Nov 28, 2022 · Growing animal production results in a significant amount of waste, composed of manure, bedding, feed, feathers, etc., whose safe and cost-effective disposal becomes a troublesome challenge. The literature review points out that the higher heating value (HHV) of animal-origin waste reaches 19 MJ/kg (dry basis), which positions it as a promising renewable energy source. Various paths of energy
Jan 1, 2021 · The fate of antibiotic resistance genes in cow manure composting: shaped by temperature-controlled composting stages ARGs, including tetC, tetG, and tetW, were enhanced by 198.77 %, 846.77 % ...
Apr 15, 2021 · Considering the probable risk, improved and adaptable technologies are urgently needed to control antibiotic resistance efficiently. This study monitored how thermophilic aerobic composting affected the ARGs, as well as the bacterial diversity during the composting of cow manure spiked with sulfamethoxazole (SMX) at different concentrations.
Jun 1, 2023 · The inoculation of Bacillus subtilis into cattle manure and straw composting prolonged the thermophilic phase of composting by 1–2 days and accelerated compost maturation [8]. Bacillus was inoculated into rice straw could alter the bacterial community of compost, thereby promoting the lignocellulose degradation [23] .
Dec 1, 2022 · Industrial-scale aerobic composting of livestock manures with the addition of biochar: Variation of bacterial community and antibiotic resistance genes caused by various composting stages
4 Best Compost Machines for Beginner Composters - GreenCitizen. This Countertop Compost Machine Turns Scraps into Compost in . Mar 27, 2024 · The Lomi countertop compost machine makes turning kitchen scraps into compost the easiest thing ever.
Oct 15, 2023 · During composting, pH is a crucial indicator of microbial activity and population composition [51].The variation in pH values during composting is also shown in Fig. 1.At the start of the composting process (Day 0), the pH of BPA pile mixture was 4.3, known to be due to food waste acidification, which produces organic acids as well as some volatile acids of low-molecular-weight
Jan 1, 2024 · Livestock manure use in agriculture contributes to pollutants like antibiotic resistance genes (ARGs) and resistant bacteria. This practice could potentially facilitate ARGs development in soil ecosystems. Our study aimed to explore ARGs and bacterial communities in cattle manure from Ningxia beef cattle farms with varying breeding periods.
Turning manure is essential to composting manure. Turning compost incorporates oxygen into the system, homogenizes the pile and breaks up clumps. Turning allows more contact of manure with microbes. Producers have various ways to turn the pile. The two most common for turning compost are with a windrow turner (Figure 7) or bucket tractor.

Dec 5, 2022 · Fang et al. combined intermittent aeration with membrane covering for cattle manure composting and found that the combined process reduced CH 4 emissions by 99.89% compared to the control. Through the above studies, it was found that membrane covering can effectively improve the efficiency of carbon and nitrogen fixation in compost and reduce
Mar 15, 2024 · These large amounts of antibiotic residues in livestock manure induce antibiotic resistance in animal gastrointestinal microorganisms [2]. Antibiotics introduced into the environment induce the production of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs), which pose a risk to the environment and public health [3], [4].
Aug 14, 2022 · The addition of biochar could mitigate the bioavailability of heavy metals during livestock manure composting. However, the main action mechanism of biochar, such as how it worked, was ambiguous. Therefore, in this study, materials (biochar, alkali modified biochar, pretreated cotton ball) were added by embedding with nylon mesh bags to explore the adsorption performance of added materials and
