Currently, insects have been used as allies of circular economy.These organisms present desirable features and can help humans with some society problems, like organic waste management, sustainable livestock feeding fuel production, well fertilizer.Among many invertebrates, one mention the black soldier fly (BSF), Hermetia illucens (Diptera: Stratiomyidae).A species spread worldwide, whose larvae convert, in 14 days on average, streams into frass (larval humus).Besides importance weight/volume reduction, these products considered an alternative protein oil ingredients for animal feed, being plant fertilization high lipid content biodiesel production.In this work, effects different larval densities BSF were verified conversion four wastes experimental units 7kg substrate per batch: cow, sheep laying hen manure, pizza restaurant (leftover border).In overall, higher produced smaller larvae, egg-larvae viability content, weight reduction rates.The affected cow lower populations.Larval period was not by density means 13.5, 12 18 days, respectively.Larval pizza's varied between 12.8 14.8 increased time densities.The crude (CP) (LC) dry matter basis manure 44.43% 35.5-16.8%,respectively.Larvae from presented CP 44.4-40% LC 14-3.56%Fromhen 34.63% about 15.3-2.05%.Larvae ca.34.64% 49.42%.Frass NPK levels only K macronutrient manure.In others, elements observed above minimum legislation required Brazil Ministry Agriculture.Therefore, most production biological parameters than final product composition parameters.It possible to observe behavior at population wastes.Valuable information generated planning bioconversion systems BSF, they be applied management feed alternate fertilizers, promoting economy.
