Stone paper vs. pulp paper – what''s the impact of stone paper? In a previous blogpost, we explained the production process of stone paper. Now, we would like to show some figures regarding the exact resources saved when producing stone paper, as compared to traditional pulp paper.
· The mechanical method (generally used to make lowergrades of paper) is called the groundwood process, because the pulp was originally made by using huge stones to grind up logs. Nowadays, pulp is prepared by giant machines that cut,
· Paper made from stone groundwood pulp had more yellowing due to the presence of lignin, so that quality paper was still produced from rags. At the end of the 19th century a bleaching process was developed in Scandinavia, which made it possible to remove lignin out of stone
Paper production. The stock passes through one or two headboxes onto the paper machine. The paper web is formed from the head box onto the wire and dewatered through the wire primarily by the action of gravity and suction/vacuum.
Handmade paper is also prepared in laboratories to study papermaking and in paper mills to check the quality of the production process. The "handsheets" made according to TAPPI Standard T 205 [17] are circular sheets cm ( in) in diameter and are tested for paper characteristics such as brightness, strength and degree of sizing.
From building industry waste to paper! Rockstock is made from waste from the building industry. Offcuts and waste stone rock, marble and tiles are ground to recover Calcium Carbonate (CaCO3)that forms % of Rockstock RPD Paper. White waste marble at an existing quarry is the raw material to make stone paper. The basic process of Stone paper
The stone is sprayed with water to remove fibers from the pulp stone, and to prevent fiber damage due to frictiongenerated heat. The production of mechanical pulp (also called groundwood ) results in little removal of lignin content, and consequently produces paper that is not of as high a quality as other pulping methods that remove significant amounts of lignin.
If the end use required a smooth surface, papers were glazed by a worker using a smooth stone. The paper was spread out, according to Lalande, on a tanned chamois or sheepskin, and "the finisher passes the smooth stone, with considerable pressure, over both sides of the paper, almost always pushing the stone

Our paper has been copied and rebranded by many and has been called many things stone paper, limestone paper, ecostone, rock paper, xxxstone and even a ''skin'' from the earth. FiberStone® paper is the real thing paper made from natural stone specifically 80% natural calcium carbonate powder.

· The mechanical method (generally used to make lowergrades of paper) is called the groundwood process, because the pulp was originally made by using huge stones to grind up logs. Nowadays, pulp is prepared by giant machines that cut, wash, chop, beat, and blend wood, rags, or other raw materials into a soggy mass of fibers.
Papermaking, formation of a matted or felted sheet, usually of cellulose fibers, from water suspension on a wire screen. Paper is the basic material used for written communication and the dissemination of information. In addition, paper and paperboard provide materials for hundreds of
Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, waste paper, or with water and other chemical or plantbased additives, pulp is the major raw material used in papermaking and the industrial production of other paper
In the production process of stone paper, not a single tree is cut down. The paper replacement product contains no cellulose and is 100 percent Tree Free! Stone Paper is not really a real paper. However, due to its paper alike look such as its sphere of application, the product is called stone paper.
Before the industrialisation of paper production the most common fibre source was recycled fibres from used textiles, called rags. The rags were from hemp, linen and cotton. A process for removing inks from recycled paper was invented by German jurist Justus Claproth in 1774. Today this method is called was not until the introduction of wood pulp in 1843 that paper

Stone Paper Production. 1 Grind Powder Process The raw materials of stonepaper is provided in this process. After cleaning and broken, Calcite block has been grinded to lime carbonate powder (600mesh), and the average grain diameter could be 5μm8μm, It would be sent to
The Paper Making Process – How paper is made. Papermaking – Wikipedia. How paper is made – material, manufacture, making. Step by Step paper production. 1. Logging – First, wood in industrial quantities is needed, with tree trunks and logs harvested and shorn of their branches. 2.
PP/PE stone paper production completely meets environmental requirements. Except for the good waterproof property, it has the merits of insect prevention, mothproof, moistureproof, moldproof, grease proofing, light fastness, good lightadmitting quality, nontoxic, innocuity, resistance to abrasion, thermostability (no deformation under 100℃).
The global stone paper market size was estimated at USD million in 2015, and is expected to grow at a CAGR of % from 2016 to 2024. Rising demand from key application segments, low production cost, and high demand for environmentfriendly packaging materials.
Papers are made with the pulp of the woods, which is an Ecofriendly product. Paper is made through the following processes: 1) Pulping procedure will be done to separate and clean the fibers. 2) Refining procedure will be followed after pulping processes. 3) Dilution process to form a thin fiber mixture. 4) Formation of fibers on a thin screened
