Paper recycling

There are three categories of paper that can be used as feed stocks for making recycled paper mill broke, pre-consumer waste, and post-consumer waste.

 Mill broke is paper trimmings and other paper scrap from the manufacture of paper, and is recycled internally in a paper mill.

 Pre-consumer waste is material which left the paper mill but was discarded before it was ready for consumer use.

 Post-consumer waste is material discarded after consumer use, such as old corrugated containers  old magazines, and newspapers.Paper suitable for recycling is called "scrap paper", often used to produce molded pulp package

paper recycling process:

The process of waste paper recycling involves mixing used paper with water and chemicals to break it down. It is then chopped up and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called pulp, or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de-inked, bleached, and mixed with water. Then it can be made into new recycled paper.

Recycling Basics:

Recycling:is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. Recycling can benefit your community and the environment.

Benefits of Recycling

• Reduces the amount of waste sent to landfills and incinerators;
• Conserves natural resources such as timber, water, and minerals;
• Prevents pollution by reducing the need to collect new raw materials;
• Saves energy;
• Reduces greenhouse gas emissions that contribute to global climate change;
• Helps sustain the environment for future generations;
• Helps create new well-paying jobs in the recycling and manufacturing industries

Steps to Recycling Materials

Recycling includes the three steps below, which create a continuous loop, represented by the familiar recycling symbol.

• Step 1: Collection and Processing
  There are several methods for collecting recyclables, including curbside collection, drop-off centers, and deposit or refund programs. 

  After collection, recyclables are sent to a recovery facility to be sorted, cleaned, and processed into materials that can be used in manufacturing. Recyclables are bought and sold just like raw materials would be, and prices go up and down depending on supply and demand in the United States and the world.
• Step 2: Manufacturing
• More and more of today's products are being manufactured with recycled content. Common household items that contain recycled materials include:
  • newspapers and paper towels;
  • aluminum, plastic, and glass soft drink containers;
  • steel cans; and
  • plastic laundry detergent bottles.
  Recycled materials are also used in new ways such as recovered glass in asphalt to pave roads or recovered plastic in carpeting and park benches.
