Industrial waste ng coal power plants, pwedeng gawing eco-friendly construction materials

8 months ago

Renewable energy pa rin ang goal para labanan ang climate change. Pero habang malaking porsyento pa rin ng bansa ang nakaasa sa coal energy, may solusyong dinevelop ang ilang researcher para ang industrial waste from using coal... mapakinabangan bilang -- construction materials!?!? Let's change the game and make our own geopolymer brick!

00:00Renewable energy is still the goal to fight climate change, but while a large percentage of the country still relies on coal energy,

00:18some researchers have developed a solution for industrial waste from using coal to be used as construction materials.

00:27Let's change the game and make our own geopolymer brick.

00:32Electricity powered by everything.

00:36But there's no electricity if there's no proper source.

00:40But where does the electricity come from in the country?

00:4360% of our power supply comes from coal-fired power plants.

00:48Coal is burned in power plants.

00:51It's mixed with water to produce high-pressurized steam that circulates in turbines that generate electricity.

01:00But what does this electricity produce?

01:02It's a substitute for carbon emissions caused by climate change,

01:06as well as the residual industrial waste of coal fly ash.

01:12For the second problem, the G-MATRIX group has a solution.

01:16Led by Dr. Michael Promentilla of Dallas Hall University,

01:20coal fly ash is upcycled into construction material known as geopolymer bricks.

01:27This is their waste.

01:30There are toxic components in this fly ash that are not good for our environment.

01:37These are also more eco-friendly compared to cement that has a high carbon footprint.

01:44It has a lower carbon footprint by 80%.

01:48Talk about hitting two birds with one brick.

01:53This is one of our examples of geopolymer bricks.

01:58We have Engineer Aithan with us today.

02:01He will walk us through everything.

02:03We need to wear a mask first. Safety first.

02:06This came from a power plant in the city.

02:09It was thrown away, but now they have seen the potential of active materials in making cementitious materials.

02:18First, the dry materials were mixed.

02:22Coal fly ash,

02:25mine silt,

02:26an industrial waste of mining,

02:29and sand.

02:31Wet materials were prepared

02:35and mixed with abaca fiber.

02:39Abaca fiber is used for reinforcement.

02:43To hold it together.

02:45Aside from being eco-friendly, geopolymer bricks are also fire-resistant and acid-resistant.

02:51And in their testing, the cement is even stronger.

02:55They have tried using it as pavers in the DLSU Laguna Campus.

03:01We are able to address the problem of climate change.

03:04Now, we are developing technology to make it cheaper.

03:09While a large percentage of our electricity depends on coal energy,

03:14these innovations are a big deal to reduce the negative effects of traditional energy.

03:22For GMA Integrated News, I am Martin Avier,

03:25Changing the Game!
