The paper summarizes the present and future course of biosorption and bioaccumulation, as the branch of
science, pointing out on their basic assumptions, philosophy and the goals. The processes are presented as new
tools for separation technologies of XXI century. The paper is the discussion with the literature on the future
prospects of those processes, pointing out that research should be oriented on the practical applications, in order
to make technologies from the processes and also discusses other than environmental possible future
applications. It presents an own point of viewon these techniques, after some years of working in this very area.
Biosorption and bioaccumulation, involve interactions and concentration of toxic metals or organic pollutants
(e.g. dyes) in the biomass, either living (bioaccumulation) or non-living (biosorption). The processes play an
important role in natural cycling of matter in the environment. The paper discusses the possibilities which offer
research on pollutants-biomass interactions, pointing out that the key to elaborate an efficient method working
for the nature would be to understand the mechanisms governing the processes, parameters which influence
both equilibrium and kinetics, through the observation of naturally occurring phenomena. Only then we would
be able to control and carry out under industrial regime, so the processes would work beneficially for the
environment.
