The Environmental Benefits of Roseville's Recycling Program in 2006 To better understand the environnlcntal benefits of recycling, it can be helpful to translate the number of tons recycled into the number of trees replaced by recycled paper, energy savings, the equivalent greenhouse gas reduction, water conservation, ete. Several environnlcntal calculators have been created to attempt to translate recycling tons into energy savings or greenhouse gas cm.issions reduction. The equations used in these calculations try to take into account the "full life cycle" of each material.. _ everything fi-Olll off-setting the denland for 1110re virgin materials (tree harvesting, 111ining, ere.) to preventing the pollution that would have occurred if that material Vlcre disposed of (landtllled or incinerated). Different calculators may include some or all of the many factors that contribute to the "full life cycle," so results fi'om calculator to calculator will vary. The EnviroI1l11ental Protection Agency (EP A) created an environll1ental calculator as part of its study of waste lllanagenlent practices as they relate to greenhouse gas errussions. This calculator is conul1011ly used in the recycling industry. (http://epa.gov / climatechange/vrycd/waste/ calculators/W al111_Form.html) There are several online sources that you can use to can further translate the greenhouse gas ell1issions reduction and energy savings into everyday activities (such as cars off the road or number of trees saved). Again, different calculators will yield different results depending on their assunlptions and equations. According to the EPA calculator, Roseville's 2006 recycling efforts resulted in the following enviromnental benefits: 8537 metric tons (MTCE) (MTC02E). MTCE (Metric tom of carbon equivalent), MTC02E (Metric tom of carbon dioxide emissions) are figures commonly used when discussing greenhouse gas emissions. 3,441.21 Tons For more infonl1ation, visit: http:// epa.gov / climatechange/wycd/waste/ measuregbg.html#cbck Use of Biodiesel in Recycling Trucks in Roseville In addition to the tlgures noted above, Eureka Itecyding runs their tlucks in l~osevilJe on a 20% biodiesel blend, which further reduces greenhouse gas enlissions.
