Enzymatic deinking for recycling of office waste paper

Journal of Environmental Chemical Engineering, 2017
Abstract Office waste paper constitutes an excellent low cost and high quality fibre source for the papermaking industry. Limitations in the application of conventional deinking to such paper are related to negative environmental impacts chemicals can cause, hence enzymatic deinking is receiving growing attention.

New approach to recycle office waste paper: Reinforcement for polyurethane with nano cellulose crystals extracted from waste paper

Waste Management, 2019
New approach to recycle office waste paper was purposed in this paper, i.e., cellulose nanocrystal (CNC) was extracted from waste paper and then used CNC as the organic filler to reinforce polyurethane elastomer (PUE) in thermal properties. A series of CNC/PUE nanocomposites was prepared in situ using a two-step process in solvent N,N-dimethylformamide

Empirical evaluation of cellulase on enzymatic hydrolysis of waste office paper

Biotechnology and Bioprocess Engineering, 2002
Enzymatic hydrolysis of waste office paper was evaluated using three commercial cellulases, Acremonium cellulase, Meicelase, and Cellulosin T2. Varying the enzyme loading from 1 to 10% (w/w) conversion of waste office paper to reducing sugar was investigated.

Converting untreated waste office paper and chitosan into aerogel adsorbent for the removal of heavy metal ions

Carbohydrate Polymers, 2018
The utilization of waste paper, an obsolete recyclable resource, helps to save resources and protect environment. In this paper, an aerogel was prepared to convert the waste paper into a useful material, which was used to adsorb heavy metal ions and handle water pollution.

Bioethanol Production from Office Waste Paper

International Journal of Science and Engineering Applications, 2023
In this study, office waste paper was utilized as the raw material for production of bioethanol. Experimental studies have been carried out cellulose to sugar by acid hydrolysis. Acid hydrolysis of waste paper to sugar was carried out 121?C with 5%(v/v) sulfuric acid with the volume of 100ml, 200ml and 5,10,15 g of office waste paper to obtain the best

Evaluation of eggshell wastes in office paper production

Biomass Conversion and Biorefinery, 2020
This study aimed to evaluate eggshell wastes, which have the potential to turn into high value-added products in paper industry. Membrane-removed eggshell wastes were subjected to certain processes of washing, drying, grinding, and sieving. The final product of eggshell calcium carbonate (ECC) was used in office paper production as filler, and its ...

Office waste paper as cellulose nanocrystal source

Journal of Applied Polymer Science, 2017
ABSTRACTCellulose nanocrystals (CNC) are isolated from office waste paper using an alkali solution and a subsequent acid hydrolysis process. The Fourier transform infrared spectroscopy and X‐ray diffraction (XRD) results demonstrate that ink and fillers used in the papermaking industry are almost totally removed after alkali treatments. The XRD results

Biological deinking technology for the recycling of office waste papers

Bioresource Technology, 1999
Abstract Results of the enzymatic deinking approach were demonstrated on a laboratory scale to provide a good quality deinked pulp from laser-printed alkaline office paper wastes. It has been suggested that, for alkaline papers, the majority of inks are localised on the paper coatings and fillers consisting mainly of CaCO3.

Waste to wealth: A sustainable and flexible supercapacitor based on office waste paper electrodes

Journal of Electroanalytical Chemistry, 2017
Abstract In order to develop a low cost, sustainable, and eco-friendly energy storage device, we demonstrated an all solid state symmetric flexible supercapacitor based on the office waste paper fibers-reduced graphene oxide-manganese dioxide (PF-RGO-MnO2) which acts as both the positive and negative electrodes. With the assistance of facile solution
