Abstract
Kanji (sour rice gruel) is an acidic fermented preparation mentioned in many of the Ayurveda classics for various purpose like therapeutic use, pharmaceutical processes etc. A special method of kanji preparation is mentioned in Rasaratnasamuchchaya commentary by Acharya Dattatreya Anant Kulkarni and similar preparation is also mentioned in Rasayansara book recommended for the Parada samskara (mercurial processes) with some difference in ingredients. Kshara (alkaline preparation/ alkali) is an important preparation mentioned in classics. In Rasayansara text, Acharya Shyamsundar Vaishyaji has described a unique method of Kshara nirmana out of the leftover material of the Kanji. This kind of innovative methods should be adopted to recycle the leftover waste matters. It will help in regenerate the new pharmaceutical product. Here an attempt has been done by preparing the kanji and the kshara out of its residue material as mentioned in Rasayansara. First Kanji was prepared as per the reference of Rasayansara book and the leftover after filtration was dried. The kshara was prepared out of this dried leftover. Organoleptic and physicochemical analysis of the prepared kshara was done. The average yield of obtained kshara was 4.88%. The moisture content of the final product found very less while total ash value found on higher side. The pH value suggests its alkaline nature. It shows good solubility in various solvents and good water-soluble extractive value. Exploration of such innovative procedures where waste stuff is been recycled should be increased in present time.

Summary
Ayurveda (science of life) is witnessing a global acceptance and demand of the Ayurveda medicines and therapies are drastically increased in recent time. With the increased production of the medicines, resulting the growth in the pharmaceutical waste matter They are generating large volume of solid waste, oil waste, plant extract waste, residue of many filtrates used in various processes like kwatha (decoction), swarasa (juice) etc. All the leftover material can be recycled and another useful secondary drug or product can be prepared out of these waste materials. In this classical book many procedures has been introduced suggesting the reuse of the residue of pharmacy like preparation of Sangraha Sindura rasa [2], Bhasmani kosha etc. In the procedure of kanji nirmana, the leftover is usually thrown away as waste product It can be recycled and another useful product can be prepared by processing the leftover of Kanji. There is little variation in the ingredients like mulika (radish) not used in the Rasayansara method
