In addition to the processing or manufacturing zone, sub-projects for transport, utilities, power, environment, urban land and real estate development form an integral part of an integrated industrial area. These facilities are non-core activities for SIDCs, hence inefficiency is inherent in such projects. Infrastructure projects related to transport, utilities like power, energy, water supply (including for industrial purposes), waste water treatment, collection and treatment, site restoration, social infrastructure, housing development and tourism (especially business tourism) are some of the prime sectors that can be targeted for development / investments on PPP basis. The assessment criteria for investment in above sectors on PPP basis are briefly discussed in this note.
