Sustainable Waste Management
Kristi McKenney, Manager, Aviation Planning and Development, Port of Oakland
ACI Colloquium, CairoNovember 2008
OAK Overview
• Airline passenger facilities– Two terminals: 29 aircraft gates– 9,000 on-Airport parking spaces (Hourly, Daily, Economy, and Valet parking)
• Air cargo sort facilities– FedEx– DHL– United Parcel Service
• General aviation facilities– 2 Executive terminals
• KaiserAir• Business Jet Center
– Flight schools– Aviation High School– Hangars
Sustainable Waste Management
• Waste sources associated with airports
• Why manage waste
• Key Stakeholders
• Program Development and Management
Airport Sources
• Construction waste often greatest total volume
• Airline deplaned waste often greatest operating volume
• Concession waste, food waste
• Waste water
• Office waste
• Facility maintenance and cleaning waste
Why Waste Management
• Waste consumes resources
• Waste is expensive
• Waste can be a resource
• Waste brings significant health and environment issues
Key Stakeholders
• Government Regulations
• Airport Organization
• Service Providers/Tenants
• Airlines
• Waste Companies
• Community
• Construction Industry
Program Development and Management
• Staffing Resources (1/2 staff position)
• Collaboration – Service Providers, Tenants, Airlines (Increasing Interest: KLM, Delta)
• Understand behavior drivers
• Understand economics/regulations (California State – 50% reduction from 1989 )
Program Development and Management
• Target Setting
• Measurement
• Monitor behavior patterns
• Program revision based on feedback
Program Development at OAK
• Begin with office sources– Recycling paper, bottles, cans
– Setting printers to double sided
– Using electronic storage, data management
• Advance to terminal sources– Provide receptacles for customers
– Work with cleaning and maintenance staff
– Work with concessions for supply waste and reducing waste, composting of food waste

Program Development at OAK
• Reuse Facilities to the extent feasible
• Implement Materials Management Program
• Beginning to work more extensively with airlines
Reused Facilities
Reused Facilities•
Combining New and Reused
Materials Management Issues(Not Just About the Environment)
• Repeated Unauthorized Disposal of Construction Waste on Airfield and Airport Properties
• Potential Wetlands Compliance Issues
• Escalating Project Budgets for the Disposal of Concrete, Asphalt and Soil
• Project Overruns Due to Large Soil Disposal Contingencies
• Shrinking Supply and Increasing Costs to Import Aggregates for New Construction
• No Centralized Materials Management Protocol
Materials Program Development
• Formed an Interdisciplinary Working Group:– Airport Management
– Engineering Design
– Environmental Planning
– Finance
• Defined Airport Material Needs
• Developed a Centrally Managed and Coordinated MMP
Business Planning
• Prepared Materials Management Business Plan
– Calculated Material Disposal and Import Costs/Benefits with MMP vs. without MMP
– Defined Resource Requirements
– Developed Operating Budget
– Determined Optimal Management Model• Contractor vs. Port, charging fees approach,
centralized management
Materials Management
Asphalt Grindings
from Taxiway
Demolition
Stockpiled at
D-5 Site
Crushing Operations
Innovation – Cost Reimbursement
• Benefiting Projects are Invoiced for Materials Reused– Material Unit Cost Calculated by MMP Work
Order Accruals
Material Stockpiles at 65-Acre Site
East Apron Phase 1 Project
Results – CIP Funded Start-Up Costs
Investment in Setting Up the MMP = $681,831
$469,960
$143,316$68,555
Develop Project Manual and Contract for On Call Crushing (WO 107008)
MMP Business Planning, D-5 & 65-Acre Site Preparation and Program Development (WO 106990)
MMP Project Planning & Entitlements (WO 106878)
Results 2004 – 2007
• 11 Projects have Disposed of 420,000 Tons of Concrete, Asphalt and Soil
• $4.9M in Disposal Savings at OAK
Apron Rehabilitation Project Stockpiled Asphalt, Concrete and Soil Blended to Create P-209
Results Reuse Activity 2004-2007
• Over 130,000 Tons of Concrete, Asphalt and Soil Crushed, Blended to FAA Specified P-209 and P-154 Aggregates, and Reused on the Airfield
• Over $1M in Material Import Savings at OAK
Conveyors Moving P-209 as its Crushed
Newly Crushed P-209 Conveyed and Stockpiled for Reuse
MMP Operations 2008-2010
• Continued Support for Airport and Tenant Construction Projects
• Expanded Services to off airport users• Production of Other Types of Material??
– Pre-cast Piles– Concrete for Curb
and Sidewalk
FAA Spec P-209 Ready for Reuse
