Trash/Recycling/Compost Information

As part of a group project, we compiled information about what you throw away at UCSD dining halls. We noticed that many students sort their trash wrong. There is a lot of plastic in the compost bin and food in the recycling bin, and students either don't understand why proper sorting is important or don't know what belongs in each bin. We're hoping that by providing some information about it that it will be less of an issue in the future.

Below we have some basic information about the basics of waste sorting and why it's important, links to our sources and further reading, and pages that we have made as resources for education.

Why Compost?

Composting reduces waste

Organic waste makes up 25-50% of what people throw away
When thrown away it decomposes in landfills and releases methane gas, a potent greenhouse gas

Compost is great for plants, lawns, and gardens

Increases organic matter in soil
Helps plants absorb nutrients already in the soil
Makes clay soils more airy and drain better
Helps sandy soils retain water
Helps balance pH of soil
Can extend growing season by moderating soil temp.
Can help control soil erosion
Provides excess nutrients for worms (vermicompost)

Compost conserves resources for

Water: Compost helps soak up water, then slowly release it to the plants, also allowing you to water less. It also can keep water from evaporating by acting as mulch
Energy and fuel: Not only does it keep this material out of landfills, but keeps it from being transported as well.

Composting saves money

In areas where you pay for your trash weight, the savings can be huge. Because much of compost contains a lot of water, compost weight is significant. Also, you don’t need to buy compost from the store.
