The "We use algae to improve the soil" activity

On December 24, 2025, Taokaenoi donated 650 kilograms of soil conditioner, a byproduct of managing algae waste and sludge from water treatment at its two factories: the Rojana and Nopawong plants. They also participated in planting vegetables with students from Wat Nong Mai Sung School in Uthai District, Phra Nakhon Si Ayutthaya Province. The conditioner will be used in the school's vegetable gardening project and in creating a forest garden to help absorb carbon dioxide.
