LEED Performance Buildings in the Northeast

Environmental benefits include composting toilets

Composting takes place in all soils that support plant and animal life. As waste breaks down in the composter a less chemically complex, more chemically stable substance rich in organic matter and very similar to soil is produced. Human waste consisting mostly of water is reduced by over 90%. By-products of the composting process are water vapor and CO2, and are released harmlessly into the atmosphere through the ventilation system.
