Environmental pollution refers to the introduction of living organisms, substances, energy, or other components into the environment as a result of human activities or actions by other legal entities. One particular instance of environmental pollution is the contamination of water due to the improper disposal of hazardous and toxic waste materials (classified as B3 waste). Limited liability companies are legal entities that often possess the potential to cause environmental pollution in the course of their business operations. In environmental law, the principle of strict liability is recognized, which holds the defendant accountable without requiring proof of fault. The case of PT How Are You Indonesia serves as an example of the application of strict liability in practice. This study employs normative legal methods, utilizing secondary data such as books, laws and regulations, journals, and other relevant sources obtained through library research. Through the analysis, it is concluded that the responsibility for environmental pollution, whether caused intentionally or unintentionally, rests with the director of a limited liability company. The utilization of strict liability in environmental cases is applicable in specific situations, particularly those with severe impacts on the environment and human life. While the element of fault need not be proven, the plaintiff must demonstrate that the defendant's activities have significant adverse effects on the environment and human beings, resulting in damages caused by environmental pollution.
