In addition to these, the waste
products generated from the plant mediated synthesis processes
are usually compatible with the environment since these particles
are resulted from natural plant extracts. On the contrary, the
waste products of microbial synthesis methods are likely to be
dangerous to the environment depending on the type of microbe
used for the synthesis. As far as the safety of biological synthesis
procedures is concerned, the plant mediated approach has less or
almost zero contamination and thus it has much reduced impact
on the environment
