A Filipino architect has created what he claims is one the world's cheapest and most eco-friendly green building blocks using the humble toilet roll as one of its core ingredients.

Eddie Urcia, a Filipino-born architect based out of Brunei, claims his new Easy-Block has potential to create major waves in the international green building sector.

“I have invented a cheap and innovative composite block that will revolutionize the construction industry globally,” he said.

The Easy-Block is produced using a mixture of cement and the cardboard tubes used as the core for toilet paper rolls, at a cost 30 to 50 per cent cheaper than traditional hollow blocks.

According to Urcia, laboratory tests have proven that in addition to their low cost, Easy-Blocks could well surpass their conventional peers in terms of reliability and strength. The Easy-Block possesses a pounds-force per square inch (psi) strength at least four times greater than that of a standard sandcrete hollow block, at 21,660 psi compared to 4,800 psi for the traditional building material.

Urcia, a senior partner with architecture firm Urcia and Fang, is not shy about touting the merits and virtues of his new invention.

“My latest invention is intended to compete with bricks and hollow blocks. It is easier to install and manufacture…it is cheaper and better in quality,” he said. “(It) can be used as external walls, interior partitions, flooring, finish ceiling and roofing.”

According to Urcia, the block is suited for all climate conditions due to the insulating properties provided by the hollow spaces at the centre of the cardboard toilet roll cores.

“It is an all-weather product, useful in hot or cold countries because of its remarkable insulation,” he said.

Urcia has already commenced production of the blocks in several factories in the Philippines and is promoting their usage for low cost housing projects.

This is not the first distinctive or unusual invention by the architect, who previously won an award from the Filipino government for the invention of the world’s fastest bicycle, which had 48 gear combinations.
