By Muhammad Athar Haider Multan A university has made plastic eco-friendly interlocking bricks for its final year project, which it says will bring the construction cost of a three-marla house up to Rs.7 lakh.
Athar told Independent Urdu that he studied architecture from the Institute of Engineering and Technology and for his final year project of his degree, he made eco-friendly plastic interlocking bricks.
He said that the biggest advantage of making interlock bricks is that ‘the construction can be completed quickly.
‘This technique does not use any cement or binding agent, which reduces its cost.’
Athar said: ‘Interlock bricks have four sides. Two outwards and two inwards. The outward facing sides fit into the top and front side and the inward sides fit back to back.’
He further said that keeping in view the current problems of Pakistan, especially the mismanagement of plastic waste, he has taken this as an environment-friendly initiative. Plastic waste thought of turning it into an interlocking material and developed bricks and construction techniques from it.
According to Athar: ‘First we tested it. In which material was taken from the market, which was becoming very expensive. Then we collected it within our university. Then put it in a machine insulator and melt it. After that, the material was prepared by pouring it into molds.
‘We developed a small-sized machine that mixes this material with sand. When we started experimenting with it, we understood the properties of different types of plastics. Some are hard plastic and some are soft plastic. We had to get both its strength and shape. It was a big challenge for us, but we achieved it after a year and a half of hard work.’

He further informed that these bricks are with interlocking technique, which does not require any cement or binding agent.
‘This allows houses to be built faster and uses more plastic waste, which reduces environmental pollution.’
Athar said that ‘according to the lab testing of these bricks, they are 1.5 times stronger than normal bricks and also lighter in weight. A brick weighs about 1.7 kg.’
Athar said that ‘with this technique, a three-marla house can be built for around Rs.
Athar Haider is keen to use these bricks on a large scale.
He said: ‘Our projects have different phases. In the first phase we introduced the material by exhibiting it. In the second step, we will build a house on a practical level and present it as an example. Our future plan is to use this technique on a large scale to benefit the common man and solve Pakistan’s waste management problem.’
