According to Darsono (2013:245), Hazardous and Toxic Waste (B3) is the residual result of a production process activity that contains B3, whether due to its nature, concentration or amount which can pollute the environment and endanger health.
B3 waste has certain properties that make it dangerous, namely, explosive, flammable, corrosive, infectious, toxic, dangerous for the environment, and reactive.
B3 waste management has great potential to pollute the ecosystem, here are several methods for managing B3 waste.
Management by Chemical Methods
Chemical waste management is carried out to remove particles that are difficult to settle, heavy metals, phosphorus compounds and toxic organic substances. B3 waste processing with chemicals is carried out using the stabilization or solidification method. The addition of reagents aims to minimize the solution, movement and spread of toxic waste before disposal.
Examples of materials used are cement, lime and thermoplastic materials. The advantages of the chemical management process include that it is not affected by toxic pollutants and does not depend on changes in concentration.

Management by Physical Means
Physical waste management is carried out by removing large suspended materials that easily settle or float. This management method is used to remove suspended material or concentrate sedimentary sludge by providing upward air flow.
Management by Biological Methods
This method is also known as bioremediation and phytoremediation. Bioremediation is waste management using bacteria or other microorganisms to break down B3 waste. Meanwhile, phytoremediation is waste management using plants to accumulate toxic materials from the soil.
In various activities, whether from the industrial, household or medical sectors, waste often results that cannot be avoided. Therefore, B3 waste management requires special regulations to maintain environmental safety and sustainability to minimize negative impacts on the environment and the health of living creatures.
