Can you see this mountain?
No, this is not a trekking destination or a scenic hill range. This mountain stands right in our own city of Pune — a mountain of waste. And Pune is not alone. Every small and large city today has such mountains. These garbage hills symbolize one of the biggest urban challenges of our time: solid waste management.
As we talk about Energy, Environment and Sustainability, it is important to reflect on the relationship between solid waste and the environment.
Waste is generated every single day in every household. Garbage collection workers and municipal vehicles gather this waste and transport it through the city. But where does it finally go? Most of it ends up dumped on these massive garbage hills. Truck after truck climb these dumping grounds every day, continuously adding to their height. Thus, a small problem created in each household gradually turns into a gigantic city-wide environmental challenge.
Eventually, nature takes control. The waste begins to decompose, and during this process several harmful effects emerge. Foul odour spreads across nearby areas. Flies, insects, and pests multiply rapidly. Toxic liquid known as leachate is generated and slowly contaminates groundwater. The decomposition process also releases gases such as methane, which is one of the major contributors to climate change and global warming.
At the same time, materials like plastic, paper, cardboard, footwear, bags, and other non-biodegradable items continue accumulating for years, making these garbage mountains even larger. Day after day, the pollution problem keeps growing — just like the height of these waste hills.
Another major reason behind environmental degradation and climate change is our dependence on conventional sources of energy. Fuels such as petrol, diesel, coal, and natural gas create large-scale pollution when burned. Along with environmental damage, rising fuel prices, import dependency, transportation costs, and distribution expenses place a heavy economic burden on both the country and the common citizen.
Now the question arises — how is the fuel problem connected to waste management?
Interestingly, the answers to both problems are hidden within each other. In fact, a single sustainable solution can address both environmental pollution and energy scarcity. The missing link is the proper use of appropriate technology.
At present, we are only discussing urban solid waste management. The challenges related to rural waste management, pollution caused by agricultural and organic waste, energy generation from biomass, and rural employment opportunities are even larger subjects waiting to be explored.
By scientifically managing our own waste and converting it into renewable energy, we can reduce environmental damage, create cleaner cities and villages, empower farmers and common citizens, and strengthen the nation’s economy.
How can this be achieved?
That is exactly what I will be discussing in this article series.
I am beginning this journey of awareness through a series of small yet informative articles. Keep reading, sharing, and spreading awareness.
