Reading Assignment Chapter 10: Recovered Paper Chapter 11 : Glass W aste Chapter 12 : Textile Waste Chapter 13 : Chemicals in W aste: Household Hazardous W aste Unit Lesson Do you recycle? Do you know what materials should be recycled and how to recyc le them? Recycling is an important part of protecting and preserving our world’s resources. All too often, resources that could be recycled and reused are thrown away and destroyed, leading to the need to find and use more resources.

Think green , and help our world. Recovered Paper Think of the amount of paper you receive in junk mail. Add to that all of the paper used in offices, homes, and schools around the world, and it becomes easy to see why recycling paper is important to conserve resources. UNIT III STUDY GUIDE Introduction to Waste Managem ent, Regulation, Collection, and Green Engineering BEM 3601, Waste Management 2 UNIT x STUDY GUIDE Title Paper is the largest fraction of the municipal waste stream, and for every ton of paper recycled, about 2m 3 of landfill space is saved (Scott, 2011) . Not all paper is equally useful in the recycling process. There are three main categories of recycled paper :  post -consumer recycled fiber ,  pre-consumer recycled fiber , and  broke paper . Post -consumer recycled fiber has already been used by the consumer. It is the most contaminated and of the lowest quality. Pre -consumer recycled fiber is recycled during the manuf acture of other paper products, such as envelopes. Lastly, broke paper is recycled internally within the paper mill (Scott, 2011). As we learned in Unit II, metals can be recycled again and again without a reduction in quality in the final product. The sa me does not apply to paper. Each time it is recycled, it becomes more and more degraded. Scott (2011) states that increasing the amount of recycling will require increasing collection of the most degraded and contaminated grade of paper, which is post -cons umer waste. This will require better recycling technologies to process the higher levels of contamination. To increase the amount of paper that is recycled, we may just have to be sure recycling containers are always in close proximity. In one study, rese archers placed a recycling bin in a central location in an office and informed workers of the bin by memo. Only 28% of paper was recycled. When the bins were placed on worker’s desktops, 85% to 94% of paper was recycled (Brothers, Krantz, & McClannahan, 19 94). Perhaps this study says more about laziness than recycling, but it is instructive nonetheless! Glass Waste The main environmental impacts of glass production are the high use of energy in the batch melting process and the gaseous emissions from fuel combustion. Container and flat glass are good candidates for recycling because they are chemically uniform and widely used (Butler & Hooper, 2011). Many municipalities recycle glass, and container glass recycling is similar to metal recycling , in that th ere is no limitation on the number of times that used container glass can be fed back into the raw material input cycle ( Butler & Hooper, 2011). Flat glass from building windows and vehicle windows is not often recycled. A 2001 report for the Center for Su stainable Systems estimates that there are 4.45 x 10 5 tons/year of glass that could be recycled from vehicles (As cited in Butler & Hooper , 2011 , p. 159 ). Textile Waste Approximately 20 million tons of textiles are sent to landfills every year, so there is ample opportunity for recycling textiles ( U.S. EPA , 2013). We may not often think of recycling our clothes, but every time we drop off our old clothes at a donation bin, we are sending them off to be reused or recycled. Textiles can be recycled in seve ral ways. Synthetic fibers can be melted or dissolved , and new fibers can be produced. In a more complicated process, the structure of the fiber can be preserved. Fibers can also be ground and used in a variety of ways, including in asphalt (Bartl, 2011). Lastly, polymers can also be recycled chemically, where they are then used to produce new fibers or dyes. Chemicals in Waste: Household Hazardous Waste Have you ever started to throw something in the trashcan only to stop and ask yourself , what should I do with this ? Perhaps it was a battery, medication, a light bulb, a solvent, or used motor oil. Such wastes are categorized as household hazardous waste (HHW). Although HHW is a small portion of the municipal waste stream, its toxic chemical characteristi cs make it a significant threat to human and ecological health. BEM 3601, Waste Management 3 UNIT x STUDY GUIDE Title In many cases, HHW ends up in landfills. Although modern landfills are constructed with liners and leachate collection systems, these are not foolproof. Slack and Letcher (2011) state that co mputer modeling of the consequences of a degraded engineered barrier system found that some inorganic contaminants could exceed reporting levels decades to centuries later. Therefore, regulation of these wastes is important. HHW is not covered under Subti tle C of the Resource Conservation and Recovery Act (RCRA). It is regulated under Subtitle D, which covers solid waste management (Slack & Letcher, 2011). Many communities offer household hazardous waste collection, but of course, not everyone takes advant age of these programs. References Bartl, A. (2011). Textile waste. In T. M. Letcher, & D. A.
