This study assessed the biosorption mechanisms of eight target emerging contaminants (ECs) in two anaerobic fixed-bed biofilm reactors (FBBR), one acidogenic (AcFBBR) and one methanogenic (MtFBBR), by depicting the lipophilicity (logKow / logDow), electrostatic interactions with biofilm and solid–water distribution coefficient (KD) of each compound...

Anaerobic digestion is a versatile biotechnology because of the energy recovery from different kinds of waste. In addition to anaerobic digestion, there is the anaerobic co-digestion process, which improves the energy recovery of many kinds of waste in a single installation. The association of landfill leachate and crude glycerin is promising, cons...

Due to the slow growth rate of anammox bacteria, enriched sludge is required for the rapid start-up of anammox-based reactors. However, it is still unclear if long-term stored anammox sludge (SAS) is an effective source of inoculum to accelerate reactor start-up. This study explored the reactivation of long-term SAS and developed an efficient proto...

Coffee is the second most traded commodity worldwide, and its production is associated with the generation of a large number of residues, which are underused and disposed of in landfills. Notably, the coffee industry annually generates approximately 6 million tons of industrial spent coffee ground (ISCG) when extracting coffee flavorings to produce...

Anaerobic digestion is a viable process to recover bioenergy through sugarcane vinasse in the form of methane. However, interruptions in the anaerobic reactors operation during the sugarcane off-season is clearly a challenge to the anaerobic systems’ performance, which potentially negatively compromise the energy balance in a sugarcane biorefinery....

Ethanol and biodiesel industries generate large volumes of by-products, such as vinasse and glycerol, which are suitable for biogas exploitation. This paper assessed the applicability and process performance of the anaerobic structured-bed reactor (AnSTBR) for the mesophilic (30 °C) continuous (105 days) anaerobic co-digestion of sugarcane vinasse...

Understanding co-digestion technologies from biofuel residues, such as vinasse and glycerol, is an important step in the search for operational improvements in anaerobic systems, enhancing energy recovery through biogas production. This study investigates the methane production from the mesophilic (30 °C) co-digestion of sugarcane vinasse and disti...

Anaerobic digestion is a versatile biotechnology that produces bioenergy, biogas, from wastewater. Biogas production and wastewater treatment can be optimized by associating substrates with complementary characteristics. In this context, the aim of this study was to evaluate the performance of the anaerobic co-digestion of different contents of lan...
