Накратко на български

Микроорганизмите в биореакторите се анализират, за да се разбере как превръщат хранителни отпадъци в биогаз или биопластмаса. Това помага за по-ефективното преработване на отпадъците и производството на възобновяема енергия.

Friends or foes? The role of Biofilm microbiomes in industrial anaerobic membrane bioreactors to MAXimise bioenergy production

The industrialization, urbanization and centralization of modern societies have led to rising demands of energy and resources, accompanied by the production of large and persistent amounts of biodegradable waste and wastewater streams. These waste streams need to be managed, treated, reused, or disposed adequately to decrease the detrimental effects on the surrounding environment and human health. European Union (EU) directives, United Nations sustainable development goals, and an increasing number of individual citizens are advocating for a systematic change towards resource recovery schemes. Transforming waste and wastewater into renewable energy, clean water and add-value products achieves these goals with a threefold benefit by reducing environmental impact, offsetting raw materials demands and promoting circular bioeconomy markets. As part of this mission, the EU Best Available Techniques reference documents on Industrial Emissions (Directive 2010/75/EU) recommends energy-producing anaerobic biotechnologies for the treatment of biodegradable waste streams. Anaerobic biotechnologies are a mixed-culture microbial-mediated process that transforms biodegradable organic compounds into renewable energy in the form of methane-rich biogas or add-value compounds such as volatile fatty acids that can be used to produce bioplastics. To promote the widespread adoption of anaerobic biotechnologies for the valorization of biodegradable waste streams, the objective of this action was to quantify the distinctive role of beneficial microbes to improve the performance, robustness, and economic feasibility of anaerobic biotechnologies. To this aim, the action identified process-critical microorganisms to produce add-value compounds from anaerobic fermentation from food waste and sewage sludge, and their relationship towards process optimization laying the foundations to develop and improve microbial management strategies.

Цел на проекта

Transforming the European Union into a competitive low-carbon economy by 2050 requires the industry sector to continue implementing energy-efficient processes, especially for the valorisation of biodegradable waste and wastewater. Anaerobic digestion membrane bioreactors (AnMBR) is an emerging technology combining the production of methane-rich bioenergy and high-quality effluents free of particles, colloids and pathogens. However, the presence of biocidal or inhibitory compounds found in many industrial wastewaters hinders the implementation of AnMBR associated to low process efficiencies and instability. Additionally, the adhesion of particles and formation microbial biofilms into the membrane surface results in increased operational energy requirements. Biofilm formation may be exacerbated when treating industrial wastewaters containing high concentrations of inhibitory compounds since biofilm formation is a widespread microbial survival strategy to thrive under unfavourable conditions. However, are biofilms friend or foe? A controlled biofilm formation may be beneficial to improve AnMBR robustness and methane yields since the protection given by the biofilm structure allows microorganisms to function in harsher conditions. Understanding the interaction between biofilm formation and functionality in anaerobic biotechnologies is key for the success of AnMBR technology and the valorisation of heavily polluted industrial wastewaters. To this aim, I will systematically study the identity, dynamics and ecophysiology of planktonic and biofilm microbiomes occurring in AnMBR treating pharmaceutical wastewater. Harnessing this knowledge will allow the quantification of the role and potential of microbial biofilms to improve AnMBR performance, robustness and economic feasibility. The experience gained from combining microbial and engineering approaches will lay the foundations to develop and improve biofilm management strategies for a successful AnMBR implementation.
