Under the initiative of the President of Mongolia and as part of the “Billion Trees” national movement, 35,000 trees are being planted in October around six gorges of Bogd Khan Mountain, specifically near the Baruun Zalaat area. These newly planted trees are being watered with purified water from the MCS Coca-Cola factory.

MCS Coca-Cola was the first among Mongolian food manufacturers to establish a wastewater purification facility in 2010. This facility can purify 99% of all water used in the factory’s technological processes. The purified water from this facility fully complies with:
- MNS 4943 : 2015 standard “Requirements for water supplied to the environment”
- MNS 6734 : 2018 standard “General requirements for reused purified water and technical water”

Minister of Environment and Tourism, B. Bat-Erdene, stated:
In the “Billion Trees” national movement, to ensure the planted trees provide economic benefits, the government promotes the use of greywater or reservoir water for irrigation rather than potable water. Organizations that purify and reuse industrial water need economic incentives, such as exemptions from water fees, and we plan to focus on creating such a legal environment.

Director of the Forest Agency, B. Oyunsanaa, added: The trees in the six gorges of Bogd Khan Mountain will receive autumn irrigation now and another irrigation during spring snowmelt. Trees generally do not require water unless pollution levels are very high. The purified water from MCS Coca-Cola meets standards suitable for purposes other than drinking, making it fully appropriate for tree irrigation.
