‘Garbage is not a challenge, it is an opportunity to manage’ – Online Khabar

The issue of waste management should not be as complicated as it is now. We are sentient beings, and all those who emit waste are responsible for it. If we are careful, this waste is easily managed.

Problems have been around for a long time. The current style of management is only temporary. Now we have to take long-term thinking in it. Kathmandu does not have a large industrial zone. Most of the garbage emitted here comes from our homes, kitchens and consumer goods.

Chemical and non-harmful waste does not come out here. Most of us emit more fruits, vegetable peels, discarded food, noodle biscuit wrappers and plastic bags.

The main garbage problem of Kathmandu is the garbage coming out of the house. The easiest way to manage it is to separate garbage from house to house. The one who produces garbage should separate the garbage according to the nature.

If we make good use of multilayer coated biscuits, noodle plastic, we can earn income from it.

We all know that the waste from vegetables and fruits rots. Nature itself decomposes it easily. The question is where to put the decaying garbage and whether we will benefit from it or not.

At present, kausi farming is practiced in the city. If organic waste is to be put to good use, it is manure for kausi cultivation. If there is a slow decaying waste, it can be managed by mixing it with gadoola. There are other scientific methods as well.

There are other options if the ‘non-organic waste’ cannot be managed at home. Such fresh organic waste produced every day can also be managed by placing cattle in the ward or toll. Dung is excreted by cattle.

Now the organization and the company that come to pick up the garbage should decide to pick up the organic and other garbage on different days. If people separate the waste from the source, the management will be easier. But, we have to decide where to take organic waste, where to take plastic waste.

Biogas and electricity can be extracted from that dung. The best product is the manure that comes out of it, which is not inconvenient to use in the field. If the cattle raised in this way give milk, they can earn money from it. Garbage from meat shops can be disposed of by raising ducks, chickens and pigs.

The hospital can extract biogas from the saliva released during childbirth. We can also extract energy from things that are buried in the ground.

Plastics disposed of from house to house cannot be managed at home. A separate space was needed to manage such plastics. It had to be recycled using technology. This work should be done by the municipality and garbage collection organizations and companies.

Technologies such as extracting oil from plastics, making briquettes, flooring and making plastic granules are also being developed. Now you can go that way too.

At present, it is called ‘Seven-R’ policy in waste management. ‘Redesign’, ‘Reuse’ and ‘Recycle’ as well as ‘Redesign’, ‘Reformation’, ‘Rethink’ and ‘Refuse’ are also useful formulas for waste management.

You can also go on the basis of that. Some organizations are also working to make attractive plastic bags and handkerchiefs by washing the waste plastic. In one case they also turn into garbage, then briquettes can be made from them. Briquettes can be used instead of coal in brick kilns.

Now the metropolis and the municipalities should proceed with the same method. We do not produce much garbage in Kathmandu. If a big plant is set up in Kathmandu, the waste of all the cities here can be easily managed. Not all garbage will be taken to Sisdol or Bancharedanda, in Sisdol we will take the garbage that we can’t do anything about.

This is something that can be easily managed. Now, the new leadership of the Kathmandu Metropolitan City has taken the path of temporary solution, but if it is managed permanently, we can make money from garbage and provide employment. By creating a real ‘landfill site’ in Sisdol and Bancharedanda, we can develop settlements or other infrastructure in those areas in the future. Garbage is not a problem when you move forward in a planned manner with patience.

Now the organization and the company that come to pick up the garbage should decide to pick up the organic and other garbage on different days. If people separate the waste from the source, the management will be easier. But, we have to decide where to take organic waste, where to take plastic waste.

Moreover, if the metropolis brings clean plastic bags and gives incentive subsidy of Rs. However, everyone should be aware, conscious and responsible to make the waste management work successful. This campaign should proceed from the doorstep of every household.

Some countries have already reached the state of ‘zero garbage’. So far, we have only talked about organic and plastic waste. Now even electronic (e) waste is going to be a challenge among us. After the epidemic, many technologies, devices and gadgets have come in many fields including medical and educational. They will come out as garbage in no time.

We have not thought about its management. That is more in favor of ‘negative recycling’. For that, a big budget has to be spent. We have to be ‘alert’ to this. The waste management that is being produced here is not very complicated.

Now, if we want to move forward for long-term management, we have to study what kind of method and technology is needed. Let’s also look at the academic side. Let’s study how the work is going on outside.

If we move forward in this way, it will not be a big challenge, but if we manage it responsibly, it will help create opportunities. If individuals are responsible for this, then the government and the organizations and companies working in this field should also start working by making a scientific plan.
