00:00:01.880 --> 00:00:07.720
Deep beneath the earth in southwestern
Wyoming, trona ore is mined and purified

2
00:00:07.920 --> 00:00:11.920
to soda ash, the starting material
for sodium bicarbonate.

3
00:00:12.120 --> 00:00:16.960
The soda ash arrives by rail at one
of Arm and Hammer's two dedicated sodium

4
00:00:17.160 --> 00:00:20.720
bicarbonate manufacturing
facilities in the U.S.

5
00:00:20.920 --> 00:00:22.960
The soda ash is dissolved in water

6
00:00:23.160 --> 00:00:27.400
and filtered for purity before
entering the carbonation column.

7
00:00:27.600 --> 00:00:29.840
As carbon dioxide is bubbled through

8
00:00:30.040 --> 00:00:34.160
the column, crystals of sodium
bicarbonate are formed.

9
00:00:34.360 --> 00:00:35.800
The crystals are dewatered

10
00:00:36.000 --> 00:00:42.040
in the centrifuge and then carefully
dried in a three story tray dryer.

11
00:00:42.240 --> 00:00:46.680
Bucket elevators carefully convey
the crystals to sifters where they are

12
00:00:46.880 --> 00:00:51.440
separated by particle size
and stored in bulk storage bins.

13
00:00:51.640 --> 00:00:57.040
After careful testing to USP standards,
the sodium bicarbonate passes through our

14
00:00:57.240 --> 00:01:04.080
product protection systems and is
filled in bags, sacks or bulk trucks.

15
00:01:04.360 --> 00:01:09.000
Both our locations are registered
and inspected by the FDA and comply

16
00:01:09.200 --> 00:01:14.760
with the Food Safety Modernization Act
and current Good Manufacturing Practices.

17
00:01:14.960 --> 00:01:17.440
Our quality management system is subject

18
00:01:17.640 --> 00:01:22.000
to annual certification under
the Global Food Safety Initiative

19
00:01:22.200 --> 00:01:25.240
and the BRC Food Safety Standard is fully

20
00:01:25.440 --> 00:01:30.800
implemented at both plants so
that we are audit ready every day.

21
00:01:31.000 --> 00:01:33.640
Our warehouse management system controls

22
00:01:33.840 --> 00:01:39.240
inventory and shipments to customers
across North America and around the world.

23
00:01:39.440 --> 00:01:45.440
Arm and Hammer has been the standard
of purity and quality for over 170 years.

24
00:01:45.640 --> 00:01:49.520
One more reason to trust
The Bicarbonate Experts.
