15 years ago, Mr. Kweku Anno, owner of Biofilcom, designed and built the first concept of a toilet system that functions independent of sewerage systems and septic tanks now called the BIOFIL™ system. This digester-based system was developed around two major components: a filtering system, which separates the solid from the liquid waste and the use of micro-organisms for the breakdown of the solid waste. Roughly five thousand systems have been built and installed up to 2014. The majority have been built in concrete. The production of concrete digesters has been improved in the last years and the workshop has expanded. The up-scaling of the production in the present design in concrete is difficult and very costly because of the long lead time of the components due to labour intensive production as well as the curing and drying time needed for the concrete components.
