Original article: fermented pulp and paper bio-sludge as feed for black soldier fly larvae

Abstract This study evaluates the use of fermentation to increase nutrient availability in pulp and paper bio-sludge (PPBS) as feed for black soldier fly larvae (BSFL). Rearing BSFL on fermented PPBS was carried out a climate chamber order assess survival growth. The used came from chemo-thermomechanical pulp/groundwood mill. at 35 °C 55 °C, respectively, initial pH 10. effects sediment liquid dry weight, rate until prepupae stage, bioconversion, reduction were measured. bioconversion liquids (4.1–6.6%) substantially higher than both sediments untreated (? 0.4%). rate, other hand, lower (26.3–30.9 %) (49.5–52.6%). Neither nor had significant weight or rate. no effect bioconversion. demonstrates that dissolves part dissolved substances readily convert biomass. However, bulk lignocellulose is not dissolved, most nutrients remain unavailable growth larvae. Further research should focus improved pretreatment thereby improve feasibility recycling method PPBS.
