THE LOVE CANAL STORY
• Love Canal was a waterway built in the 1800s next to Niagara Falls, NY.
• Hooker Chemical Company purchased the site and used it for a chemical dump 1942-53.
• Site was sold to local gov’t for $1. A housing development and school were constructed on the site in the 70s.
• Chemicals began seeping into basements. • Housewife and resident Lois Gibbs brought problems to
national attention in 1977.• Some families moved right away, some cleanup done.

Chapter 12.2
DEALING WITH SOLID WASTE PROBLEMS
![Page 15: Chapters 12.2 and 12.3 HAZARDOUS WASTE AND REDUCING WASTE](https://reader036.vdocument.in/reader036/viewer/2022062516/56649e2d5503460f94b1c340/html5/thumbnails/15.jpg)
HOW CAN WE REDUCE OUR PRODUCTION OF SOLID WASTE?
• 3 options for dealing with solid waste problems (Aka – the 3 R’s):
• Producing less waste (Reduce)
• Changing the materials used in products (Reuse)
• Recycle
![Page 16: Chapters 12.2 and 12.3 HAZARDOUS WASTE AND REDUCING WASTE](https://reader036.vdocument.in/reader036/viewer/2022062516/56649e2d5503460f94b1c340/html5/thumbnails/16.jpg)
PRODUCING LESS WASTE - REDUCE
• Less waste – fewer/smaller landfills – less pollution
• How can we produce less waste?
• Manufacturers can produce less waste by redesigning products to use less material
![Page 17: Chapters 12.2 and 12.3 HAZARDOUS WASTE AND REDUCING WASTE](https://reader036.vdocument.in/reader036/viewer/2022062516/56649e2d5503460f94b1c340/html5/thumbnails/17.jpg)
REUSE
• Reusable bags for groceries
• Repurposing household items for other things
![Page 18: Chapters 12.2 and 12.3 HAZARDOUS WASTE AND REDUCING WASTE](https://reader036.vdocument.in/reader036/viewer/2022062516/56649e2d5503460f94b1c340/html5/thumbnails/18.jpg)
COMPOSTING – (REUSE)
• “recycling” yard material
• Yard waste is biodegradable and therefore can decompose naturally in a compost pile
• Bacteria break down the waste until it becomes compost – a dark crumbly material that is rich in nutrients
![Page 19: Chapters 12.2 and 12.3 HAZARDOUS WASTE AND REDUCING WASTE](https://reader036.vdocument.in/reader036/viewer/2022062516/56649e2d5503460f94b1c340/html5/thumbnails/19.jpg)
RECYCLING
• Saves energy, water and other resources
• After recycled materials are collected they are taken to a recycling center where they are sorted, cleaned, sorted again and made into new products.
