Effect of aeration rate, aeration pattern, and turning frequency on maturity and gaseous emissions during kitchen waste composting

Environmental Technology & Innovation, Год журнала: 2023, Номер 29, С. 102997 - 102997

Опубликована: Янв. 5, 2023

Currently, the increasing output of kitchen waste makes its treatment an urgent problem to be solved. Based on principle resource utilization, we consider improving various process parameters, including aeration rate, mode and turning frequency, analyzing physicochemical indicators, maturity indicators gas emissions, propose comprehensive parameters that can quickly compost, promote reduce emissions. The results showed high rate (> 0.3 L kg −1 DM min −1) reduced temperature matrix increased electrical conductivity germination index thereby inducing strong emissions odors greenhouse gases. Compared with continuous aeration, intermittent was more effective in reducing gaseous under same total volume but characterized by lower maturity. Moreover, it found non-turning substantially, while excessively (once every 2 days) or too low 6 frequency varying degrees. Most frequencies did not significantly compost above indicated rapid composting processes yielded best were 0.2∼0.3 −1, pattern, a once three days. This research great significance improvement combined process.

Synergistic bioconversion of organic waste by black soldier fly (Hermetia illucens) larvae and thermophilic cellulose-degrading bacteria

Frontiers in Microbiology, Год журнала: 2024, Номер 14

Опубликована: Янв. 10, 2024

Introduction This study examines the optimum conversion of Wuzhishan pig manure by Black Soldier Fly Larvae (BSFL) at various phases development, as well impact gut microbiota on efficiency. Method and results In terms efficiency, BSFL outperformed growing stage (GP) group, with significantly higher survival rates (96.75%), fresh weight (0.23 g), larval rate (19.96%) compared to other groups. Notably, GP group showed significant dry matter reductions (43.27%) improved feed (2.17). Nutritional composition varied, having a lower organic carbon content. High throughput 16S rRNA sequencing revealed unique profiles, exhibiting an excess Lactobacillus Clostridium . Promising cellulose-degrading bacteria in intestines, including Bacillus cereus subtilis , superior cellulose degradation capabilities. The synergy these thermophilic greatly increased BSFL1-10 demonstrated high growth efficiency under specific conditions, remarkable moisture content (71.11%), residual (63.20%), waste reduction (42.28%). Discussion sheds light optimal stages for manure, dynamics, promising bacteria, enhancement through synergistic interactions. These findings hold great potential sustainable management efficient biomass conversion, contributing environmental preservation resource recovery.

Measures for Controlling Gaseous Emissions during Composting: A Review

International Journal of Environmental Research and Public Health, Год журнала: 2023, Номер 20(4), С. 3587 - 3587

Опубликована: Фев. 17, 2023

Composting is a promising technology for treating organic solid waste. However, greenhouse gases (methane and nitrous oxide) odor emissions (ammonia, hydrogen sulfide, etc.) during composting are practically unavoidable, leading to severe environmental problems poor final compost products. The optimization of conditions the application additives have been considered mitigate these problems, but comprehensive analysis influence methods on gaseous lacking. Thus, this review summarizes different emissions, cost each measure approximately evaluated. Aerobic can be achieved by appropriate process conditions, so contents CH4 N2O subsequently effectively reduced. Physical effective regulators control anaerobic having large specific surface area great adsorption performance. Chemical significantly reduce their side effects must eliminated. auxiliary effect microbial agents not absolute, closely related dosage compost. Compound more efficiently than single additives. further study required assess economic viability promote large-scale utilization composting.
