Front Loader Garbage Truck & Dumpster Bins I CSU Math Center | 1-800-977-8449 x6538 | teamsucceed@columbiasouthern.edu Math Center Requests: Math Center Request Form Problem: A front loader garbage truck of 25 yd3 collects municipal solid waste (MSW) each week from dumpster bins of apartment complexes located throughout the city. The waste in the truck is compacted to 500 lbs./yd3. The uncompacted waste in the dumpster bin is 150 lbs./yd3. (a) How many full dumpster bins with a 1.75 yd3 capacity can be placed into the garbage truck? (b) If the apartment complex has a mandatory recycling program and each person places only 2.5 lbs. per day of trash into the dumpster bin, how many more people can the garbage truck serve before it is full? (c) If the apartment complex has a mandatory recycling program and each person places only 1.5 lbs. per day of trash into the dumpster bin, how many more people can the garbage truck serve before it is full? Solution: (a) How many full dumpster bins can be placed into the garbage truck? Let's first calculate how many pounds of MSW can be filled in the garbage truck: The volume (v) = 25 yd3 (cubic yards) and is the particle density, which is mass/volume-therefore = 500 lb. yd3 Lbs. of MSW in garbage truck = 25 yd3 x 500 lb. = 12,500 lbs. in garbage truck yd3 Next, we calculate how many pounds of MSW in the dumpster bin: v = 1.75 yd3 and = 150 lb. yd3 Lbs. of MSW in dumpster bun = 1.75 yd3 x 150 lb. = 262.5 lbs. in dumpster bin yd3 Finally, we can calculate the number of dumpster bins of MSW can fit in the garbage truck: No. of dumpsters = 12,500 lbs. x garbage truck 1 dumpster bin = 47.62 dumpsters per garbage truck 262.5 lbs. (b) How many more people can the garbage truck serve before it is full? (based on 2.5 lbs./day) First, calculate the number of pounds per week: 2.5 lbs. day x 7days = 17.5 lbs./week week Next, calculate the number of people using each dumpster: 262.5 lbs. per garbage truck per week = 15 people per dumpster 17.5 lbs. per week per person Finally, calculate the number of people served: 15 people dumpster x 47 dumpsters = 705 people (c) How many more people can the garbage truck serve before it is full? (based on 1.5 lbs./day) First, calculate the number of pounds per week: 1.5 lbs. day x 7days = 10.5 lbs./week week Next, calculate the number of people using each dumpster: 262.5 lbs. per garbage truck per week = 25 people per dumpster 10.5 lbs. per week per person Finally, calculate the number of people served: 25 people dumpster x 47 dumpsters = 1,175 people Therefore, the number of additional people: 1,175 705 people = 470 additional people served \fMEE 5901, Advanced Solid Waste Management Unit I Assignment This assignment will allow you to demonstrate the following objectives: Assess the fundamental science and engineering principles of solid waste management.

What science and engineering principles are involved in this program? (Your total response for all parts of this question should be at least 300 words.) 2. A) Establish a recycling team: When setting out to develop a community recycling program, there are many components to be considered. From markets to collection bins, equipment to outreach, a strong hauler contract to budgets, it can get overwhelming. A recycling team, or steering committee, may be what your community needs to remain organized. A recycling team is tasked with the coordination of all recycling . A recycling coordinator for the program should be responsible for keeping the eventual goals of the program in mind and ensure that the recycling program is running as efficiently as possible. In the case of larger communities, a team of organizers may be necessary to keep recycling initiatives on track. B) Determine Scope and Assess Your Waste: Generally, starting and then expanding your program once the basic components are in place is the best approach to starting from scratch. Trying to do too much at once becomes overwhelming quickly and prevents sufficiency. Start by determining the scope of your recycling program and keep the scope as focused as possible. You can always expand the scope once you have mastered the basic tiers. It is important to know what type of potential recyclables your community generates and which ones are generated the most. To do this, it may be helpful to conduct a waste assessment in your community. Records examinations, touring the community, and waste studies are three common approaches to conducting a waste assessment. Your assessment might require just one of these activities or a combination of approaches. The recycling team should determine which assessment is best for your community based on factors such as complexity of the waste stream, resources (money, time, labor, equipment) available to implement the waste reduction program, and scope of your waste reduction program. C) Evaluate Options and Set Reduction Goals: After conducting a waste assessment, use the information to list, analyze, and choose appropriate waste reduction activities for your community. Consider holding a brainstorming session to identify potential waste prevention and recycling activities. List your most promising options and evaluate them in terms of your program's economic and operational limitation. When analyzing and selecting specific options, focus first on waste prevention, which will enable your community or municipal facilities to eliminate waste at the source. Communities can support business waste reduction and recycling by encouraging partnership in EPA's WaterWise. This free, voluntary program through which organizations eliminate costly municipal costly municipal solid waste and select industrial wastes, benefits their bottom line, the environment, and can gain recognition for your community. WasteWise is a flexible program that allows partners to design their own waste reduction programs tailored to their needs. Next, evaluate recycling options to better manage waste that cannot be prevented, Before collecting recyclable materials, be sure to identify markets for them. Finally, examine opportunities to buy or manufacture recycled content products. 