(CNN) Nepal is banning single-use plastic on and around Mount Everest in a bid to cut down on the region's trash problem.

Nepalese authorities said they will ban plastic soft drink bottles and single-use plastics under 30 microns thick (0.0012 inches, or 0.03 millimeter) in the Khumbu region, which is home to Everest. The ban will prevent hikers from bringing the plastic goods in -- and stop shops from selling them.

The rules won't come into effect until January next year, and won't apply to plastic water bottles, said Ganesh Ghimire, the chief administrative officer of Khumbu Pasang Lhamu rural municipality.

"We are consulting with all sides about what can be done about plastic water bottles," he told CNN Thursday. "We will soon find a solution for that."

The rules are aimed at reducing waste in the region, which is visited by 150,000 foreign and domestic tourists a year, according to Ghimire. Visitors to Everest trek through a number of villages before they start climbing the mountain itself, often leaving large amounts of trash behind them.
