Oct 1, 2023 · The current study explored bioenergy, particularly biohythane (a combination of biohydrogen (bioH2) and biomethane (bioCH4)), production from cow dung and untreated domestic wastewater sludge to valorize the waste into a value-added product. The experimental study consisted of a two-step process: dark fermentation (DF) and anaerobic digestion (AD) with a range of processing conditions varying

Nov 30, 2023 · Organic and natural farming is based on the use of indigenous fermentation technologies, like bioformulations based on cow dung and liquid manures. Cow dung is an essential and integral component of all these preparations and serves as a source of inoculum for beneficial microorganisms.

Oct 22, 2022 · The collected fresh cow dung used as a substrate in the study was from a dairy farm at Fort Hare University . With the ratio of 1:1 (waste/water), the slurry was obtained by the

Jul 27, 2023 · Traditional cow manure composting equipment often lacks ventilation, heating, and real-time monitoring and adjustment capabilities, hindering manure maturation and proper utilization of compost,

Sep 19, 2016 · The effects of cabbage waste (CW) addition on methane production in cow dung and corn straw co-fermentation systems were investigated. Four experimental groups, each containing 55 g of substrate

Jan 1, 2023 · Dry hydrogen fermentation of cow dung in laboratory-scale batch experiments was reported by Yokoyama, Waki, Ogino, Ohmori, and Tanaka (2007) and observed dry-fermentation process with butyrate and acetate formation at 60 °C, producing 743 mL H 2 /kg of cow dung.

Oct 8, 2020 · Recently, dry anaerobic co-digestion is one of the mechanisms which have been increasingly used to improve the reactor’s performance for treating livestock manure with agricultural crop residues. Due to carbohydrate, protein and lipid existing in agricultural wastes, biogas yield decreased with higher reactor volume when using wet anaerobic digestion. In this regard, the aim of this work was

Energy and Power 2017, 7(2): 37-40 DOI: 10.5923/j.ep.20170702.01 Biogas Production from Blends of Cow and Fowl Dung Using Locally Made Anaerobic Digester

Aug 1, 2023 · The cow manure was collected from a local dairy farm in Lanzhou, China. The total solid (TS) and volatile solid (VS) of cow manure was measured. Cow manure samples were used as AD substrates. The batch reactors were 250 mL glass bottles with a working volume of 200 mL. The cow manure substrate itself was used as the inoculum in the AD system.

Feb 10, 2021 · Results imply that co-digestion and pretreatment approaches gain the predominance on promoting the digestion performance of cow manure. Particularly, for the co-digestion scenario, the selection of lignin-poor co-substrate is highlighted to produce maximum synergy and pronounced removal of lignocellulosic compounds of cow manure.

Mar 22, 2022 · Lignocellulose degradation (LCD) was the key factor limiting the development of anaerobic fermentation (AF) by the cow dung (CD). In the research, the effects of cellulase pretreatment (CP) and microvoltage (MV) alone and combination on the gas production and LCD during the AF were investigated. The results showed that both CP and MV had an significant effect on the AF, though the synergistic

Feb 14, 2024 · Anaerobic co-digestion of organic wastes and plant biomass generates an environmentally friendly energy source. Anaerobic co-digestion of cow dung (CD), goat manure (GM), and cactus cladodes (CC) was investigated under mesophilic laboratory conditions. A 14-day-long daily biogas production potential and methane content were evaluated for the three substrates co-digested at different mix ratios

Jun 22, 2024 · This difference in duration may be attributed to the respective compositional properties of cow and sheep manure affecting fermentation efficiency. Comparatively, whole sheep manure, sheep manure mixed 1:1 with cow manure, and sheep manure mixed 1:2 with cow manure followed each other in their respective complete putrefaction cycles.

May 12, 2024 · The world population’s rapid growth has led to a surge in solid waste production, posing complex waste management challenges. This study explores the use of food waste for biogas production through anaerobic digestion, offering a sustainable solution. Anaerobic bacterial consortia were utilized to produce biogas from vegetable waste, banana peels, and cow dung. Proximate analysis revealed

Sep 5, 2023 · Composting the cow manure in the fermentation grooves is simple. However, this is done before the process of natural decay. Composting is different than collecting cow dung and piling it in a tank. You must use a cow dung composting machine with grooves to transform the raw materials. How to Apply Cow Manure Fertilizer to the Crops?
