Quarrying and processing of granite produce large amounts of waste residues. Besides being a loss of resources, improper disposal of these wastes results in pollution of the soil, water and air around the dumpsites. The main components of granite waste are quartz, feldspars and a small amount of biotite. Due to its hard and dense texture, high strength, corrosion resistance and wear resistance, granite waste may be recycled into building materials, composite materials and fine ceramics, effectively improving their mechanical properties and durability. By using the flotation process, high value-added products such as potash feldspar and albite may be retrieved from granite waste. Also, granite waste has the potential for application in soil remediation and sewage treatment. This review presents recent advances in granite waste reutilization, and points out the problems associated with its use, and the related countermeasures, indicating the scale of high value-added reutilization of granite waste.

“…The high oil absorption of kapok fiber is due to the waxy nature of the fiber surface [17], while its absorption of water is due to its thin cell wall, wide lumen, and porosity of more than 80% [18,19]. The oil absorption ability of the fiber can be removed by changing the surface characteristics through chemical treatment with acid or alkaline [14,[20][21][22]. Alkali treatment is mostly expected to decompose lignin and damage cell structure, which can further reduce fiber porosity and water absorption.…”

This research reports the reduction of water absorption and density increase of kapok fibers from production centers in Pati, Indonesia. Kapok fiber was treated with two solvents, hexane and NaOH solution at room temperature. The NaOH solution was used in five different concentrations; 3.5, 7, 10.5, 14, and 17.5%. Fiber morphology, water absorption, density, and weight loss were determined. Results indicated that the average diameter and fiber length obtained was 70.97 µm and 2.3 cm, while its cellulose and lignin contents were 55.69% and 20.56%, respectively. Furthermore, there was no significant difference between treating kapok fiber with hexane and with NaOH solution. The 17.5% NaOH solution treatment reduced water absorption, increased density, and reduced weight losses by 55.98%, 255.55%, and 25.58%, respectively.

“…The natural fibers still need to be improved in terms of their mechanical properties, water resistance, and production process [13,14]. Various methods have been used in producing natural fibers for industrial purposes including alkaline processes [15,16,17,18]. These alkali processes have been used for a variety of fibers such as hemp, jute, coir, and ramie but still involve heat treatment and excessive use of many chemicals [14,19].…”

“…In addition, natural fibers provide a healthier environmental impact because greenhouse pollution can be reduced [14,15]. Another reason is that natural fibers have good mechanical properties, abundant supply, heat resistant, resistant to insects, has good water absorption, abrasion resistance and easy to modify their chemical structure [17,18].…”

In line with economic growth, material requirements in the industrial sector will increase. Industries are required to use materials that are safe for human health, environmentally friendly and utilize local raw materials. Currently, industries in general still use synthetic materials based on petroleum residues that contain many hazardous chemicals. Therefore, natural fiber has the potential to be used as a substitute for synthetic materials, especially in Indonesia which is rich in natural fibers resources. This will have an impact on the socio-economy of the local community so that it can grow the rural economic sector. Natural fibers have high economic value that can be used for various raw material needs for strategic industries. A good natural fiber processing mechanism will produce products that can be marketed globally with guaranteed product quality. This research analyzes the effect of alkali treatment of ramie, sugar palm and coir fiber on the increase in mechanical properties of the fiber. The mechanical properties were analyzed through tensile strength testing of single fiber according to ASTM D3822 standard using a textechno favigraph machine. In addition, this research is supported by data from thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The results showed that the fibers that had been given an alkali treatment had better mechanical properties compared to untreated fibers. Increased tensile strength of fibers was observec after being treated with alkali for ramie 81%, sugar palm 52% and coir 56%. The advantage of this alkaline treatment method is that no heating is involved and the treatment procedures are more practical compared to other methods.
