| Different fractions of banana (stalk, peel, and flesh) as well as the whole unpeeled banana were studied in a laboratory Biochemical Methane Potential (BMP) assay. After completion of 35-day digestion at 37°C in 2L-reactors, specific methane yields reached 0.256, 0.322, 0.367 and 0.349 m³/kg VS (volatile solids) for stalk, peel, flesh, and unpeeled banana respectively. Considering the country of Uganda, East Africa, the collection of peels and stalks from banana production would yield a theoretical potential of about 60 GWh of electrical energy per year in biogas plants. In order to verify the suitability of banana fractions to the biogas process, their chemical composition was analyzed, and their methane production kinetics was estimated with exponential... |

| Abstract: The volume of global gross banana exports reached a record of 117.9 million tonnes in 2015 (FAO 2017), which agro-industrial wastes derived as the pseudo-stem, rachis and leaves do not have an industrial application instead they are discarded. This research study applies full factorial design and response surface methodology to determine the effect of pressing temperature and resin content on density (D), moisture (M), water absorption (WA), water swelling (WS), module of rupture (MOR), module of elasticity (MOE) and formaldehyde content (FC) of particle board made of banana pseudo-stem. A 22 factorial design was performed, factors considered were resin and temperature. The low level of resin was 15% in the coarse fiber (CF) and 35% in fine fiber... |

| Fifty-seven by-products were collected from regions throughout Brazil. Chemical composition, in vitro neutral detergent fiber digestibility (IVNDFD), and total digestible nutrients (TDN) were determined with the objective of grouping by-products with similar nutritional characteristics. The by-products belonging to group one (G1) presented the highest content of neutral detergent fiber exclusive of ash and nitrogenous compounds [aNDFom(n)] and lowest energy content, with 42.5% and 38.8% of IVNDFD and TDN, respectively. A new cluster analysis was carried in order to better characterize G2 by-products, six subgroups (SGs) were established (SG1 to SG6). SG1 by-products had the highest and the lowest values for lignin and TDN, respectively. SG2 by-products had... |

| ABSTRACT The objective of this study was to evaluate sugarcane straw decomposition and the potential of increasing soil carbon as a function of the initial biomass and vinasse addition to soil surface. The experimente consisted of incubation (240 days, in the dark, humidity equivalent to 70% of soil water retention capacity and average temperature of 28 °C) of Oxisol soil samples (0-20 cm soil layer) with straw added to soil surface at rates of 2; 4; 8; 16 and 24 t∙ha−1 and with or without vinasse addition (200 m3∙ha-1). The following variables were determined: released C-CO2, remaining straw dry matter, carbon straw and soil carbon concentration. The added biomass did not influence straw decomposition rate, but vinasse treatments provided rates between 70... |

| Abstract The passion fruit peel flour, retrieved from the drying and milling of fruit-processing residues, is rich in fibers. In fact, it is an important food source, featuring many benefits for the human organism. Current study forwards a scientific and technological evaluation of the passion fruit peel flour development through bibliometric indicators. Data from scientific production were collected from Web of Science database and patent search was performed at different databases USPTO, WIPO, EPO and INPI. Bibliometric analysis addresses key sections focused on articles and patent applications, authors and inventors, relevant areas of interest, institutions and countries. The analysis of citations and analysis of social networks were also used as... |

| Con el objetivo de evaluar el efecto de dos abonos líquidos fermentados elaborados de subproductos regionales, en la producción de plántulas de chile habanero (Capsicum chinense Jacq), en la fase de vivero; se estableció el experimento en un predio del poblado C-34, Plan Chontalpa, Huimanguillo, Tabasco. Para la obtención de los abonos líquidos fermentados se utilizó el biodigestor tipo estacionario o Batch, a los cuales se les hizo las adecuaciones en la tapa que funcionó como válvula de escape, para la liberación de los gases generados durante la fermentación. Se utilizaron dos abonos, uno con biomasa de estiércol fresco de bovino (Biol Eb) y otro con follaje fresco de Gliricidia sepium (Jacq) (Biol Gs). Se realizaron tres repeticiones para determinar el... |

| ABSTRACT Although difficult to pin down an exact figure, the idea that postharvest losses (PHL) of perishables in Brazil stand at 30-45% has been widely accepted. In spite of the modernization of production systems and the logistics and distribution of perishables in the last decades, postharvest losses continue to be a persistent and relevant problem. However, little is known about what has already been published on the subject. This work addresses precisely this issue, based on a comprehensive survey of publications on PHL of fruits and vegetables. Bibliographic searches were performed at the Embrapa’s library system, Google Scholar and SciELO. Several publications on PHL of fruits and vegetables were reviewed and grouped according to their scope and... |

| A compostagem se enquadra no processo biológico de reciclagem de nutrientes e surge como uma alternativa viável por reduzir o peso e o volume dos resíduos gerados. A compostagem é uma técnica de decomposição e sanitização da matéria orgânica à alta temperatura, pela ação de bactérias e fungos que transformam as carcaças em um produto útil, denominado de composto orgânico. Essa técnica é acessível ao produtor rural e as agroindústrias, tais como frigoríficos e abatedouros. O composto orgânico é um adubo que pode ser utilizado em áreas agrícolas, conforme Instrução Normativa nº 25 de 2009 do Ministério da Agricultura, Pecuária e Abastecimento, que trata da produção e do uso de compostos orgânicos. O uso de composto orgânico apresenta as vantagens de reduzir... |

| European water legislation enforces increasingly restrictive measures with regards to reduction of water consumption and waste emission in order to minimise the potential environmental impact of the agro industry sector. Fish farms are particularly concerned, but legislation covering effluent discharge varies significantly from country to country. However, recommendations and directives from institutional, national or regional bodies suggest the enforcement of increasingly strict waste reduction measures and the development of waste treatment. Before treatment, it is necessary to evaluate waste production in terms of composition and quantity. The waste quantification methods used today for fish culture systems are either based on direct measurements of... |

| The dual objective of sustainable aquaculture, i.e., to produce food while sustaining natural resources is achieved only when production systems with a minimum ecological impact are used. Recirculating aquaculture systems (RASs) provide opportunities to reduce water usage and to improve waste management and nutrient recycling. RAS makes intensive fish production compatible with environmental sustainability. This review aims to summarize the most recent developments within RAS that have contributed to the environmental sustainability of the European aquaculture sector. The review first shows the ongoing expansion of RAS production by species and country in Europe. Life cycle analysis showed that feed, fish production and waste and energy are the principal... |
