Definition and Sources of Hazardous and Toxic Waste (B3)
📌 Hazardous and Toxic Waste (B3) is defined by Government Regulation No. 101 of 2014 as waste from a business or activity containing hazardous and/or toxic materials.
☣️ B3 waste poses serious risks, including water, soil, and air pollution, and can cause illness or death to humans, animals, and microorganisms.
🏭 Common sources of B3 waste include chemical and pharmaceutical industries, hospitals, laboratories, mining, and textile/metal industries.
💧 The four general types of B3 waste discussed are liquid, solid, gas, and medical waste.

Characteristics of Hazardous and Toxic Waste (B3)
💥 According to the Minister of Environment and Forestry Regulation No. 6 of 2021, B3 waste characteristics include explosive, flammable, reactive, infectious, corrosive, toxic, and environmentally hazardous.
🔥 Flammable waste includes solvents like benzene, toluene, and acetone from paint, ink, or metal cleaning industries, as well as unused fuel spills.
🧪 Reactive waste may cause unwanted reactions (gas release, explosion) when interacting with water, air, or other chemicals, citing examples like cyanide waste, sulfuric acid ($\text{H}_2\text{SO}_4$), and nitric acid ($\text{HNO}_3$).
🩺 Infectious B3 waste contains pathogenic microorganisms, often stemming from medical sources like used syringes, bodily fluids, or laboratory waste from animal testing.

B3 Waste Management Stages and Regulation
1️⃣ Initial mandatory steps include identification and classification (sorting into organic, non-organic, and B3) to simplify downstream processes.
2️⃣ Proper packaging and labeling are crucial to prevent leaks and inform handlers about the waste type and hazards, followed by temporary storage before transfer.
🤝 Management typically involves hiring third-party transporters and managers who possess valid permits/certificates for handling, utilizing, or disposing of the B3 waste.
📜 Regulatory frameworks governing B3 management include Law No. 32 of 2009 on Environmental Protection and Management and Government Regulation No. 101 of 2014.

B3 Waste Treatment Methods
⚙️ Common treatment methods include physical processes like filtration and sedimentation.
🧪 Chemical treatments involve processes such as neutralization and oxidation-reduction.
🔥 Thermal treatment is achieved primarily through incineration, while stabilization/solidification converts the waste into a stable solid form.

Key Points & Insights
➡️ Strict adherence to regulations (UU No. 32/2009 and PP No. 101/2014) and rigorous supervision are essential for effective B3 waste management.
⚠️ Prioritize safety and mandatory use of Personal Protective Equipment (APD) when working near or handling any materials suspected to be B3 waste.
➡️ Case Example: $\text{PT Gamabunta}$ (generator of Fly Ash) collaborated with $\text{PT Ksuyu}$ (transporter) to deliver waste to $\text{PT Manda}$ (utilizer) for use as raw material in cement production.
