Hydrodynamic cavitation (HDC) as a pre-treatment method is innovative and has potential for wide-scale industrial applications. The novelty of this research involves evaluating the enzymatic activity in the anaerobic co-digestion (AcD) of hydrodynamically cavitated coffee waste (CW) and municipal sewage sludge (SS) as well as its influence on the A...
The purpose of this study is to effectively support the operation of biogas plants that utilize anaerobic digestion of pig manure. An analysis was conducted on the characteristics of manure collected from 17 pig farms. Following this, the methane potential of the manure was evaluated, and a comparison of microbial communities was made at the end of...
This study explores the impact of incorporating conductive materials and bioelectrochemical systems (BES) on the efficiency of anaerobic digestion (AD) of sewage sludge. The research consists of two phases: biodegradability tests using 3D-printed polylactic acid-based conductive fillers (PLA/Carbon Black and PLA/Graphene) and semi-continuous assays...
Biochar-based additives can enhance the ability to produce methane during anaerobic digestion (AD), and biogas residues (BRs) are solid waste that can cause environmental pollution. Therefore, in this work, BRs were used as raw material to prepare biochar, and Fe3+ was used to modify biochar for use in the AD process, generating pig manure water (P...

Methane gas produced by livestock animals contributes significantly to greenhouse gas emissions and is a major environmental issue. However, the use of feed additives for controlling ruminal methanogenesis has emerged as a promising solution for reducing these emissions. Numerous studies have demonstrated that the use of feed additives such as biol...
Two-stage meso- and thermophilic anaerobic digestion (TSMTAD) of food waste was examined and its microbiological structure was investigated. The first stage was designed for the primary storage of perishable food waste and the second stage for central biogas production. Mesophilic storage with initial neutralization and inoculation of lactic acid b...
This study aimed to assess the efficacy of anaerobic digestion (AD) in the co-digestion of the organic fraction of municipal solid waste (OFMSW) and municipal dehydrated sewage sludge (DSS). The experiments were conducted in batch and continuous mode under mesophilic conditions (T = 37 ± 2 °C). The results of batch tests indicated that the use of D...
Bioplastics are designed to degrade at the end of their lifecycle, but effective management of their end-of-life phase and integration into existing organic waste management systems remain significant challenges. Some bioplastics decompose under anaerobic conditions, with the anaerobic digestion (AD) process being a potential solution for their dis...

Anaerobic digestion (AD) of feedstocks yields biogas, a potentially useful new energy source. This study looked into the anaerobic co-digestion of cow dung and organic garbage to produce biogas. An anaerobic biodigester, with a volume of 20 L, was used to digest organic waste (OW) and to trace the changes that occur during the AD process. It was eq...
Anaerobic digestion (AD) is one of the most significant processes for treating fecal sludge. However, a substantial amount of microplastics (MPs) have been identified in septic tanks, and it remains unclear whether they impact the resource treatment of feces. To investigate this, polyethylene terephthalate (PET) was used as an indicator of MPs to s...
