This past year has been one long foodservice success story, and as restaurant owners brace themselves for 2016, they'll have a lot of support from their past prosperity.

According to the latest Restaurant Performance Index released by the National Restaurant Association, the food service industry has seen remarkable boosts across many crucial metrics between October 2014 and October 2015, indicating positive, sustainable growth and faith in a strong economy. Same-store sales continue to increase over the 20th consecutive month, and customer traffic is up 41 percent from last year.

Greener packaging
Perhaps foodies visiting their local eateries have already noticed a change in the color and stock of the containers holding their leftovers. Interested in reshaping their resource spend to demonstrate a more environmentally friendly attitude, many restaurants have sought out greener packaging options to appease both customers and their bottom lines.

"What's notable this year is the overwhelming number of mentions related to compostable packaging," said Lynn Dyer, president of the Foodservice Packaging Institute, in a recent press release. As such, manufacturers specializing in packaging have had to step up their game to meet client and end-user demand for these materials.

Larger food service businesses in good fiscal standing will likely spend a portion of their 2015 gains on discovering newer, more efficient ways to either begin producing ecological packaging or automate processes they already have in place through supply chain partners. Smaller businesses won't miss out either – though they may not be able to innovate firsthand, their newfound remuneration affords them the opportunity to seek out green packaging manufacturers that may have once been above their pay grade.

Across the board, restaurant owners can turn considerable gains in 2015 into wild successes in 2016, so long as they're willing to put their money where their customers' mouths are.
