1. Design and Planning of Recycling System
The design and planning of the Southern Nevada Recycling Center was in response to
the ambitious goals of the Southern Nevada community to increase recycling for a
more sustainable future. In addition to providing the infrastructure and processing
capacity necessary to accommodate the conversion of additional Clark County Nevada
households to All-in-One Recycling™, the system was designed to support the
innovative recycling programs that are gaining momentum on the Las Vegas Strip and
throughout the region. Site development was completed in only 12 months, from the
groundbreaking in November 2014 to the grand opening at the end of 2015.

of facility
The increased volume generated through the expanded residential All-in-One
Recycling™ program, as well as the recyclables collected from residential and
commercial customers throughout the region, exceeded capacity at the existing
88,000 square foot Recycling Center. Originally, the plan was to expand the existing
recycling system. However, the extended down-time this scope of expansion would
require made this approach impractical, as the material would have to be trucked out
of state to provide interim processing capacity. Republic determined that it would be
in the best interest of the community to continue operations at the existing site and
build a new 70-ton per hour state-of-the-art recycling center adjacent to the existing
facility. This allowed Republic to continue meeting the existing recycling needs of the
community and customers while building the infrastructure required to support the
growing demands for increased capacity.

The project site presented several challenges. It is crisscrossed by several storm
channels which complicated the site layout that was required to accommodate them.
In addition, geotechnical investigation revealed poor soil conditions that required
extensive over-excavation to ensure proper building support conditions. Related to
the storm channels, there is also a mapped FEMA flood zone on the site, which limited
where the improvements could be made. These challenges presented obstacles that
were overcome with teamwork and an eye toward the final site functionality.
A facility of the ambition and scope of this project required extensive planning to
ensure it met the region’s current and future needs. The resulting Southern Nevada
Recycling Center, which is a 110,000 square foot facility adjacent to the existing
facility, is known as the “the largest and smartest residential recycling center in North
America.” The Recycling Center features dual 35-ton per hour sorting lines and can use
one or both of the sorting lines at any one time. Operators can bypass certain parts of
the system when running different material types.

A unique aspect of the planning approach was that the
building was designed as an extension of the processing
equipment. The equipment manufacturer, CP Group,
developed the 70-ton per hour system and Cambridge
Construction designed the building from that template.
The plant features a 42’ tall eave that allowed the
equipment, specifically the screens and optical sorters,
to be placed and oriented for optimum efficiency. In
addition, the bale storage and tipping areas were both
designed to be expanded in the future.

2. Use of Equipment/Systems and Technologies
The Southern Nevada Recycling Center features equipment capable of sorting 70 tons
per hour. Nearly 550,000 households in Southern Nevada now send their All-in-One
Recycling™ materials to the facility. Commercial customers send materials in either
dual-streams or All-in-One Recycling™ streams, depending on the customer.
The state-of-the-art facility features industry-leading technology, including the CP
Glass Cleanup Trommel, which is equipment that is being introduced for the first time
worldwide. This system, created by the CP Group, uses advanced technologies and
principles of engineering and physics to increase glass recovery. The system passes
materials through a trommel screen, removing glass fines, which are tiny particles, as
well as other small debris.
Glass Clean-Up System
The system uses principles of engineering
and physics to achieve glass recovery.
(L-R) glass product, non-glass contaminants
and <3/8” glass
The materials continue through a rotating drum designed to agitate its contents. At
one end of the drum, a large vacuum extracts any non-glass items. Meanwhile, denser
material – clean glass – exits the drum at the other end, where it flows into a container
and awaits additional processing. Through this first-of-its-kind technology, the system
will allow increased levels of glass recovery, which is significant due to the large
quantities generated by the Southern Nevada region’s hotels and casinos.

