Sustainable Land Use
Clear Creek Riparian Restoration Project utilizes goats for riparian restoration. The goats consume over 90% of the non-native vegetation and weeds.
Dining service waste is fed to over 30,000 red wiggler worms, and worm castings are then used to fertilize our growing fields.
Biofiltration Wetland Education Learning Laboratory (BeWELL) Project offers students in Mathematics, Engineering, and Science Achievement (MESA) an opportunity to work as interns on a real-world project by monitoring campus storm water runoff, and calculating the results necessary to biofilter the chemicals.

Wildlife Refuge offers “live” classroom settings that further student learning.
Agriculture Department has obtained organic certification on 26 acres where fruit, lettuce, hay, and wine grapes are grown.
Sustainable Land Use
PRESENTATION FOR:
CCFC 2011 | Butte College: A Grid Positive Lab for the Next Generation
Operate an extensive program recycling paper, cans, bottles, scrap metal, hazardous waste, and much more.
Dining Services composts 1,500 pounds of food waste each month, and recycled or recyclable materials are used for napkins, plates, food containers, and more.
Meets the state standard to divert 50% of waste stream from the landfill, and recycles between 75-93% of waste each year.
Recycling
PRESENTATION FOR:

Transportation Largest California
Community College bus program keeps 1,500 cars off road daily
Buses are biodiesel compatible, several use natural gas
Preferred parking for carpool, alternative fuel, hybrid, and fuel efficient vehicles
Planning with county to add bike lane to campus

Lessons Learned
Set goals: Grid-Positive by 2012 Carbon Neutral by 2015
Track the changes that impact you (ex: utility rates, rebates)
Know what you have to work with (budget & energy use) Don’t be shy – let the ESCOs know what you want Degradation of production is a reality, funding residual
consumption may be necessary Implement energy saving measures first…reduction is
cheaper than production!
