–
1952
Rivers And Harbors Act Of 1899 –
Prohibited Dumping Of Large Objects Into Navigable Waterways, Lead To Decline Of People
Dumping Msw Into Water Bodies
Clean Air Act Of 1970 –
Stopped Open Burning Of Msw As Well As Closed Uncontrollable Incinerators Because Of Their
Health Risk To Humans (Respiratory Tract)
Resource Conservation And Recover Act Of 1976 (Rcra) –
Set Guidelines For The Disposal Of Hazardous And Non-Hazardous Waste; Subtitle D Also Set
Guidelines For The Design And Operation Of Landfills
Explain The Difference Between Planned And Unplanned Reuse And What These Scenarios
Entail For Amazon's Shipping Boxes. Explain How Amazon And The Consumer Have To
Change Their Habits. –
Planned Reuse: Steps Have Been Taken To Design The Product Where It Is Easy/Convenient To
Reuse The Product For Its Intended Purpose
Unplanned Reuse: Using The Product In An Alternate Way From Its Intended Purpose, Not
Efficient (Wasted Resource)
Amazon Could Make Their Shipping Containers Sturdier And Talk To Postal Offices About
Size/Weight Limits, Having An Agreement To Let The Consumer Reuse The Shipping
Container At Various Post Offices. The Consumer In Turn Would Have To Agree To Reuse The
Product And Not Just Dispose Of It After Arrival.
Europium Is A Rare Earth Element, Name A Common Device That Contains This Rare Earth
Element. –
Televisions
Explain Briefly Why Sampling Procedure And Sample Size Are Important In Characterizing Msw. –
, There Are Two Methods To Determine Composition Of Msw: Input Method & Output Method.
Input Method: Looks At Published Data From Studies
Output Method: Uses Samples From Studies To Determine Composition Of Msw
Msw Is Very Heterogenous, And You Want Broader Trends About Its Characteristics To
Develop An Outline For The Quartering Or Coning Process.
Which Of The Following Is Not A Specification Included In Proximate Analysis Of Msw? -
A.) Moisture Content
B.) Hydrogen Content
C.) Volatile Matter Content
D.) Noncombustible Content
Answer: Hydrogen Content
In 2 Paragraphs, Explain Why Glass Recycling Has Seen A Recent Decline In The Us And Why
Is Production Of Glass Bottles From New Raw Material More Economic Than Used Glass? –
Glass Recycling Has Decreased In The Us Primarily Because Of Its Weight. Unlike Europe,
Recycling And Material Recovery Facilities Are Generally Further Away, So It Is Expensive To
Transport The Glass To These Recycling Facilities, Instead Of Just Hauling It To A Landfill
That Is Closer.
It Is More Economic To Just Create New Glass Bottles Because In The Us, Most Recycling
Centers Are Single-Stream Recycling. This Causes The Glass Containers To Become
Contaminated/Impure, So It Costs Money To Separate Them And Clean Them For Reuse,
Whenever Landfilling The Glass Is Much Cheaper. In Addition, The Mining Companies Have
Streamlined Their Process Of Extracting Silica, And Because They Are A Larger Business,
They Can Afford To Sell It At A Lower Cost. Therefore, Glass Companies Are More Likely To
Buy Cheaper Raw Material From A Reliable Source Than Glass From A Recycling Center That
Is More Expensive.
What Is The Largest Component Of Msw Collection Cost? - A.) Human Labor
B.) Landfill Tipping Fees
C.) Fuel
D.) None Of The Above
Answer: Human Labor
Describe What Happens At A Transfer Station And How Can Msw Collection Be More Efficient
Here? –
A Transfer Station Is Where Smaller Refuse Collecting Trucks Drop-Off/Dump Their Load That
They Collected At A More Centralized Area. This Waste Is Then Loaded Onto Larger
