Reduction in Hazardous Waste

Historically, the Amnicola site disposed of

approximately 200,000 pounds of reclaimed styrene

every year.

Created an onsite recycling program to reclaim

styrene previously disposed as hazardous waste.

Reduction in Hazardous Waste

Found a buyer to use the styrene as a raw

material in another manufacturing process.

Results:

Reduced disposal costs

Reduced regulatory fees

The facility’s hazardous waste generator

status was reduced from a Large Quantity

Generator to a Conditionally Exempt Small

Quantity Generator.

25+ years of Leadership in

High-Performance Computing

Recent challenge: Design a more energy-efficient and

water-efficient system to run a computer 8 times

more powerful.

Summit system is capable performing 200 petaflops =

200,000 trillion calculations a second.

Upgrading & Integrating

New Designs

Challenge: Accommodate 20MW of

additional cooling load

Overhauled three 1,200-ton chillers.

Increased efficiency by up to 10%.

Designed new system to use warm

(70°F) water instead of conventional

cool water system. (saved $3.7m in

construction costs)

Data Center Power Use Efficiency

Net Results: Power Use Efficiency (PUE)

FY 2017 : 1.36 PUE

FY 2018 : 1.15 PUE

On track to be 15% more efficient than previous system

Computer uses 1/6th of the energy as its predecessor,

while producing more than 12 billion floating point

calculations per watt.

Wetland Restoration

Restored 88 acres of wetlands destroyed when the

site was a U.S. Army munitions base in the 1940-

1960s.

Wetland Restoration

Starting with 40 acres, the project grew to 88 acres.

Now home to hundreds of species of wildlife,

including 167 species of birds that migrate through

the property or have taken up residence.

Plan for Education Field Trips

The VW team is ready to begin hosting environmental

education on the property.

They picture school trips, aquarium guests and others

coming to learn.

Enjoy Nature & the biodiversity of wetlands.
