Garbage collectors are responsible for collecting garbage in alleys and alleys (where big trucks can't reach), sweeping public areas, mowing the grass in the bushes between the two roadsides, etc. At the designated hours. According to regulations available (6 - 7 am; 17 - 20 pm - depending on the area), they will move garbage collection trucks to push their hands around every corner and use gongs and bells to notify people to bring garbage to the car. In addition to collecting waste in the assigned area, they are also the ones who directly handle the waste and sort it before it is returned to the final collection place. This treatment helps waste to be classified in detail, and at the same time reduces the burden on the environment in the face of the increasing plastic waste in urban areas. Environmental workers are the unsung heroes of the city. We have a clean, fresh living space. They work from early morning until late at night, from winter to summer, regardless of the sun and rain everywhere from small alleys to main roads. Their job seems simple, but it is not easy. Sanitation workers are people who are directly exposed to toxic substances, bacteria, viruses, etc. produced by waste. Domestic waste often contains a large amount of organic matter. These substances are easy to decompose, cause stench, grow bacteria, attract rats, flies, mosquitoes, cockroaches, etc. Continuous exposure to countless disease-causing organisms in waste can cause body debilitation. , even lead to death. Not only that, sanitation workers also face the danger of life-threatening traffic accidents, especially those who work night shifts. Despite the risks and harsh conditions of the job, sanitation workers continue to do their jobs.
