Italian trip could inspire better waste management in India

One of the components of the visit to Italy by a delegation of leather industry figures from India earlier this autumn could have interesting consequences for common effluent treatment plants in tanning installations in the Asian country.

UNIDO sponsored the visit, which took place from October 7-13.

The Indian visitors, who went to several tanneries and treatment plant facilities in different parts of Italy, as well as to the Tanning Tech exhibition in Bologna, also spent time with a technology provider called Soltigua. The Emilia-Romagna-based company manufactures and installs solar energy plants that use parabolic trough reflector (PTR) technology.

Solar rays are reflected using parabolic mirror reflectors and the concentrated rays provide heat energy to a transfer medium, which in many cases is diathermic oil.

The leather industry delegation has expressed interest in applying PTR technology to common effluent treatment plants in India, with the specific suggestion that the technology may provide operators with an effective way to evaporate reject material from reverse osmosis plants.
