Can rock wool sandwich board be recycled

Shandong Wiskind Architectural Steel Co., LTD., has been focusing on the production and research and development of building envelope steel products for 40 years. In recent years, the company closely follows the global energy cycle application initiative, infuses environmental protection and sustainability into product innovation, and has developed a series of energy-saving building materials, which has won the national green building materials three-star evaluation certification, providing reliable product support for the energy saving of the whole life cycle of buildings.

Rockwool sandwich board is of course recyclable. The raw materials of rock wool sandwich board include natural rock, adhesive, dustproof oil and metal, etc. The rock wool products in these materials can be degraded naturally, and the metals can be recycled. According to the situation of waste rock wool, the metal and rock wool are separated by crusher first, and the waste metal is recycled and refined again. The separated rock wool is broken into fibers, pressed into blocks again, formed into blocks, and then smelted directly into the furnace to process new rock wool products. The strength and hardness of rock wool block affect the reuse quality and efficiency. Generally need to press into cylindrical and hexagonal, forming block has a certain strength, will not break, can be batch into the kiln smelting. In order to ensure the quality of the finished product, a impurity removal process should be carried out before crushing to avoid the entry of other substances.

It should be noted that some scraps and rock wool products contaminated by chemical agents should be sent to a professional waste plant for waste burial.
