The role of additives on anaerobic digestion: A review

Treatment technologies for urban solid biowaste to create value products: a review with focus on low- and middle-income settings

“…slaughterhouse waste), energy crops and harvesting residues (incl. algae), and the organic fraction of municipal solid waste (Romero-Güiza et al 2016). As AD typically occurs in an aqueous environment, feedstock with high moisture contents (even containing more than 60% water) can be processed without pre-treatment (Appels et al 2011).…”

“…More on AD process inhibition due to ammonia, sulfide, light metal ions, heavy metals and other compounds is discussed in Chen et al (2008), Zhao et al (2010) and Yenigün and Demirel (2013). A review on the issue of instrumentation and process control can be found in Jimenez et al (2015), on mathematical models for both simulation and control purposes in Lauwers et al (2013), and on recent advances in the utilization of inorganic and biological additives to improve digester performance in Romero-Güiza et al (2016).…”

Biomethane production tests on ensiled orange peel waste

“…One of the most promising options is the use of OPW as a substrate for methane production through the anaerobic digestion process [5][6][7][8][9][10][11][12][13][14][15][16]. This is a biochemical process which consists in the decomposition of complex organic substances, contained in the biomass, into a gas, basically composed of methane and carbon dioxide, and used as a biofuel.…”

Trace element supplementation as a management tool for anaerobic digester operation: benefits and risks

“…As described above, feedstocks have different content in TE and some might be rich in one or more elements. The use of a co-digestion system may naturally equilibrate the nutrient availability and enhance AD performances (Zhang et al 2011;Romero-Güiza et al 2016). The main advantage of co-digestion is to bring a synergy between two/three compatible feedstocks in term of overall nutrient supplementation (including TE) with a low cost.…”
