Yoshi is a suitable material for green transition

Current technology The number of biorefineries will enable the use of Yoshi for product manufacturing. Efficient harvesting of reeds also helps control nutrient content in the body of water and promote green migration.

Yoshi has great potential as a raw material for many processes aimed at highly refined final products for the international market.

Despite the expansion of growth area and quantity, industrial scale utilization is not progressing due to reasons such as underdeveloped harvesting technology.

“Lignocellulosic-based general phragmites need to be taken into account globally as part of the green transition,” he maintains. Timo SutaraBusiness Development Manager of Green Industry Park.

Suutarla was a mentor to a student working group investigating the function of Yoshi’s current harvesting methods in industrial-scale harvesting. This study was part of the Master’s program at LUT University. Current issues in the realization of technology for the circular economy.. The study collected data on the suitability of various methods and interviewed field operators.

Global population growth and rising living standards lead to a shortage of unused raw materials. The new circular economy technology will allow the use of new, underutilized material streams, such as phragmites, as raw materials. For example, textiles, plastics, adhesives, cosmetics and fuels can be manufactured from phragmites using current biorefinery technology.

“How can we retrieve this nutrient-absorbing annual straw from the waterways and deliver it to our factories at a competitive price? This is what Finland needs to become a world leader. It’s an important question for developing a new industry, “says Suutarla.

How to sell Yoshi

According to LUT research, Yoshi’s mechanical harvesting technique is negligible. All the technologies investigated are in the early stages of development. On the other hand, Yoshi has various uses. Traditionally, it has served as a material for untreated thatched roofs that does not require a highly sophisticated harvesting mechanism. Therefore, harvesting techniques are usually small and rely on adaptation to existing equipment. This inevitably leads to high harvest costs.

“Growth, weather and soil conditions make harvesting diverse and difficult,” said the Working Group. Jyri Kuitunen..

“Another important aspect is the currently lacking logistics and storage of harvested phragmites,” says another member of the group. Aysu CansuInterviewed with a representative of a local harvesting company in Kouvola, Finland.

“Currently, they don’t know how to transport and sell harvested phragmites. This is a big problem. Solving this problem can greatly improve the feasibility of the process.” She continues.

Cost-effective harvesting technology allows reeds to be the raw material for bioethanol

Yoshi will be an interesting addition to the raw material range for bioethanol production. Efficient harvesting of reeds also helps control nutrient content in the body of water and promote green migration.

Another mentor in the student research group, Janne Harjunpää Myllykosken bioetanoli Oy can reduce the need to import fossil fuels and reduce CO2 by harvesting Yoshi from the waters to eliminate nutrient spills and using Yoshi as a raw material for second-generation biofuels. I emphasize that I can do it. Emissions. However, high harvest costs are a major obstacle to the use of phragmites on an industrial scale.

The large-scale use of Yoshi for a variety of purposes will also create significant regional and international business opportunities.

“This study highlights our regional opportunities to turn the challenges of this era into opportunities. Yoshi’s innovative use gives us clear benefits in creating new businesses. We definitely need to seize the opportunity, “says the group’s third mentor. Mika Pentilla From Kouvola Innovation Oy.

This research sheds light on existing harvesting techniques and lays a solid foundation for further development. It is used, for example, to develop harvesting methods and to plan further research and project financing.

Members of the Student Working Group at LUT University were Nazila Bolourieh, Aysu Cansu, Anne Fraser-Vatto, Jyri Kuitunen and Daniel Teittinen. This group was overseen by Jutta Nuortila-Jokinen, an industry professor at LUT University.
