What is Recycling?
Recycling is the inclusion of wastes, which can be recycled, into the production process by transforming them into secondary raw materials through various physical and / or chemical processes. In another definition, it can be defined as the recyclable waste materials that are not used in any way and are brought back to manufacturing processes as raw materials by various recycling methods.
Purpose in recycling; It should be considered as preventing unnecessary use of resources and reducing the amount of waste waste by sorting the waste at its source. Recycling and reuse of materials such as iron, steel, copper, lead, paper, plastic, rubber, glass, electronic waste will prevent the depletion of natural resources. This situation; In order to meet the needs of countries, it will also reduce the amount of foreign currency paid for imported scrap material and save a great deal of energy used. For example, the use of used paper in paper production reduces air pollution by 74-94%, water pollution by 35%, water use by 45%, and by adding a ton of waste paper to the pulp, cutting 8 trees can be prevented.
Since the number of industrial processes in the material obtained by recycling is reduced, energy savings are achieved. In the recycling processes of metal beverage cans, the metal is directly melted and transformed into a new product. Thus, the processes applied for both the ore used for production and the purification of the mine are not required. In this way, 96% energy savings can be achieved from the recycling of an aluminum can. Similarly, the energy required for reprocessing the paper separated in solid wastes is 50% of that required for normal operations. Likewise, significant energy savings can be achieved from the recycling of glass and plastic wastes.
Recycling is an efficient economic investment in the long run. Economic problems may arise as a result of the decrease in raw materials and the rapid depletion of natural resources, and at this point, recycling will make a positive effect on the economy. It will provide new job opportunities and enable future generations to benefit from natural resources.
On the other hand, as mentioned above, one of the aims of recycling is to reduce the amount of solid waste to be disposed of, thus preventing environmental pollution to a significant extent. Decreasing the amount and volume of solid waste is a great advantage, especially for countries that do not have enough space to properly dispose of solid waste.
When these recyclable wastes are mixed with normal garbage, the secondary materials produced from these materials are much lower and there may be problems in cleaning processes. Therefore, the most important step of the recycling process is separation at source and separate collection.
The Importance of Recycling
1.It ensures the protection of our natural resources.
2.It helps us save energy.
3.It provides convenience in garbage processes by reducing the amount of waste.
4.Recycling helps us invest in the future and the economy.
Iron • Steel • Copper • Aluminum • Lead • Batteries • Paper • Plastic • Rubber • Glass • Motor oils • Waste oils • Accumulators • Vehicle tires • Concrete • X-ray films • Electronic wastes • Organic wastes
Recycling methods differ for each material:
Waste aluminum is chopped into small particles. Later, these parts are melted in large furnaces and cast aluminum is produced. In this way, waste aluminum becomes almost the same as pure aluminum and can be used in production.
With the recovery of aluminum;
• The reduction in energy consumption is 95%, air pollution is 90%, water pollution is 97%, flue gas pollutant emission is 99% and bauxite is preserved in ore.
• When one kilogram of aluminum can is recovered; The use of 8 kg bauxite mine, 4 kg chemical substance, 14 kW / hour electrical energy is preserved.
• When ten aluminum beverage cans are recovered, the electrical energy consumed by a 100 kW / h lamp in 35 hours or a TV in 30 hours is preserved.
• If aluminum is produced from one ton of used aluminum; 1300 kg of bauxite residue, 15000 liters of cooling water, 860 liters of process water, 2000 kg of CO2 and 11 kg of SO2 emissions are less.
Metal packaging wastes collected separately from domestic wastes are first separated according to material in collection and separation facilities. Here, with the help of large magnet systems, aluminum, steel etc. such materials are separated from each other. The collected packaging wastes are pressed for ease of transportation and storage. Thus, the volume is reduced. As a result of this process, metal packages are brought to the facility where they will be processed. Physical grinding is done first here. After the grinding process, it is melted in high temperature furnaces. Metal blocks are formed by pouring the melt into the mold. These metal blocks are pressed to the desired thickness. It is ready for filling after shaping suitable for all kinds of packaging such as aerosol, beverage can, paint can.
