What is Hazardous Waste? How to Manage it Safely?Hazardous waste, while seemingly distant, is actually very close to us. These wastes are mixed in our daily lives, such as batteries, sprays, or even expired medicines. Improper waste management can affect health and the environment. Managing hazardous waste isn't difficult. Here's how. What is Hazardous Waste?Hazardous waste is toxic waste or waste containing various hazardous chemicals. It is flammable, corrosive, or toxic, causing harm to health and the environment. Types of Hazardous WasteFlammable waste: Hazardous waste containing easily flammable chemicals, such as cooking gas, fuel oil, or thinner.Toxic waste: Hazardous waste containing chemicals harmful to the human body. Do not inhale, touch, or ingest. Examples include toilet bowl cleaner, insecticides, and mercury in light bulbs.Corrosive substances: Hazardous waste containing chemicals that corrode metals, skin, or other materials, such as battery acid and drain cleaners.Infectious waste: Hazardous waste containing infectious agents, such as used syringes, bandages, and blood-stained cotton pads. Examples of Hazardous WasteNow that we know the types of hazardous waste, let's look at some examples found in daily life. BatteriesA very common hazardous waste found at home includes AA, AAA, and lithium batteries. These contain heavy metals such as mercury, lead, or manganese. If ingested, they can cause headaches, fatigue, cramps in the arms and legs, or encephalitis. Various Types of Light BulbsHazardous waste found in homes includes fluorescent and neon lights. They contain toxic mercury. If ingested, it can cause skin irritation, swollen gums, gingivitis, severe diarrhea, and frequent muscle spasms. Electronic DevicesChargers, old phones, mice, and plugs are all hazardous waste containing electrical circuits, heavy metals, or hazardous chemicals such as lead, which directly affects the nervous system and memory, or lithium, which can cause skin burns and scalding. Car BatteriesAn essential component in cars containing lead is considered hazardous waste that should be properly sorted. If ingested, it can cause headaches, fatigue, muscle aches, seizures, and even loss of consciousness. Spray CansHazardous waste that is easily flammable and contains lead. If inhaled in large quantities, it can cause fatigue, headaches, malaise, and in severe cases, seizures or loss of consciousness. InsecticidesInsecticides often contain DDT, Carbamates, and Pyrethroids. If ingested, they damage the central nervous system, causing seizures, convulsions, or paralysis. They also damage the liver, kidneys, and hormonal systems. High levels of accumulation can increase the risk of cancer.Correction Fluid(Parents should be cautious) This hazardous waste is easily accessible to children. It contains Trichloroethane (TCE), Toluene, and Acetone. If ingested, it damages the respiratory mucosa and nervous system. Printer and Photocopier InkPrinter and photocopier ink contains Carbon black, Toner resin, Styrene, Benzene, and heavy metals. Frequent inhalation causes lung irritation. Styrene and Benzene are carcinogens. Expired MedicinesMedicines have long shelf lives but do expire. Taking expired medicine can lead to drug resistance. Some medications may produce new toxins, causing acute liver or kidney failure. Some medications, such as Tetracycline, can become severely toxic when expired. Always check the expiration date before taking medication. Engine OilEngine oil is hazardous waste that often contains Hydrocarbons, heavy metals, and carcinogens such as Benzene. It affects both the environment and human health, causing skin irritation or a burning sensation in the nose if inhaled. How to Manage Hazardous WasteSecure Storage Before DisposalStore in the original container or a leak-proof container, such as a black bag or several layers of paper. Label clearly with "Toxic Waste" or "Hazardous Waste" for easy identification by officials and for safe handling to prevent harm to handlers and others responsible. Separate Hazardous Waste from Other Types of WasteSeparate waste using hazardous waste bins that are red, have red lids, or clearly indicate "Hazardous Waste" on the side. These bins are specifically for hazardous waste that impacts health and the environment, such as batteries, light bulbs, or chemical containers.Hazardous waste should never be mixed with other waste types. Currently, there are four types of bins for pre-disposal sorting, also known as four-color bins: The Four Colors of Waste BinsGreen bin (wet waste): For naturally degradable waste such as food scraps and leaves.Blue bin (dry waste): For non-degradable waste or waste that is not cost-effective to recycle such as foam and plastic bags.Yellow bin (recycling bin): For recyclable waste that can be reprocessed for reuse such as glass, plastic, and paper.Red bin (hazardous/infectious waste): For hazardous or infectious waste harmful to living things and the environment, such as batteries, sprays, and light bulbs. Hazardous Waste Collection PointsMunicipalities or Sub-district Administrative Organizations (SAOs): Have designated hazardous waste bins.Department stores: Such as Tesco Lotus, Big C, and Central, have collection points for batteries, light bulbs, and old electronic devices.Hospitals and government organizations: Often have programs for returning old batteries or expired medications for proper hazardous waste management, either inside or outside the building.Villages: Often have red bins or designated hazardous waste disposal points near the back of the village. To identify hazardous products or containers, look for warnings such as "Do not ingest," "Do not burn," "Danger," and symbols such as a skull (poison) or flame (flammable). Proper management is crucial to prevent harm to human health and the environment.
