TL;DR: In this paper, the authors discuss the use of various feedstocks in the production of biosurfactants, which not only reduces the cost of waste treatment but also provides an opportunity to profit from the sale of the bio-factant.
Abstract: The quest for a chemical surfactant substitute has been fuelled by increased environmental awareness. The benefits that biosurfactants present like biodegradability, and biocompatibility over their chemical and synthetic counterparts has contributed immensely to their popularity and use in various industries such as petrochemicals, mining, metallurgy, agrochemicals, fertilizers, beverages, cosmetics, etc. With the growing demand for biosurfactants, researchers are looking for low-cost waste materials to use them as substrates, which will lower the manufacturing costs while providing waste management services as an add-on benefit. The use of low-cost substrates will significantly reduce the cost of producing biosurfactants. This paper discusses the use of various feedstocks in the production of biosurfactants, which not only reduces the cost of waste treatment but also provides an opportunity to profit from the sale of the biosurfactant. Furthermore, it includes state-of-the-art information about employing municipal solid waste as a sustainable feedstock for biosurfactant production, which has not been simultaneously covered in many published literatures on biosurfactant production from different feedstocks. It also addresses the myriad of other issues associated with the processing of biosurfactants, as well as the methods used to address these issues and perspectives, which will move society towards cleaner production.

TL;DR: In this paper, a comprehensive review of municipal solid waste generation and its characteristics is presented, providing a bird's-eye view of the suitability of various technologies for energy production, providing up-to-date information about it.
Abstract: Solid waste treatment and disposal is a global challenge for the development of a sustainable society. The problem has been exacerbated by a rise in waste products as a result of population growth and urbanization. Ever-increasing municipal solid waste, together with its high proportion of organic waste and its unscientific disposal, contributes to Greenhouse gas emissions and other air pollutants. Municipal solid waste (MSW) mismanagement not only has harmful environmental consequences but also poses public health risks and raises other socioeconomic concerns. The mitigation approach requires an environmentally sustainable interpretation of the waste for its management and treatment. The waste-to-energy conversion provides a solution to environmental issues such as Greenhouse gas emission and waste management, thereby helping to achieve a green environment with a simultaneously prospering economy. This paper provides a comprehensive review of municipal solid waste generation and its characteristics. It provides a bird's-eye view of the suitability of various technologies for energy production, providing up-to-date information about it. It also covers challenges and perspectives in this field of research.
