VALUE ADDED! QUANTIFYING THE AMOUNT OF ENERGY SAVED BY RECYCLING Patricia Higby & Tony Fang 2004

Generally Recognized Benefits of Recycling: 

Generally Recognized Benefits of Recycling Good waste treating method Reduces landfill space Provides materials for industry Additional important benefits of recycling ---

Energy Benefits !: 

Energy Benefits ! Today Energy and Environment are the two most important things in the world. According to our research, recycling can significantly save energy. Not only the energy saved itself, but also many important associated benefits, especially related to the environment. Value Added !

How Can Recycling Save Energy?: 

How Can Recycling Save Energy? Two areas where energy is saved: Industry manufacture process - recycled vs. raw materials Waste treatment - recycling vs. landfill

Sample Life Cycle Analysis: (Aluminum): 

Sample Life Cycle Analysis: (Aluminum) INCOMPLETE CYCLE Mine and ship bauxite to plant; Separate alum from bauxite Make alum sheet Ship alum to can plants Make alum cans Ship alum to bottlers for filling Transport filled cans to retailers for purchase Use cans, then throw away LANDFILL or INCINERATION

Energy Saving Facts: Recycled Materials Manufacture Process -- Plastic Energy Saved: 21.14 Mbtu per ton. Recycling one 2-liter bottle saves enough energy to light a 100 watt bulb for 4 hours!

Energy Saving Facts: Recycled Materials Manufacture Process -- Paper: 

Energy Saving Facts: Recycled Materials Manufacture Process -- Paper Energy saved: 13.00 Mbtu per ton Recycling 5 sheets of paper saves enough energy to light a 100 watt bulb for 1 hour!

Energy Saving Facts: Recycled Materials Manufacture Process -- Glass: 

Energy Saving Facts: Recycled Materials Manufacture Process -- Glass Energy saved: 2.13 Mbtu per ton Recycling one glass bottle saves enough energy to light a 100 watt bulb for 4 hours!

Object of Our Project: 

Object of Our Project Based on this information, we can calculate how much energy has been saved due to recycling in: Cedar Falls State of Iowa Entire USA Is the energy saved significant?

Energy Benefits Calculation Method: 

Energy Benefits Calculation Method Energy Saved from Manufacture Process Recycled Tons  Per ton energy saved Energy Saved from Avoiding Landfill Energy cost of landfill Total Energy Saved = Energy Saved from manufacture process + landfill

Other Environmental Benefits : 

Other Environmental Benefits Production of energy results in emission of green house gases, such as CO2 Reducing energy use also reduces these gases as well as other pollutants.

Conclusion and Summary: 

Conclusion and Summary Recycling saves significant amounts of energy Total energy saved in U.S.A. in 2000 was enough to support all of the households in 7 states like Iowa, or 623 cities like Cedar Falls Total energy saved in Iowa in 1999 was enough to support all of the households in 14 cities like Cedar Falls
