Clearly control over the biodegradability is also possible, which offers the unique potential for the use of shaped cellulosic objects to replace traditional petrochemical melt-processed plastic objects. In this manner, the degradability of cellulosic materials in the environment may be tuned -with materials designed such to fully degrade after the expected lifetime in application. Thus, there is clear scope for application of this method in a single-use or repeated use fashion, dependent on how legislation changes. This of course takes further work to prove.
