Waste Less Living

Quiz

1. The proper disposal of compostable products is? (specifically corn-PLA based products)

A. Backyard compost pile

Incorrect

The corn-PLA based cups and utensils add significant bulk to a backyard compost pile. They also require much higher heat for biodegradation to occur than what a backyard compost pile can typically provide.

B. Commercial composting facility

Correct

Compostable products are pre-processed (grinded and chipped down) prior to being mixed in with the other materials. Commercial composting also provides the higher temperatures needed for adequate composting of the product.

C. Trash
Incorrect.
In a landfill, compostable products do not break down into nutrient rich soil. They end up merely taking up valuable space for items and materials that need to be landfilled.
D. Recycling Bin
Incorrect.
Compostable products are plant based products NOT petroleum derived. Adding them to the recycling stream burdens the waste sorting process and contaminates the recycling stream.

2. Why does compostable tableware need to be commercially composted?

A. Commercial composting reaches and is maintained at a higher level of heat

Incorrect

Compostable tableware needs more than just high levels of heat to biodegrade into nutrient rich soil.

B. The products are chipped into smaller pieces

Incorrect

In addition to being chipped into smaller pieces, compostable tableware needs other variables to biodegrade into nutrient rich soil.

C. They can handle items in bulk

Incorrect

Being able to accept items in bulk is not the only reason compostable items biodegrade in a commercial compost facility.

D. All of the above

Correct

Commercial composting allows for pre-processing (ie., chipping and grinding) of bulky organic material, adequate and regular aeration, and higher heat and moisture conditions.

3. Which of the following cannot be put in a backyard composting bin?

A. Banana peel

Incorrect

A banana peel is an organic item that will not attract pests and will biodegrade in a backyard compost bin.

B. Dryer lint

Incorrect

Dryer lint, if primarily from non-synthetic fibers (i.e., cotton), is biodegradable that will not attract pests.

C. Latex glove

Incorrect

Latex is the sap that comes from the rubber tree and can be composted in one’s back yard.

D. Meat and cheese

Correct

Although meets and cheeses are organic items they have a high protein value and will attract pests and rodents. Also, due to their density and size meat and cheese is too bulky for the backyard compost bin.

E. Compostable utensils and corn based cups

Correct

Compostable tableware is meant for commercial composting. The product will likely just take up valuable space in a backyard compost bin.

4. Which of the following can be put in a commercial composting bin?

A. Plastic water bottle

Correct Incorrect

A plastic water bottle is a petroleum-based product. Petroleum is a non-renewable resource that will not biodegrade into nutrient rich soil. Plastic water bottles can be recycled, but not composted.

B. Soda Can

Incorrect

Soda cans are made from aluminum, which is not a renewable resource. Soda cans can be recycled, but not composted.

C. Leaves, meat bones, compostable cup and an apple core

Correct

Any item that is organic waste or made from a renewable resource can be composted in a commercial composting facility.

D. Glass Jar

Incorrect

Glass should be avoided in a composting bin at all cost. Glass is the number one contaminant to the compost waste stream and can significantly compromise the finished compost product. Glass jars can be recycled, but not composted.

5. True or False. Commercial composting is very expensive and energy intensive because of the energy required to heat the compost piles.

A. True

Incorrect

B. False

Correct

Compost piles are built to harness natural heat from the sun and bacteria.

6. Which of these is a backyard compost bin?

A.

Incorrect

This is a landfill.

B.

Correct

This is a homemade compost bin using wire mesh.

C.

Incorrect

This is a commercial compost facility.

7. Which of these is a commercial compost facility?

A.

Incorrect

This is a homemade compost bin using wire mesh.

B.

Correct

C.

Incorrect

8. How long does it take the average compostable cup to become compost in a commercial compost facility?

A. 6 months

Correct

B. 2 weeks

Incorrect

C. 7 days

Incorrect

D. 5 years

Incorrect

9. How long does it take an apple core to become compost in a backyard compost bin?

Incorrect

C. 7 days

Correct

D. 5 years

Incorrect

10. What is the difference in the soil produced by backyard composting and commercial composting?

A. Only Backyard compost increases the water retention of the soil

Incorrect

B. Only Commercial compost does not smell or attract pests.

Incorrect

If you put the correct items in your backyard compost bin and properly maintain it by turning it (aeration), it will not smell or attract pests.

C. Only backyard compost creates nutrient rich soil to be used in farms and gardens.

Incorrect

Compost from a backyard pile and a commercial facility is rich soil to be used in farms and gardens.

D. There is no difference in the soil produced.
