Olea europaea L. leaves constitute a source of bioactive compounds with recognized benefits for both human health and technological purposes. In the present work, different extracts from olive were obtained by application two extraction methods, Soxhlet microwave-assisted (MAE), six solvents (distilled water, ethanolic glycerol mixtures solvents). MAE was applied under 40, 60 80 °C 3, 6.5 10 min. The effect method, solvent treatment factors (the latter in MAE) on total phenol content (TPC),...
Soda black liquors from the Specel® process, which used wheat straw as raw material, were subjected to an acid precipitation process recover lignin. Lignin was isolated by using three different inorganics acids (H3PO4, H2SO4, and HCl) at concentration levels, pH values of 2 4. Even though highest lignin yield achieved phosphoric acid, most economical inorganic sulphuric acid. Physico-chemical characterizations precipitated samples performed differential scanning calorimetry (DSC),...
Anaerobic digestion of agro-industrial and livestock waste generates considerable digestate volumes that are important sources nitrogen (N). However, on some occasions, the high concentrations N present in digestates may represent an obstacle to its use locally as fertilizer, since it can cause environmental impact (EC, 2000). This study analyzes efficiency gas-permeable membranes (GPM) recovery ammoniacal (NH4+) swine manure (SM, Control) three generated from anaerobic co-digestion mixtures...
The application to agriculture of wheat-straw spent mushroom substrate amendments (compost/vermicompost) used grow Pleurotus ostreatus has been analyzed. study was conducted in a vineyard where the effect on (1) physicochemical properties soil and leaf (2) analytical characteristics aromatic composition wine were resulted an increase organic matter macronutrients (NO3−, P2O5 K2O) soil. With regard leaves, NO3− K2O contents those vines fertilized with vermicompost higher, metallic content...
The influence of the variables soda (0.5-3.0%), hydrogen peroxide (1.0-6.0%) and time (1-5 h) in bleaching pulp empty fruit bunches (EFB) from oil-palm, on properties bleached pulps, was studied. Polynomial neural fuzzy models reproduced results brightness, kappa number, viscosity pulps with errors less than 10%. By simulation pulp, using polynomial models, it possible to find optimal values operating variables, so that differed only slightly their best yet save chemical reagents, energy,...
The aim of this work is to characterize banana tree residues and use it in pulping combustion processes. soda-anthraquinone the can be simulated by polynomial models, then predict pulp properties (yield, Kappa number, viscosity brightness) as a function operating variables (temperature 160 180°C, time 40 60 min soda concentration 7.5 12.5%) with errors less than 20%. Operating under optimal conditions (160°C, 7.5% soda), 39.23% yield, 28.59 48.25% brightness, 1149 ml/g viscosity, 48.0 Nm/g...
Compost made from municipal solid waste (MSW) contains heavy metals that can interfere with the use of organic amendment in soil. In order to find effective ways reduce potential risk metals, we have investigated a novel approach by acid during MSW composting. Citric and oxalic dissolutions (0.25 mol x (-1)) were used at determined ratios (kg dried MSW: cm(3) acid). Cr Ni concentrations similar compost, independent contribution. By contrast, Cu decreased 63% (at citric ratio 1:15), 65% 1:20...
ResumenEn este trabajo, se describe el proceso de compostaje mediante pilas volteadas la fracción orgánica, recogida selectivamente, residuos sólidos urbanos (RSU), analizado durante tres años.El compost, aceptable para su uso agrícola, fue aplicado en cultivos trigo y ajo, combinando tratamientos mixtos con objetivo conocer que tipo fertilización era generaba los mejores resultados, demostrar como orgánica puede llegar a ser una alternativa real nuestros suelos consiguientes beneficios...
The use of biomass resources different from conventional wood materials fosters the sustainable growth paper industrial sector and finds a development path in line with concept circular bioeconomy.In this work, six nonwood (Leucaena leucocephala, tagasaste, rice straw, Paulownia fortunei, Hesperaloe funifera empty fruit bunches) were tested compared to Eucalyptus globulus for production under Kraft conditions.All raw chemically characterized determine holocellulose, cellulose, Klason lignin,...
Influence of variables [soda, (0.5 to 3.0%), hydrogen peroxide (1.0 10.0%) and time (1 5 h)] in the bleaching soda pulp Hesperaloe funifera, on properties bleached pulps, was studied. Polynomial neural fuzzy models had reproduced results Kappa number, brightness viscosity pulps with errors less than 10 15%, respectively. By simulating process H. polynomial models, optimal values operating can be found, so that differ little from their best instead will save chemical reagents, energy plant...
