Mar 7, 2021 · Organic solid waste is considered a renewable resource that can be converted by various technologies into valuable products. Conventional thermophilic composting (TC), a well-studied and mature technology, can be applied to organic solid waste treatment to achieve waste reduction, mineralization, and humification simultaneously. However, poor efficiency, a long processing period, as well as
Here, the impact of inoculation and turning for full scale composting on core bacterial community and their co-occurrence network as well as harmless level were compared by network analysis. Results showed that composts with both inoculation and turning had 46% increase of total organic carbon degradation compared to traditional composting and
Jul 8, 2022 · The higher fraction of the β phase could lead to enhanced corrosion resistance by increasing the charge transfer resistance through the double layer and reducing the rate of the dissolution
Jan 1, 2024 · In addition, EFAC is more costly than CAC and CCMC because of the electrode cost, and the corrosion resistance of the electrode plates must be considered due to corrosive composting materials (Fu et al., 2022b). Thus, it is necessary to perform material optimization to improve the suitability of EFAC for large-scale applications.
Results showed hyperthermophilic composting enhanced decomposition and humification of municipal sludge in the short terms, while heavy metal concentrations and speciation had no significant change with high copper and zinc levels (101-122 and 292-337 mg/kg, respectively) in compost samples.
Jan 5, 2021 · This study evaluated the microbial safety and antibiotic resistance risks of a sustainable ecological farm under large-scale open-air composting (OC) and green composting toilet systems (CT). Samples of livestock manure, compost, soil, vegetables, and rainwater were analysed to determine the best treatment of wastes and risk assessment of land
Sep 1, 2022 · A large-scale study involving data from 28 composting systems fed from commercial pig farms showed that reactor composting had the best results in terms of material degradation, nitrogen loss, antibiotics, and antibiotic resistance genes compared to conventional such static heap and windrow systems (Awasthi et al., 2019c, Awasthi et al
Nov 23, 2022 · Homogenous spatial distribution of fermentation characteristics, local anaerobic conditions, and large amounts of greenhouse gas (GHGs) emissions are common problems in large-scale aerobic composting systems. The aim of this study was to examine the effects of a semi-membrane covering on the spatial homogeneity and efficiency of fermentation in aerobic composting systems. In the covered group
Industrial composting technologies allow you to turn organic waste into compost on a much larger scale than you could ever achieve with a home composting system. To achieve this scale, specialised equipment and facilities are often used. There are several different and technologies that can be used for industrial composting, including
Mar 27, 2015 · Superhydrophobic 5052 aluminum alloy substrates with excellent corrosion resistance have been fabricated by a simple and low-cost method of acid treatment and modification of fluoroalkyl-silane combined with surface passivation. Via an etching process with hydrochloric acid, hierarchical convex–concave micro/nano-structures have been formed on 5052 aluminum alloy surfaces. Then they were
Mar 5, 2021 · The main contaminants of concern in manure are veterinary antimicrobials. A ten-year record (2009-2018) of the amount of veterinary antimicrobials sold in the U.S. for disease control (administered at therapeutic levels) and growth promotion (administered at sub-therapeutic levels) in food-producing animals alone have ranged from 10.9 to 15.6 million kg/year (Fig. 1) (USFDA, 2019a).
Blog ECS Staff 11/23/2021. Collectively, Engineered Compost Systems scientists and engineers have more than 120 years of experience successfully supporting large-scale composting systems. You could say we have the design, development, deployment, and maintenance of large-scale composting systems “down to a science.”.
Multiple types of biochemical parameters were determined in the course of the composting process with rice straw and Chinese traditional medicine residues as substrates. The water-soluble fractions (WSFs) were analyzed by excitation-emission-matrix fluorescence (EEM-FL), and the maximum P V/III value (1.2) was observed in thermophilic phase
Apr 15, 2024 · The enhanced localized corrosion resistance in AM stainless steels has been widely attributed to refinement of pit initiating MnS inclusions. Even though the mechanism of pit initiation around the MnS inclusions in stainless steels is different from that of nitrides in Ni-alloys, both share the trait of being preferential pit initiation sites
Apr 2, 2024 · Direct climate benefits of composting. Dumping food wastes and grass clippings in landfills generates large amounts of methane because the decomposition process is anaerobic. Landfills release about 17% of total U.S. anthropogenic methane emissions and food waste makes up 24% of landfill space. Burning organic wastes releases GHGs and toxins.
