Pollution is one of the major issues in the world. The increase in human population, and landfill rising and expanding day by day, is leading to increase in plastic waste all over the world, which accumulate in rivers, oceans and drinking water.

A Colombian company, Conceptos Plasticos, has come up with the solution to this problem by recycling plastic into LEGO-like building blocks that families can use to construct their homes.

Conceptos Plasticos transforms plastic and rubber waste into an alternative construction material for housing. The plastic waste is melted and poured into a mould to produce plastic blocks that work like LEGO pieces. The materials contain additive that makes them resistant to fire, and since the structure is plastic-based, it can also withstand earthquakes. The LEGO-like building blocks are easy to assemble and pocket-friendly.

The Conceptos Plasticos model home is divided into two bedrooms, a bathroom, a living room, dining room and kitchen. It can be assembled in only five days by four people who need not to have any previous experience. The price is very reasonable – only $130 per square meter for 40 square meter home, that is around $5200.

"In Bogota alone, approximately 750 tons of plastic waste is thrown into the landfill site of which only 100 are being recycled. We are making 100 homes out of the plastic in Dona Juana (the city's landfill site), giving value to something that has no market."

-says Oscar Andres Mendez, the owner of the company.
