Anaerobic digestion (AD) of waste activated sludge (WAS) is an important bio-energy
strategy that has been hindered by low conversion efficiency. This paper presents a …

When properly designed, pretreatments may enhance the methane potential and/or
anaerobic digestion rate, improving digester performance. This paper aims at providing …

This paper presents a review of the main sludge treatment techniques used as a
pretreatment to anaerobic digestion. These processes include biological (largely thermal …

During wastewater treatment, most organic matter is transferred to a solid phase commonly
known as sludge or biosolids. The high cost of sludge management and the growing interest …

Recent shifts in European countries biogas policies tend to limit the use of energy crops and
encourage the use of manure, lignocellulosic feedstocks and bio-waste. The need to use …

The main goal of this present study is to investigate the feasibility of coupling algae
production (Chlorella vulgaris) to an anaerobic digestion unit. An intermediate settling …

Thermophilic microaerobic pretreatment has been proved to be efficient in improving
methane production of corn straw in previous studies. In this study, the effect of mesophilic …

This article reviews the experimental and theoretical studies conducted on the possible
effects of oxygen in biogas generating anaerobic digesters. The interactions of oxygen with …

Microaerobic process has been proven to be an alternative pretreatment for the anaerobic
digestion (AD) process in several studies. In this study, the effect of thermophilic …

The present work investigated the potential of acidogenesis digestate rich in volatile fatty
acids (Bio-D Acid) and methanogenesis digestate rich in ammonia (Bio-D Meth) as a green …
