Integrated Infrastructure
The Center for Sustainable Infrastructure is pioneering a sustainable, prosperous future where we all win.
OUR STRATEGY
We catalyze integrated infrastructure projects in the Pacific Northwest
Traditional infrastructure is designed and operated in silos to serve very specific needs by focusing narrowly on one purpose. CSI promotes strategies that integrate energy, water, and material systems to get the most economic and environmental value for the community.
OUR FOCUS
Industrial symbiosis – where integrated infrastructure meets local economic development
Industrial symbiosis (IS) is a particularly powerful form of integrated infrastructure that optimizes the use of heat, water, organics, and other resources to create economic value and eliminate environmental harm. CSI is leading the charge to harness this model to build showcase projects in the PNW.
Request for Qualifications:
CSI is seeking to partner with firms that provide professional services to support industrial symbiosis efforts in the pacific northwest (Washington and Oregon).
Join us at the inaugural PNW IS Conference this summer!
