An LEED Existing Building Gold certificate from the US Green Building Council has been awarded to PepsiCo's Frito-Lay Topeka unit in Kansas, US.
It is the company's second manufacturing site in the nation and the first in Kansas state to achieve this rating.
The 30-year-old-building was recently upgraded with a number of sustainable design and construction features, and water reduction technologies and practices, as well as improved waste management.
The company installed high-efficiency oven burners and new lighting systems with sensors at the facility, thereby reducing its natural gas consumption by 39% and its electricity use by 27%.
By implementing new operation and sanitation practices, the facility has reduced its water consumption by nearly 52% and an employee-led recycling programme makes sure that less than 1% of the facility's solid waste goes to landfill.
Frito-Lay North America is the convenient foods business unit of PepsiCo.
