MillerCoors Trenton Brewery is set to invest around $25m in 2012 to streamline its process, save money and improve safety.

MillerCoors Trenton interim vice president Jon Hussey said the 111-acre brewery is adding cardboard box manufacturing shop on site to hold its glass bottles.

"We would previously buy those cardboard cases prefabricated then fill them with bottles at the brewery," said Hussey.

"It also is a huge sustainability initiative because we’re going to greatly reduce the amount of fuel it takes to bring … the glass and containers into the brewery."

According to Hussey, the box shop will generate ‘significant cost savings’ in terms of manpower and shipping.

Production at the box manufacturing is expected to start by the end of 2012.

He said the company is also planning to invest around $4.5m next month to increase its capacity to filter draft brews.

"It gives the company as a whole better flexibility on where they can move draft product lines," he said.

Last year, MillerCoors has produced many videos for employees to help show the importance of safety, including one video on proper eye protection and also installed orange seat belts on all fork trucks.

"The ultimate goal is that everyone is thinking about safety first before anything else and we can certainly see that happening," Hussey said.

Compared to 2010, MillerCoors has improved by 33% in all three key safety indices in 2011.

MillerCoors Trenton Brewery, which is said to be the largest in Ohio and second largest producer of MillerCoors, has the capacity to brew 11 million barrels of beer per year and employs around 550 people.

The brewery produces 65 different brands including Molson Golden and Molson Ice.

"We may grow to introduce two new (Molson Coors) brands this year," Hussey added.
