Resumen:
The environmental and social crisis arising out of the organizational model socio-economic
model that exploits the natural resources taken as infinite for the production of goods and
services and sweeping nature with pollution conceived the notion of sustainability, which
proposes a more harmonious with the environment. This study builds on this pillar and aims
at implementing the emergy methodology in an agricultural system experimental production
of sesame irrigated with treated wastewater. The sesame is a seed oil has a high nutritional
value that is consumed for millennia and has great economic applicability in Northeastern
Brazil. The use of treated wastewater provides numerous benefits to crop, because, besides
being rich in essential nutrients for the plant (it was shown that irrigated with wastewater
showed better results in relation to water supply) may be a solution to water scarcity, since
agriculture is an activity that consumes water. The emergy evaluation, purposed by Odum
(1971) considers all inputs and outputs of the system as energy flows in a diagram drawn and
calculate emergy indices where examination plan efforts to improve the system consistent
with environmental sustainability. The emergy indices found are the following: PISTON
RINGS: 430000; Renewability: 49; income. Emergetic: 1.86; Emergy Investment: 10.0;
emergetic exchange: 6.01. The emergy of natural resources and a total of 8999 sej nonrenewable,
1169 sej, the materials used in the experiment a total of 1023 sej, while that of
services is 9129 sej. The total resources emerged from the economy is 1015 sej. The total
emergy output (products) obtained was 2355 sej.
