetix.com/ecosphere_facts.html[/fn]. These binders are used in things like packaging material to make vibrant inks adhere to high gloss surfaces. McDonlads currently uses EcoSphere Biolatex binders in their burger and sandwich boxes.
These crosslinked starch nanoparticle binders have been shown to improve the paper coating production capability with better outcomes than both conventional starch based latex binders and petroleum latex binders. Essentially, these binders performed better in various industrial equipment used to manufacture high density paperboard products.
This nanotechnology innovation is used as a replacement for petroleum based emulsion polymers for packaging and ink binders, paints, coatings, carpets and adhesives.
EcoSphere Biolatex can be shipped and stored as a dry granular matrix; greatly reducing weight of the finished binder. This reduction in weight significantly reduces the energy consumption during transport. Additionally, EcoSphere Biolatex outperforms synthetic petroleum latex in strength, aesthetics, and color reproduction while reducing carbon emissions in the production process by 3.3 pounds of carbon dioxide per pound of biolatex substituted for petroleum based latex. The properties of the latex also enhance the recyclability of finished goods and require less binder to produce equivalent results to petroleum based latex.
Uncertain due to proprietary nature of the technology. This technology is likely to be as safe as or safer than conventional petrochemical binders.
