“…This waste can be categorized into two types: waste from harvesting and replanting activity in plantation fields and waste from the milling process to obtain palm oil. Numerous studies on utilization of milling waste (oil palm fiber, shell, and empty fruit bunches) have been conducted for energy applications [1][2][3], pulp and papermaking [4][5][6], bioadsorbents [7][8][9][10], construction materials [11,12], and biocomposites [13][14][15]. However, most of the milling waste is fully utilized by the palm oil industry either as an additional energy source (oil palm fiber and shell) or as fertilizer (empty fruit bunches).…”

In this study, upgrading of agricultural waste, in the form of oil palm fronds and trunks, into solid biofuel was investigated using hydrothermal treatment. A slurry of 300 mL of water and 30 g of material was treated in a 500-mL batch autoclave equipped with stirrer, thermometer, and pressure sensor. Experiments were conducted in the temperature range 200-350°C at an initial pressure of 2.0 MPa. The slurry was gradually heated to the target temperature and held for a further 30 min. Approximately 35-65% of the original material was recovered as a solid product with favorable solid fuel characteristics. The gross calorific value ranged from 19.9 to 29.7 MJ/kg and the equilibrium moisture content was 7.6-4.5 wt%. The carbon content varied from 51.4 to 78.5 wt% and the oxygen content was 42.1-16.1 wt% after upgrading. Changes in the solid composition and carbon functional groups following upgrading were identified by FTIR and 13 C NMR. In addition, analyses on the liquid product (by GC-MS) and the gas product (by GC) were carried out to clarify the decomposition behavior of material.

“…Their presence can cause disadvantageous changes in paper as it ages and is exposed to mould, high relative humidity, light, and pollution or/ and some conservation treatments (e.g., oxidative and reduction bleaching) (Leponiemi et al, 2010;Sridach, 2010;McKean et al, 1997). From all nutrients, Si is the most damaging element in the raw material for pulping, because it complicates the recovery of chemicals, wears out the installations of paper factories and can affect the paper quality (Saijonkari-Pahkala, 2001; Gonzalez et al, 2008;Sotannde et al, 2014 ). According to gained results of straw chemical composition analysis (Table 3), it could be concluded that barley straw contains the highest concentration of all analysed microelements.…”

The procedure of holocellulose content determination in non-wood plant raw materials was developed. The strength properties of pulp obtained from sunflower stalks by neutral-sulphite, soda, alkaline sulphiteanthraquinone-ethanol IntroductionLiving standards improvement requires increase in quality and quantity of consumer goods, in particular paper and paperboard. To produce them it is necessary to increase the volumes of primary pulps. For the countries with limited free timber resources non-wood plant raw materials are used in order to increase pulp and paper production [1][2][3]. Non-wood plant raw materials also can be applied as an effective alternative to constantly decreasing forest resources in different regions. In countries with developed agriculture millions tones of by-products suitable for obtaining pulp are produced by cereal and technical crops treatment. Potential world resources of non-wood plant raw materials exceed 2.5 billion tons per year [4] and renew annually. Using non-wood plant raw materials in pulp and paper industry is beneficial in terms of environmental and socio-economic aspects.
