Water is an essential resource in the pharmaceutical process of Oneness Biotech. Water plays a key role in the cultivation of botanical raw materials, active pharmaceutical ingredients (APIs), and the preparation of medicines and medical supplements. As a pharmaceutical company committed to sustainable development, we have completed the assessment and mitigation of the risks associated with water quality deterioration, scarcity, and water use and wastewater management.
Water Risk Analysis
After assessment, all of our operations and the cultivation of our main raw materials are located in areas with low water supply risk, and there is no risk of immediate water shortage. However, as the impact of global climate change intensifies, there is a high degree of uncertainty in the stable long-term supply of water resources. To cope with possible future water shortage challenges, we are committed to promoting good water resources management, including effective use of water resources and stringent measures for treatment of water discharges.
Water Withdrawal (Unit：M3)
To enhance water conservation and management, it is appropriate to regularly collect water usage data and implement comprehensive water monitoring. However, the building management unit of Nangang Laboratory was unable to provide information on water charges, and Cotton Field Organic Farm uses groundwater which has not been tallied the consumption. Both were not included in the statistics. All withdrawal is from fresh water. According to the WRI data, Taiwan is categorized as a low-medium (1-2) area in the Baseline Water Stress Map.
Note: The subsidiary, Cotton Field Organic Farm, sources its water from groundwater, and the water usage cannot be quantified.
Water Pollution Prevention and Control
In order to mitigate the potential environmental impact of the operations, the wastewater treatment of Oneness Biotech complies with the requirements of environmental laws and regulations. The scope of wastewater volume surveys includes the parent company and subsidiaries. However, wastewater from the Xinyi and Nangang locations is discharged into municipal sewages for treatment, while Cotton Field Organic Farm’s wastewater is discharged into local channels, making it impossible to quantify. By monitoring water consumption and responsibly disposing wastewater, we not only mitigate our environmental impact but also contribute to the long-term resilience and equity of water rights in the region.
Wastewater Quality Improvement Measures
The Nanchou Plant conducts wastewater treatment according to high standards. In addition to avoiding pollutants at the source, and no heavy metals or harmful chemical substances infiltrated during the manufacturing process, the use of the Up flow anaerobic sludge bed treatment (UASB) and the BioNET systems developed and designed by ITRI allows wastewater to be treated using biological methods. By doing this, we can reduce the use of chemicals, achieving the goal of zero impact on natural water bodies.
We continue to improve the effectiveness of wastewater treatment, control discharge water quality to comply with legal regulations, and regularly monitor the COD value of raw water to make timely adjustments to treatment conditions (e.g. treatment volume, treatment time, pH value of wastewater) based on changes in COD value. Moreover, we use long-term domestication to strengthen the anaerobic bacterial in order to achieve the anaerobic bacterial phase that can tolerate a high ammonia nitrogen environment and increase the COD treatment capacity of raw water.
Wastewater Monitoring
The Nanchou Plant operates in a higher standard than the legal requirements, and a third-party impartial unit is commissioned to test whether the discharged water meets the legal discharge standards every 6 months. Meanwhile, Oneness Biotech understands that the area around Nanchou Plant contains a large amount of farmland. In order to let stakeholders understand the quality of the discharged water, Oneness Biotech actively conducts sampling and analysis of the discharged water quality on a “daily” basis. The data obtained is all in line with the discharged water standards and is publicly disclosed on the official website of Oneness Biotech (View data below).
