Recycling

We can make new things from old things.

We can recycle glass and paper. We can recycle metal and plastic too. We can even recycle old tires.

First, people pick up the old items. They are sorted and cleaned. Then, they are turned into new materials.

This helps the Earth stay healthy. It saves energy and keeps the air clean. It also saves our trees.

Recycling is a great way to help our world.

Recycling is a way to make new things from old ones.

It turns waste into new materials and objects. This can even include getting power from waste.

Recycling helps the Earth. It uses less energy and keeps the air clean. It also saves raw materials. For example, recycling aluminum uses only 5% of the power needed to make new metal.

How does it work? First, items go to a center. People might put them in bins at home. Then, workers sort and clean the items. Next, they reprocess them into new materials. Some things, like metal cans, can be made into the same thing again and again. Other things might become something different.

We can recycle many items. This includes glass, paper, and metal. We can also recycle plastic, tires, and batteries.

We can even recycle old electronics. These are called e-waste.

It is important to recycle e-waste the right way. This keeps harmful things like lead out of our world.

Recycling is the way we turn waste into new objects.

It is a very important part of protecting our planet. This process helps save raw materials from being used up. It also lowers greenhouse gas emissions to help the air. Using recycled things can reduce air and water pollution. This happens because we do not have to use as many landfills.

Recycling is the third step in the "Reduce, Reuse, and Recycle" plan. This helps keep our world sustainable for a long time.

How does this thing work?

First, people take items to a recycling center. Sometimes, workers pick them up from curbside bins. Next, the materials are sorted and cleaned carefully. After that, they are reprocessed into new materials for making products. Some things can become the exact same thing again. For example, old office paper can become new office paper.

Metal cans are special because they can be remade many times without losing quality.

People have been reusing materials for a very long time.

The writer Plato spoke about this in the fourth century BC. In the year 1031, Japanese shops sold paper that was repulped. In Britain, workers called "dustmen" collected ash from fires. They used this ash to help make bricks. In 1813, Benjamin Law found a way to turn rags into wool. This was called "shoddy" and was made in Yorkshire. This industry lasted until at least 1914.

Many different items can go through this process.

We can recycle glass, paper, cardboard, and metal. We also recycle plastic, tires, textiles, and batteries. Even food and garden waste can be recycled through composting. Some people even recycle old electronics, which is called e-waste.

In 1982, a system for aluminum cans was set up in Sweden. This helped recycling rates reach between 84% and 99%. In the 2000s, the amount of e-waste grew very quickly. In 2014, the European Union held about 50% of the world's recycling industry.

Recycling connects to many things you see every day.

You might see a blue bin at your house. You might even see a machine that gives money back for bottles. In the 1940s, people recycled as a patriotic duty during World War II.

Today, it helps save huge amounts of energy. For example, recycling aluminum uses only 5% of the energy needed to make it from scratch.

This helps keep our modern world running smoothly.

Recycling is the process of converting waste materials into new materials and objects.

This practice is a vital part of the "Reduce, Reuse, and Recycle" waste hierarchy. It aims to promote environmental sustainability and resource conservation. By redirecting waste output back into the economic system, recycling reduces the need for fresh raw materials. This helps lower greenhouse gas emissions and prevents the waste of useful resources. It also reduces air pollution from incineration and water pollution from landfilling.

The recycling mechanism follows a specific sequence to transform waste. First, materials are delivered to a household recycling center or collected via curbside bins.

Once collected, the materials undergo sorting and cleaning. After cleaning, they are reprocessed into new materials for manufacturing. In ideal implementations, this produces a fresh supply of the same material. For example, used office paper is converted back into new office paper.

Some materials, like metal cans, can be remanufactured repeatedly without losing their purity. Other materials are "downcycled," meaning they are reused to produce different, often lower-quality materials, such as paperboard.

Many different types of materials can be recycled. Common recyclables include glass, paper, cardboard, metal, plastic, tires, textiles, and batteries.

Even biodegradable waste, such as food and garden waste, can be recycled through composting. Another complex form involves the salvage of constituent materials from finished products. This happens when materials have high intrinsic value, such as gold from printed circuit boards.

It also occurs when materials are hazardous, such as removing mercury from thermometers to ensure safe disposal.

Humanity has practiced reusing materials for thousands of years. The philosopher Plato recorded advocacy for reuse as far back as the fourth century BC. Archaeological studies show that ancient waste dumps often had less household waste, suggesting high recycling rates. In 1031, Japanese shops were already selling repulped paper. In Britain, "dustmen" collected ash from coal fires to use as a base for making bricks. In 1813, Benjamin Law developed a process in Yorkshire to turn rags into "shoddy" wool.

This industry combined recycled fibers with virgin wool and lasted until at least 1914.

Recycling became a matter of national importance during World War II. Governments faced severe material shortages and financial constraints. This led to massive government campaigns, such as the National Salvage Campaign in Britain. In the United States, the "Salvage for Victory" campaign urged citizens to donate metal, paper, and rubber. People viewed recycling as a patriotic duty to support the war effort. This era proved that chemistry could transform valueless items into valuable resources.

Modern recycling provides massive energy savings and economic value. For instance, recycling aluminum uses only 5% of the energy required for virgin production.

In 1982, Sweden established a system for aluminum cans that led to recycling rates between 84% and 99%. By 2014, the European Union held about 50% of the global waste and recycling industry. This industry had a turnover of €24 billion. However, the rise of electronic waste, or e-waste, has created new challenges.

While e-waste contains valuable metals like copper and gold, improper recycling can release up to 1,000 different chemical substances, including neurotoxicants like lead.

The global recycling market faces significant shifts and regulations. In 2015, the United Nations set Sustainable Development Goal 12, which focuses on responsible consumption and production. Target 12.5 aims to substantially reduce waste generation by 2030. Recently, the industry faced a crisis when China announced its "National Sword" policy on December 31, 2017. This policy banned the import of materials deemed too "dirty" or "hazardous." This caused a massive disruption, forcing many countries to find new ways to process their own waste and rethink how they ship materials to other nations.
