A composting toilet using sawdust as a matrix has the potential to trap pathogens that might occasionally be contained in human feces. Therefore, care should be taken when handling the sawdust. It should also be noted that pathogenic viruses tend to have stronger tolerance than pathogenic bacteria. The fates of several species of coliphages, T4, lambda, Qbeta and MS2, in sawdust were investigat...

This paper presents the results of Pb2+ adsorption from synthetic Pb(NO3)2 solutions, using beech sawdust and wheat straw as adsorbents. Physicochemical characterization adsorbents included specific surface area, pHpzc, SEM-EDS FTIR analysis. Adsorption kinetics isotherms, well changes in pH solution during process, were monitored analyzed. The showed that is explained by pseudosecond order kin...

Biofuel pellets were prepared from biomass (pine, chestnut and eucalyptus sawdust, cellulose residue, coffee husks and grape waste) and from blends of biomass with two coals (bituminous and semianthracite). Their mechanical properties and combustion behaviour were studied by means of an abrasion index and thermogravimetric analysis (TGA), respectively, in order to select the best raw materials ...

Abstract The wastewater from industry is contaminated with dyes, which should be removed in order to prevent environmental damage. This paper presents a method for removing methylene blue an aqueous solution using fixed-bed adsorption process onto sawdust. In the article, of continuous measurement concentration sorption on sawdust was used. results were compared obtained by standard periodic te...

Carbon materials were obtained by pyrolysis of the sawdust of Algarroba wood under CO2 or N2 atmospheres at temperatures from 200oC up to 900oC. Carbon materials were characterized by surface and micropore areas, volume pore and mean pore diameter. An approach of the kinetic parameters (apparent constant-rates and activation energies) associated with the synthesis of these carbon materials is a...

Highly microporous bio-based activated carbon fibers (ACFs) were prepared through a simple reactivation method. Sawdust, as the starting material, was liquefied and melt-spun to produce the precursor fibers. Then, the precursor fibers were activated by KOH and reactivated by steam. By varying the conditions of the two activation processes, the formation mechanism of the pore structure was studi...

The main objectives of the experiment were: 1) to compare bacterial populations of mastitis-causing organisms on the teats of lactating dairy cattle housed on sand and sawdust bedding and, 2) to examine the relationship between bacterial counts present in the 2 bedding types with those on teat ends. Sixteen lactating Holstein cows were housed on either sand or sawdust-bedded free stalls using a...

This report describes a green chemical method for controlling soil-borne plant diseases without disinfection using an equimolar copolymer of N-benzyl-4-vinylpyridinium chloride with styrene (PBVP-co-ST) that captures microbial cells alive on the surface and is highly biodegradable. Tomato bacterial wilt caused by Ralstonia solanacearum was controlled by the addition of sawdust coated with PBVP-...

To produce fruiting bodies of Oudemansiella mucida, porcelain fungus, on the oak sawdust medium, additives suitable for the mycelial growth and fruiting body formation were screened. In general, the mycelial growth of the three strains of O. mucida used in this study have been good on oak sawdust mixed rice bran of 20~30%. The mycelia incubated in potato dextrose broth for 7 days were inoculate...