Paper is first broken into fibers in water for the preparation of paper slurry. If necessary, it is subjected to the cleaning process for foreign substances that do not contain fibers. Sodium hydroxide or sodium carbonate is used as ink separator. Then the ready-made paper fibers are used in the production of recycled paper. Waste paper cannot be recycled continuously. In every recycling, the length of the fibers becomes shorter and new paper cannot be produced without adding auxiliary substances for fiber adhesion.
When 1 ton of used paper is recycled;
• 12400 m3 of carbon dioxide, which is a greenhouse gas, can be disposed from the air.
• Continuing to produce 12400 m3 oxygen gas,
• Preservation of 17 adult trees that meet the oxygen needs of 34 people,
• 32 m3 water savings consumed by 3 families per month,
• Saving 1750 liters of fuel oil to be consumed by two families for the purpose of heating in the winter months, saving -2.4 m3 of landfill area,
• It is possible to save 4100 kW / h of electricity that 20 families will consume for a month.
Plastic wastes are first separated according to their types and recycled. Recyclable plastic wastes separated according to their types are broken into small pieces in crushing machines. Businesses can use these parts directly in the production process by mixing them with the original raw material in certain proportions. It can also be used as second class raw material by melting again and adding additives.
When the used plastics are recycled and put back into production, new coats, industrial fibers, business hat, grocery cart handles, school and workplace parts, golf and tennis equipment, garden furniture corner stones, garbage collection bins, flower pots, benches, auto spare parts, water meter box It is possible to obtain new plastic products such as buckets, carpet material and drain pipes.
Only the following products are obtained from PET recycling; carpet soles, sleeping bags, insulating material in clothes, auto parts, paint brushes, life saving pads, bags, mailboxes, picnic tables, fences, hiking boots, double compartment buckets, laser toner cartridge, straps and geotextiles ...
With Plastic Recycling;
• A seating group for 6 people can be made from 1050 recycled plastic trays,
• If a 2.5-liter plastic bottle is recycled and used in production, 6-hour 60 watt electrical energy can be saved.
• If 25 2-liter beverage bottles are recycled, you can get a plastic sweater from this material.
• A jacket can be produced from 25 used plastic bottles.
• A sleeping bag can be made from 35 2.5 liter used PET bottles.
There are three groups of substances that fall into the composition of glass. These are substances that can turn into glass, called oxides, dissolvers and stabilizers. Bottles, jars, glass cups, vases and other glass wastes are collected separately in collection boxes or where the waste is generated, and these wastes are separated according to their colors and given to recycling facilities. Here it is separated from waste and additives. Glass materials are broken and mixed into the raw material mixture and poured into melting furnaces. Broken glass is also used as concrete additive and glazing. Around 30% recycled glass is added to the glazing.
At least one in three glass packages we use is made from recycled glass. Waste glass bottles and jars are used in the production of glass packaging. Other glass types are not included in this process due to the different raw materials they contain.
The energy saved as a result of the recycling of a glass bottle is equivalent to the energy used by a 100-watt light bulb in 1 hour, a computer in 25 minutes, a television in 20 minutes, and a washing machine in 10 minutes.
Benefits of Glass Recycling
• 25% reduction in energy consumption
• 20% reduction in air pollution
• 80% reduction in mine waste
• 50% reduction in water consumption
• Protected natural resources: sand, soda, lime
Since the composite packages collected are obtained by using many materials together, the recycling process also consists of complex steps. After the grinding and separation processes, the paper and aluminum / polyethylene parts are separated from each other. The recycled paper can be used in the production of products such as tissue paper, toilet paper and corrugated cardboard after being subjected to a kind of paper recycling process. After the paper part is separated, the remaining part (Aluminum and Polyethylene / or another material) can be used as additional fuel in cement factories since its calorific values are high. It can also be recovered by burning for energy purposes. Another application is the products produced in our country under the name of yekpan. After the composite packages are trimmed and milled, a material similar to chipboard is produced by compressing in presses. The resulting product is a water and moisture resistant material that can be used in garden furniture.
