As in the prior art, the outer surfaces of each set should have a release coating such as a fluorocarbon. The layer of hot-melt adhesive includes, by weight: 20-50% thermoplastic copolymer, 15-50% tackifying resin, and * 20-60% wax having a melting point of at least 60 C. As soon as the adhesive has cooled below its softening point, the stack can be fanned, thus breaking it into sets. Fanning can usually be performed within 45 seconds, because there is no need to wait for the adhesive to dry as has been necessary with the aqueous adhesives that have been used in the prior art. -

Alternative Use of Deinking Sludge As a Source of Fibers in Fiber-Cement Manufacture
CORE Metadata, citation and similar papers at core.ac.uk Provided by EPrints Complutense CELLULOSE CHEMISTRY AND TECHNOLOGY ALTERNATIVE USE OF DEINKING SLUDGE AS A SOURCE OF FIBERS IN FIBER-CEMENT MANUFACTURE ANGELES BLANCO, CARLOS NEGRO, ELENA FUENTE and LUIS MIGUEL SÁNCHEZ Department of Chemical Engineering, Chemistry Faculty, Avda. Complutense s/n 28040 Madrid, Spain The present paper, contributing to solving two different problems related both to the chemical industry and the environment, is a feasibility study on the utilization of the deinking sludge (the most important waste from papermaking) as a raw material for fiber-cement manufacture, in which asbestos has been recently replaced by other fibers because of the hazard it induces. The results obtained show that the use of deinking sludge as a source of cellulose in fiber-cement manufacture is feasible and could improve product strength, if 5% of the virgin fibers are replaced by fibers and fines from the deinking sludge. It is also possible to replace up to 10% of the virgin fibers, with no loss in product strength. These results, if confirmed on a mill scale, would improve the economy of the process, as due to lower waste costs. Keywords: fiber-cement, deinking sludge, recycling, waste management, sustainability, papermaking wastes INTRODUCTION As known, papermaking is an industry However, recycling operations, espe- leader from the standpoint of recycling and cially deinking, generate an important sustainability, the main reason being that quantity of wastes, representing 70% of the virgin and recycled fibers can be used wastes produced by the European pulp and together, sometimes contributing with paper industry. -
The Pulp Invasion – Thailand
CHRISLANG.ORG Join the transformation C The Pulp Invasion – Thailand By Chris Lang, published by WRM, December 2002. Back to contents (https://chrislang.org/2002/12/01/the-pulp-invasion-the-international-pulp-and- paper-industry-in-the-mekong-region/) THAILAND: The fast-growing pulp and paper industry This report looks at the expansion of the pulp and paper industry in Thailand. It starts with an overview of the industry today. Rather than providing a reliable source of paper needed by the people of Thailand, however, the industry today is dependent on imports, exports and lavish subsidies from the government and international “aid” agencies. The Thai government has actively supported the development of the industry, through subsidies, pro- cash crop and plantation policies, tax relief and favourable import duties on machinery imports. The second section looks at some of the government support, and includes a brief introduction to some of the background political situation in the country during the early 1990s. The third section looks at some of the international support to the industry in Thailand, largely through multilateral and bilateral “aid”. The fourth section looks at some of the Thai companies involved in the pulp and paper sector. While they have made profits, they have also run up enormous debts. This, accompanied by the economic crisis in 1997, has opened the door for international companies to buy up shares in Thai companies. Some of these companies are also profiled in this section, along with international consultants who provide advice and legitimacy for the industry. Associated with the expansion of the pulp and paper industry, the area of fast-growing tree plantations has also expanded, often with disastrous impacts for many local communities. -

Benefits of Polycups Stock Over Other Waste Paper Grades in Paper Recycling
EDITORIAL bioresources.com Benefits of Polycups Stock over Other Waste Paper Grades in Paper Recycling Avdhesh K. Gangwar It is never too late or too early to invent alternative processes for the betterment of our routine life. For paper production, trees are being cut in huge quantities each day, and this directly affects our day to day life by making atmospheric conditions less favorable. Waste paper can be recycled on average 4 to 6 times while maintaining acceptable qualities in recycled paper. To save forest resources, we should move ahead towards using more and more waste paper for paper production. A wasted resource can be recycled either to make the same product or by manufacturing new products, e.g. cardboard boxes, newspaper, writing and printing papers, and paper bags, etc. Several waste paper grades are not being fully utilized, and their use might allow increased paper recycling to produce new recovered paper with specified paper qualities. Polycup stock is an example of an under-utilized type of wastepaper that has the potential to substitute effectively for virgin pulp production. Keywords: Deinking; Paper grades; Paper recycling; Polycups Contact information: Department of Biotechnology, Thapar University, P. O. Box 32, Pin- 147004, Patiala, India; [email protected] Recycle more to save our environment, but is it really easy to do? This editorial considers a way to minimize waste by using a neglected waste paper grade for the manufacture of paper. Ordinarily, for this to happen, adequate deinking of recycled fibre is needed to remove all ink and other unwanted materials from the secondary fibres.
