The drone has completed multiple test flights, China Central Television (CCTV) News reported.
Long Bamboo, a company based in East China's Fujian Province, developed the technique that preserves the bamboo's tough outer layer and allows different parts with different densities of the material to be used according to their properties, improving its overall performance.
In the past, the outer skin of bamboo was often treated as leftover material and eventually burned into low-value bamboo charcoal.
According to a company release in February, bamboo-based composites now make up more than 25 percent of the entire drone, while its fuselage skin is made entirely from the company's own high-performance bamboo composite material.
The bamboo-based material also offers a major cost advantage, costing only about one-quarter to one-tenth as much as aviation-grade carbon fiber. After the drone is retired, the material can naturally degrade, allowing it to effectively "come from nature and return to nature."
The team spent four years building data models, upgrading equipment and refining the material. The resulting drone has a wingspan of more than 2.5 meters but weighs only about 7 kilograms, and has already completed multiple test flights, according to CCTV News.
Bamboo was traditionally used mainly in products such as tableware and furniture. Now, however, the material is finding its way into a wider range of industrial applications. Bamboo fiber is being used in automobile interiors, while bamboo-based materials are also being explored as possible substitutes for plastics, glass fiber and carbon fiber in some applications. 
China has the world's largest bamboo resource base, with about 7.56 million hectares of bamboo forests nationwide. The country also ranks among the world leaders in bamboo resources, bamboo cultivation technologies and the development and utilization of bamboo materials, per CCTV News.

B |     Aditya Dhar's Dhurandhar, starring Ranveer Singh, is set for release in theaters tomorrow. While the film has been amongst the talks, some individuals have expressed concerns about the level of violence shown. Also, there has been a lot of negative sentiment surrounding the film before its release. In response to this, Aditya Dhar's wife, actress Yami Gautam, has publicly addressed the ongoing trend of paid PR.           On her Instagram, Yami wrote a detailed note describing the paid PR trend as "a plague that will affect the future." She started with, “There is something I’ve been wanting to express for a really long time. I feel today is that day, & I must. This so-called trend of giving money, in the disguise of marketing a film, to ensure good ‘hype’ for a film is created, or else ‘they’ will continuously write negative things (even before the film is released), until you pay ‘them’ money, feels nothing but kind of extortion. Just because this arrangement is accessible to anyone, whether to ‘hype’ a film or spread negativity against another actor/a film, is a plague that is going to affect the future of our industry in a big way.”                                                                 View this post on Instagram          A post shared by Yami Gautam Dhar (@yamigautam)               She further added, “Unfortunately, if anyone feels it’s harmless & let’s do it because it’s the new ‘normal,’ they are mistaken. This monster of a ‘trend’ is eventually going to bite everyone. If the truth is exposed about a million things under the garb of who & what ‘success’ is over the past 5 years especially, unfortunately, it’s not going to be a pretty picture for many. In South, no one can dare do such things because the industry stands united on a lot of fronts. I urge our esteemed producers, directors & actors to come together in order to arrest this termite of a culture at this stage itself & discourage it.”           Yami Gautam concluded her note by requesting everyone to not “kill the joy of filmmaking & presenting it to the world & letting the audience decide what they feel.” She attached this note with a comment that included “#Dhurandhar #SeeYouInCinemasTom."'Also Read: Emraan Hashmi and Yami Gautam’s HAQ Screens to a Packed House & Applause at IFFI 2025。
