Loowatt is a waterless toilet that aims to reduce water consumption in urban environments while producing energy through anaerobic digestion of human waste.
Loowatt is a waterless system that offers a sustainable method for waste disposal while producing energy and useful byproducts, such as fertilizer.
The core technology behind the system is the use of an odorless cartridge within a biodegradable polymer lining that stores human waste securely. The lining is directly introduced into an anaerobic digester to generate natural gas from human waste. The digester uses mesophilic bacteria to convert human waste through a series of intermediaries to methane, carbon dioxide and a solid byproduct, which can be used as a fertilizer.
While anaerobic digestion has been in use for a long time to generate natural gas and fertilizer, Loowatt is unique in that it has a sealing mechanism to package feces and urine into an odorless cartridge, within a biodegradable lining material. This eliminates the need for storage, handling and transport of the waste.
Reduction in water consumption, waste disposal, waste management and energy production are all achieved through the Loowatt’s well-designed, low-cost system.
