Now Waste bottles to replace bricks for construction

Ever wonder where all the empty plastic bottles of cold drinks etc. go after we throw them out from our house? Even the kabaadi walas don’t want to pick them up as they are not recycled and just end in landfills, increasing the non-decomposable waste which is affecting the environment of our cities.

But now the Students and Faculty of Civil Engineering department at Quest Group of Institutions have found a unique solution to use these unwanted empty plastic bottles. With their research they have used these bottles instead of bricks in construction. As a pilot project they have created a seating for the students in the campus using plastic waste bottles. That means no bricks are used in this structure.  This project was a sample testing to see the strength and cost effectiveness of the waste plastic bottles in construction and the results have been encouraging.

Giving details of the project the Er. Himanshu Sharma and Er. Varun Awasthi, the faculty members who guided the students to take up this project said “Yes, it is difficult to think of a pet bottle as a brick. But a sand-filled bottle is 20 times stronger than a brick. Strength of brick is 3kg/N whereas the strength of a sand filled bottle is 75 Kg/N and whatever you can do with a bricks you can do with a bottle too.”

This is a unique innovation which besides being eco-friendly; offers many advantages as compared to the construction using bricks. Giving details the students Aashish Virdi said

  1. First of all we can reuse the plastic bottles which mostly end up in landfills and are becoming a big threat to the ecology of our cities.
  2. Non-usage of bricks reduces CO2  emissions (bricks need to be baked there by release a large amount of CO2 into the air).
  3. The design looks unique and being bio-climatic will help in reducing power consumption.
  4. Low cost – You know how much a waste bottle costs! Absolutely nothing. The cost after filling sand is almost half of that of a brick.
  5. Non-Brittle – (Unlike bricks), Absorbs abrupt shock loads – Since they are not brittle, there can take up heavy, Green Construction. Not to mention the very attractive benefit of being bullet-proof of which comes in handy in high security regions and bunkers etc.
  6. Good insulation – The scorching heat from the sun is a constant problem with existing structures but all the sand inside these bottles provides very ideal insulation for its occupants.

Giving further details of the project the students Amir Rana said “We used 1170 pet bottles to make a seating. The cost of the pet bottle is far less than the bricks. Unlike “traditional” bricks, bottles are not burnt, a process which uses a lot of firewood and contributes to deforestation. 5 bag of cement, 1521 kg sand, gravel2 kg,chicken mesh, 310 m nylon rope,1170 plastic bottle filled with dry sand, waste tiles, 4 kg white cement and 150 ml stainer were used to make the complete project. The project is totally economical and less construction material was used.


The cost of this construction can reduce 33% cost of house made of concrete and bricks. The total cost of the project was Rs. 6200 whereas if the project was to be made with bricks the cost would be as much high as 10000.The cost of each brick is 5.25 Rs whereas the cost of one sand filled bottle is 2.50 Rs.

The project was started on 7 Oct 2013 and was completed on 12 Nov 2013. The project was made by Civil Engineering students of 7th semester of Quest Infosys Group Of Institution. The students who made the terrific project are Ashish Virdi, Amit Rana, Amit Kumar, Rajat Garg, Naveen Rana and Amit Gautam.


Mr. D. S Sekhon, Chairman of Quest Group of Institutions lauded the effort of the students and faculty and said Quest Group is encouraging students to constantly think about the finding practical technology solutions to the problems being faced by the society. He said the Quest Group is only institution in the region to have projects based learning methodology, which develops habit of gaining practical knowledge rather than cramming the theory of the subject.
