Recently, there is a critical issue on crop waste management from agricultural sectors in Malaysia. Due to the rapid development in agricultural sectors, there are approximately 1.2 million tons of agricultural wastes being disposed annually in Malaysia. This kind of waste is usually eliminated by burned or decomposed and lead to the arising of some environmental issues. Regarding to environmental and sustainability awareness, concerns on the long term effect of burning crop waste have been expressed including pineapple leaves burning. Responding to this emerging issue, there are emphases on transformation of crop waste to wealth in order to create a sustainable agriculture industry. In pineapple cultivation, the pineapple leaves can be further processed to produce value-added products. Pineapple waste is no longer something that is unwanted. Recently, it is regarded as resources for economy development. Turning pineapple leaves into wealth not only makes good environmental sense, but also turns "trash" into "cash". In Malaysia, several initiatives have been done in order to extract fiber from pineapple leaves and convert into commercial products. However, the process involved in pineapple leaves fiber productions is still lag behind technologies development in this era. The proposed technology involved in sustainable pineapple leaf fibers (PALF) productions practicing the process that will reduce the environment pollution, minimize the waste, conserved energy and natural resources. This sustainable manufacturing will maximize the productions of pineapple leaf fibers and develop green environment as well as boost the economy growth.

In agricultural sector, there is an environment and technical issue during disposal process of agro waste after harvesting. Nowadays, there are some efforts being made worldwide in order to promote agricultural waste in a series of value-added products. The establishment of highperformance materials made from natural resources is a good approach towards developing sustainable agriculture sector. One of the potential fibers from agricultural waste developed in Malaysia is pineapple leaf fiber (PALF). An extensive research showed PALF have been successfully performed in textiles industry and reveal PALF immense potential in yarns productions. This work presented the new technology invented for PALF productions. The comparison of tensile properties between PALF extracted by hand scrapping and PALF M1 are evaluated. Besides that, the effect of alkaline and heat treatment towards PALF tensile properties also being studied. Obviously, the PALF extracted using PALF M1 experienced higher tensile than PALF extracted by hand scrapping. Furthermore, it was found that both treatments substantially increased PALF tensile strength. Further investigations is required in order to determine the effect of fiber properties and linear density on PALF yarn hairiness in spinning system. 

PALF (pineapple leaf fiber) is one of the abundant sources that have been used for ages to be processed as different end product. The methods to extract the fiber are abounding. However comparisons between the machines are needed to ascertain the better function of machines and whether all natural fibers can be extracted using the same exact machine. Data shown indicates that different types of methods used to extract the fibers and sometimes theoretically worked for certain types of fibers.
