Ko Il Yong, deputy director of the institute, told KCNA:

On the basis of analysis of rational indexes of crushed bio-materials, the institute has set up the production processes for the fuel.

It also made stoves for the fuel.

The fuel's heat value is more than 4,000kcal/kg.

500kg of the fuel are tantamount to 1 tonne of coal.

The fuel is increasingly gaining popularity among users.

As substitute for electricity and coal, it gives no adverse effect on ecological environment.
