Anthropic methane emissions can largely be prevented or minimized using technologies that are already available. One such technology is anaerobic digestion (AD), which is used commercially around the world, especially in Europe and the United States, where some challenging targets have been set to diversify the energy mix with more renewable energy. This foresight study was designed to identify...

anaerobic digestion of organic solid waste (osw) from kitchen was conducted in completely stirred tank reactors (cstrs) under both mesophilic and thermophilic conditions. the lab-scale reactors were fed with the osw containing 10% of total solids (ts) at a hydraulic retention time (hrt) of 30 days (3.0-3.5 g-ts/l/d of volumetric loading rate). both mesophilic and thermophilic reactors exhibited...

anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.this technology is superior to the landfilling and also the aerobic composting. the aim of the present study was to examine whether the effluent volatile fatty acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...

Valorisation of organic wastes in renewable energy production has attracted a global attention order to achieve sustainable industrial growth. Anaerobic digestion (AD) is considered be one the most environmentally friendly waste management technology and also fulfils necessity fuel generation. It much less demand than other technologies like gasification or pyrolysis due its low operation tempe...

Biogas production involves various types of intricate microbial populations in an anaerobic digester (AD). To understand the digestion system better, a broad-based study must be conducted on population. Deep understanding complete metagenomics including structure, functional gene form, similarity/differences, and relationships between metabolic pathways product formation, could aid optimization...

The transition to a circular economy relies on systems that facilitate waste recovery and recirculation of resources. These are based certain enabling technologies. aim this paper is explain how socio-economic structures influence the diffusion such It applies framework built societal embedding varieties capitalism compare anaerobic digestion (AD) in Sweden northern Europe Paraná southern Brazi...

Sustainable development closely links to the context of energy. Replacing fossil fuels with sustainably produced biomass or organic residues will not only be a way to cope with the depletion of fossil fuel resources but also to reduce the CO2 emissions into the atmosphere and therefore minimise the risk of global warming. A large variety of methods of biomass energy conversion are available tod...

Anaerobic digestion is a well-established biological process for converting biomass in waste streams into a renewable energy source, and it also contributes to the treatment of these waste streams. In this introductory mini-review, some fundamental aspects of anaerobic digestion for use in the pulp and paper industry and other sectors are briefly summarized. The contents include the basics of a...

Small-scale anaerobic digestion (AD) can be an effective organic waste management system that also provides energy for small businesses and rural communities. This study measured fuel production from digestions of single mixed feedstocks using unheated, 2 m3 digester operated continuously in a temperate climate over three years. Using local food waste, brewery grease agricultural residues, this...

Anaerobic digestion (AD) of ammonia-rich swine manure (SM) with nano-bubble water (NBW) supplementation was studied in this work the expectation ammonia inhibition alleviation, buffering capacity promotion, and methane production enhancement. Results indicated that cumulative yield elevated by 12.3–38.7% NBW groups. Besides, reduced rate elongated lag phase under were increased shortened supple...
