This research aimed to develop and adapt technologies for aerobic biological treatment of household solid organic waste, in order to favor the implantation in homes and condominiums contemplating the principles of sustainability and social technology. The work was divided into five stages: Contact with families; Structuring and assembly of the experimental area; Development and adaptation of technologies for aerobic biological treatment of organic solid waste; Collection of solid organic residues in homes; Treatments of organic solid waste. This type of waste has high values ​​of organic matter and moisture, as well as pathogenic organisms. Two treatment technology models were adopted: cylindrical polyethylene composites (CPC) and rectangular aluminum composites (CAR). The treatment technologies showed different behavior in relation to the diversity of organisms and in relation to the physical and chemical parameters, verifying that the configuration of the composters has influence on them. When considering the stabilization time, ease of operation, small scale application and the quality of the final compound, the CPC model proved to be more efficient. Therefore, the technologies studied were feasible to achieve the objectives expected for the aerobic biological treatment of household organic solid waste: stabilization and hygiene of the organic portion with an average time span of less than 80 days.
