Biosurfactants: Opportunities for the development of a sustainable future

Changes in the environment in recent years have led to the examination of the role and influence human activities on it. Attempts to quantify the impact of these activities by developing standardized modeling frameworks through life cycle sustainability assessment is one such approach in the context of sustainability seeking to measure the impact of human interventions from a holistic perspective that includes economic, social, and environmental dimensions. Sustainable alternatives to synthetic products are always keenly sought after. Biosurfactants are emerging as suitable alternatives to the predominant less sustainable petroleum-derived counterparts. Several factors surrounding their production, distribution, and end-use, however, still needs to be considered before conclusively confirming their sustainability. Though data are still limited in that subject matter, research showing their impact on some sustainability indicators is highlighted. This review discusses the potential of biosurfactants as sustainable products in the context of social, economic, and environmental aspects.
