Retailers are expected to shutter some barbecue grills and mobile barbecue grilling units in the next three years.
The Hawaiian barbecue grill market is expected to reach $1.7 billion by 2022, according to research firm Euromonitor International.
Restaurants are expected sell more than 30,000 of them a year by 2022.
The companies are also expected to close some smaller grill units.
A source told Reuters that the closures are expected in the coming years, and are likely to be for two reasons: 1) The market for portable grills has become less attractive, and 2) the industry has slowed down due to tighter environmental regulations.
The industry is also facing challenges.
The Hawaii Department of Land and Natural Resources has been cracking down on the export of some imported products that are made from wood products like barbecued pork, the source said.
It has banned a range of products that could contain harmful substances.
