The recycling method to be applied according to the properties of each material also varies. For example, the paper is recycled as follows:
Professor Dr. Karaosmanoğlu wastes, “Wastes are the raw materials of the green economy, which is the national wealth of our country.” he describes. Recyclable waste in the world; It is considered as the seventh natural resource after air, water, coal, oil, natural gas and minerals. The Global Recycling Foundation celebrated "March 18th World Recycling Day" for the first time this year to draw attention to these valuable resources in the trash.
The paper is first separated into its fibers in water for the preparation of the paper slurry. If necessary, it is cleaned for foreign matter without fiber. As the ink separator, sodium hydroxide or sodium carbonate is used. Then ready-made paper fibers are used in recycled paper production. Waste paper cannot be recycled continuously. With each recovery, the length of the fibers is shortened and new paper cannot be produced without adding adjuvants to the fibers to adhere.
When 1 ton of used paper is recycled;
• 12400 m3 of greenhouse gas, carbon dioxide, can be removed from the air.
• Continuing to produce 12400 m3 of oxygen gas,
• Protection of 17 adult trees that provide oxygen needs of 34 people,
• 32 m3 of water savings consumed by 3 families per month,
• Saving 1750 liters of fuel oil, which will be consumed by two families for the purpose of warming in the winter months, saving from 2,4 m3 of garbage storage space,
• It is possible to save 4100 kW / h of electrical energy that 20 families will consume for a month.
In general, recycling processes can be divided into four stages:
1- Separation at Source: Recyclable wastes are collected from the garbage where they are formed and collected.
2- Classification: Wastes collected separately at the source are classified on the basis of glass, metal-plastic and paper.
3- Evaluation: Waste returns to the economy as a new material by undergoing physical and chemical changes.
4- Bringing the New Product to the Economy: The recycled product is offered as a new material.
