anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...

Kinetic models which can express the behaviors of hydrolysis and biogas generation more precisely than the conventional models were developed. The developed models were evaluated based on the experimental data of six batch reactors. Anaerobic digestion test was co-digestion of food and vegetable waste with inoculating horse dung by 15% of the total wet weight, at the temperature of 37o</su...

a digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. the experiment consisted in 4 periods and lasted 84 days. the total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...

BACKGROUND Anaerobic digestate is the effluent from anaerobic digestion of organic wastes. It contains a significant amount of nutrients and lignocellulosic materials, even though anaerobic digestion consumed a large portion of organic matters in the wastes. Utilizing the nutrients and lignocellulosic materials in the digestate is critical to significantly improve efficiency of anaerobic digest...

The Sustainable Value methodology was used to compare and rank eight combinations of waste biomass types conversion technologies on a common assessment basis produce energy, energy vectors advanced biofuels. studied included agricultural agro-industrial residues, slurries effluents, pulp paper mill sludge, piggery effluents organic fractions municipal solid waste, biodiesel by (trans)esterifica...

this experiment was conducted to investigate the digestibility and fermentation parameters of diets containing flower, pod with seed and leaf of siris in sheep by two-step digestion and gas production methods. the experimental diets were including zero, 25, 50, 75 and 100 percent of siris flower, pod and leaf. the result showed that gas production potential of diet containing 50 percent leaf wa...

In the last decades the increasing energy requirements along with the need to face the consequences of climate change have driven the search for renewable energy sources, in order to replace as much as possible the use of fossil fuels. In this context biomass has generated great interest as it can be converted into energy via several routes, including fermentation and anaerobic digestion. The f...

Two of the most important Mexican plant-foods are tomato (Solanum lycopersicum L.) and husk (Physalis ixocarpa Brot.). In this study three objectives were followed: i) to evaluate bioaccessible phenolic compounds (PC) in T HT during upper gastrointestinal digestion, ii) vitro ferment indigestible fractions samples short-chain fatty acids (SCFA) production, iii) microbial metabolites, bioconvert...
