Composting food waste at home is better for the environment and actually saves on Co2 emissions. A commonly-asked question is “won’t this garbage compost naturally in the landfill?” The problem is that most household waste is put into plastic bags on the way to the landfill and it does not break down or allow air flow. Without the proper air flow the waste breaks down differently, ending up creating methane gas which is harmful to Earth’s atmosphere. When the same waste is composted at home, in the proper conditions, the waste decomposes aerobically using oxygen and very little methane is produced. After 9–12 months, you are left with sweet-smelling, nutrient-rich soil your indoor or patio plants can use to be healthy and it will not have cost you anything more than a bit of time. It’s a win-win for you and the planet!
Use a mixture of different types of materials for best results. You will learn the right balance over time, but a general rule is to use 1 part “greens” to 2 parts “browns”.
“Greens” (nitrogen-rich ingredients) – these are considered the “hot” materials or “activators”. They break down quickly, but if left by themselves become a smelly mess.
