Nature does its own composting. In warm weather, natural soil microorganisms digest and transform leaves, grass and other organic debris into a hygienic, inoffensive soil component. This compost provides the nutrients for new plant growth and holds moisture in the soil. Gardeners around the world utilize this process when they compost kitchen and garden waste and use the compost as fertilizer. BioLet unites the natural composting process with advanced Swedish technology to accelerate and optimize biological decomposition, evaporate excess liquid and exhaust odors… all within an elegant bathroom fixture that is easy to use, simple to install and economical to operate.
