Degradabilities of four kinds of commercial biodegradable plastics (BPs), polyhydroxybutyrate and hydroxyvalerate (PHBV) plastic, polycaprolactone plastic (PCL), blend of starch and polyvinyl alcohol (SPVA) plastic and cellulose acetate (CA) plastic were investigated in waste landfill model reactors that were operated as anaerobically and aerobically. The application of forced aeration to the l...

The significant effect of the addition very small proportions nanofibres and nano-particulates on physical mechanical properties solid materials has been long observed described. electrospun fibres liquid not so widely examined. In this paper, polyvinyl alcohol (PVOH), zein nanofibers in sunflower (Helianthus annuus) oil its viscosity was quantified. For a given amount material, trend increasin...

Valorization of lignocellulosic waste residues in the development of potential biodegradable composites has been of recent research interest. Recent research has shown that wheat straw can be used as a reinforcement material for the synthesis of novel polyvinyl alcohol (PVOH)based composites. However, certain pretreatment methodology needs to be used for the selective removal of the lignin comp...

thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...

Thermomechanical pulp (TMP) fibers, generally used to produce newspapers and carton materials, have poor inter- and intra-fiber bonding contributing to low strength properties. Poly(vinyl alcohol) (PVOH) was applied as a co-additive of 1,2,3,4-butanetetracarboxylic acid (BTCA), in the presence of sodium hypophosphite (SHP) as a catalyst, to esterify paper sheets based on TMP fibers. Fourier tra...

In this study, we prepared composites made from polyvinyl alcohol (PVA), sodium alginate (SA), curcumin (Cur), and polydopamine (PD). The film-forming properties of the were researched for potential wound-healing applications. structures polymer blends studied by FTIR spectroscopy microscopic observations (AFM SEM). mechanical measured using a Zwick Roell testing machine. It was observed that f...

Mulch films increase soil temperature, maintain moisture, improve water and fertilizer absorption, reduce weed growth. This work studied a mulching film made using polyvinyl alcohol (PVA) lignin extracted from empty fruit bunches (EFBs). The mulch were investigated for opaqueness, biodegradation, water-solubility, mechanical properties. Life cycle assessment (LCA) cost estimate analysis conduct...
