“…Therefore, these non-wood plants, and their straw, represent an annually renewable fi bre resource available in abundant quantities in many regions all over the world. Nowadays, countries with a high use of agro residue based fi bres are India and China (Jahan et al, 2009;Leponiemi, 2008;Chandra, 1998). In European countries such as Italy, Germany, France, Spain, Greece, Hungary and Croatia, agricultural production is relatively high due to the adequate climate (Youngquist et al, 1996).…”

“…Jute: fibres obtained from the bark of the jute plants produces pulps of good quality with a yield above 60%. It has paper making properties similar to that of softwood materials [2]. Pulp from jute fibres could be used in production of increased quality.…”

“…Non-wood materials were in use for papermaking in China almost 2000 years ago until developed countries adopted the process of producing pulp and paper from wood sources. This process was invented in Germany by Friedrich Gottlob Keller in 1840 [2]. Nowadays, about 90-91% of the world's pulp and paper production is produced from wood [1].…”

The use of trees for paper production has contributed to the problem of deforestation with radical negative impact on the environment thereby causing an imbalance in the ecosystem. An increase in the demand and consumption of paper has also induced depletion of woods resources for paper production, thus resulting in limited availability of the raw materials. This work examined the use of non-woody biomasses as alternative raw materials, which are accessible and convertible into pulp and paper of the same quality as those obtained from wood.Due to the depletion of wood resources, the use of low-cost raw materials has been introduced to serve as an alternative resource for pulp and paper production [7]. The alternative resources include non-wood fibres, such as agricultural residues and annual plants, considered as valid alternative sources of cellulose for pulp and paper production [8]. Properties that make them suitable include high yielding ability, high pulping quality, good adaptation to prevailing climatic conditions and low-cost [9]. This paper reviews the pulping and paper production from non-wood biomasses, which are mostly annual crops and agricultural residues. These materials are environmentally friendly, cheap and have an unlimited availability that can meet the demand and consumption of paper in an economy. Components of plantsChemical composition of most plant leaves and grasses have been investigated. They consist of cellulose, lignin, hemicellulose, some terpenes, resins, inorganic element and fatty acids [10]. Research carried out on these plant leaves, and grasses indicate their percentage composition of cellulose ranges from 32.6 to 88% [11]. Cellulose is a polysaccharide consisting of a linear chain of several hundred to over ten thousand linked D-glucose units. Cellulose is the main component of the primary cell wall of green plants. It was first discovered in 1838 by a French chemist Anselme Payen who isolated it from plant matter and determined its chemical formula to be (C 6 H 12 O 5 )n [12]. The availability of lignin in plants serves the function of minimising the accessibility of cellulose and hemicellulose to microbial enzymes and also conferring mechanical strength by creating a cross-link with other cell wall components [11]. The application of non-wood raw materials in the pulping process has a lot of advantages such as pulping capability, fine fibres (speciality papers), high-quality bleached pulps [8].It also allows the production of pulp without an extreme increase in pollution compared to when wood raw materials are used [13]. Non-wood fibres and classificationIn recent years, the growing interest in alternative sources of raw materials for pulping and paper production other than wood has increased. According to Wisur (1993Wisur ( ), in 1989 of the raw material for pulp and paper production was obtained from non-wood biomass. The use of non-wood raw materials accounts for less than 10% of the total pulp and paper production worldwide [14]. This comprises of 44% straw, 18% bagasse...

“…However, they cannot provide the same printing paper quality as virgin wood fibers (Minor and Atalla 1992;Nazhad 2005;Hubbe et al 2007). Fibers isolated from annual agricultural crop residues present an interesting alternative raw material for pulp and paper industry because of their numerous advantages; they are economical, abundant, and renewable (Leponiemi 2008;Jahan et al 2009;Sirdach 2010). On the other hand, there are still some disadvantages related to: fiber supply (sources of fibers are harvested over a short period and therefore large storages are required, they are bulkier than wood which increases transport and storage costs); production (higher content of silica than wood makes the conventional chemical recovery system inappropriate, while appropriate production technology is not available and it may become even more expensive than equipment used for wood); demand stage (the actual size of tree-free market is unknown) of using nonwood fibers for pulp and papermaking (Roberts 1996;Chandra 1998).…”

aPaper performance qualities strongly depend on the origin of cellulose fibers. Awareness of environmental issues and sustainable development has led to the increase in the use of recycled printing papers. Recovered fibers are often used as a substitute for virgin wood fibers in the production of certain types of papers. As recovered fibers cannot provide the same quality level of paper products as virgin wood fibers, alternative sources of virgin cellulose fibers need to be identified. The aim of this research was to analyze the printability of laboratory papers made of different contents of straw pulp. Therefore, the printing papers were formed using straw pulp of three different cereal species (wheat, barley, and triticale) and mixing them with recycled newsprint in different weight ratios. The printability of these laboratory papers was analyzed by classifying dot reproduction quality based on four dot reproduction attributes. Printed dot reproduction greatly affects the quality of reproduction in graphic products, as dots are the most important element in multi-color reproduction of texts and images. It was confirmed that laboratory papers containing straw pulp provide the same or even better dot reproduction quality than laboratory control papers formed only of recycled newsprint.
