The "biobased world" is developing rapidly.  New and even greener materials are being developed at high speed and become available in larger volumes.

For Ground Consolidator applications this gives further opportunities. Today we had materials in our hands which were a clever mix of PLA and poly starch, manufactured bij Rodenburg. Bij playing with the ratios the biodegradation times can be tuned. Still, a lot is unknown about typical biodegradation (composting) times for pla based biopolymers at room temperature in a wet natural environment. Our tests at several locations last now for 3 and 4 years. It is becoming clear that the addition of natural fibers has a noticible effect. Pure PLA is degrading very, very slowly.

Still, even this semi-infinite degradation is interesting for GC applications. For the technical c2c constructions (with a design for recycling) for example the use of these materials may remove the last remaining fear of GC constructions in seawater that contribute to the plastic soup trouble. This is of interest for semi-permanent constructions like pipeline protection against freespans, or scour protection at offshore windmill posts. For further material-background please read the Polymers section in this website, also accessible from the Home Page

 

Natural fibers give signifant strengthening of composites. At the same time their application leads to initial reduction of stiffness in the composites. We will continue to use natural fibers, but we will also start using mineral fibers.

 

Taking these two aspects (pla, fibers) in account Anome Projects decided to further study PLA based polymers with basalt fibers and probably lime or barite (to tune the weight). Currently several mixtures are compounded in a collaboration with Pezy Product Innovation and CMB compounding.
