Green Initiatives


Our director Mr. Ashok Agarwala probably has a green heart rather than a green thumb!! His collection of over 1500 species of plants within Tathastu, including many forest and medicinal varieties, probably makes it the biggest private collection. Our chief Gardener will be delighted to engage all botany enthusiasts and show them our unique collection...but may take days.

Rain Water Harvesting

We have 2 lakes admeasuring 2 acres on our 15 acres property. One natural and one artificially deepened. A good amount of money (guesstimate 40 lakhs) has been spent to ensure that rain water from every inch of our property including land and terraces is diverted to the lakes. Canals, underground pipes, drains, slopes all have been thoughtfully planned.

Drip Irrigation

To ensure that no water is wasted in nurturing the heavy plantation, we have covered the entire property by the world recognized and efficient Israeli technique of drip-irrigation. Minimum input maximum output including manpower.

Sewage Treatment Plant

Taking advantage of being in the same city as NEERI, the National Environmental Engineering Research Institute, we are proud to say that we now have a successfully working STP at an approx. cost of Rs. 25 lakhs at Tathastu designed by NEERI.

Biocompost Plant

Disposing garden waste & solid kitchen waste was a huge concern so we settled for a bio-compost plant with a crusher installed before it. At a cost of approx. 15 lakhs we are not only able to effectively dispose waste but also generate brickets which are used for bonfires and can also be sold as fuel.

Solar Energy Generation

We certainly need to do more in this area. We have been able to use only solar water geysers and solar street lights. Hopefully we will work on power generation in the future.


If one addresses the issues that supposedly make cement construction non-eco-friendly and ensures that it becomes resource efficient, then shouldn’t cement construction become more eco-friendly than other construction material like wood, bamboo, mud, etc. which are argued to be eco-friendly?

When cutting of wood & digging of earth are non-eco-friendly, then how does their use for construction become eco-friendly? Add the issues of heavy maintenance, termites, difficulty in making it insect proof, AC proof etc. and the purpose of our innovation will become appreciable.

Cement retains heat and requires more artificial energy to cool the interiors. So simply minimize the exposure to sunlight. We have taken the following steps:-
Roof top has been covered with canvas cloth stretched about 1 feet above the slab from parapet to parapet ensuring that slab doesn’t get heated.
Heavy plantation has been done around structures so that big trees prevent side walls from heating.
On certain walls that still remained exposed, we fixed wire net from ground till roof, on which creepers have grown, covering the wall from sunlight and looking pretty too.

Disposal of Plastic

We are at an advanced stage of setting up a plastic bottle crushing / grinding machine which will enable us to dispose off all mineral water bottles effectively. Presently it is difficult to transport due to it’s sheer volume. Once crushed/grinded it will take very less space and also give us a decent sale return.
