Paper recycling is the process of turning waste paper into new paper products such as newspaper, corrugated boxes, tissue products and egg boxes etc. With population growth and technological developments, paper consumption rate is increasing rapidly. For this reason, recovery rate of waste paper, which is cheaper than wood cellulose and important i...

... Table 5 below, the amounts of wood, water and electrical energy required to produce 1 ton of paper from wood and waste paper are given. According to this table, 110% more wood raw material, about 13 times more water and 1.5 times more electricity will be harmed around the environment to produce first quality paper instead of waste paper (CEKUL, 2002). ...

... The waste paper is economically more preferable. Recycling of waste paper is both environmentally friendly and less costly than pulping from wood and annual plant [2,3]. One of the most suitable waste paper recycling is to produce paper of the same class from the used waste paper class. ...
This study aimed to evaluate eggshell wastes, which have the potential to turn into high value-added products in paper industry. Membrane-removed eggshell wastes were subjected to certain processes of washing, drying, grinding, and sieving. The final product of eggshell calcium carbonate (ECC) was used in office paper production as filler, and its possible effect on physical and optical properties of papers was investigated. Mixed office wastes were turned pulp using as raw material of office paper production. Moreover, the effects of ECC was compared with the use of industrial calcium carbonates of ground (GCC) and precipitated (PCC) forms as filler. Breaking lengths of the papers were shown to reduce up to 65.2, 76.6, and 64.1% by a 30% usage of GCC, PCC, and ECC fillers, respectively. PCC and GCC were more effective in improved optical properties of papers than ECC. The brightness values were measured to be 96.8, 98.4, and 93.1 ISO% with a 30% dosage of GCC, PCC, and ECC fillers, respectively. These results suggested that ECC can be used as filler in paper industry.
