# Principles of Green Hospitals Green hospitals are healthcare facilities designed and operated in a way that protects human health while reducing environmental impacts. Hospitals consume large quantities of water, energy, medicines, chemicals and other resources and generate different types of waste, including infectious, hazardous, pharmaceutical, recyclable and general waste. Therefore, the concept of a green hospital is especially important in waste management. A green hospital seeks to provide safe and effective healthcare while minimizing pollution, conserving natural resources, reducing waste generation and promoting sustainable practices. The principles of green hospitals are based on prevention, resource conservation, environmental protection, safe waste handling and continuous improvement. One of the most important principles of a green hospital is waste prevention and minimization. Waste should be reduced at its source rather than relying only on treatment or disposal after it has been generated. Hospitals can minimize waste by purchasing products with less packaging, avoiding unnecessary disposable items, using materials efficiently and adopting appropriate inventory-management systems. Staff should be trained to distinguish between essential and unnecessary use of materials. Preventing waste at the source reduces the quantity of waste requiring treatment and disposal and also lowers operational costs. Another important principle is proper segregation of waste at the point of generation. Healthcare waste should be separated immediately according to its type and level of risk.
