Jun 22, 2020 · Over the last decade, food waste has been one of the major issues globally as it brings a negative impact on the environment and health. Rotting discharges methane, causing greenhouse effect and adverse health effects due to pathogenic microorganisms or toxic leachates that reach agricultural land and water system. As a solution, composting is implemented to manage and reduce food waste in
Dec 22, 2020 · An innovative biodrying-enhanced composting (BEC) system that applies biodrying to composting process as its start-up stage was developed to rapidly process kitchen waste (KW) into highly maturate
Feb 1, 2024 · Moreover, Fe2+ slightly inhibited the overall microbial activity during food waste composting (Pan et al., 2023a). This might be attributed to lower pH and higher EC in the early stages of composting. The microenvironment was weakly alkaline and EC value was in the standard range at the later stages, and maturity of compost was higher.
The harmless and high-value conversion of organic waste are the core problems to be solved by composting technology. This study introduced an innovative method of promoting targeted humification and nitrogen retention in composting by adding p-benzoquinone (PBQ), the composting without any additives was set as control group (CK).
Feb 7, 2022 · Corrosion is the scourge in our metal-based civilization. Corrosion-induced material degradation annually accounts for at least 2–3% of gross national product for an industrialized economy 1.
Mar 21, 2024 · Methane fermentation, utilizing food waste (FW), is viewed as a sustainable strategy that leverages garbage and agricultural waste to conserve the environment. However, FW compost encounters growth inhibition issues, which we examine in this study. The aim of this study was to assess the influence of various compost mixtures on seed germination growth and the yield of Komatsuna (Brassica rapa
Nov 29, 2013 · Sustainable Organic Integrated Livelihoods (SOIL) is a non-profit organization “dedicated to protecting soil resources, empowering communities and transforming wastes into resources in Haiti.”. Co-founded in 2006 by Dr. Sasha Kramer and Baudeler Magloire, SOIL accomplishes this by utilizing EcoSan or Ecological Sanitation, a “low cost
Jan 9, 2022 · Composting is a self-heating biological process, and the heat is a product of aerobic microbial degradation of organic matter. The produced heat influences moisture and microbial community structure [ 37 ]. High temperatures have been shown to dry out the compost and inhibit the composting process.
2 days ago · Once they’re converted into compost, organic wastes—which are the compostable portions of the solid waste stream—can be used to mulch landscaping, enhance crop growth, enrich topsoil, and provide other benefits.
Aug 25, 2021 · However, the removal of antibiotics and antibiotic resistance genes (ARGs) in the process of co-composting of food waste with sewage sludge has been rarely reported to date. Therefore, we investigated a laboratory-scale composting using food waste and sewage sludge as substrates to study changes in antibiotics and ARGs during composting.
The reuse of food waste compost and digestate as novel fertilizers contributes to a circular economy. However, food waste is a critical reservoir of antibiotic resistance genes (ARGs), and its application may lead to the spread of ARGs to vegetables, posing risks to human health.
Jan 10, 2024 · There is escalating interest in composting of post-consumption food waste (PCFW) to recycle nutrients and mitigate pollution by inappropriate disposal. The present study aimed to evaluate the performance of bioaugmentation to composting of PCFW, which is in difficulties caused by high sugar, protein and gross lipid content.
Dec 7, 2023 · 2022/11/21/ · In order to improve the cathodic protection and wear resistance of cold spraying Zn-based coatings, Zn–Ni/Cu–Al2O3 composite coating was prepared by co-depositing Zn powders, nickel-coated Cu powders, and Al2O3 powders on the steel substrate using the low-pressure cold spraying method.
The enrichment of some oil-degrading salt-tolerant microbes (Bacillus, Haloplasma, etc.) enhanced nutrient conversion, which is crucial for the improved maturity of the YM1 compost. This study demonstrated that YM1 could regulate both abiotic and biotic processes to improve high-salt and oily food waste composting, which may be an effective
Apr 1, 2022 · Analytical results from two pilot-scale composting treatments with (C20) or without (C0) mature compost demonstrated that mature compost amendment increased the reduction rate of volatile solids by 71.4% and shortened the composting period by 7 days.
