“…The above-reviewed examples indicate that the concept of linking phytoremediation and thermochemical biofuel production is a potential and promising pathway toward sustainability, valorizing the polluted biomass into metal-free biofuels and by-products, while allowing the recovery of HMs. Besides the benefits of producing bioenergy from polluted biomass, the generation of potentially toxic streams must be minimized [91,92], which has focused the investigation of sorbents, demineralization, and leaching techniques in order to remove or immobilize HMs.…”

Phytoremediation is an attractive strategy for cleaning soils polluted with a wide spectrum of organic and inorganic toxic compounds. Among these pollutants, heavy metals have attracted global attention due to their negative effects on human health and terrestrial ecosystems. As a result of this, numerous studies have been carried out to elucidate the mechanisms involved in removal processes. These studies have employed many plant species that might be used for phytoremediation and the obtention of end bioproducts such as biofuels and biogas useful in combustion and heating. Phytotechnologies represent an attractive segment that is increasingly gaining attention worldwide due to their versatility, economic profitability, and environmental co-benefits such as erosion control and soil quality and functionality improvement. In this review, the process of valorizing biomass from phytoremediation is described; in addition, relevant experiments where polluted biomass is used as feedstock or bioenergy is produced via thermo- and biochemical conversion are analyzed. Besides, pretreatments of biomass to increase yields and treatments to control the transfer of metals to the environment are also mentioned. Finally, aspects related to the feasibility, benefits, risks, and gaps of converting toxic-metal-polluted biomass are discussed.

“…This effectiveness was not limited to employment capabilities alone but included education, maintenance, sustainability, environmental considerations, and ability to requisition components of the systems in each location. Xiong et al (2019) considered the transport and ultimate fate of various potentially toxic compounds and chemicals. This research looked at the spatial distribution of various pollutants of interest in solid waste streams and considers applicable abatement approaches in reducing their incidence in the environment.…”

“…Several soil detoxification methods such as stabilization, containment, and solidification etc. have been offered for the in-situ remediation of contaminated soils, but the high-risk involvement and high cost of remediation [9] emphasizes the scope of bioremediation through novel As-tolerant microbes [10]. Bioremediation through novel As-tolerant microbes may be an easy, eco-friendly, low cost and emerging approach to mitigate arsenic contamination.…”
