While many schools already recycle, not as many commit to composting their organic waste. Composting reduces the amount of trash going to landfills, ensures nutrients are returned back to the soil, and can help in setting up a school garden. Non-organic fertilizers, commonly used to keep lawns looking green and healthy, contain petroleum. Composting is a free and easy way to keep your school’s lawn looking and feeing good while reducing oil consumption. You can subtract 300kg of carbon dioxide (CO2) per year from your school or household Greenhouse Gas emissions by putting out one less bag of otherwise-compostable garbage per week.
