Mar 9, 2023 · Controlled anaerobic, or oxygen-free, digestion of animal manure is a way to treat manure to prevent foul odor production while generating a usable energy product. Under the right conditions, liquid manure will break down into biogas and a low-odor effluent. Biogas can be burned to produce heat, electricity, or both the anaerobically-digested
The abundance of organic solid waste throughout the world has become a common issue that needs complete management at every level. Also, the scarcity of fuel and the competition between food and substance as an alternative to a petroleum-based product has become a major problem that needs to be properly handled. An urge to find renewable substances for sustainable development results in a
Sep 27, 2023 · Kitchen waste (KW) generates odors comprising complex volatile organic compounds (VOCs). We used gas chromatography–mass spectrometry to analyze VOCs, and 16S gene sequencing was used to analyze the microbial community composition and microbial metabolic mechanism. The results showed that the major odor-causing VOCs were hydrogen sulfide, methanethiol, methyl sulfide, dimethyl disulfide, and
Feb 1, 2023 · A key process in treating odor gases is predicting the production of odors from domestic waste. In this study, four factors of domestic waste (weight, wet composition, temperature, and fermentation time) were adopted to be the prediction indicators in the prediction for domestic waste odor gases.
Mar 26, 2021 · Food waste and byproducts are generated along the entire food processing and storage chain. The large amount of waste deriving from the whole process represents not only a great economic loss but also an important ethical and environmental issue in terms of failure to recycle potentially reusable materials. New, clear strategies are needed to limit the amount of waste produced and, at the same
Mar 26, 2021 · 2. Agri-Food Waste: A Rising Problem or a Valuable Resource? Among the different food sectors, it is estimated that fruit and vegetables represent a large part of waste production, notably in the detail that about 45% of the total produced amount is lost in the production and consumption chains, generating a great quantity of waste material [9,10].
Jan 1, 2024 · Odorous organic gas emission characteristics from cooked food wastes during aerobic decomposition. ZumingWanga, ZhishuLiangab, GuiyingLiab, TaichengAnab. Show more. Add to Mendeley. https://doi.org/10.1016/j.jclepro.2023.139961Get rights and content. Highlights. •. VOCs in air released from cooked fish were 7.7 times higher than that of cabbage. •.
Feb 15, 2024 · The solid waste produced by livestock and poultry breeding industries can substantially impact the daily production and life of people. The odor nuisance chiefly originates from the decomposition of animal feces, sewage, litter, feed, and gases discharged from the digestive tract of livestock (Mariuzza et al., 2022, Gutarowska et al., 2014).
Sep 17, 2013 · This study investigated the composition, content, and distribution of odor gases emitted from the anaerobic fermentation of food waste. The tested odor concentrations can be considered as effective standards for indicative assessment, wherein the S-compounds were the main odor gases in the workplace, with significant odor characteristics.
Feb 8, 2022 · The anaerobic fermentation of kitchen waste can produce a large amount of biogas, which is a clean renewable energy that can be used for power generation and as fuel. The fermentation residue can be used to make organic fertilizer. The fermentation system is completely closed without generating odor.
Nov 1, 2015 · This article discusses many of the problems that can arise related to large-scale industrial fermentation vessels (that is, those with a capacity up to 1 million gal) that are increasingly being used for industrial bioprocesses. It also presents recommendations for appropriate CIP and sterilization design for large-scale systems.
Pet waste disposal is a problem. Bokashi Cycle allows you to reduce the risk of contaminating groundwater, turn pet waste into something useful, and feel good about keeping this waste out of the landfill and garbage can. Cats, dogs, and other domesticated animals generate a very large amount of daily waste. Most pet owners are responsible, pick
Feb 28, 2024 · Flavour is a key driver of consumer preferences and acceptability of foods, and the food industry has made food aroma compounds a crucial area of research. At present, about 80% of food aroma compounds are produced by chemical synthesis; however, alternative production approaches have been explored to meet consumers’ demand for “clean label” food products and “natural” aromas. Bio
Nov 29, 2016 · For active odor control, it is necessary to set up a network of atomizing nozzles around the main odor-producing parts of the site, which are fed under pressure with a dilute, aqueous solution of an effective odor control chemical formulation.
Jun 6, 2024 · The highest fermentation rate of free LT yeast was similar to that reported by Lúquez-Caravaca et al. 2023 and Puig-Pujol et al. 2013 , where fermentation kinetics with free cells were faster than those with immobilized cells. As noted in these studies, this could be due to the slight stress on the immobilized cells and/or the effect of the
