Abstract:

This study conducted a systematic literature review and content analysis to examine the state of the art in organic waste composting through commercial adoption for the circular economy (CE) and reduced environmental consequences in advancing sustainable waste management within a CE framework. Commercial composting diverts substantial amounts of organic waste from landfills, reducing methane emissions. For instance, the Japanese food processing industry generates 9.5 million tons of organic waste annually, with 25% directed to composting, highlighting its role in waste reduction. This research

Abstract Compost is a solid organic material that biologically changes into a final product that can be used as fertilizer. Utilizing shallot leaf waste as raw material for composting is the latest technology and has never been applied by shallot farmers.

During the past decade, numerous commercial composting systems have been developed. Time, as well as economics, are determining which of these systems are feasible. Systems that take time but can operate at low cost are surviving, as are more costly systems capable of producing a mature compost in the shortest possible time. Which system to use can be determined by the amount of space available and the amount of feedstock to be composted. Where space is limited and the volume of feedstock is high, more intensively managed systems are necessary. When space is not a limiting factor, more passive

Five containers were employed for investigating the effects of five doses of CaO2 (0%, 5%, 10%, 15%, and 20%, w/w) on physicochemical parameters, organic matter (OM) degradation, and humification during composting. Additionally, more evidence from a microbial perspective was prov

Abstract:

Composting is widely used to recycle a variety of different organic wastes. In this study, dairy manure, chicken litter, biosolids, yard trimmings and food waste were selected as representative municipal and agricultural feedstocks and composted in simulated thermophilic composting reactors to compare and evaluate the GHG emissions. The results showed that the highest cumulative emissions of CO2, CH4 and N2O were observed during yard trimmings composting (659.14 g CO2 kg−1 DM), food waste composting (3308.85 mg CH4 kg−1 DM) and chicken litter composting (1203.92 mg N2O kg−1 DM), respectively.

We measured nitrogen components during composting process of feces in a batch test in which sawdust was used as a matrix. Further decomposition rates of fecal nitrogen and carbon were obtained in the batch tests of different feces loading. In composting material that was a mixture of sawdust and fresh feces, fecal organic matter decomposed to CO2 and fecal nitrogen mineralized to ammonia during the composting process. The biological response of organic matter and nitrogen in the composting material was evaluated by oxygen consumption (OUR) and ammonia production that was a sum of volatilized a

AbstractWith the growing concern about the impact of agriculture on water quality and heightened interest in managing agricultural by-products economically, the use of composting by U.S. farmers is increasing. Over 8,000 farms are now composting animal mortalities, manure, crop residues, and selected organic materials from communities and industries. At least 75% of farm composting operations are composting poultry mortalities. Based on discussions with contacts in leading agricultural states and organizations, this paper provides examples of technical and economic incentive programs encouragi

Microorganisms are of critical importance during the composting process. The aim of this study was to reveal the bacterial and fungal compositions of a composting pile of food waste digestate and garden waste, where the succession of the microbial communities was monitored using Illumina MiSeq sequencing. We explored the efficiency of composting of different microorganisms to judge whether the composting system was running successfully. The results showed that the composting process significantly changed the bacterial and fungal structure. Firmicutes, Proteobacteria, and Bacteroidota were the

Abstract:

Generally, rural areas can contain large amounts of organic and household wastes, which on average, is rarely managed well. Meanwhile, composting is a waste management method that decomposes organic waste biologically, thus contributing toward better waste management and environmental sustainability. However, exposure to more efficient waste management methods and the knowledge of the importance of composting are still low among rural communities. These communities also do not realise that composting has the added potential benefit of increasing household income. Therefore, this exploratory st

Composting is an aerobic biotic decomposition route that is governed by physicochemical and microbiological factors. The importance of bacterial flora throughout composting is well recognized. Though, diversity of the bacterial population during composting may differ with the composting material and nutrients content. Therefore, it is essential to study the different types of bacteria during the composting of various agricultural byproducts. The aim of this review is to evaluate the diversity of bacteria, physicochemical factors and quality of compost for cultivation of Agaricus bisporus (whit

The composting process was comprehensively analyzed with the potential ecological risk assessment of heavy metals and redundancy analysis. The addition of 10.0% biochar during composting had a strong passivation effect on exchangeable Cu and Cd, with passivation rates of 11.75 and 63.89%, respectively; the addition of 2.5 and 7.5% biochar

Abstract Georgia, as a developing country, faces challenges of biodegradable waste management. The promotion of the modern composting systems is the major problem for the country, given that the generation of municipal waste is characterized by increasing dynamics and, therefore, the amount of biodegradable waste is also increasing every year. By 2030, waste generation is expected to increase maximum to 1.2 % annually, which should be the cause of significant challenges for local municipalities whose duties include municipal waste management, including recycling/composting activities.

Abstract:

The composting of green waste (GW) proceeds slowly due to the presence of slowly degradable compounds in that substrate. The introduction of amendments and bulking materials can improve organic matter degradation and end-product quality. However, additional strategies such as two-stage composting, can deal with the slow degradation of green waste. This paper evaluates the effect of two-stage composting on the process and end-product quality of the co-composting of green waste and food waste amended with sawdust and phosphate rock. A pilot-scale study was developed using two treatments (in trip
