Deep eutectic solvents (DESs) for cellulose dissolution: a mini-review, Yang-Lei Chen et al, Cellulose , Vol.26 (1). Deep eutectic solvents (DESs), which are a novel class of sustainable designer solvents, have attracted considerable attention in the field of cellulose chemistry. Due to their low cost and analogous physico-chemical properties to ionic liquids, DESs are expected to be alternative solvents for dissolving cellulose. However, at present, the solubility of cellulose in DESs is much lower than in most ionic liquids. In this mini-review, we briefly summarise the current state of knowledge about cellulose dissolution in DESs. Non Ǧ Wood Plant Fibers: Applications in Pulp and Papermaking, JE Atchison - Encyclopedia of Plant and Crop Science (Print), 2019. Originally paper was being made from non-wood materials such as papyrus, hemp and textile rags. With the development of technologies for isolating pulp from wood, it resulted in abandoning paper making from many non-wood materials. In this paper we have reviewed the trend in pulp and paper production from different non-wood materials since the perception of the paper making technology up to date through literature review and consultations with experts in the area of pulp and paper production. Cleaner approach for improving the papermaking from agro and hardwood blended pulps using biopolymers, S Bhardwaj et al, Journal of Cleaner Production , Vol.213. Due to rapid deforestation, the paper industry is facing problems like shortage of forest based raw materials, cost increment and negative effects on the environment including increasing air, water and soil pollution. In India, agro residues utilised in stubble burning could be used as a sustainable fibre resource for papermaking, but the paper made from these possesses poor strength properties. Considering the multiple advantages of using agro residues and weak strength properties of the paper made from these, this study was conducted. The effect of blending hardwood pulp and agro pulp with cationic starch or chitosan at wet-end of papermaking with and without subsequent surface sizing using oxidized starch was explored. Approaches for converting sugarcane trash, a promising agro residue, into pulp and paper using soda pulping and elemental chlorine-free bleaching, NK Bhardwaj et al, Journal of Cleaner Production , Vol.217. Industrialisation and urbanisation are the key drivers to threaten the environmental quality and natural resources. Traditionally, pulp and paper industry has been highly reliant on forest based resources for its escalation. Shortage of forest based raw materials, strict environmental regulations and policies have compelled the industry to seek for alternate raw materials for its production. Mills are now focusing on exploring the potential of different agro wastes such as cereal straws and bagasse etc. In present research, sugarcane trash, one of the most abundant agro residues in India, was investigated for its capability in pulping and bleaching. RECYCLING Optimal scheduling ratio of recycling waste paper with NSGAII based on deinked- pulp properties prediction, Wenhao Shen et al, Computers & Industrial Engineering , Vol.132. The recycling of waste paper has been an effective way to achieve the environmental-friendly growth of papermaking industry. Focusing on the mixed-pulping process which has been generally employed, to ensure the required properties of the deinking pulp (DIP) and minimise the purchase cost of waste paper, an intelligent model scheduling the mixing ratio of waste paper was developed in the study.
