What is Compost?Aerobic process Microorganisms (bacteria, fungi) decompose organic matter and use as a food source, producing heat, carbon dioxide, water vapor, and humus.67% of waste in the U.S. is compostable!

In low temperature phases a number of macro-organisms, such as springtails, ants, nematodes, isopods and earthworms also contribute to the process

Compost explanation-Chemical breakdown-Benefits of composting (soil health, nutrients, prevents runoff, methane emissions, etc)-What students can do to get involved on campus with composting2Benefits of CompostingAlternative waste disposalmethane reduction!Absorbs VOCs, odors, and other soil contaminantsSoil retention: prevents runoff and erosionReduce the need for water, fertilizers, and pesticidesHumus--a rich nutrient-filled material--increases the nutrient content in soils and helps soils retain moisture

-diverts from landfills, methane, climate changeextends landfill life: sociopolitical costs

3What Can I Compost?What Goes in the Compost Bins All food (including meat, bread, cheese, fruit & vegetables, pasta, tea bags, etc.) Food-soiled paper (e.g., paper plates, napkins, waxed paper cups, pizza boxes) Plant-based cutlery/paper products (wooden chopsticks/toothpicks (without cellophane decorative topsavoid these), biodegradable forks / cups)

What Does Not Go in the Compost BinsPlastic wrap, plastic utensils, wrappers, plastics of any kind.GlassMetalPlastic-coated paper (waxed paper is okay!)

Corn and sugar-based plastics and meat should be usually left out of backyard composters. Both of these materials are suited for commercial composting, such as the one used by Carolina Dining Services and collected by Brooks Contractors.

Value of Volunteers

ContaminationNon-compostable materials such as plastic and Styrofoam do NOT break down, but still end up in visible chunks in the finished product.Must be sorted out so compost is still usable and healthy
