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 |          　　公开资料显示，任羽中生于1980年1月，四川资阳人。

C | 2025年9月，官方通报其主动投案，接受审查调查。12月，中央纪委国家监委通报其被开除党籍和公职。他被指“毫无纪法底线，公器私用，‘靠校吃校’，搞权钱交易”等。         　　经审理查明，2006年至2025年，任羽中利用担任北京大学党委政策研究室副主任、主任，北京大学人事部部长，北京大学党委宣传部部长，北京大学党委常委、副校长等职务上的便利以及职权、地位形成的便利条件，为相关单位和个人在教育培训、升学就业等事项上提供帮助，非法收受财物共计折合人民币3195万余元。

D |                         　　法院认为，任羽中的行为构成受贿罪，受贿数额特别巨大，应依法惩处。鉴于任羽中自动投案，如实供述自己的罪行，构成自首；主动交代办案机关尚未掌握的大部分受贿事实；认罪悔罪，积极退赃，受贿赃款赃物已全部追缴，依法可以对其减轻处罚。

E | 法庭遂作出上述判决。

F |          　　据悉，丹东市中级人民法院于今年6月5日公开开庭审理了该案。任羽中当庭表示认罪悔罪。
