Recycling- Converting waste into reusable materials.
1. Up-cycling vs down-cycling
- Up-cycling- reusing materials in such a way to create a higher quality or value than the original.
- Down-cycling- recycling that involves breaking an item down into its component elements or materials.
2. Types of plastics
- Dangers- DNA damage, abnormal muscle development, ect.
- This plastic consist of plastic bottles, polyester clothes, furniture, carpet
- Risk- With the production of HDPE comes with secondary health risk. This also limits the amount of HDPE we can recycle.
- HDPE is mostly made into milk gallons and motor oil, shampoos and conditioners, soap bottles, detergents, and bleaches.
- types of plastic- This plastic is used for all types of pipes, and tiles.
- Issues- not often recycled, VERY bad if ingested. This plastic should never come in contact with food.
- Plastic cling wrap, sandwich bags, squeezable bottles, and plastic grocery bags all are made from LDPE.
- Issues- This type of plastic is very durable and flexible. The bags don't tend to release harmful chemicals when come into contact with items. Which makes this plastic great for food handling. This plastic is usually not recycled but can be in certain areas.
- It is used to make plastic diapers, Tupperware, margarine containers, yogurt boxes, syrup bottles, prescription bottles, and some stadium cups.
- Issues- Using this type of plastic isn't good because its not as common to recycle PP, as it is (HDPE, LDPE)
- Disposable coffee cups, plastic food boxes, plastic cutlery, packing foam, and packing peanuts are made from PS.
- Issues- PS or Styrofoam can be recycled but it's not very efficient. It takes a lot of energy to recycle so most places choose not too.
- This catagory has so many different types of plastic it makes it hard to recycle. It can be harmful and dangers to recycle.
- Issues- Used in baby bottles, large water bottles (multiple-gallon capacity), compact discs, and medical storage containers. Recycled plastics in this category are used to make plastic lumber, among other products
Soil then vs now, soil then shows us that it helped us grow plants. then we (the people) stated using fertilizer. That showed huge results to our plants, but did they ever look into what it would do to our soil? The fertilizer we put in our soil has chemicals and the soil we have in the ground has the water we could be drinking! therefor its getting harder to purify the water.
