RESUMO:

The purpose of this work was to contribute to the promotion of ecological and scalable
solutions of domestic sanitation, specifically those related to resource recovery. The goal of
the thesis was to evaluate the energetic and environmental performance along the life cycle of
resource recovery from domestic sanitation in the Brazilian context, mainly in the semi-arid
region. Thus, a theoretical reference was presented on themes related to environmental
sustainability, industrial ecology tools such as cleaner production (CP), life cycle assessment
(LCA) and material flow analysis (MFA), the relation among domestic sanitation and
resources such as water, energy and nutrients, as well as different systems of domestic effluent
treatment. A theoretical reference on the state-of-the-art of the human urine use in agriculture
was presented. Human urine management was analyzed in technical, energy and economic
aspects in a case study of the Portal do Sertão region in the state of Bahia (Brasil). The
energetic and environmental performance along the life cycle of the human urine separation
and its application as fertilizer in agriculture was analyzed in different scenarios of transport,
ammonia volatilization and co-products in comparison to conventional practices. The Cone-
Invertido method was proposed to improve information continuously, support decisionmaking,
structure public policy based on techno-scientific advancement and compliance with
environmental targets. The results showed that the resource recovery from domestic sanitation
was potentially promising and more ecoefficient than the conventional solutions, mainly due
to the reduction of the water and energy demands; reduction of nutrient release into water
bodies or need to remove them from treated effluent; reduction of mineral fertilizer
production; as well as promotion of the circular economy by increasing resource security at
the regional level. Segregation of the domestic effluent flows proved to be advantageous
compared to conventional practices in the environmental categories evaluated, mainly in
regions with the generating source close to the fertilizer application site. It is recommended
that sanitary solutions be articulated with local resource availability to ensure water, energy
and food security, as well as social justice and economic feasibility. Therefore, the domestic
sanitation sector should be planned together with the housing, fertilizer, and agriculture
sectors.
