The increasing production of fly ash from coal combustion has become a problem due to the
environmental risks involved in its disposal. These wastes have a porous structure and …

The effect of trace elements (TEs) addition and NaOH pretreatment on the anaerobic
digestion of rice straw was investigated in batch tests. Co, Ni and Se were added to the raw …

Fe-bioavailability is an essential factor affecting CH4 production from anaerobic digestion
(AD). However, the actual uptake and utilization process of iron in complex microbial …

In this study, the anaerobic digestion of nitrogen-rich chicken manure from egg-laying hens
was investigated via long-term continuous experiments with and without the addition of …

Chemical speciation can fundamentally affect the potential toxicity and bioavailability of
heavy metals. The transformation of heavy metal speciation and change of bioavailability …

The effect of trace elements supplementation in anaerobic digestion of chicken manure (CM)
and their influence on methanogenic population dynamics were assessed at total ammonia …

The effect of biochar addition on the anaerobic digestion (AD) of food waste was evaluated.
From the five biochars tested, Fe, Co, Ni, and Mn were leached in very small quantities (< 10 …

The aim of this study was to investigate the impact of biochar addition on the mesophilic
semi-continuous anaerobic digestion of swine waste with a focus on the effects of the …

The current study presents a technical and economic evaluation of biogas production from
swine manure in the Southern of Minas Gerais, Brazil. For the study, laboratory-scale …

Due to the complex biogeochemistry of trace elements (TEs, eg Fe, Ni and Co) in anaerobic
digestion processes, their role and fate is poorly understood. Challenging, time consuming …
