Jan 1, 2010 · carbon (straw or woodchips) can help alleviate this. T oo much carbon (C/N ratio more than 40-to-1) in a. compost pile can immobilize nitrogen and slows the. composting process (Coyne and Thompson
Feb 1, 2020 · This study investigated the use of supplements of Lactobacillus plantarum (L. plantarum), strains P-8 and LP-10, on the efficiency of sheep manure composting and the quality of the final product. The composting process lasted eight weeks and, during this time, changes in multiple physical-chemical parameters and the compost microbiome were
Aug 29, 2018 · It also leads to up to 50–60% of reduction in the volume and density of manure thereby making its transportation more energy efficient than that of non-composted manure . Anaerobic digestion: Anaerobic digestion of manure is the processing of manure to produce energy, mainly biogas. Anaerobic digestion of manure can be made more efficient
Mar 7, 2017 · Song et al. reported that As concentrations increased by 57% in cow manure compost and 36% in pig manure compost 31. However, the total As concentration is an overall pollution indicator but

Turning waste into treasure: Biosynthesis of value-added 2-O-α-glucosyl glycerol and d-allulose from waste cane molasses through an in vitro synthetic biology platform. Haichang Xu, Taian Yin, Bin Wei, Mingming Su, Hao Liang. Article 129982. View PDF.
Sep 1, 2022 · Another study reveals that an energy recovery system attached to an aerated static composting pile has an energy capture ranging from 17,700 to 32, 940 kJ/h with a compost vapor temperature range of 51–66 °C (Sokač et al., 2022). Enhancing compost production with energy recovery systems will improve circularity levels of both small- and
Jul 15, 2023 · Incineration has high efficiency in energy recovery, but can produce pollutants such as volatile organic compounds and dioxins, which contaminate the atmosphere (Xu et al., 2022b). Composting is a potential technology that may transform organic substances into stable fertilizers, making it a feasible solid waste recycling option (Xu et al., 2022c).
Jun 1, 1996 · Based on these time estimates, the researchers calculated annual operating costs for each composting method, including electricity and fuel, labor (at $5/hour), annual land cost for the compost site (for 2.1 acres), and costs of straw to mix with the manure (at $2,450 per year for 60-cows at 4 pounds/cow/day).
Jan 20, 2018 · Composting can reduce negative environmental impacts of manure management. • Compost production is a solution to the “surplus” problem of livestock effluents. • Composting promotes the economic and productive recovery of residual biomass. Abstract
Feb 1, 2018 · Compost mix is aerated by a windrow turner which is powered by a farm tractor (PTO). This combined composting procedure represents a low technology and medium labour approach and produces an uniform compost. In addition, pumps for insufflations is placed on mobile carts in order to reduce the cost of handling. 4.2.2.
Why Compost? Many horse owners and small livestock operations do not have access to sufficient land to make good use of manure by spreading. Composting provides another option for managing manure on the farm. Microorganisms in the compost pile, including bacteria and fungi, break down the organic components of manure and bedding into smaller particles while releasing carbon dioxide, water and
Jan 1, 2023 · Compost links with food-energy-water nexus as an alternative to chemical fertilizers that can be used for food production. However, its sustainability has been doubted and challenged because of the potential system defects, like the fugitive emissions of CO 2 , NH 3 and H 2 S and the loss of carbon and nitrogen during treatment processes [15
Jul 19, 2018 · The conversion of horse manure-based substrate during composting and vegetative growth of A. bisporus has been studied in detail (Jurak et al. 2015b). Dry mass of the substrate is reduced by 8% in phase I of composting, by another 15% in phase II, ultimately resulting in a loss of 31% after 16 days of vegetative growth of A. bisporus (i.e., end
