At the motor show in Tokyo, a consortium of 22 universities, research institutes and companies-suppliers of automotive components presented experimental car body made of cellulose. The prototype created in the project NCV (Nano Cellulose Vehicle), which aims to reduce the weight of cars by 10 percent in 2020.
Experienced in the design of the NCV is used a material called cellulose nanofibers (cellulose nanofiber or CNF) and CNF composite of plastics and resin binder. Itself nanofiber obtained by chemical-mechanical processing of wood; it is five times stronger and lighter than steel, and has a low coefficient of thermal expansion.
It is expected that its use will reduce the weight of cars and will reduce carbon dioxide emissions
Or nanofiber composites on its basis is considered as an alternative to metal parts, standard plastic and even glass.
In the future this may lead to reduction of the weight of cars by 10 percent and improve fuel economy. In addition, CNF can be used in construction and for furnish of interiors, as well as in household appliances.

Work on the new material began in 2017. This involved researchers from Kyoto University, and also experts of the companies Denso Corp, the largest supplier of automotive components for Toyota and DaikyoNishikawa Corp. According to the developers, by 2030 the price of the cellulose nanofibers will be reduced by half, but even then it will be more expensive than steel and aluminum alloys.
