Solid waste means any garbage, refuse, residual, sludge from sewage, waste from factories, mills, commercial processes and other discarded materials from different sources. We can spot piles of waste rotting away everywhere we go, they rot and leave behind toxic discharge and foul smell. They don’t destroy our landscapes, ruin our rivers, lakes and other water bodies. Landfills are used to obscure this waste, but for how long can you bury the waste by digging holes in the ground? It takes lots of area for creating one landfill and people have to evacuate the surrounding area because of the health hazards. With incalculable metric tonnes of solid waste being produced each day it is logically impossible to create landfills incessantly or we will no longer have land to live.Clean village is no longer true because trash has overcome the rural-urban divide very successfully.
Solid Waste Management reduces or eliminates the adverse impact on the environment & human health.
A number of processes are involved in effectively managing waste . These include monitoring, collecting, transporting, processing, recycling and disposal. The quantum of waste generated varies mainly due to different lifestyles, which is directly proportional to socio economic status of the urban population.
Some treatments of solid waste include, Thermal treatment where the waste is incarcerated and converted into carbon dioxide, water vapour and ash. Also labeled Waste to Energy (WtE) method, it is a means of recovering energy from the waste.
Another process is Pyrolysis where the waste is treated in the absence of oxygen and in deficiency of air. Biological treatment methods: This involves using microorganisms to decompose the biodegradable components of waste. Landfills and open dumping is also practised on a wide scale which involves dumping waste in open areas and landfills are big craters which are filled with waste and covered.
However an effective method for waste treatment is 3Rs which is ( reduce,reuse, recycle) and also other eco friendly methods which are being created with the advancement of technology.
Solid waste has many negative and harmful impacts on the environment. Soil contamination is one of them, this waste when disposed in the land leads to emissions of toxic substances like lead etc. which leads to health hazards and chemicals that seep into soil and leave it barren.The way we dispose of waste is troubling. What is worse, in this decade alone, it would seem that waste disposal has become more careless. What we have failed to do is to put into action the ideas we believe will help us mitigate or adapt to climate change. It leads to global warming, disturbed season cycle and even disasters like flooding and clogging.
Solid waste is the breeding ground for germs and viruses which invite numerous diseases into our homes and deteriorate the state of our health and cause diseases like bronchitis, tuberculosis etc.
It also poses threat t o wildlife and their habitat as their houses are rendered unfit for living due to the waste dumped in their area. AS such ENBIO pvt. Ltd. has come up with eco friendly ways to dispose off these waste material in a more effective and less harmful manner
