Waste fluorescent tubes belong to hazardous waste. During treatment, attention should be paid to putting them into hazardous waste bins for special treatment.
Fluorescent lamps contain six harmful elements and substances such as lead, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers, which are distributed in three parts: capillary, lamp cap and ballast. The lamp tube contains liquid metal mercury, which is commonly known as mercury. Once the waste lamp tube is damaged, it will emit mercury vapor to the surrounding, which will be harmful to human health.
From the classification methods of domestic waste in various cities, it is roughly classified according to the composition and production of waste, combined with the resource utilization and treatment methods of local waste. For example, Germany is generally divided into paper, glass, metal and plastic; Australia is generally divided into compostable waste, recyclable waste and non recyclable waste; Japan is generally divided into plastic bottles, recyclable plastics, other plastics, resource waste, large-scale waste, combustible waste, non combustible waste and harmful waste, etc.
