   ENVIRONMENTAL SOLUTIONS WORLDWIDE, INC: THERMACAT(TM) ACTIVE LEVEL III PLUS
        CATALYST SYSTEM PASSES FIRST CALIFORNIA HIGHWAY PATROL INSPECTION
                              FOR SCHOOL BUS USAGE

Concord, ON.--(BUSINESS WIRE) - June 1, 2009. Environmental Solutions Worldwide
Inc. (OTCBB: ESWW) (Frankfurt Stock Exchange FWB: EOW) announced today that its
wholly owned subsidiary ESW Canada Inc. (ESWC) received notification from the
California Highway Patrol (CHP) that the Company's ThermaCat(TM) Active Level
III Plus catalyst system has passed the first inspection for usage on school
buses carrying children on California roads.

CHP inspected the ThermaCat(TM) installation on the First Student school bus
located in the Los Angeles Area. Westrux is ESWC's distributor and certified
ThermaCat(TM) installation facility as well as Los Angles California's largest
Navistar, International Truck and Engine dealer with six strategic locations.
First Student, one of Westrux fleet customers, is the largest school bus
operator in the United States and Canada with a fleet of more than 60,000 buses
in service.

With the success of this CHP inspected and approved installation, the
ThermaCat(TM) has become the first fully compliant Federal Motor Vehicle Safety
Standards 301 (FMVSS 301) retrofit Level III Plus diesel emissions reduction
device utilizing a diesel fuel based real-time active regeneration technology to
legally be installed on a school bus operating in the State of California. The
complete ThermaCat(TM) retrofit kit is engineered and manufactured for
installation on each model and year of school bus without alterations to the
frame/chassis or compromising its safety.

In January of 2009 ESWC became the first Company to successfully meet the
applicable FMVSS 301 (crash test) for school buses at a recognized third party
testing facility in Wisconsin. At the conclusion of the test, although the bus
was deemed a total loss, the ThermaCat(TM) passed the crash protocol with a zero
failure rate. In a separate test procedure at the same facility, the
ThermaCat(TM) Active Level III Plus catalyst system and school bus installation
kit were tested on a 1000 hour 100,000 mile vibration and shock durability
simulation machine. Again, the system passed the test protocol with zero failure
to the system or installation components.

ESWC is currently awaiting full verification from the California Air Resources
Board (CARB) for its ThermaCat(TM) Active Level III Plus catalyst system for a
multitude of on-road diesel engine applications including school buses. While
waiting for the CARB verification and to facilitate the return of the school bus
back to First Student for service carrying children, ESWC applied and received a
CARB Experimental Permit for operation on California roads for this vehicle.

The ThermaCat(TM) system monitors engine exhaust temperature and pressure,
determines when the required conditions are met and creates a diesel fuel based
exothermic temperature increase into the Diesel Particulate Filter (DPF). This
repeated, controlled process of regenerating the collected Particulate Matter
(PM) stored in the DPF in real-time engine operation lowers the systems
backpressure. By doing so, the ThermaCat(TM) maintains optimized emissions
reductions in cold or inconsistent duty cycle applications without the need for
operator interface, expensive equipment downtime or daily maintenance intervals.
This unique approach, coupled with added safety features, gives the
ThermaCat(TM) Active Level III Plus catalyst system a large potential cross
section and demographic of on-road applications including school buses.

"Terry Smith, Director of Parts Sales Westrux International stated. The
ThermaCat(TM) Active Level III Catalyst System offers many user friendly
advantages to our very large customer base in Southern California. Being that
regeneration occurs during normal operation with no impact on drivability or
performance; this is a huge advantage for our customers in order for them to
maintain route schedules without costly downtime. We are looking forward to
playing a significant part in the push to clean up the air quality in the Los
Angeles community."

"David J. Johnson, ESW's President and CEO commented. The current North American
market consists of a total estimated population in excess of 490,000 school
buses, of which California represents an estimated 25,317 vehicles. These
numbers did not go unnoticed when we began this comprehensive program two years
ago. Our goal from the beginning was to bring what we believe to be the safest,
most efficient diesel emission reduction technology to this sector of our
industry with the focus on safety first. CHP's approval of the ThermaCat's(TM)
first school bus installation we believe validates that we have done just that.
We are looking forward to working through our North American distribution
network with potential customers like First Student as the future unfolds."
