GS Engineering & Construction (GS E&C) is working with the Finnish bioenergy company St1 to create a new type of bioethanol from waste cassava. Cassava is a tropical plant with a tuberous root that looks like a sweet potato.

The president of GS E&C, Huh Yoon-hong, and the director of St1 Renewable Energy, Patrick Pitkanen, signed a memorandum of understanding (MOU) for “cooperation in developing next-generation bioethanol technology” on August 29 in Bangkok. Ten people from both companies were there for the MOU ceremony.

“We think that when the two companies work together, it will be the start of the next generation of businesses that use waste to make bioethanol. In the future, we will keep working to become a well-known sustainable management company in Korea by finding new ways to do business that are good for the environment and the digital world “Huh said.

If the project goes well, the local construction company says it will be the first company in the world to use cassava pulp to make bioethanol.

Most of the cassava pulp that is made when the crop is processed has been thrown away up until now, but GS E&C and St1 have decided to reuse it to make bioethanol.

St1 is a new renewable energy division of the Finnish energy company St1 Oy. It has the technology to turn cassava pulp into bioethanol. Thailand is the third-largest producer of cassava in the world, and because it has a lot of cassava pulp, which is usually thrown away after the edible part is eaten, it is seen as the best place to start a green business.

“Before, corn, sugar cane, and wheat were used as raw materials to make bioethanol. But now, this project’s way of making bioenergy from the waste of a crop that can be eaten is getting a lot of attention on the market, and cassava pulp has become the best alternative “someone from GS E&C said.
