Description

PROCESS OF CONVERTING NATURAL DRY WASTE LEA VES INTO A RAW

MATERIAL FOR INCENSE

FIELD OF THE INVENTION

[0001] The present disclosure relates generally to the field of converting biowastes into useful products. More specifically, the disclosure is directed to a method for converting natural dry waste leaves into a raw material suitable for manufacturing incense products. The disclosure further provides a composition for incense comprising the raw material and a process of production of incense.

BACKGROUND OF THE INVENTION

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the present invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Incense sticks have been with mankind almost since inception. They are widely used all over the world, for their scent or for offering prayers. Incense mainly comprises of “CHARCOAL” (major component) as base material and other raw materials such as Jigat powder/joss powder/guar gum and saw dust in small portions. The most popular and cost effective incense sticks are charcoal-based. Since charcoal is extensively used in this industry, there is a huge demand for the same in the market. In order to cater to this demand, large number of trees are being cut globally. Astonishingly, around 5 to 7 tonnes of wood must be burnt to produce 1 tonne of charcoal, resulting in rapid deforestation, higher carbon emissions and greenhouse gas emissions into the environment. All of these result in an increase in global warming. Thus, the current process of preparing incense products largely contributes to air pollution and harms the eco system and the need to look for alternatives is imperative.

[0004] Apart from charcoal as a raw material, there are alternative sources for raw materials available in the market suitable for incense including flower waste, herbs, coconut shells, cow dung, etc. These incenses have either limitation on availability of source or the manufacturing of raw materials and incense from these sources is laborious, in both cases the final product becomes expensive.

[0005] A leaf mainly comprises organic compounds such as sugars and other organic compounds. When a leaf reaches its maturity it falls off and begins to decay where the sugars and other organic compounds breakdown. However, dried waste leaves yet retain some amount of their organic nature which leaves an unpleasant odor when the dry leaves are grinded and powdered. Thus, these dried leaves powder when used for forming incense leave an unpleasant scent that cannot be masked completely even after applying perfume.

[0006] Thus, there is a need in the art to look for sustainable, eco-friendly alternate sources and processes of preparing raw materials for incense from these sources.

[0058] In an embodiment of the present invention, before grinding, the leaves may be segregated to remove any soiled leaves and thereafter cleaned to remove any dust and grease.

[0059] In an embodiment of the present invention, grinding may be performed by any method known in the art, including but not limited to, mortar-pestle, and the like. In an embodiment, the powder may be screened or sieved to remove any coarse particles before processing further.

[0060] In an embodiment of the present invention, the binding agent and saw dust powder are added in minimum amounts.

[0061] In an embodiment of the present invention, the binding agent may be selected from any natural binding agent including but not limited to joss powder, jigat powder, guar gum, and the like.

[0062] In an embodiment, the binding agent may be present in a weight range of about 10% to about 20% w/w with respect to the processed leaves, preferably about 10% w/w with respect to the processed leaves.

[0063] In an embodiment of the present invention, the saw dust powder may be present in a weight range of about 10% to about 20% w/w with respect to the processed leaves, preferably about 10% w/w with respect to the processed leaves.

[0077] Example 1: Preparation of Incense Sticks

Step 1: Dried waste leaves were sourced from large plantation/farms/societies etc.

Step 2: Dry waste leaves were segregated by eliminating soiled/ unwanted leaves and the dust particles were removed. Step 3: The leaves were then grinded into very fine powder.

Step 4: The powder further screened or sieved to remove any coarse particles before processing further.

Step 5: 100 gm dry leaf powder is then heated in a dry pan between 30 to 50 deg C and then kept aside to cool down for 10 to 20 minutes. Later 50 ml of solution (5%-10% acetic acid diluted with 50 ml of water to form a solution) is added and mixed thoroughly and kept aside for 15 to 20 min.

Step 6: Dry leaves power will then be mixed with 10% - 20% of binding agent (either jigat powder or joss powder or Guar gum and 10% - 20% of saw dust powder. Step 6: 150 ml of water is added to the above mixture and kneaded thoroughly to form a dough.

Step 7: The dough is applied on the bamboo sticks, either hand rolled or machine made and kept aside for drying for around 24 to 48 hrs.

Step 8: The dried sticks are applied with white oil (diethyl phthalate, DEP) mixed perfumes and again dried for around 5 to 10 hrs.
