The conversion of lignocellulosic agricultural waste into biofuels and other economically valuable compounds can reduce dependence on fossil fuels, harmful gas emissions, support the sustainability natural resources, including water, minimize amount in landfills, thus reducing environmental degradation. In this paper, wastes biomethane, biohydrogen, biodiesel, bioethanol, biobutanol, bio-oil is reviewed, with special emphasis primary secondary residues as substrates. Some novel approaches are mentioned that offer opportunities to increase efficiency valorization, e.g., hybrid systems. addition physical, chemical, biological pretreatment waste, some combined methods mitigate negative effects various recalcitrant processing (alkali-assisted thermal pretreatment, hydrolysis alkali bioaugmentation) evaluated. addition, production volatile fatty acids, polyhydroxyalkanoates, biochar, hydrochar, cellulosic nanomaterials, selected platform chemicals from described. Finally, potential uses recovered products discussed.

Coffee waste-derived biochar as a flame retardant for epoxy nanocomposites

Sustainable materials and technologies, Год журнала: 2024, Номер 41, С. e01079 - e01079

Опубликована: Авг. 9, 2024

Starting from spent coffee grounds, the use of coffee-derived biochar (CB) as a flame retardant (FR) additive was explored following waste-to-wealth approach. CB employed alone and in combination with ammonium polyphosphate (APP) ternary (Si-Ti-Mg) mixed oxide to enhance thermal, fire, mechanical performances bisphenol A diglycidyl ether (DGEBA)-based epoxy resin modified (3-aminopropyl)-triethoxysilane (APTES) cured cycloaliphatic amine hardener. The presence silicon-modified chains guaranteed uniform distribution throughout resin. combined FR action fillers (CB, APP, Si-Ti-Mg oxide) acidic characteristics hybrid moieties enabled achievement no dripping UL 94-V-0 classification for containing 20 wt% 1 phosphorus loading, significantly increasing flexural modulus (by ∼15%). Although it is not self-extinguishing, compared pristine resin, nanocomposite filled only exhibited remarkable decrease peak heat release rate (pHRR) ∼65%) beneficial smoke suppressant effect notable (∼11%) total production. Cone calorimetry tests, pyrolysis combustion flow analysis, microscopy measurements helped outline mode CB, retardation highlighting strong condensed phase, formation stable aromatic ceramic char, well character due basic nature metal ability porous adsorb generated gases.

Generation of Microplastics from Biodegradable Packaging Films Based on PLA, PBS and Their Blend in Freshwater and Seawater

Polymers, Год журнала: 2024, Номер 16(16), С. 2268 - 2268

Опубликована: Авг. 10, 2024

Biodegradable polymers and their blends have been advised as an eco-sustainable solution; however, the generation of microplastics (MPs) from degradation in aquatic environments is still not fully grasped. In this study, we investigated formation bio-microplastics (BMPs) changes physicochemical properties blown packaging films based on polylactic acid (PLA), polybutylene succinate (PBS) a PBS/PLA 70/30 wt% blend after different media. The tests were carried out two temperature/light conditions to simulate either warm water, under sunlight exposure (named Warm Light—W&L), cold deep water Cold Dark—C&D). pH aqueous evaluated, while formed BMPs analyzed for size shape alongside with variations polymer crystallinity, surface mechanical properties. W&L conditions, all films, hydrolytic led reorganization crystalline phases, strong embrittlement increase hydrophilicity. exhibited increased resistance respect neat PLA PBS films. C&D no microparticles observed up 12 weeks degradation.
