“…Feathers can be utilized for energy production by eliminating harmful environmental and catastrophic issues. In this way, on one hand, waste is properly managed, and, on the other hand, bioenergy in the form of biogas is produced ( Provin et al, 2021 ) from the waste. Therefore, the current study was designed to evaluate the effect of different pretreatments and co-digestion and mono-digestion by AD using batch and continuous fermentation and its effect on biogas yield.…”

To utilize wastes and residues sustainably and excellently, there is a need to fend for efficient methods and resources for biogas production. Use of poultry waste for biogas production represents one of the most important routes toward reaching global renewable energy targets. The current study involves microbial pretreatment of chicken feather waste, followed by its co-digestion with rice husk and green grocery waste in batch and continuous reactors, respectively. Microbial pretreatment of chicken feathers by keratinase secreting Pseudomonas aeruginosa was an effective and eco-friendly approach to make its recalcitrant structure available as a raw substrate for biogas production. The current study also addressed the enhancement and stability of anaerobic digestion by co-digestion. Results demonstrated that biogas production was increased by microbial pretreatment of chicken feathers and that the percentage increase in biogas yield was 1.1% in microbialy pretreated feathers compared to mono-digestion (non-pretreated feathers) in batch fermentation. The highest yield of biogas was obtained in a batch reactor having co-digestion of pretreated rice husk and microbial pretreated chicken feathers. The co-digestion of chicken feathers hydrolysate with green grocery waste in continuous fermentation mode has also enhanced the biogas yield as compared to average of mono-digestion (chicken feather hydrolysate and green grocery waste) and, therefore, improve the efficiency of the overall process.

“…Desta forma, é possível expandir o modelo de negócio existente ou mesmo possibilitar a especialização de empresas no tratamento de subprodutos. Como exemplos, foram identificados na amostra estudos que tratavam da obtenção e tratamento da caseína e da proteína do soro do leite (COSTA et al, 2021); do uso de fibras de abacaxi resultantes da produção de suco para a confecção de roupas (PROVIN et al, 2021); do reaproveitamento de resíduos biológicos na composição de fármacos e corantes (ANCUTA; SONIA, 2020; DEL RIO OSORIO; FLÓREZ-LÓPEZ; GRANDE-TOVAR, 2021); e pelo tratamento de restos alimentares para produzir adubo orgânico e alimento para aves e peixes (NATTASSHA et al, 2020).…”

O objetivo deste artigo é identificar artigos acadêmicos que tratam da transição para a economia circular (EC) no setor alimentício e analisar os principais estímulos, barreiras e práticas envolvidas neste processo. Para isso, uma revisão sistemática de literatura foi conduzida, utilizando a base Scopus. A partir da análise bibliométrica, de rede de palavras-chave e de conteúdo, foi possível obter uma visão geral das discussões atuais sobre o tema, que apresenta um crescente interesse, com protagonismo de países europeus e do Brasil. Entre os principais estímulos, foram identificados a eficiência energética, as novas oportunidades de mercado, a colaboração com stakeholders, a ecoeficiência e as possíveis reduções de custos. Dentre as barreiras, foram cinco as principais: tecnológicas, financeiras, operacionais, aceitação dos consumidores e legislação. A redução do consumo de matéria prima e o uso de subprodutos foram as práticas mais abordadas pelos artigos, indicando que o setor alimentício ainda tem potencial para implementar outras estratégias em direção à EC, como resultado da manufatura eficiente e uso mais inteligente dos produtos.

“…This creates a domino effect where it results in a shortage of raw materials and increases in cost due to the handling and disposal of waste [28,29]. The circular economy and its acceptance have a direct effect on the fight against waste, since it uses waste as a product, contributing to the minimization of pollution [30]. To achieve positive changes with respect to the conservation of the environment, the use of innovative technologies for solid waste management must be counted on, taking the circular economy as the main focus, since it is framed around the valorisation of waste as a resource [31].…”

The enormous environmental problems that arise from organic waste have increased due to the significant population increase worldwide. Microbial fuel cells provide a novel solution for the use of waste as fuel for electricity generation. In this investigation, onion waste was used, and managed to generate maximum peaks of 4.459 ± 0.0608 mA and 0.991 ± 0.02 V of current and voltage, respectively. The conductivity values increased rapidly to 179,987 ± 2859 mS/cm, while the optimal pH in which the most significant current was generated was 6968 ± 0.286, and the ° Brix values decreased rapidly due to the degradation of organic matter. The microbial fuel cells showed a low internal resistance (154,389 ± 5228 Ω), with a power density of 595.69 ± 15.05 mW/cm2 at a current density of 6.02 A/cm2; these values are higher than those reported by other authors in the literature. The diffractogram spectra of the onion debris from FTIR show a decrease in the most intense peaks, compared to the initial ones with the final ones. It was possible to identify the species Pseudomona eruginosa, Acinetobacter bereziniae, Stenotrophomonas maltophilia, and Yarrowia lipolytica adhered to the anode electrode at the end of the monitoring using the molecular technique.
