Solid waste management -1

A mature and responsible approach to solid waste management begins at the end of the 19th century

Until the end of 320 BC in Athens, solid wastes were thrown unpaved on open fields and accumulated vigorously on paths, plots or land. However, when such things were done on a daily basis, a law banning these throws was eventually passed and became a blessing for all ecology. But we must not forget that Islam had already given us lessons and teaches the concepts regarding environmental protection and solid waste management in the right way.

After that, the system of disposal and waste management began in the then Greek cities and among the Romans the landowners were responsible for cleaning their respective areas or streets while making these things a specialty. But these things weren’t as organized and were somehow random. However, the organized system was only associated with state-sponsored events, nothing more than that. And when performing any kind of disposal, it was collected and then placed in open pits just outside the communities. But over time, the efforts were increased and the elimination was carried out far from the population area.
This very small contribution or work regarding elimination also began to decline when the Empire of Rome disappeared. Until the 14th century, scavengers were responsible for removing waste or putting it in pits, but outside the city and in 1714 the city of England contained official scavengers. And at the end of the 18th century, the American municipal system founded the first garbage center in Bonston, New York and Philadelphia. Within these systems, the wastes were still rudimentary and rudimentary, but the dumping of wastes was just astonishing by putting them in the pits along the banks of the rivers.
Developments in waste management
A mature and responsible approach to solid waste management began in the late 19th century when sealed cans were used to collect solid waste and in many parts of the United States heavy duty vehicles were used to collect and transport solid waste on fixed plots. . However, an important and valuable development was observed in the area of ​​waste management, when the city of England obtained the construction of the first waste incinerator in 1874. And at the beginning of the 20th century, 15% of the major American cities have incineration plants, However, many use earlier equipment, but the weight of disposal is the same.
Over time, technological waste management has also progressed and many other instruments have intervened between the creation and disposal of waste, such as garbage crushers, compaction trucks and pneumatic piping system have been put. in place, as the disposal of waste in open fields creates more pollution, ravages the environment and endangers the health of living things. For this, a new system has been treated, which is more advanced and protects against any inconvenience of the environment, that is to say a sanitary landfill system.
This system replaces incineration and dumping of waste in the open air, which is really a gigantic system to mitigate environmental tampering. However, the use of sanitary landfills protects and preserves the environment from the harmful effects emitted by incinerators and landfills and these landfills are well equipped. Nowadays, incinerators are also manufactured in such a form, which depletes the heat to go outside and has many air pollution control devices to meet the strict air quality. And now in modern times, solid waste management plants are being enhanced with recycling chambers and waste reduction at source.
Characteristics of solid waste
There are different types of solid waste due to their different emission and exemption sources. These wastes can come from residential houses, commercial properties, industries, institutions, etc. However, the main character and the most decisive character that will make a huge difference between them is dangerous behavior and non-dangerous nature. Hazardous waste is collected in the proper paved way and then disposed or recycled in a proper way, a little mishandling can cause huge or serious damage, so you have to be very careful and do these things in a well subordinate and technological way. These hazardous have good sources but not as much as non-hazardous ones, as they are emitted by many common sources, so for common management and at individual level, one can easily manage non-hazardous waste, if follow the procedure in a very ethics.
Non-hazardous waste, once collected, should be separated and divided into wet and dry chambers, wet waste should be broken down into a form of manure, but dry waste should be used for other purposes after recycling.
It can also contain waste and waste but waste is compostable while waste or we can say waste is recycled and then processed for other equipment as it is not hazardous so it can be recycled and then reused for other purposes. Such as waste adds about 20% of MSW in the United States to municipal solid waste. This type of waste is specifically referred to as the construction and demolition (C&D) process and is truly a process in many developed countries.
The generation of solid waste varies from country to country, as the population of the respective area has different behavior and approach to the environment, so there may be differences in the generation of solid waste. waste at each national level. Let’s take an example of different nations, because America has very little waste paper than the nations of Japan, of Europe. Or we can highlight the example of India, it has more plastic waste than others, so people’s behavior and people’s coordination with the environment vary the waste generation. (To be continued)