4. Worker Health and Safety
The success of the recycling system is directly correlated to the success of the
employees that make it work. To that end, many approaches were taken to improve
their working environment. Worker health and safety was a major consideration in
the planning and design of the facility. The system was designed to exceed American
and international standards for safety, including OSHA and NFPA compliance.
Whether the system is running at full process or in a reduced capacity, all safety
circuits throughout the facility remain active. The Southern Nevada Recycling Center
employs 160 full-time employees on three shifts, with one shift devoted to
maintenance. Since its opening, and at the time of this application submittal, zero
injuries have occurred at the Southern Nevada Recycling Center.
Building Safety Design Features
Numerous features enhance safety of the facility, including a 10’ band of translucent
panels at the eave and over 40 skylights improve indoor lighting levels. LED high bay
lights supplement the daylighting when skies are overcast or when operating at night.
Elevated lighting levels help improve safety and well-being.
Additional features include:
Dual-bag house dust suppression system, including collection hoods at dust
generation points in the system, removes particulates from the air, and
improves the quality of indoor air for employees.
Misting system for employee comfort uses finely atomized water droplets that
cause evaporative cooling to lower temperatures. Several 12’ diameter highvolume low-speed fans help circulate air to improve worker comfort.

Comfortable break room and locker room facilities for the facility staff, and an
elevated walkway that links the employee amenity areas to the equipment,
which prevents employees being on the floor, vulnerable to vehicle impact.
Processing System Safety Design Features
Numerous design elements were included in the system to facilitate and enhance
operational safety. The system uses Miller Temporary Anchorage Connectors, which
wrap around l-beams and other structures for supporting workers. Crossbars above
the rotors are dimensioned to hold one person each and provide valid anchor points
for lanyards. All disc drives on each screen have brake motors with locking hand
release levers. Brakes are activated when the power goes off, locking rotors. Rotors
cannot turn when maintenance personnel are walking or standing on them.
The system design also allows easy access to maintenance areas and includes
safeguards built in to protect workers such as trap key systems, hydraulic platforms,
and lanyard connections. All sorters are on the same platform level for safety and
operator supervision. Additionally, a single emergency stop system provides 100%
equipment control while maintaining maximum uptime. Intelligent controls know
exactly when and where an e-stop is triggered, allowing quick identification and
correction to resume production.
The facility also features trapped key
interlocking, which utilizes locks and
keys for sequential control of equipment
and machinery to ensure safe operation.
Trapped key interlocks are used to
ensure safe access to potentially live
equipment in the plant. A safe sequence
of operations is enabled through
transfer of keys that are either trapped
Keylock System
or released in a predetermined order. For
example, a key is used to isolate a power source (circuit breaker or supply valve), this
key is then released and can then be used to gain access through a gate or door to a
high risk area by inserting it into an access lock. The key will then remain trapped until
the gate or door is closed, ensuring that the gate or door cannot be closed and the
initial key released until this personnel or safety key is returned. Access doors contain
a keylock system. The power is shut off when the access doors are opened. With the
double key system, the machine cannot be started while the doors are unlocked.

Safety Training
Safety is Republic’s highest priority and therefore, a strict policy of safety protocols
has been created with supporting infrastructure, where employees are trained to
think, choose, and work within a training framework designed for safety. Employees
are trained on the first day of employment on key safety topics, then receive refresher
training on these topics during monthly safety meetings. Employees also participate
in Republic Services’ Focus 6 program which trains employees on the skills to avoid the
six most serious types of losses in the industry.

5. Performance, Economics and Cost-Effectiveness
The Southern Nevada Recycling Center dual line processing system has proven
capable of operating at its anticipated production rate of 70 tons per hour. The system
has been performance tested by a third party expert and has met and exceeded the
high Republic Services standards.
The system achieves 98 percent purity requirements on container grades and
newspaper, achieves 95 percent purity requirement for fiber content of mixed paper,
achieves over 92 percent glass content purity on a requirement of 90 percent. The
system has also exceeded expectations in reliability, with an average uptime of 92
percent as compared to an industry average goal of 90 percent.
In addition to the numerous performance capabilities and operational goals achieved
by the system, the versatility of the line and ability to accommodate the expanding
volume of recyclables in the region was a critical deliverable realized as a result of the
planning, construction and operation of the facility.
Additionally, the system has achieved economic milestones:
The initial investment in the facility was as planned and construction was
completed within budget.
The facility is anticipated to reach profitability sooner than expected.
While these are welcome achievements, the anticipated payoff associated with the
versatility of the processing line will be even stronger. Republic Services is committed
to providing the recycling infrastructure needed to support the growing demand for
