The Common Water Hyacinth is a free floating aquatic plant with thick, wide and waxy leaves. The plant is native to the Amazon River Basin and after being introduced as an ornamental plant to different nations in the early 20th century is now one of the most widely distributed plant species in the world.

As a highly aggressive and invasive species, it propagates rapidly and has suffocated lakes, rivers, and waterways in locations as far reaching as Congo, Australia, Cambodia and Thailand. Infestations of Hyacinth can double in size every 2 weeks and its seeds remain viable for more than 20 years, resulting in dense mats forming on the surface of water bodies.

The excessive build-up of Common Water Hyacinth in waterways has caused Thai authorities to declare this as a serious national issue.

On the 3rd of July 2020, HMC's Public Affairs Manager, Khun Buphaphan Phantong, contributed sponsorship on behalf of HMC for the supply of equipment and manpower for the clear up of Common Water Hyacinth and unwanted flora in the Payoon community public water resource within the Ban Chang district of Rayong province.

The purpose of this activity was to remove the excess amount of Hyacinth and unwanted flora which significantly reduces the quality of water used by agriculturists in the Ban Chang area. The program to reduce the influence of Hyacinth growth also encourages local participation and raises awareness of environmental management among community, industrial, government and public sectors.

The waste product of the invasive water Hyacinth and unwanted flora removed from local waterways is converted into an organic fertilizer for agricultural use in the Ban Chang area.