3. Copper can be found in many kinds of food, in drinking water and in air. Because of that we absorb eminent quantities of copper each day by eating, drinking and breathing. The absorption of copper is necessary, because copper is a trace element that is essential for human health. Although humans can handle proportionally large concentrations of copper, too much copper can still cause eminent health problems. Copper concentrations in air are usually quite low, so that exposure to copper through breathing is negligible. But people that live near smelters that process copper ore into metal, do experience this kind of exposure. People that live in houses that still have copper plumbing are exposed to higher levels of copper that most people, because copper is released into their drinking water through corrosion of pipes. Occupational exposure to copper often occurs. In the working environment, copper contagion can lead to a flu-like condition known as metal fever. This condition will pass after two days and is caused by over sensitivity. Long-term exposure to copper can cause irritation of the nose, mouth and eyes and it causes headaches, stomachaches, dizziness, vomiting and diarrhea. Intentionally high uptakes of copper may cause liver and kidney damage and even death. Whether copper is carcinogenic has not been determined yet. When copper ends up in soil it strongly attaches to organic matter and minerals. As a result it does not travel very far after release and it hardly ever enters groundwater. In surface water copper can travel great distances, either suspended on sludge particles or as free ions. Copper does not break down in the environment and because of that it can accumulate in plants and animals when it is found in soils. On copper-rich soils only a limited number of plants has a chance of survival. That is why there is not much plant diversity near copper-disposing factories. Due to the effects upon plants copper is a serious threat to the productions of farmlands. Copper can seriously influence the proceedings of certain farmlands, depending upon the acidity of the soil and the presence of organic matter. Despite of this, copper-containing manures are still applied. Copper can interrupt the activity in soils, as it negatively influences the activity of microorganisms and earthworms. The decomposition of organic matter may seriously slow down because of this. Industrial exposure to copper fumes, dusts, or mists may result in metal fume fever with atrophic changes in nasal mucous membranes. Chronic copper poisoning results in Wilson's Disease, characterized by a hepatic cirrhosis, brain damage, demyelization, renal disease, and copper deposition in the cornea. 4. Integrated solid waste management refers to the strategic approach to sustainable management of solid wastes covering all sources and all aspects, covering generation, segregation, transfer, sorting, treatment, recovery and disposal in an integrated manner, with an emphasis on maximizing resource use efficiency. The elements are: a) Baseline data on waste characterization and quantification with future and baseline data on prevailing waste management systems and gaps. b) A list of targets to be achieved through the ISWM System c) A plan with details of the Management System covering policies, technologies (and voluntary measures) d) Implementing Aspects such as time schedules, costs, institutional requirements etc. e) Monitoring and feedback mechanism. There are six functional of the waste management system as outlined below: a) Waste generation refers to activities involved in identifying materials which are no longer usable and are either gathered for systematic disposal or thrown away. b) Onsite handling, storage, and processing are the activities at the point of waste generation which facilitate easier collection. c) Waste collection, a crucial phase of waste management, includes activities such as placing waste collection bins, collecting waste from those bins and accumulating trash in the location where the collection vehicles are emptied. Although the collection phase involves transportation, this is typically not the main stage of waste transportation. d) Waste transfer and transport are the activities involved in moving waste from the local waste collection locations to the regional waste disposal site in large waste transport vehicles. e) Waste processing and recovery refer to the facilities, equipment, and techniques employed both to recover reusable or recyclable materials from the waste stream and to improve the effectiveness of other functional elements of waste management. It is the final stage of waste management. It involves the activities aimed at the systematic disposal of waste materials in locations such as landfills or waste-to-energy facilities. This last element has the greatest potential to impact the success of the program, because processing and conversion to useful form is what matters at once
