Ch. 19 Waste Management

All of the following are methods of solid waste disposal EXCEPT:

• landfills
• open dumping 
• incineration
• recovery 

A process in which mixed garbage is burned at very high temperatures is:

• recovery
• incineration
• leachate
• source reduction 

Hazardous waste is:

• corrosive
• ignitable
• toxic
• all of these

Which item should you NOT put in your compost pile?

• food scraps
• autumn leaves
• wood chips
• plastic

The three main categories of waste include municipal solid waste, hazardous waste, and:

• industrial waste 
• radioactive waste 
• wastewater
• green waste

Which is NOT a benefit of reducing waste?

• Lowers the cost of disposal

• Conserves resources

• Produces energy

• Produces less pollution

Why are non-biodegradable plastics a problem in the environment?

• They don't decompose or break down naturally

• They have a long half-life

• They are highly reactive

• They are commonly put in sanitary landfills although they belong in hazardous waste landfills

To prevent groundwater contamination, sanitary landfills are:

• Located far from populated areas
• Lined with plastic and clay
• Covered with cement
• Located on slopes so that water runs downhill

What is the collection of materials that can be broken down and reprocessed to make new items?

• composting
• incineration
• leachate
• recycling 

Reducing the amount of solid waste that we generate or make is called:

• recycling 
• composting
• source reduction
• incineration
