Solid Waste Management Essay

Paragraph 1 The research done by Haines on how the atomic structure of FePO4 varies when temperature increases from 294K to 1073 shows few crystal chemical relationships between SiO2 and FePO4. There is a first order variation of cell parameters and atomic orientations with temperatures lower than 980K and α-phase plays a dominant role over β-phase at high temperature. For the α-phase FePO4, the cell parameters increase with a non-linear trend when temperature increases linearly. The volume of the cell expands with a thermal expansion coefficient of α (K-1 )=2.924x10-5 +2.92x10-10 (T-300)2 . The reasons for the cell expansion are the cell angular variations and tilt angles, which were caused by the variations in Fe-O-P bridging angles as they are not symmetrical. The δ and θ changes with functional relationships when temperature changes. The variation of the average of δ and θ versus temperature was studied in the paper. In terms of the crystal chemical relationship between quartz SiO2 and FePO4, the Fe-O distance in the tetrahedral phase decreases with increasing temperatures. The very alike situation happens in Si-O distance in α-quartz with increasing temperatures. As the fact there are many variations caused by temperature increases, energy increases and vibrations, the non-physical behavior could be used for analysis of all the disorders. From the research, the equation of δ2 =2/3 δ0 2 [1+(1-3/4(T-Tc/T0-Tc) ^1/2] shows the changing correlation of tilt angle…

During the extraction process, the sand bath was set to 20℃. The 1.00 gram of ground nutmeg was transferred to the round-bottom flask (RBF) using the plastic funnel. Three milliliter of tert-butyl methyl ether and two or three boiling chips were added into the flask. The black plastic connector was used just like the distillation column with air condenser set-up. The flask was clamped to the ring stand using 3-pronged clamp. The flask was lowered into a slightly depression in the sand without…

The melting point of a substance is best described as the temperature at which a solid becomes a liquid (Bruice 2014). On the molecular level, when a compound melts the forces between the molecules become weaker. This is because when a substances heats up the kinetic energy between the molecules increase causing the molecules to vibrate. When the vibrations become strong enough for the molecules to move around and pass other molecules, the compound that is being heated up starts to melt and…

Spolia refers to the repurpose, or reuse of structural or decorative components from one piece, to another. Spolia, or “the spoils of war” is seen on a lot of different artworks, or monumental constructions. Like many roman constructions like the coliseum, the arch of Constantine doesn’t go unnoticed for its use of repurposed material. The use of spolia has many advantages that were very meaningful in the time of the Roman Empire. Recycling older material is a lot more cost effective than…

After the extraction, recrystallization, and determination of melting points for the unknown compound #4 were performed, and observations were noted, the results were obtained. The two compounds yielded were 4-tert-butyl phenol and triphenylamine. The masses obtained of each compound were 0.071g and 0.298g. The melting point ranges obtained are as follows; for the first the solid started to melt at 94 ˚C and was completely melted at 98˚C, and for the second the solid started to melt at 115 ˚C…

Diecast vehicles are made when manufacturers pour molten metals into a steel mold. Afterwards, they get decorated with plastic, rubber, other metal and glass. Before you purchase a diecast vehicle, first decide if you want a modern or vintage Honda diecast. Collectors normally hunt for the vintage pieces while children like the modern diecast models. That, however, is not always the case, and sometimes people collect all forms of diecast models. The diecast vehicles made after 1970 were…

Coliscan easygel nutrient broth was stored in the freezer. Around 24 hours prior to sampling, the broth was moved to the refrigerator to thaw. The sampling procedure follows the procedure stated in the Coliscan Easygel Instructions. When we were ready to begin sampling, the thawed broth was placed into a cooler. We started sampling at Cornerstone pond then move to the Wyoming site, then downtown Grand Rapids, then Plainfield, and then Versluis lake. The procedure for Cornerstone pond and…

Melissa, Belic. Nicholas, Brown. Amy Landis. “Toward zero waste: Composting and recycling for sustainable venue based events.” EBSCOhost Researcher. Waste Management. Apr 2015, Vol. 38, p86-94. 9p. This source evaluates a different waste management strategies, the seven waste management scenarios included traditional ways such as composting and recycling. The waste audits were conducted at four Arizona State University (ASU) baseball games, including a three game series. The authors are well…

municipal solid waste (MSW) a year. Out of the 251 million tons of MSW, 34.5% was recycled and composted. That is equivalent to the average American recycling and composting 1.51 pounds of their daily 4.38 pounds of MSW [1]. Of the 34.5% of MSW that is recycled, which equates to 86 million tons, 65 million tons of MSW was recycled, and 21 million tons was composted. More than half (54%) of the United States’ remaining MSW was sent to landfills, and 29 million (12%) was combusted for energy…
