“…Bioleaching of bottom ash (BA) and fly ash (FA) with a mixed culture isolated from a natural system showed good yields of metal extraction, with more than 90% Zn, Cu, and 10% Pb removed from FA; while 100% Cu, 80% Zn and 20% Pb were removed from BA samples (Funari et al, 2019). Bioleaching of bottom ashes with pure cultures Acidithiobacillus ferrooxidans or Leptospirillum ferrooxidans, or a mixture of Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans in batch tests showed that Al, Cr, Cu, Ni, Mn and the rare earth elements Ce, La, and Er were significantly more extracted with iron-oxidizing bacteria compared to abiotic controls (Auerbach et al, 2019). The results are encouraging for industrial application to recover concentrated metals like Al and Cu, simultaneously reducing the cost of landfilling the remaining residues.…”

“…Nevertheless, bioleaching can be a flexible and environmentally friendly alternative for conventional processes, as it allows the recovery of valuable resources, but can also reduce the toxicity of the waste for further reuse in other applications (e.g. aggregate materials) (Auerbach et al, 2019).…”

“…Table 1 summarises a SWOT analysis for the use of bioleaching for metal recovery from MSWI fly ashes and bottom ashes. (Auerbach et al, 2019). Bioleaching is a fully developed technology (TRL 9 for primary ores), and has been used at industrial level since 1960 for extraction of copper from sulphide ores.…”

“…It is beyond the scope of this study to provide a comprehensive review of the latest developments of bioleaching. In recent years, there has been an increasing amount of literature on bioleaching, with several extensive reviews covering the topic (Auerbach et al, 2019;Pollmann et al, 2018;Sethurajan et al, 2018;Srichandan et al, 2019). Our objectives are to focus on practical aspects and limitations that remain obstacles for the full implementation of bioleaching as a crucial tool for the circular economy.…”

Bioleaching (or microbial leaching) is a biohydrometallurgical technology that can be applied for metal recovery from anthropogenic waste streams. In particular, fly ashes and bottom ashes of municipal solid waste incineration (MSWI) can be used as a target material for biomining. Globally, approximately 46 million tonnes of MSWI ashes are produced annually. Currently landfilled or used as aggregate, these contain large amounts of marketable metals, equivalent to low-grade ores. There is opportunity to recover critical materials as the circular economy demands, using mesophile, moderately thermophile, and extremophile microorganisms for bioleaching. A Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis was developed to assess the potential of this biotechnology to recover critical metals 2 from MSWI wastes. Bioleaching has potential as a sustainable technology for resource recovery and enhanced waste management. However, stakeholders can only reap the full benefits of bioleaching by addressing both the technical engineering challenges and regulatory requirements needed to realise and integrated approach to resource use.

“…The use of local resources (in situ resource utilization, ISRU) could decrease the reliance of bioprocesses on Earth-imported materials and, thus, improve their cost-effectiveness. Researchers and engineers are, for instance, designing ways of growing plants on lunar or Martian analogue substrates (Lytvynenko et al, 2006;Zaets et al, 2011;Duri et al, 2020), possibly after processing them using microorganisms to release nutritive elements (Auerbach et al, 2019;Castelein et al, 2021).…”

Humankind has entered a new era of space exploration: settlements on other planetary bodies are foreseen in the near future. Advanced technologies are being developed to support the adaptation to extraterrestrial environments and, with a view on the longer term, to support the viability of an independent economy. Biological processes will likely play a key role and lead to the production of life-support consumables, and other commodities, in a way that is cheaper and more sustainable than exclusively abiotic processes. Microbial communities could be used to sustain the crews’ health as well as for the production of consumables, for waste recycling, and for biomining. They can self-renew with little resources from Earth, be highly productive on a per-volume basis, and be highly versatile—all of which will be critical in planetary outposts. Well-defined, semi-open, and stress-resistant microecosystems are particularly promising. An instance of it is kombucha, known worldwide as a microbial association that produces an eponymous, widespread soft drink that could be valuable for sustaining crews’ health or as a synbiotic (i.e., probiotic and prebiotic) after a rational assemblage of defined probiotic bacteria and yeasts with endemic or engineered cellulose producers. Bacterial cellulose products offer a wide spectrum of possible functions, from leather-like to innovative smart materials during long-term missions and future activities in extraterrestrial settlements. Cellulose production by kombucha is zero-waste and could be linked to bioregenerative life support system (BLSS) loops. Another advantage of kombucha lies in its ability to mobilize inorganic ions from rocks, which may help feed BLSS from local resources. Besides outlining those applications and others, we discuss needs for knowledge and other obstacles, among which is the biosafety of microbial producers.
