Tiles from eggshells?

18.03.2010
Soon folks, we will be walking and running on eggshells, so do not throw them away.

Five scientists, Rassimi Abdul Ghani, Mohd Hanafiah Abidin, Ahmad Zafir Romli, Mohd Hariz Kamarudin, Zaleha Afandi and Muhamad Faizal Abd Halim of the Institute Of Science, Uitm, Malaysia are turning one of the world’s oldest waste into useful flooring materials. They made tiles from eggshells.

Naming the tiles EPoSTi, they made composite tiles by combining polymers and chicken eggshells, an innovation from domestic waste. Explaining their work in an expo, the use of eggshells in micro size will increase the rigidity and stiffness of the composite, making it a suitable flooring material. This is due to the nature of eggshells which can be used as rigid particulate fillers of the tiles. The combination offers excellent impact resistance, as it is able to withstand force applied to it. In short, it is durable.

EPoSTi is also suitable for underwater flooring. It is also durable as when tested in labs, they were found to be stable when subjected to thermal testing. The eggshells by nature can withstand temperatures of up to 750 Degrees Celcius, thus it passed the thermal testing easily. This feature guarantees safety against high temperature thus can be practical in hot climate countries.

Another benefit of EPoSTi is that it is suitable for any decorating purposes, as it can be designed according to one's taste. It fulfils almost all specifications for flooring materials and offers another alternative in house decor at an affordable price. The tiles can be sold cheaper.

Another thing, inventing tiles from eggshells, otherwise seen as waste, can reduce headache of clogged drains, waste treatment, odour emission, thus cleaner environment have we.

Eggshell is a by-product which contains about 94% of calcium carbonate by weight which is easily obtained due to heavy consumption of egg in food industry. For example China, the world number one egg producer, has boosted output 67.8% over the past decades, thus a rich source of potential natural filler for EPoSTi. A good news for the tiles industry.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
