eco livestock manure composting machine for high efficiency

Apr 27, 2021 · The purpose of the present study was to verify the previously reported conclusion by Kitamura et al., i.e., that cattle manure compost exhibits the ability to remove ammonia. Moreover, we previously compared food waste compost with cattle manure compost to reconsider the recyclability and usability of kitchen refuse generated in urban areas.

Mar 1, 2018 · Biological and chemical properties in livestock manure can be significantly altered by the composting process, primarily due to the high temperature (60–65 °C) and oxygen supplement. Microbial activities related to organic matter decomposition decline rapidly between 60–65 °C ( Bernal et al., 2009 ), and most of the methanogenic archaea

Apr 30, 2024 · Livestock manure is one of the most important pools of antibiotic resistance genes (ARGs) in the environment. Aerobic composting can effectively reduce the spread of antibiotic resistance risk in livestock manure. Understanding the effect of aerobic composting process parameters on manure-sourced ARGs is important to control their spreading risk. In this study, the effects of process

Nov 1, 2024 · The four scenarios have been constructed as follows: Scenario 1 is based on the livestock manure utilization rate in 2015, Scenario 2 on the utilization rate in 2020, Scenario 3 on policy projections for manure utilization in 2025, and Scenario 4 on our assumptions for the limit values of livestock manure utilization rates in 2025 in China (Wei

Due to the high demand for food and meat for the world's growing population, the agricultural sector is expanding every year. Timely and effective treatment is of utmost importance to utilize organic matter in agricultural waste and avoid environmental pollution. Composting or aerobic fermentation is an effective way to treat agricultural waste and produce organic fertilizer. Improving the

Apr 15, 2024 · The objectives of this study are as follows: (1) to analyse the eco-efficiency of different modes with coupling crop and livestock production farms and optimize their economic efficiency and carbon emission intensity; (2) to explore the impact of farmland on the development of farms with integrated farming systems; and (3) to elucidate the

Sep 1, 2024 · The ratio of livestock manure to recycled compost was 1:1 according to fresh mass weight. Recycled compost derived from wastewater sludge from Kagoshima city was used as the hyperthermal compost (Tashiro et al., 2016). The moisture content of the starting mixture (pig feces and recycled compost) was 43.5%, and no additional water was added

The effectiveness of newly isolated ammonia-oxidizing bacteria (AOBs; T-AOB-2, M-AOB-4 and MT-AOB-2-4) in promoting organic matter degradation and humification of cattle manure compost was explored. The results show that, compared with the control, the inoculation of AOBs (5%, v/w) promoted the humi

Feb 8, 2024 · This study proposes a novel approach that exhibits high eco-efficiency in the treatment of OSWs. With the increase of organic solid wastes (OSWs), current waste management practices, such as landfill, incineration, and windrow composting, have shown we

based on its high surface area and porosity, is commonly used to enhance the composting process (Zhou et al. 2019). Mature com-post is another option for compost amendment and can introduce favorable microorganisms to the compost (Liu et al. 2018b). In practical organic fertilizer production, the composts are typically

Aug 15, 2024 · The Chinese government has introduced a range of policies (Hu et al., 2019), including Regulations on Pollution Prevention and Control of Livestock Scale Farming (SCOPRC, 2013), Action Plan for the Resource Utilization of Livestock Manure (2017–2020) (MOA, 2017) and the Implementation Plan for Agro-Agriculture Emission Reduction and Carbon Sequestration (MOA, 2022), which are aimed at

Oct 1, 2020 · In accordance to our study, mature compost inoculation extended the high thermophilic period in cattle manure composting (Ma et al., 2019). A germination index (GI) greater than 80% is considered an indicator that compost is mature and phytotoxicity-free (Zhang et al., 2018).

Cattle manure and rice straw collected from a cattle farm and local residents in Dalian, China, were used as the raw materials for the present study of aerobic composting. Rice straw, used to adjust the water content and suitable C/N for composting, was mixed with fresh cattle manure at a ratio of 1:10 in fresh weight and then composted in a

Apr 1, 2022 · A theoretical model is proposed to explain the mechanism of improving composting efficiency by adding mature compost (Fig. 5). In the mesophilic stage, mature compost addition inoculated bacteria related to maturity, increased the diversity of bacterial community and promotes the start of composting.
