With the evolution of technology; environmental problems, environmental pollution, industrialization & irregular urbanization are increasing. Products resulting from the use of natural resources are left unconsciously back to nature as a result of consumption. As a result, our energy resources are rapidly disappearing. Our resources are limited in nature and decrease at the end of each production process. To prevent waste of resources and to prevent the lack of energy in the future, recycling evaluation of garbage have been researched and developed for this purpose.
What is Recycling?
Recycle means that the recyclable materials, which can be recycled as a result of consumption are converted into raw material and are included in the production process by various physical and chemical methods. The purpose of recycling is to eliminate wastes from the garbage and to avoid waste of resources. While some substances can be recycled, some substances cannot be recycled.

What are recycled substances?
Materials that can be recycled; glass, paper, plastic, batteries, engine oil, aluminum, concrete, iron, organic waste, electronic waste, textile waste, wood, metal, accumulators, solvent-based wastes, etc.

What are Non-Recycled Agents?
Mirrors, optical glasses, light bulbs, fluorescent, wallpapers, oil papers, carbon papers, embroidered boxes, coated papers, silver papers, stools, household dust wastes, etc.
What are the stages of recycling?
Most packaging we consume has a recyclable symbol on it. To be easy to distinguish for recycling trash cans in most institutions and the streets. The waste battery box is separated into plastic, paper, etc. The materials collected from the source will be clean and will save water.
The substances to be recycled must pass through various stages. Recycling stages; collection, transportation, decomposition, pressing, pressed packaging waste storage and loading.
Benefits of Recycling
Recycling 1 ton of paper means saving the tree. It also saves 2583 liters of oil, 26,497 liters of water, and 2523 liters of waste. Recycles aluminum to save 95 percent of the energy needed for new aluminum production.
Recycling of aluminum can save the energy of the television we will watch for 2 hours. Recycling a ton of plastic saves 7570 liters of fuel. It protects our natural resources and prevents wastage. Reduces environmental pollution and Contributes to the economy.
Besides, many wastes can be used in many areas, for example;
Aluminum: Waste aluminum is chopped into small particles. Then these parts are melted in large furnaces and cast aluminum is produced. In this way, the waste aluminum becomes almost the same as pure aluminum and can be used in production. As a result of recycling 1 ton of metal waste, 1300 kg of raw material is saved.
Concrete: Concrete parts are collected from demolition areas and brought to the places where the crushing machines are located. After crushing, small pieces are used as gravel in new works. The fragmented concrete can also be used as a dry mortar for new concrete if it does not contain additives.
Paper: The paper is first separated into fibers in water to prepare paper sludge. If necessary, the non-fiber foreign substances are kept in the cleaning process. As an ink separator, sodium hydroxide or sodium carbonate is used. The ready-to-use paper fibers are then used in the production of recycled paper. As a result of the recycling of 1 ton of used paper waste, 16 grown pine trees, and 85 square meters of woodland areas will not be destroyed.

Plastics: Plastic wastes are separated according to their types and recycled. Recyclable plastic wastes, which are separated according to their types, are broken into small pieces in breaking machines. Enterprises can use these parts directly in certain proportions with the original raw material and use them in the production process; it can also be used as second class raw material by adding it again and adding additives. Recycling of 1-ton plastic packaging waste will save 14000 kWh energy.
Glass: Glass wastes (bottles, jars, etc.) are collected in collection boxes and these wastes are separated according to their color and given to recycling facilities. Here it is separated from waste and additives. Here, the glass is broken and the mixture is poured into the melting furnace by mixing. In this way, it is used again as a glass. In this way the glass can be recycled in an infinite loop, its structure does not deteriorate. Recycling of 1-ton glass waste saves 100 liters of gas. For
Recycling Evaluation of Garbage
Of course, there are good things to do before going down that deep. Through recycling evaluation of garbage, we can make many handicrafts that we can use in our house from the many wastes that we throw away every day. Here are a few handiworks that will reveal us, which is easy to make and easy to make.
Plastic bottles are the products we use all the time. Here are a few things we can do from the remaining plastic bottles. A small example of art that we use all the time and after a while, we find some trouble in our bags. Cones do not have much interest in what works. But it can work well for those who are interested.

Of course, these are just a few examples. You can expand this by combining with the richness of your imagination and your engineering skills, you can create very good works at very low costs, and you can make money by both recyclings the garbage and selling the products you make.
