Miami-Dade CountyA History of Environmental Leadership 2000 - Adopt-a-Tree Program = over 184,300 trees 2002 Began Purchasing hybrid vehicles – Currently have 524

electric/gasoline 2007 - Miami-Dade County established a Sustainable Buildings

Program (SBP) for County facilities 2009 - Creation of Office of Sustainability to track climate change,

energy efficiency, smart transportation and solid waste initiatives. 2009 – MDT began operating

Hybrid buses. Currently have 43diesel/electric buses

First in the State to have an enforceable vehicle emissions program .

CONT’D

Water Conservation Programs – over 30 million gallons per day saved since 2007

Single-Stream Recycling Program - 2x amount since 2008; Approximately 1.2 million tons of waste processed annually. 240,000 tons of materials being processed into Biomass

The energy generated from the County’s waste to energy plant is enough to supply the electrical needs of 90,000 homesin MDC

NEW FLEET

Quantity - 15 Refuse Haulers Equipment class - 33,001-60,000 lbs.Model year - 2011 Year of replacement - 2011 Fuel Type – ULSD (15ppm) Fuel volume – 47,730 Vehicle miles travelled – 9,000 Idling hours - 200

The Technology

Average expected life of the vehicles is seven (7) years Uses an advanced hydro-mechanical series drive

system; designed to significantly reduce fuel consumption & increase productivity

Brake to energy recovery technology Hydro-mechanical series drive system uses hydraulic

pressure to get from house-to-house Once vehicle exceeds 40mph, it will automatically

begin using diesel fuel while the hydraulic tanks regenerate.

AUTOMATED HYBRID HYDRAULIC REFUSE VEHICLE PROJECT

Total Project Cost: $5,250,000 Voluntary Cost Share: $3,750,000

Description: Fifteen (15) 2002 Peterbilt Packers with an approximate tare weight of 35,000lbs were replaced with fifteen (15) new Automated Hydraulic Hybrid Refuse Vehicles.

Trucks will utilize hybrid technology to achieve a 45% reduction in fuel consumption & emissions of PM; Nox; HC and CO2

PROJECT DESCRIPTION

One of the largest government owned & operated waste collection & disposal system in the SE USA

Recycle services to over 320,000 households in unincorporated MDC & nine (9) municipalities

Helps to alleviate environmental impact on the degrading air quality

Targets routes serving neighborhoods with children at risk, elderly residents, others affected by respiratory illnesses, areas with poor air quality.

FAQ How much does it cost? We are targeting an ROI of 3 to 4 years over a

standard truckPerformance? Improved 0-25MPH acceleration when baseline

against different trucks with 350Hp engines and standard automatic transmissions

Fuel Saving? For typical 100 foot start-stop operations the fuel

savings are between 30% and 50% over baseline vehicles
