Tetra Pak, the Swedish food processing and packaging giant, recently committed itself to increase its use of renewable electricity from 20 percent to 100 percent across all of its global operations by 2030. One of Tetra Pak's packaging plants in China has been playing a leading role in reaching this ambitious goal for seven years - thanks to the rapid development of two dairy companies, Yili and Mengniu, in Inner Mongolia autonomous region.

Tetra Pak launched its fourth Chinese factory in Hohhot, the capital city of the region. The plant is the most productive in the company, expecting to manufacture 40 percent of Tetra Pak's total output in the country this year.

The facility relied entirely on renewable energy by 2009, the first in China to achieve this. The estimated 20 million kWh of green power consumed on the site annually is supplied primarily from wind turbines.
