Due to the large amount of recycling by enterprises, white garbage has become a shortage of materials in the Yinchuan waste recycling market. According to statistics, at present, there are more than 30 enterprises that recycle white waste in Ningxia. In the past, waste plastic foam worthless was worth rising in the past two years. From RMB 2/kg, it has now risen to 1 kg and reached RMB 3. 3.8 yuan/kg.
Due to the lack of waste plastic foam materials, several companies stopped production from time to time. Only Yinchuan Lightweight Panelboard Factory recycles more than 50 tons of waste plastic foam each year. This factory obtained composite lightweight wallboard and composite high-efficiency perlite insulation board. Both national patent products are produced from waste plastic foams.
