The thermal insulation in the Aerobin stabilizes temperature all year round to create the perfect environment for "hot composting", a process which not only speeds up the time needed to break down organic matter but also kill any dangerous pathogens, weeds and seeds that could could potentially be a risk to your garden. With a patented design that embodies innovation and technology, the Aerobin can accomodate a variety of organic materials such as food scraps (including onion and citrus), tea leaves, lawn clippings, leaves, twigs and even newspaper.
