Summary

  • Mr. Obiero, 34, says innovation is not only a smart way to tackle the threat of solid waste, it is also a way to provide decent and affordable housing in the country and in Africa by general.
  • It transforms hyacinth biomass into an alternative material to mahogany wood in construction.
  • Already, Mr. Obiero says he has patented the innovations and is bringing the eco-friendly materials to market.

While walking around, Nyawachi Obiero realized the eye sore the plastic waste represented. Water hyacinth was also another challenge he thought he could find a solution to.

Mr. Obiero finally decided that the best solution was to convert the plastic waste and water hyacinth into something useful. This is how he had the idea of ​​transforming them into raw materials for building blocks.

He has partnered with Moi University in the project which he says will go a long way in tackling pollution.

Mr. Obiero, 34, says innovation is not only a smart way to tackle the threat of solid waste, it is also a way to provide decent and affordable housing in the country and in Africa by general.

“I was motivated to come up with the innovation to tackle the effects of climate change and water hyacinth in our lakes,” says Obiero, who did an undergraduate degree in materials science at the Egerton University in 2014.

He also trained as an aeronautical engineer at Eldoret Aviation College.

“It’s the solution to the climate crisis and also supports the construction industry,” notes Mr. Obiero, who runs a green startup known as Femto Industries.

“These blocks have better qualities compared to building materials in terms of weather resistance and weight-to-volume ratio. Costs are also 55% cheaper than imported and/or mined building materials. »

The blocks, he notes, are also cost effective as they interlock, reducing the need for cement on the walls by 46%.

It transforms hyacinth biomass into an alternative material to mahogany wood in construction.

“It is stronger and more weather resistant and affordable compared to mahogany. The cost is 25% cheaper on average compared to what is on the market,” he observes.

Already, Mr. Obiero says he has patented the innovations and is bringing the eco-friendly materials to market.
