From an energy-efficient oil expeller machine, a water turbine that generates electricity through sewage water to a solar mosquito destroyer, a biomass gassifier and low-cost windmill-the National Innovation Foundation (NIF) has scouted and documented many innovations that have made a difference to the environment.

Apart from selling their innovative products to companies, these innovators have extended the art of these innovations to their village community.

For instance, a herbal dye-maker from Gujarat has taught his entire village the art of making and selling herbal dyes used in wooden artefacts. The non-toxic, herbal dye from plants fetches a good price to the entire village that now depends upon the business.

Anil Gupta, executive vice chairperson, NIF and senior faculty at IIM-Ahmedabad, said: "There are many technologies which have a tremendous impact on the environment. For instance, Premjibhai from Ahmedabad spent 15 years planting trees in Gujarat. He used to go on a bike with a seed bag and throw them on the roadside. The impact of a simple initiative like that would be that even if one seed became a tree, he would have planted 4 crore trees in Gujarat by now. Today, he has a group of young people who are carrying forward the initiative."

Brothers Mohammad and Mushtaq Hussain have a venture out of their creation of windmills using bamboo. About 50 windmills have been implemented in Kutch for pumping salt, thus giving a huge relief to salt farmers.

Similarly, Mehsana-based Kalpesh Gajjar, Ahmedabad's Moxad Pinakin Thaker and Shaikh Nazim, Rajkot's Mansukhbhai Prajapati have also developed eco-friendly innovations that have changed the lives of those in their villages.

Shaikh Nazim has developed a solar cooker that uses ordinary mirrors to reflect sunrays to cook food. Nazim has helped other aspiring entrepreneurs replicate his green innovation. The difference between his and other solar cookers is that small square mirrors are placed at intersection points of an iron wire grid instead of a large single piece parabolic mirror. The cooker costs Rs 2,500 and saves the time of cooking.

Vipin Kumar, chief innovation officer, NIF, said: "Innovations are usually born out of necessities and to find an alternative solution. Most innovators create products to benefit society at large. There is a demand for these natural, eco-friendly products among companies, too."
