Batch experiments were conducted for feces composting using an aerobic composting reactor with sawdust as bulky matrix. In the 14-day composting processes at 35±2 and 55±2°C, compost samples were collected daily and chemical analyses and PCR-DGGE were carried out for investigating the influence of composting temperature on organic
Mar 19, 2019 · The final GI of the cylindrical reactor with an airflow rate of 0.3 L min −1 kg −1 DM was 82.3%, whereas the GIs of the other compost reactors were below 80%. In this study, compost of a cylindrical reactor with a low aeration rate (0.3 L min −1 kg −1 DM) was more stable and mature than the other reactors.
Sep 1, 2022 · Composting technologies have come a long way, developing from static heaps and windrow composting to smart, artificial intelligence-assisted reactor composting.
Nov 10, 2023 · Composting is a biochemical as well as a heterogeneous process, and the turning operation is important to maintain aerobic conditions and improve the efficiency of the composting process. Therefore, the turning frequency is an important factor for the precise control of the composting reactor. It is necessary to determine the changes in the physical and chemical parameters of the composting
With compost reactors with integrated heat recovery technologies, the green wastes 10 and the investments by a factor of 100 comparing low tech and high tech variants [11].
Jul 23, 2013 · The present study evaluates working performance of rotary drum reactor (RDR) and aerated In tank (AIV) for composting of garden waste. 100 kg garden waste was mixed with 10 kg cow-dung slurry
Nov 11, 2022 · Composting is one of the forms of organic solid waste disposal due to its environmental compatibility. Recently, composting has been obtained by the use of facultative reactors. The objectives of this review are to present recent research on facultative composting, focusing on mechanisms, substrates, process amelioration, economy, and environmental impacts. The study describes how
Apr 18, 2021 · How-to for a No-Turn Composting System that produces a SUPERIOR, microbially-diverse and fungal-dominant compost. This compost can be used to restore biological functionality to soils from small to large farming operations and from simple to advanced agroecosystems.
Mar 28, 2015 · In this study, high-load compost leachate was successfully treated in a hybrid anaerobic baffled reactor (ABR)/electrocoagulation-flotation (ECF) system. The interaction effects of operational factors in ABR, i.e., influent chemical oxygen demand (COD), hydraulic retention time (HRT), and COD/nitrogen (N) ratio on the efficiency of COD removal and biogas production rate (BPR) were analyzed and
Aug 2, 2023 · Vermicompost is so potent that one tablespoon can feed a medium-sized houseplant for more than two months. Lomi Kitchen Composter. $499. Lomi. $379. Amazon. Here’s another high-tech kitchen
Jul 23, 2013 · A pilot-scale composting reactor was developed, manufactured, and tested to enhance the biologically heated drying of high-moisture ingredients while minimizing bulking amendment requirements. This biodryer consists of two horizontal cylindrical chambers with internal augers for mixing, materials transport, and aeration.
Jun 6, 2023 · Fortunately, these barriers proved manageable with just two modifications to the original Johnson-Su design: 1. Shrinking the height of the bioreactor by half, from 5’ to 2.5’, to reduce the amount of feed materials required (an even smaller 2’ tall x 2’ diameter bioreactor should also work, but results from that scale are pending), and.
Feb 1, 2024 · The high positive cohesion indicated that the potential positive interaction of microorganisms was stronger, the level of OM converted into humus precursors was higher, and higher content of humic acid was easily formed (Fig. 6 e) (Zhao et al., 2022a). 4. Conclusions. A new composting reactor (PAVCR) was constructed.
The final GI of the cylindrical reactor with an airflow rate of 0.3 L min -1 kg -1 DM was 82.3%, whereas the GIs of the other compost reactors were below 80%. In this study, compost of a cylindrical reactor with a low aeration rate (0.3 L min -1 kg -1 DM) was more stable and mature than the other reactors. Implications: The poultry industry is
Apr 10, 2010 · Wang H B, Wang X C. Variation characteristics of sawdust as matrix in human feces composting reactor and its effect on microorganisms. Environmental Science & Technology, 2009, 32(3): 122–125 (in Chinese) Google Scholar Zavala M A, Funamizu N, Takakuwa T. Biological activity in the composting reactor of the bio-toilet system.
