Rice Husk Bio-Chars as Adsorbents of Contaminants from Water

Biobased adsorbents are eco-friendly materials used for water and wastewater treatment and air cleaning. This research work explores the potential use of rice husk chars as a low-cost adsorbent for pollutants from...

Using Oxone and TAED activator in non-chlorine bleaching of soda bagasse pulp

Bagasse fiber has been used in the production of bleached chemical pulp by the Pars Paper Company. In this company, a conventional three-stage sequence of hypochlorite, alkaline extraction and second hypochlorite (HEH)...

Topochemical fractionation of lignin and polysaccharides

Sugarcane bagasse is abundant agro-industrial waste that can be potentially utilized as a source of valuable compounds and biopolymers. In the present study, sugarcane bagasse from Brazil was fractionated employing an environmentally...

Ionic Liquids — Promising but Challenging Solvents for Homogeneous Derivatization of Cellulose

In the past decade, ionic liquids (ILs) have received enormous interest as solvents for cellulose. They have been studied intensively for fractionation and biorefining of lignocellulosic biomass, for dissolution of the polysaccharide,...

Topochemical characterisation of sugar cane internodes

Biomass pretreatments and subsequent conversion to fuels and materials involve a multitude of topochemical interactions. Detailed knowledge about changes in surface composition of biomass caused by pretreatments allows tailoring of biomass processing...

HyCellSolv pretreatment to enhance cellulose dissolution in water based solvents

Cellulose dissolution in water-based solvents is essential for processing of regenerated cellulose products such as fibres, films and particles. Cellulose dissolution in NaOH–urea aqueous solution has emerged as a simple and attractive...
