Hydrolytic ageing or hydrolysis is the destruction of chemical bonds by action water. Among polymers most affected are polyamides, since PA6 hygroscopic, due to amide groups. with its interesting technical applications could be found in humid environments, which probably impedes durability. The estimation modifications that undergo has attracted attention several research subjects, have recorde...

This study focused on the valorization of different types waste biomass through biochar production at two pyrolysis temperatures (400 and 600°C). The feedstocks being used included three materials municipal origin, specifically sewage sludge organic fraction solid waste, agroindustrial grape pomace, rice husks exhausted olive pomace. scope research was to characterize resulting materials, in or...

olive oil extraction methods and technology can affect the quality and quantity of the extracted oil. in this study, qualitative and quantitative parameters were investigated for oil extracted using a hammer crusher at 720 and 1450 rpm at 30°, 40°, 60° c mixing temperatures. the data were analyzed using a complete randomized block factorial design using spss software with three replications. th...

Grape pomace is the main by-product of wine production that concentrates bioactive metabolites of polyphenolic nature with antibacterial activity. Since grape pomace composition varied depending on grape variety, climate, vineyard location, and winemaking technology, it is important to study the composition and antibacterial activity of each variety separately. In this study, antibacterial acti...

A process for the combined recovery of pectin and phenolic compounds from apple pomace, the primary by-product of apple juice production, was developed. The process includes extraction of dried apple pomace with diluted mineral acid and adsorption of phenolic constituents by a hydrophobic styrene–divinylbenzene copolymerisate. After elution with methanol, the polyphenolics were concentrated in ...

In this study, it was aimed to find the optimum condition for extraction of phenolic compounds from olive pomace by using high-pressure-assisted (HPAE). method, different pressure parameters (300–500 MPa), times (5–15 min), and ethanol concentrations (50–90% v/v) were used. According Box–Behnken design, 15 experimental runs performed total oleuropein contents. Also, HPAE compared with that clas...

Used for various high-tech applications, cerium is an important rare earth element (REE), and its sorption on solids also considering purification environmental radioactive waste disposal. In view of the industrial terms, it to remove Ce3+ ions from aqueous solution. Magnetite magnetic olive pomace nanocomposite were thus fabricated by a partial reduction co-precipitation approach. The structur...

The solid waste of olive oil extraction processes (olive pomace, OP) was converted into activated carbon (AC) by treating it with NaOH and then encapsulating within sodium alginate (SA) in beads crosslinking (SA-AC beads). prepared SA-AC were utilized as an adsorbent for the elimination recovery phenolic compounds (PCs) from mill wastewater (OMWW) following a zero liquid discharge approach to i...
