The chemical industry aims to reduce its greenhouse gas emissions (GHGs) by adopting biomass as a renewable carbon feedstock. However, biomass is a limited resource. Thus, biomass should preferentially be used in processes that most reduce GHG emissions. However, a lack of harmonization in current life cycle assessment (LCA) literature makes the identification of efficient processes difficult

In addition, the chemical oxygen demand (COD), whose values are between 70.35 ± 4.47 and 80.82 ± 1.59 g.L −1 for the substrates subjected to AcoD, measures the content of oxidizable compounds in the substrate and theoretically enable predicting methane production as 1 g of converted COD corresponds to a maximum of 350 mL of methane . In the

This common pattern offers an general perspective on metabolism, making its purpose simpler to perceive. Stoichiometry b is the measurement of the amounts of chemical elements and molecules concerned in chemical reactions (from the Greek stoicheion, meaning "factor," and metria, that means "measure").
