How to Handle Solid Waste 1.Bury it- Pros -gets ride of the waste -clay cap so rain water doesn’t get into landfill Cons -dangerous -unsightly -rainfall causes bad chemicals to release and cause the leachate Leachate- polluted liquid caused by rainfall on a landfill -leachate runoff
2.Burn it- Pros -The buildings don’t take up much space -There is no risk to pollution to the ground -The heat the burning gives off is used as electricity Cons -There is pollution to the air -There is 90% remains -The process is expensive
3.Recycle it- Pros -Once you recycle the materials you can reuse the materials -There is no pollution -Most items are biodegradable Biodegradable- A substance that can be broken down and recycled by bacteria and other decomposers. Cons -Some items are not biodegradable
Metal Examples- Iron Aluminum Steel Desks Scissors Staples Paper Clips Metals such as iron and aluminum can be melted and reused. Recycling metal is less pollution and it saves money from making the metal brand new. Recycling metal helps conserve nonrenewable resources.
Glass Examples- Bottles Fiberglass Bricks Tiles Reflective paint on road signs Glass is made from sand, soda ash, and limestone. These materials are heated and mixed together. Glass is easier to recycle because, glass can always be melted down and reused. Recycled pieces of glass can melt at a lower temp. so that also saves money.
Plastic Examples- Bottles Milk Jugs Detergent Containers Soda Bottles When oil is refined for making gas and petroleum products, solid materials are left over called resins. These can be heated, stretched, and molded. These are plastic products. The 1 and 2s on the bottles tell you how items are recyclable.
Paper Examples- -Newspapers -Computer Paper -Paper Products Did you know it takes about 17 trees to make one metric ton of paper? Mills turn trees into a thick liquid called Pulp. The pulp is then spread out and dried-dried into paper. Pulp can also be made from used paper. The papers must be washed to remove inks and dyes. Then the paper’s mixed with more water and other chemicals to make pulp. Most paper products can only be recycled a few times. Recycled paper does not have the same texture, nor as strong, as wood pulp. The new, recycled paper is darker, weaker, and rougher.
