Given the current plastic disposal global crisis, biodegradable polymers may have an important role in leading way towards a more sustainable industry. Polyhydroxyalkanoates (PHA) are biobased and aliphatic polyesters synthesized by bacteria stored as intracellular granules. In this study, PHA was produced at pilot scale mixed microbial culture (MMC) fed with fermented fruit pulp waste. The acc...

The present study focused on the development of a methodology for production ethanol from fermentation waste resulting citrus fruit processing. experimental design included number steps, each optimized to make whole process cost-effective, energy-saving, and ecofriendly. Particular emphasis was given pretreatment (CW), which carried out through combination physical means, namely milling, heatin...

Abstract The feedstock seasonality has been poorly studied in the anaerobic digestion process. could disturb process stability, mainly for fruit and vegetable waste. In this study, three seasonal waste mixtures generated wholesale markets were reduced to 10, 6, 4 mm assess influence of particle size reduction on biodegradability. methane yield ranged between 298 465 mL CH g VS −1 (volatile soli...

Abstract Purpose Objective of this study is the valorisation mass rearing waste fruit flies from sterile insect technique facilities by black soldier into high quality and quantity products as a sustainable utilisation concept. Methods Different ratios medfly in hen feed were used for solder fly (BSF) larvae. The growth rate survival determined. Moreover, gains determined bioconversion rates as...
