Waste Management Innovation, Sustainability and Customer Value 2013 Tennessee Symposium: Growing Tennessee ’ s Recycling Economy August 15, 2013 Jessica Preston, ATAK Market Area Sustainability Program Director
Company Overview
Transformational Change Not just a push – pack – cover company! Ø Know Our Customers Better than Anyone Else Ø Extract More Value from the Waste Stream Ø Innovate and Optimize our Operations
Transformational Goals by 2020 Focus on management of existing resources Ø More than double our recyclables volume to 20 million tons per year Ø Improve fuel efficiency and reduce emissions of our fleet by 15% Ø Double the amount of green energy produced from waste to power more than two million homes Ø Quadruple our wildlife habitat sites to 100 certified sites (in 2008, 49 Wildlife Habitat Council certified sites)
Transformational Goals by 2020 Goals and Drivers § Corporate Goal - More than double our recyclables volume to 20 million tons per year § Meet customer needs § Increase revenues/market share § Airspace savings: • extend life of landfills § Soil poor sites: • expensive to operate Ø Value inherent to materials
Waste Management Green vs. Traditional Services 2007 – 2011 saw marked shift away from traditional landfilling, with increases in recycling, green collection and transfer, and energy production. Figure from: December 2012 WM Sustainability Report
Wide Variety of Materials are in MSW Opportunities abound: Paper Plastics Metal Food Wastes Yard trimmings/Wood Figure from: Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2011
Wide Variety of Materials for Recovery Even with a 34.7% total recycling rate significant volumes remain remain Plastics Paper/fiber Metal Food Wastes Yard trimmings/Wood Figure from: Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2011
Recovery: Only Part of the Equation Economic “ Headwinds ” to recycling exist Landfill Bans • Ineffective without companion legislation encouraging purchase of products containing recycled material • Markets need to be supported through legislation Operation Green Fence • China ’ s 2013 enforcement of existing laws concerning random inspections of incoming commodities • Increases domestic supply of commodities with associated price drop § Increased cost of business, lowers rebates § Positive benefits of keeping it domestic do exist
Focus on Sustainable Growth Tennessee Initiatives Think Globally… Act Locally
Focus on Sustainable Growth Innovation, Optimization, and Customer Focus Middle Tennessee EcoPark MTEC Material Recovery at Working Face Landfill Mining Future Organics MRFs – Recent Acquisitions River Hills River Gate Other Material Recovery Programs New Consumer Services/Products
“ Middle Tennessee EcoPark ” MTEC (C&D Recycling Facility) Material Recovery at the Working Face Future Organics Solution Landfill Mining
Middle Tennessee Environmental Center Construction Demolition Recycling In 2012, the Middle Tennessee Environmental Center moved • adjacent to the Southern Services Landfill Improved efficiencies and outlets for materials • OCC, wood, aggregate, metals • Metro-Davidson County, + • surrounding areas 2012 - 90,000 cu yds • Recycled > 50,000 cu yds •
Middle Tennessee Environmental Center Trucks arrive to check station • Most loads go to landfill • C&D Recycling at work face • Communication with operators • LEED jobs go to MTEC • (extra reporting, tracking)
Middle Tennessee Environmental Center After entering MTEC… • Load is dumped out on tipping floor, photographed, inspected, documented • Trained, experienced personnel – in field and in ops support
Middle Tennessee Environmental Center Sorted with skid steer, excavator with grapple, loader Final hand sort (metals, wood, OCC) • Metals separation - Night operator at working face goes through more loads with magnet Placed in boxes for haul to grinder, metal processor, MRF , or up to landfill (residual) Data communicated to customer (DART) and internally
Material Salvage at the Working Face Initiated in 2008 and permitted through TDSWM § Removal of metals, cardboard, useable aggregate In 2012-2013, salvaging OCC and additional types of metal with new equipment 2012 results • OCC, ferrous and non-ferrous metals • ~1100 tons extracted
Landfill Mining • Intent is to remove metals and other recoverable materials • Gain airspace and retrieve valuable commodities • Pilot study in Alabama - Fultondale Construction & Demolition Landfill • Careful, methodological approach • In 2012 - Worked with TDEC to obtain appropriate permits
Landfill Mining 2013 – utilized three shallow geophysical techniques to identify “ hot spots ” in 2 ac study area. Weather permitting, will excavate this fall.
Organics Recycling • WM estimates that 30-35 million tons are organic in nature from the materials we manage (excluding recycled paper, OCC, etc). • WM currently manages over 1.25 million tons of organics to beneficial uses including composting, mulch operations • WM currently operates 36 Organics Facilities
Organics Recycling In Middle Tennessee – exploring range of options • Composting • Anaerobic codigestion • Economics are not there yet for WM Exploring partnerships with other vendors, municipalities
Material Recovery Facilities Enhancing Recycling Capacity
River Hills MRF Single Stream and Source Separated Inbound volume of approximately 4000 tons/ month Of this, approximately 68% is single stream • 60% residential • 40% commercial Majority is OCC in the remaining volume Single shift One baler Sort line with various sorting mechanisms Q4 2013-Q1 2014: Installation of container line to separate containers – tin, aluminum, plastics (HDPE from PETE)
River Gate MRF Primarily Fiber Inbound volume of approximately 2700 tons/ month - nearly 100% commercial volume, very little residential Of this volume: • 43% OCC • 24% office paper • 13% boxboard • 4% misc paper grades • 7.5% glass • 4% combined plastics (film) • 3.5% other non fiber Single shift Two balers Metro Convenience Center is Co-Located
Material Recovery Facilities Enhancing Recycling Capacity We still have capacity and plan to grow. These MRFs can support local communities • Need less capital in municipalities/counties • Build on existing hub-and-spoke models • Less exposure (for communities) to risks of volatile commodities markets. Examples – • Lewisburg-Marshall County • Spring Hill • Metro Davidson County
Other Material Recovery Operations
Fiber Mining Removal of OCC “ Rough Sort ” • Nashville – Antioch Transfer Station • Temporarily suspended due to operational limitations on space – anticipated to begin again in Q4 2013 • Memphis Transfer Station • Successfully mines >300 tons OCC/ month
Landfill Gas-to-Energy Tennessee West Camden Sanitary Landfill • Three Caterpillar 3520 Engines • Generates 4.8 MW • Enough to power 4800 homes Chestnut Ridge Landfill • Four Existing Caterpillar 3516 Engines • Added One Caterpillar 3520 Engine • Generates 4.8 MW • Enough to power 4800 homes Power for the future • Gas curve to continue 40+ years • Expanded capacity
New Consumer Products
The “ Greening of America ”
Think Green from Home Through mail-back programs, WM allows customers to recycle fluorescent lights, batteries and CFLs without ever leaving their home.
Solar Compactors • Ideal for busy public areas (downtown, parks, malls) • Even works with indirect sunlight • Low collection costs because they hold up to 5 times the volume of waste • Cities can use side panels as billboards to promote local programs • Franklin, Tennessee • Nashville Greenways
