a group of researchers from Pilot University of Colombia evolve slaverya technique made of guadua-bamboo, which does not exist anywhere else in the world. This 3 mm thick laminate replaces any petroleum derivative (polymer) in applications such as lamps, cell phone housings, aluminum, false ceilings, among others.

“The purpose of a slave is to guarantee a ecological transition In terms of physicality, for change petroleum derivatives For 100% local, renewable and biodegradable ingredients, And we are working to make it even cheaper than monoculture lumber,” says architect Andrés Valverde Farre, one of the leaders of the project that will soon be marketed in the country. This tells us about this development:
What is Gualam Technique?
Gualam is a sheet made of guadua-bamboo fibers which has reached a minimum thickness that does not currently exist on the market (3 mm) and which replaces injection molds for synthetic polymers and monoculture wood. Thin laminates can have applications in a variety of technical fields to replace any type of product; For example, lamps, lighting accessories and mobile device housings, among others, without the presence of raw materials derived from petroleum (polymers).
It aims to guarantee an ecological transition in terms of materiality, replacing petroleum derivatives with local, renewable and biodegradable materials.
Is this a purely Colombian development or does something similar exist in other countries?
This is a purely Colombian development (researchers from Universidad Piloto de Colombia) and there is nothing like it in other countries. Specifically, we have technical oversight in China, which are leaders in the industrial development of bamboo, and for a thickness of 3 mm they are using MDF with a surface film that imitates the finish of bamboo.
Who is the author of this development?
Andrés Valverde Farre from the Architecture Program, and Nestor Fernando Penagos from the Mechatronics Engineering Program participated; Research Group Guide and . Too innovatik,
How long did it take for them to develop?
It took two years for development and 5 years until the registration of the patent application for the invention.
What applications can it have?
Some of Gualam’s applications are in the manufacture of furniture and tableware to replace the shells of objects made from synthetic polymers and other materials such as aluminum; Architectural materials for surface finishes, such as false ceilings or envelopes, among others.
Has it already been patented? Has it been commercialized already?
The registration of the patent application has already been submitted to the superintendent of industry and commerce under registration NC2022/0005127 on April 25, we have entered into an agreement with the company Bambicandus, a company in the Quindio region, which has a role in exploitation. Has a long history. Guagua in a sustainable way, and we are pursuing industrial scaling for an accelerated commercialization with them.
What were the main challenges you faced during the development of technology?
The main challenge we faced during technological development was the need to be consistent with not using oil derivatives for which we only had colbon in the agglutination process and even in small proportions, we could not incorporate it. . , if we wanted to keep it. Theory of biodegradable materials and distribution with petroleum derivatives. And in the process of searching for an alternative binder, another innovation emerged.
What are the competitive advantages of this product compared to others in the market?
The competitive advantage over other products lies in the lack of oil derivatives, which will progressively make oil-derived materials more expensive. We are working to make it even cheaper than monoculture timber and it clearly outperforms the later segments in life cycle analysis.
