“…Porous materials can be used to absorb oil contaminants from water [ 38 ]. Common sorbent materials include birch bark, glass wool, cork, polyurethane foam [ 114 ], aerogels, and polystyrene [ 115 ]. The major problem with these absorbents is the limited capability to separate high-viscosity oils.…”

Massive waste rock wool was generated globally and it caused substantial environmental issues such as landfill and leaching. However, reviews on the recyclability of waste rock wool are scarce. Therefore, this study presents an in-depth review of the characterization and potential usability of waste rock wool. Waste rock wool can be characterized based on its physical properties, chemical composition, and types of contaminants. The review showed that waste rock wool from the manufacturing process is more workable to be recycled for further application than the post-consumer due to its high purity. It also revealed that the pre-treatment method—comminution is vital for achieving mixture homogeneity and enhancing the properties of recycled products. The potential application of waste rock wool is reviewed with key results emphasized to demonstrate the practicality and commercial viability of each option. With a high content of chemically inert compounds such as silicon dioxide (SiO2), calcium oxide (CaO), and aluminum oxide (Al2O3) that improve fire resistance properties, waste rock wool is mainly repurposed as fillers in composite material for construction and building materials. Furthermore, waste rock wool is potentially utilized as an oil, water pollutant, and gas absorbent. To sum up, waste rock wool could be feasibly recycled as a composite material enhancer and utilized as an absorbent for a greener environment.

“…Keshavarz et al used the multi‐wall carbon nano‐tubes‐modified PU to enhance the oil adsorption ability of PU and it deduced that Langmuir isotherm was the best fitting model. Gołub et al used the porous materials to remove oil contaminants from water and the most effective in lowering the index of mineral oil while PU foam was less effective. Li et al studied the oleophilic PU foams for oil spill cleanup, and the maximum adsorption obtained was 46.98 g diesel and 41.42 g kerosene per gram of modified PU.…”

To improve the oil absorbency of caster oil-based polyurethane foam, nano-organicmontmorillonite (OMMT) was used for the additives. The aim of this study is to evaluate the oil diffusion mechanism and dispersion uniformity of OMMT modified caster oil-based polyurethane (MPU) using experiments and molecular dynamic simulation.Molecule movement and molecule trajectory of oil was investigated by molecular dynamic simulation and numerical simulation. According to the quantitative analyzing results, the diffusion model was put forward. The average diffusion coefficient of crude oil in 0, 1, 2 wt%, 4, and 6 wt% MPU is 2.4 × 10 −4 cm 2 /s, 2.6 × 10 −4 cm 2 /s, 3.0 × 10 −4 cm 2 /s, 3.2 × 10 −4 cm 2 /s, and 3.3 × 10 −4 cm 2 /s, respectively. It indicated that crude oil appeared gradient in the MPU. The optimal diffusion direction of crude oil is (0, 0, 1) crystal face, and the small particles of crude oil are easy to be adsorbed.The two-dimensional diffusion trajectory of crude oil is nonlinear. The diffusion model includes the diffusion of crude oil at the interface of oil and polyurethane, surface diffusion and pore diffusion, and pore adsorption. Furthermore, the diffusion model showed that the van der Waals force was the main reason for crude oil diffusion or adsorption. OMMT could improve the ability of oil/water separation of polyurethane.

“…The pore structure and large specific surface area provide more surface area to anchor bacterial species. The unique lamellar structure of clay mineral materials leads to special properties such as adsorption, plasticity, and ion exchange (Gołub and Piekutin, 2018; Pentyala et al., 2018; Xu et al., 2018). Various porous clay materials have been used to treat sewage including attapulgite, magnetic porous ceramsite, bentonite, clay mineral Fe(II)-montmorillonite, novel clay ceramic particles (Cheng et al., 2014; Han et al., 2019, 2013; Vinuth et al., 2015; Xu et al., 2019).…”

A novel Si–Al porous clay material W (reprocessed from ceramic waste) was used for Acidovorax sp. strain PM3 immobilization to promote the growth of strains and improve nitrogen and phosphorus removal performance in water treatment systems. The porous clay material W was characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy indicating that porous clay material W was a type of mullite with 63.52 m2/g specific surface area. After immobilization, the maximum biomass increased 2.7 times the specific growth rate and the removal rates of chemical oxygen demand (COD), ammonia (NH4+–N), and total phosphorus (TP) by the immobilized PM3 were 42.99, 29.19, and 11.76% higher than the free strain after 24 h. The Monod equation showed that the growth rate and processing speed of immobilized PM3 increased. The maximum adsorption capacities of COD and NH4+–N onto porous clay material W were 2.33 and 0.32 mg/g on the basis of Langmuir isotherm. The removal capacities of COD, NH4+–N, and TP by the immobilized PM3 were 588.24, 20.37, and 5.06 mg/l, respectively, as shown by kinetic studies. These results demonstrated that porous clay material W could improve the efficiency of microbial nitrogen and phosphorus removal, and the immobilized microorganism system could effectively treat domestic sewage. The adsorption isotherms can well describe the adsorption process. The maximum adsorption capacity of COD and NH4+–N on porous clay material W is 2.33 and 0.32 mg/g, respectively. Kinetic studies showed that the removal capacity of immobilized PM3 to COD, NH4+–N, and TP was 58.824, 20.37, and 5.06 mg/l, respectively.
