Abstract Numerous researchers in the field of noise control and acoustics have found success using biomaterials to create a porous sound absorber that is both effective environmentally friendly. This paper discusses utilization fibers extracted from waste coffee husk (CH) cotton (CO) spinning industry be an alternative synthetic-based acoustic materials. The study was conducted within range 50–...

Abstract The article attempts to assess the possibility of using non-woven fabrics made waste fibers in cladding panels. For this purpose, woolen and polypropylene nonwovens were tested for mass per unit area, characteristic opening size, lengthwise crosswise elongation at maximum strength. Non-woven placed middle thickness cement gypsum boards subjected tests density, thermal conductivity coef...

Oil sorbents play a significant role in the treatment processes of oil spills, therefore, enhancing oil-water separation capacity has been charming consideration scientific researchers. To improve properties sorption and simplify process recovery, many advanced sorbent devices have projected recently. Different types materials are used as for separation, however, up to now, there is no review p...
