| ABSTRACT By 2017, Brazil seems to have finally awakened to the problem of food loss and waste. In this article, we resume the topic started in the article “Postharvest losses of perishables in Brazil: what do we know so far?” published earlier this year, but now with an emphasis on food losses and waste (FLW). We divided this article into four sections: (a) search for scientific publications on postharvest losses (PHL) and food waste (FW) in Portuguese; (b) social classes and food consumption in Brazil and household food waste; (c) the national legal framework on FLW; and (d) current food security policies and civil society actions on FLW. Google Scholar searches yielded 46,100 records for FW and 16,100 for PHL, but only 37 and 19 records, respectively,... |

| ABSTRACT This study was designed to assess the effects of feeding space availability on social behavior and performance of housed crossbreed sheep through the use of three different types of feeders. Thirty-six crossbreed ewes (Santa Inês × Dorper; 2-3 years old) with initial body weight of 34.99±4.28 kg were randomly assigned to a 3 × 3 (feeder type × available space at the feeder) factorial arrangement among nine pens. Pens had one of three feeder types (concrete bunk, plastic, or wood barrel) and one of three amounts of available space in the feeder (0.33, 0.25, or 0.20 m animal−1). Total dry matter intake/pen, dry matter intake per animal, total weight gain/pen, daily weight gain/animal, and food waste were evaluated. Percentage of time spent at... |

| The biogas unit under investigation is a specially designed portable assembly biogas unit and is sought to be widespread and commonly used in Egypt by the Egyptian Environmental Affairs Agency (EEAA). This unit is able to anaerobically treat different types of organic wastes, which are: food waste, kitchen waste, and waste from landscape. The main objective of this study is to perform an environmental impact evaluation of the implementation of this biogas unit. The specific greenhouse gas (GHG) emissions of using the produced biogas from the unit for electricity and heat generation were calculated, where the methodology of life cycle assessment (LCA) was applied. The results show the GHG emissions for each component of the biogas unit and each process... |

| The enzymatic hydrolysis of food waste by commercially available enzymes and the subsequent ethanol fermentation of the hydrolysates by Saccharomyces cerecisiae H058 were studied in this work. The optimum batch enzymatic conditions were found to be saccharification pH of 4.5, temperature of 55!, glucoamylase concentration of 120 u/g, α-amylase concentration of 10 u/g, solid-liquid ratio of 1: 0.75 (w/w). Fed batch hydrolysis process was started with a solid-liquid ratio of 1: 1 (w/w), with solid food waste added at time lapse of 2 h to get a final solid-liquid ratio of 1: 0.5 (w/w). After 4 h of reaction, the reducing sugar concentration reached 194.43 g/L with a enzymatic digestibility of 93.12%. Further fermentation of the batch and fed batch enzymatic... |
