“…Microalgae introduced into new environments also have the potential to become invasive species. There are an estimated 1-10 million algal species on earth, with the majority being microalgae (ElFar et al, 2022). Microalgae that are native or introduced to an area and become invasive are often referred to as harmful algal blooms (HABs).…”

There exists a global challenge of feeding the growing human population of the world and supplying its energy needs without exhausting global resources. This challenge includes the competition for biomass between food and fuel production. The aim of this paper is to review to what extent the biomass of plants growing under hostile conditions and on marginal lands could ease that competition. Biomass from salt-tolerant algae and halophytes has shown potential for bioenergy production on salt-affected soils. Halophytes and algae could provide a bio-based source for lignoceelusic biomass and fatty acids or an alternative for edible biomass currently produced using fresh water and agricultural lands. The present paper provides an overview of the opportunities and challenges in the development of alternative fuels from halophytes and algae. Halophytes grown on marginal and degraded lands using saline water offer an additional material for commercial-scale biofuel production, especially bioethanol. At the same time, suitable strains of microalgae cultured under saline conditions can be a particularly good source of biodiesel, although the efficiency of their mass-scale biomass production is still a concern in relation to environmental protection. This review summaries the pitfalls and precautions for producing biomass in a way that limits environmental hazards and harms for coastal ecosystems. Some new algal and halophytic species with great potential as sources of bioenergy are highlighted.

The development of biorefineries is a crucial step in the circular economy framework. In biorefineries, research is intensified towards utilizing feedstocks, which do not need arable land or compete with food sources. In this scenario, emerged, submerged and free-floating aquatic plants are garnering significant attention as potential feedstocks owing to their generation in huge quantities, especially in eutrophic water bodies, similar composition to lignocellulosic biomass with lower lignin content and requirement for only mild pre-treatments. Therefore, exploring the feasibility of using these aquatic plants for the production of various biocommodities in a biorefinery approach can be of prime importance. In light of this, the current review illustrates the use of some of the major aquatic plants for the production of different biocommodities. The main focus of the study is to shed light on the various biorefinery schemes that could be implemented using these aquatic plants. It also outlines the challenges and prospects of aquatic plant-based biorefineries. The findings suggest that various biorefinery schemes can be implemented using these aquatic plants and a combination of chemical and biological processes could aid in lowering the cost and achieving better yields. Furthermore, it is also observed that research on large-scale management and valorization of these aquatic plants also needs to be intensified.
