If you eat at McDonald's often, then you've probably noticed that the fast food chain changes its packaging every couple of years.

Last year, they introduced new cups, sandwich boxes, and takeout bags, and according to McDonald's spokeswoman Becca Harry, the chain wanted a look that is "fresh and consistent with our vision to be a modern and progressive burger company."

The company brought back the brown paper bags, which is a drastic change from the white bags they've offered for 13 years, from 2003 until 2016.

Turns out, the switch to the brown bags goes beyond aesthetics. The company has reportedly been trying to become more environmentally conscious, and although you may not necessarily notice it right away, there will be more changes coming into effect soon.

According to multiple outlets, once the demand for the chain to offer all-day breakfast was fulfilled, McDonald's switched its focus onto making another customer request a reality: making its packaging eco-friendly.

"We have a responsibility to use our scale for good to make changes that will have a meaningful impact across the globe," Francesca DeBiase, McDonald's chief supply chain and sustainability officer, told Reuters.

The company has set a goal to become 100% environmentally-friendly by 2025, but at this time, only half of its packaging are sourced from recyclable, renewable, or certified sources, and recycling is only offered at ten percent of McDonald's locations.

One of the bigger changes you may be able to see by the end of the year is the elimination of plastic foam cups. Some locations have been serving drinks in cups made out of polystyrene, which is almost impossible to recycle.

The designs on the packages are also a big part of the McDonald's experience, so there's a possibility that we could also be seeing some new illustrations on the cups, french fry containers, paper bags, and sandwich boxes in the near future.
