Briefing Paper: Waste Prevention
This paper examines waste prevention – the “reduce, reuse” part of the solid waste management hierarchy. It summarizes research findings on prevention – some generated as background papers in 2007 as part of DEQ’s Waste Prevention Strategy development — and supplements with a more recent literature review. DEQ’s Waste Prevention Strategy is also summarized. This paper concludes with a status re...
متن کاملEnzymatic 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...
متن کاملChromaticity based waste paper grade identification
In recycling, waste papers are segregated into various grades as they are subjected to different recycling processes. Highly sorted paper streams facilitate high quality end products and save processing chemicals and energy. Automated paper sorting systems offer significant advantages over human inspection in terms of worker fatigue, throughput, speed, and accuracy. As a consequence, many autom...
متن کاملWaste Paper - Promissing Feedstock for Bioethanol Production
Modern approach to utilization of non-edible biomass is its conversion to glucose, and the following fermentation of the sugar into final bioproducts. Among various biomass types, the waste of office paper is distinguished by increased content of cellulose and negligible content of lignin; therefore it can be a suitable feedstock for bioconversion into valuable bioproduct, e.g. ethanol. An adva...
متن کاملCarbon dioxide and ammonia emissions during composting of mixed paper, yard waste and food waste.
The objective of the work was to provide a method to predict CO2 and NH3 yields during composting of the biodegradable fraction of municipal solid wastes (MSW). The compostable portion of MSW was simulated using three principal biodegradable components, namely mixed paper wastes, yard wastes and food wastes. Twelve laboratory runs were carried out at thermophilic temperatures based on the princ...
