Fire-Retarding Ceiling Panel from Recycled Paper Waste

panel manufacturing from tetrapak waste

nowadays, tetrapack packaging materials are widely used in beverages such as juice, milk and water packaging applications. each year a significant amount of waste is producing in the world which are non-recyclable in other industries and will also cause environmental pollution. this paper outlines the panels made from tetrapack waste and investigation of physical and bending properties of these...

Ethanol production of semi-simultaneous saccharification and fermentation from mixture of cotton gin waste and recycled paper sludge

Ethanol production from the steam-exploded mixture of 75% cotton gin waste and 25% recycled paper sludge in various conditions was investigated by semi-simultaneous saccharification and fermentation (SSSF) consisting of a pre-hydrolysis and a simultaneous saccharification and fermentation (SSF). Four cases were studied: 24-h pre-hydrolysis + 48-h SSF (SSSF 24), 12-h pre-hydrolysis + 60-h SSF (S...

Enzymatic Production of Glucose from Waste Paper

Municipal wastes have become a severe problem in developed and developing countries during the last century, paper being the main constituent. Not all of the waste paper can be recycled, and therefore alternative procedures for the use of the remaining material should be pursued. The aim of the present work was the application of cellulases for waste paper treatment and the subsequent glucose p...

Recycled paper visual indexing for quality control

In this paper, we describe the development of a system for evaluating an specific quality characteristic of recycled paper sheets using techniques of image analysis and pattern recognition. We call Bumpiness the phenomenon of interest, which is new in the literature on paper quality. This phenomenon is characterized by the appearance of macroscopic undulations on the paper sheet surface that ma...
