The socio-economic activities due to world development are
promoting increasing pressures on land, creating competition and
conflicts, resulting in suboptimal use of resources. Integrated
planning and management of land resources is a top subject of
Agenda 21 (managed by FAO), which deals with the cross-sectoral
aspects of decision-making for the sustainable use and development
of natural resources. This is essential for life-support systems
and its productive capacity. In this context, there is a need to
find new strategies for sustainable development that links social
and economic progress with environmental protection and
enhancement. Electrokinetic transport processes (EK) uses a
low-level direct current as the "cleaning agent". EK has been
applied to the remediation of polluted soils and other contaminated
matrices. It also shows a great potential to be used in different
fields, as in saline soil restoration, nutrients recovery from
wastes or repair and maintenance of building structures. EK may be
an integrated approach for new strategies aiming at sustainable
development and to support waste strategies, with worldwide
interest. EK can also be coupled with phytoremediation and
integrated with nanotechnology, enlarging the scope of its
application. The conciliation of the EK in the recovery of
secondary resources, remediation and conservation is a
multidisciplinary novel approach that opens new technical
possibilities for waste minimization, through upgrading of
particulate waste products and the recovery of secondary resources
for industrial, agricultural or social use.
