The NP-40/20CX series of composters can break down almost all organic kitchen waste in a single day, dramatically reducing the disposal volume and, at the same time, practically eliminating odors generated during processing. This energy-efficient system employs a blend of microbes that work at ordinary room temperatures and do not require a heater to raise the temperature of the waste. The Composting Bio Mix carrier has a long service life, and need only be replaced about every six months.
