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
For example, Thakali et al (2022) measured up to 7.6 ng/g PFAS in food waste sampled from waste receptacles, likely co-disposed with FCMs. PFAS may also enter the compost from residual contamination of the bins re-used to transport food waste to the facility, water added during composting, or tarps used to cover curing mature compost.
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 [ Citation 37 ]. High temperatures have been shown to dry out the compost and inhibit the composting process.
Antibiotic resistance genes (ARGs) fate in a full-scale Food waste (FW) facility was investigated. Results showed that with the changes in ARGs, microbial networks could be naturally divided into two clusters, named as the ARGs increasing group (AI group) and the ARGs decreasing group (AD group).
The raw materials of composting were food waste, rape straw and sawdust. The food waste was collected from the dining hall of China Agricultural University. The rape straw and sawdust were collected from a greenhouse in Beijing, China, which were air dried and cut into 2–3 cm to enable good mixing of raw materials prior to the composting process.
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 effects of microbial inoculants on ARG removal in composting are poorly understood. Here, a co-composting method for food waste and sawdust amended with different microbial agents (MAs) was designed. The results show that the compost without MA unexpectedly achieved the best ARG removal. The add
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.
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
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.
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
The findings demonstrate that batch-feeding helped maintain high temperatures in the compost pile for an extended period (above 50 °C for 18 days), which in turn facilitated water dissi Batch-fed composting of food waste: Microbial diversity characterization and removal of antibiotic resistance genes
Nov 1, 2021 · @article{Li2021ShorttermBA, title={Short-term biodrying achieves compost maturity and significantly reduces antibiotic resistance genes during semi-continuous food waste composting inoculated with mature compost.}, author={Xunan Li and Panliang Wang and Siqin Chu and Yulu Xu and Yinglong Su and Dong Wu and Bing Xie}, journal={Journal of
