For proper composting you will need enough leaves or other carbon sources for a 60:40 ratio of carbon to nitrogen. In other words, about 2/3 of your compost pile will need to be comprised of leaves or carbon sources.
Instruct students in proper lifting/hauling techniques for transporting the full compost collection containers to the compost area.

Start Up<br />Step 2<br />Decide if the school will compost material onsite or ship food waste to a commercial compost facility<br />To find a commercial compost facility:<br /><ul><li>Ask your current trash hauler
Look online or in the phone book under composting
Other Materials You Will Need<br />Begin gathering leaves, straw, & other carbon (“brown”) sources<br /><ul><li>Distribute a message to teachers, parents, & community asking for sources to be brought to the school
The Process<br />Decomposers: bacteria, fungi, actinomycetes<br />Heat is released by microorganisms during aerobic metabolism of an organic substrate (e.g. glucose)<br />Temperature influences microbial population<br /><ul><li>Initial stage: Mesophilic bacteria
Compost System Maintenance<br />Regularly review tasks with participants<br /><ul><li>Acceptable materials, collection logistics, maintenance, etc. </li></ul>Review proper attire, proper hygiene (e.g., gloves, washing hands), proper lifting<br />Review how to safely handle shovels/other tools<br /><ul><li>Proper way to hold & use shovels to load & mix materials
So…<br />50 pounds of food waste per week = ~15 gallons<br />Add at least 2x the amount of brown "bulky” to calculate total gallons-per-week figure<br /><ul><li>15 gallons of food waste + 30 gallons of brown materials = 45 gallons
Off-Site Options, cont.<br />Determine exact materials that are acceptable by farmer or compost operation<br /><ul><li>A compost operation or digester can often accept soiled paper (such as napkins) & all food scraps, even meat
Off-Site Options, cont.<br />Develop a collection plan (same as for onsite composting)<br />Determine how the materials will be stored before going to the farm or compost operation <br />Determine how materials will get from the school to the farm or compost operation <br /><ul><li>Is there a local hauler that collects organics?
Would the farmer be willing to collect the materials?
