A factory license ensures compliance with environmental regulations and labor laws in manufacturing units. Under the Factories Act, factories must adhere to environmental norms, including waste management, water and air pollution control, and safe disposal practices. They must obtain necessary permits for effluent treatment, emissions, and hazardous waste disposal. Compliance with environmental standards is monitored through regular inspections by authorities. Additionally, factories need to implement systems like sewage treatment plants (STP), effluent treatment plants (ETP), and adhere to guidelines for noise and chemical handling. Non-compliance can result in penalties, shutdowns, or legal consequences, emphasizing the importance of maintaining environmental standards.
