In the second half of the 20th century, asbestos extraction was up to 4 Mt/year. Due to its high strength and insulation properties, this mineral was used as an additive in building materials. Over time these materials were destroyed by the process of weathering and leaching. Asbestos fibers in dust form penetrate the respiratory system causing diseases. This article proposes the binding of hazardous asbestos fibers in a polymer matrix formed from waste cooking oil. Compact materials were produced by heating catalyzed waste cooking oil and asbestos waste, and the process of obtaining these materials was optimized and their physicochemical and strength properties were determined. Oil-asbestos blocks contained sulfuric acid in a mass ratio of 0.05-0.30, being the mass of waste cooking oil, invariable mass of filling and 20% of waste cooking oil to the mass of the whole mixture. The materials were characterized by a compact structure and high hardness. The best mechanical strength above 140 N/mm was obtained for blocks with low acid to oil mass ratio ranging from 0.05 to 0.1125.

获得油块，作为管理有害石棉的一种方法。

在20世纪下半叶，石棉提取量高达4 Mt /年。由于其高强度和绝缘性能，这种矿物被用作建筑材料的添加剂。随着时间的流逝，这些材料被风化和浸出过程破坏。尘埃形式的石棉纤维渗透呼吸系统，导致疾病。本文提出了由废弃食用油形成的聚合物基质中有害石棉纤维的粘合。通过加热催化废食用油和石棉废料生产致密材料，并优化了获得这些材料的过程，并确定了其理化性质和强度性能。油石棉块所含硫酸的质量比为0.05-0.30，是废食用油的质量，填充物的总质量和全部食用油的20％。该材料的特点是结构紧凑，硬度高。对于酸与油的质量比范围从0.05到0.1125的嵌段，可获得140 N / mm以上的最佳机械强度。
