It is also important to mention that during the anaerobic digestion process, there is a change of the N organic form into ammonium (NH 4 ), representing more than 60% of the TNK according to Costa et al (2016a), and this is one of the forms in which plants can use this nutrient, so this process contributes to the improvement of the agronomic value of wastewaters.…”

A B S T R A C TAiming to evaluate different wastewaters in the anaerobic co-digestion (ACoD) of hatchery wastes, a batch test was conducted in bench horizontal digesters. At the end of the process, the potential production of biogas and methane was calculated as well as the chemical composition (macro-and micronutrients) of the effluent and the concentrations of methane and carbon dioxide gas at 60 days. The monitoring of the process included observations of the reduction of the organic carbon, chemical oxygen demand, and total (TS) and volatile solids (VS), as well as the variation of pH and electrical conductivity (EC). The results showed that the mixing between the hatchery fresh waste and swine wastewater (T 4 ) and among fresh hatchery waste, water from the first anaerobic pond of the hatchery and swine wastewater (T 5 ) represent significant sources of renewable energy and thereby greater potential for biogas production (192.50 and 205.0 L biogas per kg of VS added to T 4 and T 5 , respectively). The average concentration of methane in the biogas varied from 72 to 77% among the treatments. For all treatments, reductions were observed in TS and VS and increases in pH and EC. It was concluded that the energy recovery from hatchery wastes is favoured by the addition of swine wastewater in the ACoD process.Co-digestão anaeróbia de resíduos de incubatório e águas residuárias para produção de energia e biofertilizante -Fase batelada R E S U M O Visando avaliar diferentes águas residuárias na co-digestão anaeróbia de resíduos de incubatório foi realizado ensaio batelada conduzido em biodigestores horizontais de bancada. Ao final do processo foram determinados a produção e os potenciais de produção de biogás e de metano bem como a composição química (macro e micronutrientes) do efluente e a concentração de metano e gás carbônico aos 60 dias. O monitoramento do processo foi acompanhado pela redução de carbono orgânico, demanda química de oxigênio, sólidos totais e voláteis (ST e SV), além da variação do pH e da condutividade elétrica (CE). Os resultados obtidos revelaram que as misturas entre resíduo fresco de incubatório e água residuária de suinocultura -ARS (T 4 ) e resíduo fresco de incubatório + água da primeira lagoa anaeróbia do incubatório + ARS (T 5 ) apresentaram os melhores potenciais de produção de biogás (192,50 e 205,0 L biogás por kg de SV adicionados, respectivamente). Aos 60 dias a concentração média de metano variou de 72 a 77% entre os tratamentos. Para todas as situações avaliadas observou-se redução de ST e SV e aumento do pH e da CE. Concluiu-se que a recuperação de energia dos resíduos de incubatório é favorecida pela adição de ARS em co-digestão anaeróbia.

In China, chestnut burrs (CB) are produced at a rate of a million tons per year as the major byproduct of chestnut orchards. It is necessary to utilize the chestnut forest green waste and convert it into a valuable seedling media for the sustainable cultivation of chestnut seedlings. In this study, we composted CB with two waste products of cattle farming, namely cow manure (CM) and bovine bone (BM). We also evaluated the potential of CB compost application in chestnut forest sustainability. Results indicated that the best combination was the addition of 15% BM and 55% CM. This combination significantly improved the composting environment by increasing pH, enhancing phosphorus concentration and mineral elements such as Ca, Na, Mg and Zn, and shortened the composting period to 38 days. This combination also resulted in the highest content of citric acid-P (109.20 times than the control treatment) and the lowest content of NH 4 + -N (0.28 times than control treatment) indicating a better N and P structure of the final compost product. This combination achieved a greater degradation rate of CB cellulose (61.45%), hemicellulose (37.87%), and a more significant degradation of outer epidermis structure. When CB compost was used as a growing media, a significant decrease in photosynthesis stress of chestnut seedlings was observed, which was mainly manifested as a decrease in photochemical quenching (qP) and an increase of the maximum efficiency of PSII photochemistry under dark-adaption (Fv/Fm). Addition of 10% CB compost (in volume basis) is suggested, which resulted in the tallest chestnut seedlings (59.83 cm) with a stem diameter of 0.91 cm after six months of growth. In summary, this research provides an environmentally friendly strategy for chestnut orchard sustainability: rapid composting of CB, then immediate application as a high-quality substrate for chestnut seedlings.Agronomy 2020, 10, 288 2 of 18 step for chestnut production. The popularization of burr removal equipment has resulted in the need for intensive management of CB. Due to CB recalcitrant biodegradability and knotty spicular structure, incineration is still the main method of dealing with CB waste [3,4]. Since CB, as FGW, is rich in organic matter and minerals, it is desirable to convert it into a high value byproduct such as compost.Composting is a popular and clean method to dispose of FGW [5]. Mature FGW compost has high porosity and high organic carbon content and can be utilized as a high-quality soil amendment [6]. Shrestha et al. [7] reported that the application of compost increased soil organic carbon content, reduced CO 2 and N 2 O emissions, and increased CH 4 uptake. Chehab et al. [8] indicated that the olive FGW compost amendment resulted in an increased performance in mature olive trees and in a maximum yield of photosystem II (Fv/Fm). Composting recycles organic matter, nitrogen, phosphorous, and mineral elements in the FGW when growing seedlings [9]. In a recent study, Shalizi et al. [10] increased the biomass of Eucalyptus bentham...

“…In an inventory of organic waste for use as substrates performed by Abad et al (2001), it was found that almost half (46%) of the 63 organic materials studied presented suboptimal OM levels. OM levels below the recommended value (>80%) in composted substrates are expected, due to the microbiological degradation of organic fractions and consequent release of C as CO2 (Costa et al, 2016(Costa et al, , 2017Lorin et al, 2016). As a result, a concentration of macro and micronutrients can be observed (Costa et al,2017;Gavilanes-Terán et al, 2017) (Table 3).…”

Addition of Boiler Charcoal Waste to Compost for Use as Substrate for Vegetable Seedlings

The recovery of waste from the broiler production chain (BPC) is consistent with the principles of a circular economy. Besides turning waste into organic compost, its use as substrate for the production of vegetable seedlings further increases its economic value. However, it is necessary to adapt its characteristics to enable its use as substrate. To this end, the addition of boiler remnant charcoal wastes (BCW), another type of waste generated in the BPC, to the organic compost resulting from the composting of BPC waste with different bulking agents (BAs) was studied. The addition of BCW to agro-industrial compost reduced the electrical conductivity (EC) of substrates. Multiple linear regression showed that, of the 13 variables (physical, chemical and physicochemical) studied, three (EC, pH and N content) are sufficient to explain the seedling quality index (SQI). Simple nonlinear regression showed that, in order to achieve higher SQIs and easier removal of clod from tray, an additional 30% in weight of BCW is required for compost, using urban tree pruning, wood sawdust and sugarcane bagasse BAs. The use of cotton and Napier grass waste as BAs is not recommended for BPC waste mixtures, as they cause a large increase in substrate EC.
