Abstract Excessive utilization of synthetic plastics has led to a major detrimental impact on the environment. Plastic pollution and accumulation in water bodies have threatened the survival of marine life. Plastic pollution can be prevented by using biopolymers that are eco-friendly and can be naturally produced by certain living organisms. The biopolymers have environmental advantages over synthetic plastics, such as biodegradability and biocompatibility. In comparison to plants and other micr...

Abstract Polyhydroxybutyrates(PHBs) are a class of biopolymers produced by different microbial species and are biodegradable and biocompatible in nature as opposed to petrochemically derived plastics. PHBs have advanced applications in medical sector, packaging industries, nanotechnology and agriculture, among others. PHB is produced using various feedstocks such as glycerol, dairy wastes, agro-industrial wastes, food industry waste and sugars. Current focus on PHB research has been primarily on...

Abstract To mitigate the rising level of CO2, biological method of CO2 sequestration is one of the effective methods. Chemolithotrophic microbes are able to fix atmospheric CO2 and precipitated polymorphic minerals like calcite, vaterite and aragonite. Based on this, bioactive glass was synthesized by sol–gel process using polymorphic calcium carbonate mineral precipitated by chemolithotrophic Serratia sp. ISTD04. Characterization of bioactive material and its bioactivity was evaluated by SEM, E...

Abstract Crude glycerol, one of the ever-growing by-product of biodiesel industry and is receiving the closest review in recent times because direct disposal of crude glycerol may emerge ecological issues. The renewability, bioavailability and typical structure of glycerol, therefore, discover conceivable application in serving the role of carbon and energy source for microbial biosynthesis of high value products. This conceivable arrangement could find exploitation of crude glycerol as a renewa...

Abstract This article focuses on the use of biomass to produce transportation fuels such as synthetic natural gas, bioethanol and electricity under a sustainable scenario in West Africa in 2050. The aim of this work was to evaluate the feasibility of producing such biofuels using agricultural residues as feedstock in the studied area. The potential of biomass from ten agricultural residues was estimated in R environment using FAO data. Options were analyzed in order to generate portfolios of tra...

Abstract Vine shoots are the viticulture residues generated in high quantities after the grapevine pruning. They are lignocellulosic material poorly exploited as feedstock. These wastes are often dumped in the agriculture fields or burnt. Due to their availability and relatively low price, vine shoots are considered as potential feedstock for biochemical conversion into value-added products. In this work, two biorefinery scenarios using vine shoots as feedstock to co-produce chemicals are assess...

Abstract The expansion of ethanol production using sugarcane as feedstock is of significant commercial interest in South Africa due to its primarily use as biofuel. In this chapter three integrated sugar mill–based biorefineries coproducing sugar, ethanol, chemicals, and electricity are proposed for assessment in the context of South Africa. The feedstock considered in the plants are sugarcane, green harvesting residues, bagasse, and molasses. These biorefineries were designed to be integrated i...

Abstract The increasing load on the ecosystem with activities, such as deforestation, exploited land use, industrialization, and excess waste generation, leads to a global climate shift, which is one of the leading environmental issues of the world today. The basic biomolecules for the production of biofuel include fatty acids, alcohols, and alkanes. Biodiesel is composed of monoalkyl esters of higher chain of fatty acids, produced though the transesterification reaction by alcohol in the presen...

Abstract Agroresidues are the waste by-products of agricultural crops and agroindustries. The generation of these waste materials poses disposal issues that lead to environmental and economic concerns. These issues could be addressed by utilizing these waste materials for the production of other value-added products. It serves as an abundant, inexpensive, and a renewable source for the production of various products. The agroresidual waste, such as lignocellulosic biomass, is mainly composed of ...

Abstract A large volume of solid and liquid waste is generated due to industrial and urban/suburban/agricultural activities. Management and handling of waste generated is nowadays burning issue for local authorities not only in urban areas, i.e., municipalities, but also in other regions in any country. With increasing urbanization and industrialization, generation of waste/wastewater appropriate disposal, treatment, and/or recycling are posing more challenges as the treatment and disposal costs...
