To produce a valuable final product from anaerobic digestion (AD), one of the preferred methods organic recycling, high quality feedstock must be ensured. In this study, separately collected real biowaste (B) was used, consisting 90% food waste and 10% green waste. The priority issues AD are both methane production (MP) organics removal efficiency (as matter, OM dissolved organics, DCOD), which...

Steam explosion pretreatment of lignocellulosic biomass presents a promising technology for agricultural residues before anaerobic degradation. This study aimed to assess biogas production in continuously stirred tank reactors using steam-exploded maize stover mono-digestion. The continuous digestion tests were carried out four fermenters with capacity 150 L under mesophilic and thermophilic co...

The hyperthermophilic anaerobic bacterium, Caldicellulosiruptor bescii, is effective in degrading and solubilizing lignocellulosic materials. Laboratory studies have characterized the chemistry of process for crystalline cellulose switchgrass, but data are insufficient engineering commercial plants to use C. bescii pre-digestion waste streams. purpose this study three-fold: 1) identify any pote...

This study was undertaken to evaluate the efficiency of a liquid-solids separation process and microwave pretreatment, as well as anaerobic biodegradability of microwave pretreated dairy manure. Liquid-solids separation of raw dairy manure resulted in solid and liquid fractions having different properties, with the solid fractions richer in total and volatile solids content and liquid fractions...

Co-digestion has drawn much attention because of its potential to increase biogas production among other benefits. Restaurant grease has high energy content and methane production potential and so is a promising substrate for co-digestion with municipal wastewater sludge. Anaerobic co-digestion of municipal wastewater sludge and restaurant grease was investigated at laboratory-scale under mesop...

In order to obtain basic design criteria for anaerobic digesters of swine manure, the effects of different digesting temperatures, temperature shocks and feed loads, on the biogas yields and methane content were evaluated. The digester temperatures were set at 25, 30 and 35 degrees C, with four feed loads of 5%, 10%, 20% and 40% (feed volume/digester volume). At a temperature of 30 degrees C, t...

To reduce the impact on environment and enhance sustainability of resources, it is necessary to promote strengthen use landrace cultivars that advocate regenerative agriculture. In this study, growth development as well anaerobic digestion (AD) six different cultivars, two commercial hybrids a public genotype Sorghum bicolor have been evaluated. The in general, presented greater heights, biomas...
