RPF recycling
YAMAZEN compresses and reduces the volume of waste plastics and paper waste to manufacture refuse paper and plastic fuel (RPF). The RPF is of stable quality, which allows ease of calorie control with formulation change, and ensures ease of handling. Therefore, it is used as fuel mainly for paper mills and steel plants. Furthermore, the use of RPF can reduce the consumption of fossil fuel, such as coal, thus making it possible to suppress the amount of CO2 emissions.
Recycling solutions business
Products with higher performance generate diversified types of waste, and the processing method of such waste varies with its size or material. In order to respond to a variety of waste, YAMAZEN offers a wide range of processing plans for proper and efficient waste disposal.
