ROCKY DIRICO, DEPUTY COMMISSIONER AT DSNY
Besides leading the way to zero waste, DSNY
has another crucial task – keeping the city’s
streets and highways clear of snow and ice.
Whenever a heavy snowfall hits the city, the
Department of Sanitation works around the clock
to make sure that streets are clear for emergency
vehicles, along major roadways and around
hospitals, schools and fire and police stations.
THE DIVERSITY OF tasks and environments
and the tough working conditions mean that
demands are high on the vehicles used in the
DSNY has a fleet of 5,800 different vehicles,
from support vehicles and mechanical street
sweepers to sand/salt spreaders and collection
trucks. When it comes to heavy vehicles like
refuse and recycling trucks, the majority are
Mack trucks. DSNY and Mack Trucks have been
working together for more than 30 years and
collaborate closely on all levels. Most of the
Mack trucks are customised to meet the needs of
As owner to the largest fleet of heavy-duty
vehicles in New York City, the Department of
Sanitation plays a very important role when it
comes to testing new technologies and solutions.
“If we don’t lead, no one else will. I’m very
proud of who we are and what we have done.
Everyone looks to us for guidance and follows
our lead,” says Rocky DiRico.
A lot of effort is put into finding new solutions
that will make the vehicles more fuel efficient
and sustainable. The Mayor of New York City,
Bill de Blasio, has declared that greenhouse gas
emissions should be reduced by 80 per cent by
DSNY HAS LONG worked hard to reduce
greenhouse gas emissions. It has its own
laboratory where it measures emissions and
constantly tests alternative fuels like biodiesel
and dimethyl ether (DME). In its fleet, it also
runs about 50 hybrid refuse trucks and a handful
of hybrid electric trucks.
“We work very closely with Mack Trucks to
identify different technologies that can help
us reach our goal of reducing greenhouse gas
emissions. Because of the size of the fleet and
multitude of vehicles that we have, we don’t
think there will be a single solution. It’s also very
important for us to see the return on investment;
any technology that we identify has to enable us
to maintain the productivity of the fleet,” says
Spiro Kattan, Deputy Director of Clean Fuels and
Technology Division at DSNY.
Most of the refuse and recycling trucks on the streets of New York are Mack trucks,
customised to meet the needs of the 59 different districts.
