Numerous studies in academic literature study bioeconomy as part of the worldwide desire to find new or more sustainable ways to obtain economic and cultural growth. They view it as a new economic sector used to invent, promote and develop processes compatible with a durable environment. Bioeconomics has had a constant development in scientific literature in the last two centuries. It was created to link to powerful sciences: biology and economics, in an endeavor to broaden the existing theories in both disciplines or create new ones. The connection was created two-fold: using economic concepts and models to analyze biological phenomena or using a biological perspective to study economic behavior. This paper endeavors to present a brief overview of the different approaches found in literature concerning the concepts of “bioeconomy” and "bioeconomics", their similarities, differences and areas or overlap.
