Is the process of reclaiming raw materials and reusing them to create new products.

Many of the products people use today are not biodegradable.

Most recycling focouses on four major categories of products:metal,plastic,glass and paper.

Metal is very common.

Recycling metal saves money and causes less pollution than making new metal.

Plastic.

When oil is refined to make gasoline and other petroleum products,solid materials called resins and left over.

Glass:is made from sand,soda ash,and and limestone mixed together and heated.

Glass is one of the easiest products to recycle because glass pieces can be melted down over and over to make new glass containers.

Recycling glass is less expensive than making glass from raw materials.

Paper.

It takes about 17 trees to make one metric ton of paper.

Paper mills turn wood into a thick liquid called pulp.

Recycled paper is not as smooth or strong as paper made from wood pulp.

There are ways individuals can help control the solid waste problem.These are some times called the three R's.

Reduce:refers to creating less waste in the first place.

Reuse:refers to finding another use for an object rather than discarding it.

Recycle:refers to reclaiming raw materials to create new products.
