Home and community composting represents a more efficient and sustainable alternative than external treatment of the organic fraction, since it allows quality compost to be obtained in the same home or municipality where the waste is generated, in addition to allowing the involvement and awareness of citizens about the importance of transforming organic waste into compost to return nutrients to the soil.

Home and community composting of organic waste has increased by 50% since 2011, with individual self-composting being the option carried out mostly.
Currently, composting represents only 1.6% of the organic waste managed, including those that are selectively collected (organic waste thrown into the rejection fraction is not taken into account).
