d.). This comes from our homes, schools, hospitals, and businesses (Municipal Solid Waste, n.d.
). How was waste dealt with before industrialization?In Crete in about 1500 BC put their rubbish in large pits and covered it with dirt (dmguion, 2011). In Athens, Greece 500 BC they mandated dumping trash at least a mile out of town (dmguion, 2011). In AD 200, Rome it employed teams of two men to pick up trash from the street and take it “away” to the dump or emptied it into the timber somewhere down stream(dmguion, 2011).Why did this process have to change?This processed of the dumpsites changed because of the diseases it started causing. The piles of trash attracted rats, mice and birds that caused an outbreak of plagueBody of Paper1. Describe an open dump.
What environmental problems do open dumps cause? An open dump is the improper disposal of unwanted items such as household trash, garbage, wastes basically any material that will rust, rot or burn. The problems that open dumping has caused for the environment is when the waste starts to rot, will then start to smell or create methane gas that also contributes greenhouse effects. 2.
Describe an early landfill, and how these differ from open dumps. What problems are associated with early landfills? This should include a discussion of leachate, methane, incomplete decomposition, and settling. Early landfill took the place of open dumps with no effort to cover or compact the waste.
Early landfills burned the trash and the materials decomposed faster. Landfills use clay or plastic lining to catch the leachate. As organic waste decomposes it generates gases, including methane which is a greenhouse gas. (The Environmental Literacy council, n.
d.). 3. Describe a modern landfill.
What are the differences as compared to early landfills?Modern Landfills use heavy machinery to compact waste (dmguion, 2011). That makes t take less room in the dump (dmguion, 2011). It also cuts down on foul odors (dmguion, 2011). A landfill isolates trash from the surrounding air, earth, and bodies of water (dmguion, 2011). A landfill must have a liner two different kinds called the Clay liner or a Synthetic plastic liner to contain leachate. A landfill takes cares of problems of odor, vermin and pollution ((dmguion, 2011).
). 4. Choose 1 of the following landfills, and explain the innovations being implemented to make the landfill more productive and to reduce its environmental impact: I chose to write about Mariannhill Landfill, South Africa this landfall has technology that ties together waste management, recycling and biodiversity. This is called the closed loop system they provide treatment for leachate, and electricity from degassed methane helping to realize South Africa’s emission. Reductions waste that can not be reused or recovered for alternative use is landfilled compacted into cells lined with material to prevent leakage to the surrounding environment once a cell is full it is covered and rehabilitated with indigenous plants which later is saved and used to restore surrounding land.
The landfill ow the MLC has combined renewable energy technology with combating climate change and the realization of carbon-based emission reductions ConclusionI have learned that when disposing trash we have to be mindful of where it goes and how to prevent waste and pollution. We have to care enough to keep the earth clean because if not we are harming ourselves. This is one of the moments that “it takes a village” and everybody has to do their part in making it a better world that we can live and survive in.
