One could wonder how waste can be converted into the worthiest. But,yes,there are some ways in which various kinds of waste can be treated so that despite of getting rid of the adverse effect of waste,we can also have some beneficiary effects.
The foremost example of such a way is the ‘plastic road’. The technology of this was developed by the ‘Plastic Man’ of India Prof Rajagopalan Vasudevan. These kind of roads are made from the plastic waste and are more durable than the normal roads.
# They are twice as strong as normal roads,resistant towards water stagnation and prevent bleeding of roads.
# Pre-fabricating the road blocks makes construction 4 times faster, according to KWS.
# The roads last 3 times longer than regular asphalt roads.
# If the road is damaged for whatever reason, the damaged block can simply be replaced. No more traffic jams due to road repair.
# The damaged block can furthermore be recycled and made into a new one.
# Another merit of these roads is that they are even cheaper than the normal ones.
# Since it’s made from recycled plastic, the roads reduce the amount of plastic litter around the world.
It’s a well-known fact that plastic is a non-biodegradable material and has adverse effects, but it has become a part and parcel of our lives. In some things such as electrical wires,switch boards etc plastic has become mandatory,while we can avoid it in things such as water-bottles, coffee-cups etc. But people do prefer plastic as it is quite affordable.
Therfore we can minimize the plastic waste by these plastic roads. Every new road that’s going to be laid must be laid with plastic waste.
The ‘organic waste ‘ bags the first place amongst the waste generated by us. The best methods of treating such waste is by composting and vermi-composting. But these have some demerits like long time and bad odour.
The recent method is the ANAEROBIC DIGESTION. It’s very similar to composting. But it requires specialized tanks so that the break down takes as little as five days. In addition to producing manure, this process also creates biogas, which can be used to produce power and heat energy.
These kind of anaerobic digestion plants should be there in every mandal, if not possible in every district. For these plants to run properly,the waste should be collected and segregated properly and regularly. People should be advised to keep separate dust-bins for kitchen waste and other waste for making the segregation process easier. This also generates employment.
RECYCLING THE PAPER also makes the paper waste into the worthiest. It might sound like a strange thing. But it is proven that the non-white colour of the recycled paper relieves the eye strain.
Reusing the paper is finer than recycling it, because it takes some time. We can make decorative items, paper baskets with old newspapers.
Due to the technological revolution, E-waste(electrical waste) is being generated on a large scale. E-HOLLOW BLOCKS and E-SOLID BRICKS are innovative ways of managing the e-waste. In the E-hollow blocks,the e-waste is filled in a ready-made hollow block and in E-solid bricks e-waste is mixed with the mud-brick’s raw material.
These are used for constructing walls, compounds etc. They also minimize the raw material required for the preparation of mud
THE POO POWER:
UK researchers recently invented a toilet which works without water or electricity, two key services which are not available to a huge part of the population.
The amazing thing about that toilet is that it separates the water from the human waste, which can be used for irrigation, household washing or even as drinking water!
The human waste’s gas is converted into energy and the remaining solids can be used as fuel or fertilizers.
Through this waterless process, the toilets can provide clean sanitation to people who don’t have it – and even provide water and energy as a byproduct.
Using the waste from steel plants for making concrete:
A company named carbecrete makes cement free concrete.Cement is the main ingredient in concrete that causes CO2 emission during its production, so avoiding cement already saves CO2.
Furthermore, Carbicrete’s process actually injects CO2 into its product, making it actually a carbon dioxide negative concrete.
Carbicrete takes waste product from steel plants, and mixes it with purified CO2 in an enclosed chamber. The CO2 reacts with the compounds in the steel waste, resulting in a product that behaves like regular concrete.
Inspite of these, there are many other creative ways of waste management. In our country, students are given a lot of stupid stuff under project works. Instead of that, they should be asked to work on these kind of issues. They should be encouraged to organize awareness campaigns about waste managementin their surroundings.
It’s the responsibility of all of us to let the ‘waste’ not go waste. It should be used creatively as mentioned above.
TRANSFORM THE WASTE
INTO THE WORTHIEST
AT THE EARLIEST
