Indian Railways to Make Bricks from Waste Soil & Buy Back Plastic Bottles Soon!

Always under scrutiny and immense pressure to perform-the Indian Railways also watches out to make sure its carbon footprint is as minimal as can be. In the process, they even manage to pull off cost savings and reduce the impact on the environment.

Whether it is the Guwahati station that runs entirely on solar power or the solar-powered locomotive, solar energy is being used effectively by the Railways.

Other green initiatives by the Railways include the introduction of plates made of fibre, instead of plastic, and the implementation of bio-toilets in trains.

Usually, the Railways buys traditional bricks from factories and transports them to the site which turns out to be a costly affair. Experiments conducted by NIT Silchar in their lab led to a successful formula–the conversion of unused soil into bricks.

A Saibaba, Chief Engineer, Construction, Northeast Frontier Railway,in charge of the Jiribam-Imphal line, shares that the college carried out numerous studies. They found that the mixture of the local soil, with small quantities of cement and other locally available ingredients, yields strong, durable bricks, when subject to high pressure.

The national transporter wants to curb pollution and cut costs. The above process allows them to produce around 3,500 bricks every eight hours. The blocks are then used for various construction and maintenance works of the Railways, like pitching of slopes, building embankment staircases and drain-linings.

Saibaba sees this as a multi-purpose solution. This is why. Construction of the railway lines, through hilly terrain, ends up dislodging and excavating a lot of soil that can’t be dumped in streams and rivers as many villagers depend on the water bodies. Making bricks out of it solves the issue of excess soil and potential water pollution.
