Jun 19, 2023 · The first axis aimed to characterize the different components of the horse waste (horse manure (HM), wheat straw (WS), wood chips (WC)) regarding their biochemical composition, biochemical methane potential (BMP) and physicochemical characteristics (density, humidity, total solids and volatile solids).

Biogas from Manure: The Future of Renewable Natural Gas and

Apr 29, 2023 · Co-digestion improved nutritional balance and diluted high NH3 concentrations in swine manure, resulting in improved digester performance efficiency and increased biogas production (Li et al. 2014). The co-digestion of swine and poultry manure in a ratio of 1:1 (w/w dry basis) was reported to significantly enhance biogas production compared

Generation of High Concentration Free Volatile Fatty Acids

Oct 18, 2023 · Free volatile fatty acids (free VFA) play a crucial role in the inactivation of pathogens during the anaerobic digestion of animal manure. However, the decomposition of nitrogenous components can release alkaline ammonium-N, which might increase the pH and reduce the concentration of free VFA. In this study, continuous anaerobic digestion of high-solid chicken manure was conducted for 150 days

Strategies to boost anaerobic digestion performance of cow

Feb 10, 2021 · Highlights. •. The lignocellulose of cow manure hinders a good methane yield in anaerobic digestion. •. Biological pretreatment (composting) of cow manure is promising in full-scale application. •. Selection of a lignin-poor co-substrate is vital when conducting co-digestion trials. •.

Fermented Leaf Fertilizers—Principles and Preparation

Aug 6, 2019 · Fermented leaf fertilizers (FLF) are made of anaerobically fermented plant and/or animal resources and principally used for foliar plant nutrition, as they provide a quick nutrient supply

Influence of pH controlling on fermentation performance in

Sep 17, 2019 · ABSTRACT. In order to make the process more sustainability and more efficient in co-digestion of kitchen waste (KW) and cow manure (CM), the effect of pH controlling at initial fermentation time (I), first gas stagnation time (A), and combination of both times (C) were investigated.

Horse Poop: The Complete Guide to Horse Manure - Equineigh

What are the uses of horse manure? Horse manure is rich in vital minerals that help keep soil fertile. If you plan to use horse manure as fertilizer, make sure to spread the stuff in an area or pasture where your horses don’t graze. This keeps them from consuming their own excrement. Manure tea works wonders to fatten up soil used for

How Does Hindgut Fermentation Work in the Horse? | Mad Barn

Jun 12, 2023 · Horses are single stomach (monogastric) herbivores that evolved to graze on fiber-rich roughage. Their unique digestive system consists of a foregut and hindgut, each with different functions for breaking down feed and absorbing nutrients. The stomach and small intestines, which make up the foregut, are responsible for digesting proteins, fats, and non-fibrous carbohydrates in the horse's diet

Animal Manure for Soil Fertility | SpringerLink

Land application of animal manure as fertilizer includes numerous strategies considering the different combinations of manure composition, crop system, soil type and composition, and farm management constraints (e.g., financial, personal, regulation, or others) (Meisinger and Jokela 2000).

Energies | Free Full-Text | Pretreatment of Animal Manure

Jul 10, 2020 · The objective of this research is to present a review of the current technologies and pretreatments used in the fermentation of cow, pig and poultry manure. Pretreatment techniques were classified into physical, chemical, physicochemical, and biological groups. Various aspects of these different pretreatment approaches are discussed in this review. The advantages and disadvantages of its

Frontiers | Livestock Manure Type Affects Microbial Community

The higher content of TN in pig and chicken manure composts was likely due to high protein contents in their feed (Chen et al., 2019), while higher TC contents and C/N ratios observed in sheep and cattle manure composts could be indicative of the presence of cellulose substances or unutilized complex nitrogen substrates in their feed (Pan et al

Manure-based biogas fermentation residues – Friend or foe of

May 1, 2015 · Very often, sludges from WWTP are either deposited in waste dumps, or are incinerated. Sludges from WWTP are not the focus of this review. However, most recently, in many places operators of WWTP realised that the capacities in their anaerobic fermenters are high enough to allow for co-substrates from other sources than from the wastewater stream.

Biogas production of Chicken Manure by Two-stage fermentation

However, the high content of free ammonia (NH3, main part of total NH 4 +-N) in the fermentation liquid would inhibit methanogens and reduce the methane production [4]. Among all kinds of livestock and poultry manure, chicken manure contains relatively high content of nitrogen as well as the low carbon to nitrogen ratio
