Composting can be done at every scale, from a few kitchen scraps up to large amounts of agricultural "waste."
Composting saves biomass out of the trash stream and the landfill (up to 40% of household trash is compostable) and turns it into the perfect soil amendment, full of nutrients and with high moisture retention.
Composting can be done in many ways, from the traditional "pile" to commercial bins that may even be used indoors.
