“…Nuestros resultados sugieren que las variaciones en las propiedades de los residuos de palma aceitera son consecuencia de su ubicación geográfica, y de las características del suelo como propone Anyaoha et al (2018). El N de los residuos de palma aceitera en el presente trabajo está estrechamente relacionado con la productividad y pueden ser absorbido por las plantas para su crecimiento (Uke et al, 2021). Los aniones N y P, son requeridos por las plantas para su crecimiento.…”

Background. The Peruvian Amazon has an area of 74,739 ha oil palm in 2019, which during the palm oil extraction process generates large amounts of solid agro-industrial waste (Empty Fruit Bunch [EFB] and Oil palm fiber [OPF]) which, due to not having proper management and being exposed to open sky is the cause of atmospheric, hydrological and terrestrial pollution. This problem could be seen as an opportunity to exploit agricultural soils. Objective. Determine the elemental composition and heavy metal content of the EFB and OPF in palm residues of the Peruvian Amazon. Methodology. The population was made up of 19.39 t day-1 of EFB and 12.48 t day-1 of OPF from the fruit extracted from the INDOLMA SA industry, district of Neshuya, Peru. The analyzes were carried out by UV-VIS spectrophotometry for P and K; Kjeldahl method for N; for humidity, the humidity balance - PCE Iberian was used and the potentiometer for the measurement of pH and the Atomic Adsorption Spectrophotometry (AAS) for heavy metals Cd, Pb, Cr, Ni, As and Hg. Results. The concentrations of the elemental content (NPK) did not present statistically significant differences between the variables, while the heavy metals in Cd, Ni, Cr and Pb in EFB were higher than that found for the OPF. However, it was the opposite with As, showing significant differences, while the presence of Hg was below the detection limits. Implications. Knowing the nutritional and heavy metal characteristics has the function that new sustainable technologies can be proposed using this raw material of organic origin that are adapted to the quality of its properties. Conclusions. The values indicate the good performance of the elemental content in the EFB and OPF, but the presence of heavy metals, especially Cd and Ni, is high in the studied residues.

“…Besarnya limbah biomassa yang dihasilkan dari proses replanting ini harus dimanfaatkan dengan baik. Kegunaan biomassa ini masih terbatas sebagai produksi pupuk dan kayu laminasi (Uke et al, 2021). Selain itu, limbah batang kelapa sawit yang dibiarkan membusuk akan menjadi sarang kumbang oryctes rhinoceros dan jamur ganoderma yang mengganggu tanaman muda (Susanto et al, 2013).…”

Selulosa mikrokristalin merupakan turunan dari selulosa atau selulosa yang dimodifikasi dalam skala mikro dengan ukuran panjang sekitar 10-200 µm yang bersifat kristalin. Batang kelapa sawit dapat digunakan sebagai salah satu alternatif produksi selulosa mikrokristalin. Penelitian ini bertujuan untuk mendapatkan selulosa mikrokristalin dari batang kelapa sawit dan mengetahui karakteristik setiap tahapan perlakuannya. Diperoleh selulosa mikrokristalin dengan kandungan selulosa yang berhasil ditingkatkan dari 31,11 ± 2,01% menjadi 84,35 ± 1,04%, hal ini sesuai dengan gugus puncak serapan FTIR dan seiring dengan penurunan kandungan lignin dan hemiselulosa. Analisa XRD menunjukkan terjadinya peningkatan kristalinitas dari MCC hingga 78% setelah melalui tahapan perlakuan kimia. Hasil SEM didapatkan MCC dengan panjang dan lebar sebesar 43,2 ± 19,6 µm dan 11,4 ± 8,1 µm dan menunjukkan terjadinya pemecahan komponen kompleks pada serat Raw batang kelapa sawit yang digambarkan dengan struktur dari permukaan yang menjadi lebih halus dan berbentuk fibril yang teratur. Berdasarkan hasil penelitian ini, proses delignifikasi, pemutihan, dan hidrolisis asam secara bertahap berhasil memproduksi selulosa mikrokristalin dari batang kelapa sawit.

“…25 The conventional approach for handling oil palm fibers in Malaysia is shredding into smaller chips and disposing back in the plantation field; this approach is found to cause nutrient deficiency of soil. 26 Therefore, the utilization of carbonized oil palm fibers not only reduces the production cost of the SSG photothermal material but also enables the upcycle of oil palm biowaste. Apart from the wise selection of photothermal materials, SSG performance also strongly relies on the water transport of the overall system.…”

“…Oil palm fiber, as a major byproduct of oil palm plantation, is produced in large amounts in several palm-cultivating countries such as Malaysia, Indonesia, India, and Latin American countries . The conventional approach for handling oil palm fibers in Malaysia is shredding into smaller chips and disposing back in the plantation field; this approach is found to cause nutrient deficiency of soil . Therefore, the utilization of carbonized oil palm fibers not only reduces the production cost of the SSG photothermal material but also enables the upcycle of oil palm biowaste.…”

Solar steam generation (SSG) has been proposed in the recent years as one of the countermeasures for solving the increasing risk of water scarcity on a global scale. SSG outshines conventional water treatment technologies with solar energy being its primary driving energy as well as its relatively simple system design. Nevertheless, challenges have been addressed for SSG, particularly the low efficiency of steam generation and dubious economic feasibility. In this study, a solar evaporator consisting of lowtemperature carbonized oil palm fibers with integration of polydopamine is used to construct a biomass-based solar evaporator. Owing to the synergistic effect of the wide solar absorption spectrum of the carbonized fiber and highly hydrophilic characteristics of polydopamine, a water evaporation rate of 1.637 kg m −2 h −1 is achieved under 1 sun irradiation. To demonstrate the ability of the as-designed system for water treatment applications, actual lake water and seawater are employed as water reservoirs, and the water purification effect is assessed in terms of total dissolved solids and salinity. This biomassderived evaporator offers a design rationale for cost-effective steam generation via biomass waste upcycling of the oil palm industry, which is advantageous for the scalable setup of the system in water-scarce, impoverished area.
