Similarly, BCs can be used to search for biological membranes or directed polymers that improve proton and ion transfer in fuel cells, thus enhancing performance and extending service life.
• Waste Treatment for Energy Production – Organic waste, such as sewage sludge, can serve as raw material for biogas production through anaerobic digestion. BCs assists in analyzing the complex microbial communities involved in anaerobic fermentation processes. Identifying the main bacteria and archaea (“ancient bacteria”) that contribute to methane production allows for optimizing process conditions and improving output. Moreover, changes in the microbial community structure can be monitored in real-time, and adjustments can be made accordingly. In this context:  
  • Efficient Biomass Degradation – Biomass, such as crop residues and wood waste, contains complex sugars like cellulose and hemicellulose that can be converted into biofuels. However, breaking down biomass into its essential components is a challenging process. BCs can be used to discover new enzymes from various microorganisms that efficiently degrade cellulose and hemicellulose. Thoughtful integration of these enzymes into biofuel production processes can enhance efficiency and reduce cost. 

However, implementing BCs technology to address climate change also presents challenges.
