Environmental impact of microbial protein from potato wastewater as feed ingredient: Comparative consequential life cycle assessment of three production systems and soybean meal

Responsible science, engineering and education for water resource recovery and circularity

“…Systems thinking in an expanded control volume along with sustainability economics, decision making, and relevance for real-word application should help to address the benefits and impacts of resource recovery in the ecological balance, societal setting, and circular economy. Techno-economic analyses, life cycle assessment and costs analyses 18,19 are dedicated methods to this end. They can be efficiently complemented by stakeholder analyses, game tools and scenario investigations as well as ethics, decision, and policy-making seminars.…”

Cocultivating aerobic heterotrophs and purple bacteria for microbial protein in sequential photo- and chemotrophic reactors

“…Microbial protein production on synthetic media is mainly dominated by axenic fermenter technology, which enables culture specificity (Najafpour, 2015). On the other hand, the production of microbial protein for resource recovery is usually performed with non-axenic heterotropic cultures such as aerobic heterotrophic bacteria (AHB), purple non-sulfur bacteria (PNSB) and consortia of microalgae and AHB (Spiller et al, 2020).…”

Metagenomic Insights Into Functional and Taxonomic Compositions of an Activated Sludge Microbial Community Treating Leachate of a Completed Landfill: A Pathway-Based Analysis

“…Among targeted sites amenable to MRM applications, bioreactors treating industrial water and wastewater, e.g., waste produced during food processing and by livestock industries (Matassa et al, 2015;Spiller et al, 2020) and landfill leachate, are promising. From a societal perspective, the demand for appropriate leachate treatment is expected to surge as the amount of waste increases from 2.0 billion tons in 2016 to an expected 3.4 billion tons by 2050 (Kaza et al, 2018).…”
