Improper disposal of pharmaceutical waste can lead to environmental pollution and potential health hazards. Safe disposal methods include high-temperature incineration or chemical treatment.
4. J120 – Waste Solvents
J120 covers waste oils other than mineral oils, such as synthetic lubricants and cutting fluids. Like J100, these oils require specialized disposal or recycling to prevent pollution. Waste oils can sometimes be re-refined into new lubricants or used in energy recovery processes.
J120 includes waste solvents used in industrial applications such as cleaning, painting, and degreasing. Examples include:
- Acetone
- Toluene
- Methanol
- Xylene
Waste solvents are flammable and may emit toxic fumes, making their proper handling crucial. Recycling through distillation and recovery processes is a preferred method of disposal.
5. K130 – Grease Trap Waste
K130 refers to biosolids and sludge generated from wastewater treatment plants. This waste can contain pathogens, heavy metals, and organic contaminants. Proper treatment and disposal methods, such as composting or incineration, are necessary to ensure safe environmental management. Some treated sewage sludge is repurposed as fertilizer under strict regulations.
K130 consists of waste collected from grease traps in restaurants, food processing plants, and other facilities. It includes:
- Fats, oils, and grease (FOG)
- Food scraps and organic matter
- Contaminated wastewater
Grease trap waste must be processed at licensed facilities to separate water and solids before safe disposal or conversion into biofuels.
6. N140 – Nickel and Its Compounds
N140 includes solid and liquid waste generated from the manufacturing and use of adhesives, resins, and related products. These wastes may contain volatile organic compounds (VOCs) and hazardous chemicals that require proper handling and disposal. Treatment options include incineration, chemical stabilization, or recycling where possible.
N140 pertains to waste containing nickel and its compounds, often generated from industrial activities such as electroplating, battery manufacturing, and welding. Examples include:
- Nickel plating residues
- Nickel catalysts
- Spent nickel-containing solutions
Nickel waste is classified as hazardous and must be managed to prevent soil and water contamination. Recycling and proper chemical treatment are recommended disposal methods.
7. M205 – Laboratory Waste
M205 covers waste contaminated with PFAS chemicals, which are commonly found in firefighting foams, non-stick coatings, and industrial applications. PFAS are persistent in the environment and can pose health risks. Proper containment, incineration, or specialized treatment is necessary to mitigate their impact.
M205 covers chemical waste generated from laboratories, including research facilities, educational institutions, and medical centers. This category includes:
- Expired reagents and chemicals
- Used test kits
- Contaminated lab equipment and glassware
Laboratory waste must be handled carefully, segregated based on chemical properties, and disposed of through licensed hazardous waste facilities.
8. B100 – Acidic Waste
B100 includes waste acids from industrial processes, such as sulfuric acid, hydrochloric acid, and nitric acid. These substances can be highly corrosive and dangerous if not handled properly. Neutralization and safe disposal methods are required to prevent harm to people and the environment.
B100 refers to waste acids that result from industrial processes such as metal treatment, chemical manufacturing, and battery production. Common examples include:
- Sulfuric acid
- Hydrochloric acid
