Recycling Waste Paper

Considerable progress lias been made during the past decade for recycling paper wastes, which according to Table 4 constitute well over one-third of the typical municipal waste produced.

Coal used in power stations has the potential to be partly replaced by fuels derived from pre-treated plastics and paper waste, reducing both dependency on fossil fuels and reliance on landfill. APME reports on a project in the Netherlands which it co-sponsored to develop a substitute fuel from plastics. The environmental assessment of the project compared the environmental impacts of coal substitution with other plastics recovery methods, including gasification in feedstock recycling and energy recovery from plastics waste in cement kilns. The study also compared coal substitution with the generation of power from burning biomass. 

Contaminant removal processes depend on the type and source of secondary fiber to be pulped. Mill paper waste can be easily repulped with minimal contaminant removal. Recycled postconsumer newspaper, on the other hand, may require extensive contaminant removal, including deinking, prior to reuse. Secondary fiber is typically used in lower-quality applications such as multiply paper-board or corrugating paper. 

The Commission is working on establishing end-of-waste criteria for a number of specific recyclable materials including metal scrap of copper, aluminum and iron, waste paper, waste glass, compost, and plastics. Based on the results of two frontrunner studies, ferrous scrap and aluminum scrap in 2010, the first... 

In the latter half of the twentieth century, paper wastes, which make up a major fraction of domestic garbage (mostly in the form of corrugated cardboard, newspapers and office papers), have placed severe strains on the capacity of municipalities to dispose of them (typically in sanitary landfills). This, in addition to concern over excessive harvesting of forests to feed pulp mills, has generated a requirement for the recycling of used paper. 

Today, we use an enormous amount of paper—about 70 million tons a year in the United States alone. That s about 230 kilograms, or six full-sized trees, for each U.S. citizen. Currently, we recycle only about 25 percent of the paper we use. The rest we throw away. This is unfortunate because recycling paper does more than just save trees. A lot of energy is required to make paper from a tree. Less than half as much energy is needed to process old paper into new. Remarkably, about 50 percent of the solid waste produced in North America is paper. What have you done with your 230 kilograms this past year ... 

Diazo Components With Amino alkyl Groups. Yellow dyes are prepared by ami-nomethylation of 2-(4 -aminophenyl)-5-methylbenzothiazole followed by diazoti-zation and coupling with acetoacetarylides. Red cationic dyes are obtained with naphthols or hydroxynaphthoic acid arylides. All are suitable for dyeing paper. The bleachability of these dyes is important for the recycling of waste paper [84], The aminomethylation of aromatic amines is carried out by reaction with formal-... 

Because of the large volume of wastewater generated in hydraulic debarking and the problems associated with recycling it, waste treatment and disposal techniques used by the pulp and paper industry are applicable. This involves the employment of heavy-duty clarifiers to remove suspended solids, followed by biological treatment to remove oxygen-demanding substances. 

Linpac, Recycle Paper Mill, Cowpens, South Carolina The first full-scale commercial pressurized ozone membrane filtration system was tested and installed in the Linpac recycle paper mill in Cowpens, South Carolina (Table 35.1) for TDS removal [50]. The mill produces linerboard and medium for the production of corrugated boxes from an OCC and mixed office waste (MOW) furnish. The mill has no liquid discharge stream. 

In some cases, the advantage of a sustainable product is specific and readily observable by the customer, such as a Post-it Recycled Paper Notes, made with 100 percent recycled paper fiber (20 percent post-consumer waste). 3M paint replacement films, which allow automobile and aircraft manufacturers to reduce their use of paints and solvents, are an example of an industrial application where the customer is striving to achieve its own sustainability goals.
