“…Meanwhile, home composting presents some potential environmental benefits such as the avoidance of collection, transportation and management of biowaste [42][43][44]. However, home composting also brings some environmental concerns: generation of GHG emissions and odor due to the absence of gas treatment systems [45,46], insufficient elimination of pathogens due to the lack of adequate heating [47] and uncontrolled leachate [48]. In fact, the GHG emissions from six home composting units were quantified as 0.4-4.2 kg CH 4 and 0.30-0.55 kg N 2 O/Mg wet organic household waste, while total GHG emissions (in kg CO 2 eq/Mg wet organic household waste) from home composting of OHW were found to be in the same order of magnitude as for centralized composting plants [49].…”

Decentralized Community Composting: Past, Present and Future Aspects of Italy

Italy is among the top biowaste-generating countries in Europe, and has a well-structured waste management framework with quite a number of centralized composting facilities. In recent years, there has also been huge interest from local communities in decentralized composting. Although decentralized community composting is common in some countries, there is still a lack of information on the operative environment together with its potential logistical, environmental, economic, and social impacts. Considering the national Italian legislation on community composting as well as successfully implemented projects at EU level, Italy can set a model especially for Mediterranean countries that intend to build decentralized composting programs. Therefore, in the context of this review paper, a brief overview of the composting process was presented together with main applications in centralized and especially in decentralized composting, while the main focus was kept on the operative and legislative information gathered from Italian community composting. There is a huge difference in the number of composting plants between the regions, and the lack of centralized facilities in the central and southern regions can be supported by decentralized solutions. Decentralizing waste treatment facilities and thus creating local solutions to urban waste management strategies will help to achieve the resource recovery and valorization targets in line with the circular economy.

“…La temperatura es el factor primordial para indicar el desarrollo del proceso de descomposición de la materia orgánica, pues este incremento en la temperatura facilita acelerar la descomposición y eliminar o reducir las poblaciones de los microorganismos existentes (Acosta et al, 2018;Arnawa et al, 2018;Chaniago y Ramlan, 2017;Fan et al, 2018). Como parámetro de control del proceso de compostaje, la temperatura debería oscilar entre 55 -65°C cuando el proceso es termofílico.…”

“…Nevertheless, the pH in the compost from the two treatments turned from acidic to weakly alkaline. This could be explained both by decomposition of organic acids by microorganisms as well as by the release of ammonia from mineralization of organic nitrogen (Fan et al 2017).…”

Composting technology comprising hyperthermophilic pretreatment (at ≥85 °C for 2 to 4 h, HTPRT) and aerobic composting was adopted to accelerate organic matter transformation and enhance nitrogen retention in chicken manure composting. The differences in physio-chemical parameters, successions, and metabolism functions of the bacterial community between HTPRT (85 °C, 4 h) and conventional composting (CK) were compared. The HTPRT composting system reached maturity 18 days in advance of CK. The HTPRT piles showed a lower maximum N loss (27.1% vs. 39.0%). The bacterial structure in the HTPRT system differed remarkably from that in CK. Ureibacillus (22.7%) and Ammoniibacillus (14.1%) were the most predominant species in the thermophilic phase of HTPRT pile, while the curing phase was dominated by Thermobifida (12.8%) and Saccharomonospora (11.8%). The authors’ results suggest that HTPRT improved the physical properties of the feedstock by reducing the bulk density, which favored microbiological activity, and thus improving composting efficiency.
