The fermentation characteristics of six specific types of the organic fraction of municipal solid waste (OFMSW) were examined, with an emphasis on properties that are needed when designing plug-flow type anaerobic bioreactors. More specifically, the decomposition patterns of a vegetable (cabbage), fruits (banana and citrus peels), fresh leaf litter of bamboo and teak leaves, and paper (newsprin...

Corn stalk, an agricultural waste, was valorized by the production of cellulose nanofibers (CNF), which were tested for improving recycled paper properties. CNF from eucalyptus kraft pulp (E-CNF) was used as a reference. Addition of 0.5% wt. CNF produced from corn organosolv pulp (C-CNF) to recycled paper increased the tensile index by 20%, whereas the same improvement with E-CNF was achieved a...

in the present research, the effect of different peroxide charges and reaction times were investigated inhydrogen peroxide bleaching of mixed old newsprint and old magazine deinked pulp. in thebeginning, mixed recycled papers were pulped using conventional method and then deinked byflotation. in addition, deinked pulps (mixture ratio of 70% onp and 30% omg) were bleached withhydrogen peroxide a...

The U.S. antitrust agencies have long evaluated mergers in homogeneous product markets to determine “whether the merged firm will find it profitable unilaterally to suppress output and elevate the market price.”[1] But the U.S. Department of Justice had not publicly disclosed a formal economic method to analyze output suppression concerns until 2007, when it required two large newsprint manufac...

the aim of this study was to determine the effect of age on fiber characteristics of one-humped female camels of semnan province. 50 grams of wool samples from the left midside area were randomly collected from 28 camels of three different age groups: young, adult and old and fibre characteristics were measured. statistical model used for this research was completely randomized design (crd). an...
