“…After 10 days of degradation, the pH had increased to 8.27, where it stabilized until the end of the degradation process. Similar behavior was reported by Valente et al (2017), when composting fish waste and Vich et al (2017) in small-scale composting of domestic waste. The increase in pH is according to Pandey et al (2016), results from the volatilization of ammonia and organic acids, the result of protein degradation during the thermophilic phase of composting.…”

“…Após 10 dias de degradação, observou-se aumento do pH até 8,27, os quais estabilizaram até o término do processo de degradação. Este comportamento também foi verificado por Valente et al (2017), em compostagem de resíduos de peixes e Vich et al (2017) em compostagem de resíduos domiciliares em pequena escala. O aumento do pH de acordo com Pandey et al (2016), ocorre devido à volatilização de amônia e ácidos orgânicos, simultaneamente à degradação de proteínas, durante a fase termofílica da compostagem.…”

It is estimated that 51% of Brazilian urban solid waste is composed of organic material, which has a high recyclability potential via alternative processes. One means of optimization and recycling this fraction would be the popularization of household composting and the dissemination of means of attaining it. The current study objective, therefore, was to evaluate control characters of the household organic residue composting process, test final organic compound product quality and investigate the feasibility of conducting such processes in urban dwellings. Organic residues were collected for three days, distributed over a week, in 20 residences of the urban area of Marmeleiro municipality, Paraná State, southern Brazil. A compost heap was set up with an initial mass of 137.21 kg of organic material. During the degradation process, temperature, dry mass, volume, pH, electrical conductivity, phytotoxicity, volatile solids, total organic carbon exothermic accumulation, and loss of organic matter were measured. At the end of the process, the CTC, CTC:COT, total nitrogen and C:N ratio were also determined. Throughout the composting process it was recorded that the germination index went from 45.27 to 109.43, as the material changed from being dominated by phytotoxic compounds to phytostimulants. In addition, organic compound CTC increased from 27.2 to 57.8, showing organic material degradation occurred in only 37 days. The experimental analysis of the degradation process, has shown that treatment of urban organic waste in compost heaps is both viable and safe under domestic circumstances.

“…Um composto bem elaborado apresenta matéria orgânica transformada em húmus e atua no solo, melhorando sua estrutura e dando-lhe condições de armazenar maior quantidade de água, de ar e de nutrientes minerais, que alimentarão as plantas (Sediyama et al, 2014). Para ser comercializado como fertilizante orgânico precisa ainda seguir as normas da Instrução Normativa nº 25/2009 do Ministério da Agricultura e Pecuária, isto é, deve apresentar as seguintes composições: umidade (≤ 50%), pH (≥ 6,0), matéria orgânica total (≥ 40%), carbono orgânico total (≥ 15%), nitrogênio total (≥ 0,5%), relação carbono/nitrogênio (≤ 20) (Valente et al, 2017).…”

O estudo avaliou a composição química do composto orgânico oriundo de resíduos de pirarucu (Arapaima gigas) e gliricídia (Gliricidia sepium). O delineamento experimental foi o inteiramente casualizado, constituído por três tratamentos (pirarucu; gliricídia; pirarucu mais gliricídia) com quatro repetições. Todas as compostagens atingiram temperatura de estabilização aos 90 dias. Os maiores níveis de fósforo, cálcio (90 dias) e zinco (90 e 135 dias) foram encontrados no composto com resíduos de pirarucu, enquanto o manganês foi maior no composto com gliricídia aos 135 dias. Para o composto com resíduos de pirarucu e gliricídia foram registrados maiores níveis de potássio, zinco (90 dias) e magnésio (105 dias). Deste modo, recomenda-se o período de 90 dias como ideal para manter a maioria dos nutrientes, pois com o aumento do tempo ocorre a redução deles, com exceção de alguns micronutrientes.

“…The fish waste term (FW) involves various elements, including whole fish, as well as specific tissues, such as heads and bones (Richardsen et al, 2017). Improper methods of fish waste disposal contribute to environmental degradation due to its large quantity (Valente et al, 2017). Fish Waste is suitable for agricultural use due to the nutrient's high contents (Illera-Vives et al, 2015).…”

The fishing sector produces substantial waste. The primary goal of this work was to obtain organic fertilizers for use in agriculture by composting fish waste. Four waste mixtures were used in the experiment: cow waste only (C), cow waste combined with dried fish waste previously collected (CF) with a mixing ratio of 1:3, poultry waste (P), and poultry waste combined with fish waste (PF) at the same mixing ratio. The fish waste treatments (PF2 and CF2) recorded a much lower pH than the untreated treatments with fish waste. The pH values were neutral values after the maturity of fish waste. The highest N percentage was in poultry with fish, followed by cows mixed with fish, poultry, and cows. Over time, the GI increased in all treatments because of the compost maturity, recording values higher than 75%. The results confirmed the compost suitability in all treatments for agricultural use. R 2 values reflect their efficiency in interpreting and predicting the results of GI based on pH, EC, and N. The results showed that the compost physicochemical properties had significant influences on the GI values. The results proved that it is possible to use fish waste mixed with of poultry and cow manure to produce an environmentally safe fertilizer and better than the compost product of poultry and cow manure only
