The Case of Climate Change
Recycling Can… Save energy
Reduce greenhouse gas emissions
Decrease human impact on Global Warming

Recycling Saves Energy
New products made from recycled aluminum use 95% less energy
Recycled steel products use 75% less energy
Less energy fewer fossil fuels burned reduction of CO2
(greenhouse gas) emissions into the atmosphere

Recycling Reduces Greenhouse Gases
Greenhouse gases, primarily carbon dioxide (CO2) and methane, are gases that trap heat in the atmosphere
Energy-related activities account for the majority of CO2 emissions
Landfills account for the largest human-made contribution to methane emissions, a gas 72 times more potent than CO2 over 20 years
Composting is the best method to reduce methane buildup in landfills, allowing aerobic conditions to break down organic waste without producing methane

Why Now?
Do not wait until the potential effects are irreversible
Negative effects can be: Migration of insect and animal species, potentially introducing new diseases Extinction or change of species and ecosystems Sea level rise – loss of wildlife, islands, beaches; dangers of flooding and storm
surges More extreme weather conditions Droughts and heat waves, effecting water supply
and crops Poorer air quality
Limiting waste production can limit individual contribution to climate change

Methane, a greenhouse gas, is 20 times more potent than CO2, over a one hundred year period and 72 times more potent in a 20 year period.
Responsible for almost a quarter of man-made global warming.
For the first time in a decade, scientists reported dramatic increases in levels of methane. ~ Sources for methane gas: animal waste, organic/ food waste….

Organics & Methane Organic (Food) Residuals
Issues: NC generates 800,000 tons
food residuals per year
Sanitary issues: vermin, odor, smell, liquid…
Methane gas related to food scraps
High cost of CO2 generation related to pickup, transfer and to landfills.

Other DPPEA GHG webinars for facilities
May 18, 10:00 a.m. - 12:00 p.m. - GHG Reduction Projects at N.C. Facilities - Successes and Lessons Learned ESI members will present on projects implemented at N.C. facilities to reduce greenhouse gas emissions, including Eaton, and EMC2 and Novozymes NA. http://www.surveymonkey.com/s/WY8HMM6
June (date TBD) - Energy Management - A Pathway to GHG Reduction Saving energy can help to reduce indirect greenhouse gas emissions. Energy management systems are one important tool to help you manage your energy savings. Not sure how to pay for your energy reduction projects? Performance contracting can help you install now and pay through the resulting savings over time. Also, N.C. utility companies will discuss current incentive programs to help facilities implement energy saving projects now.
