Research aims to bring the waste. The cashew nut shell the odor removal products. To reduce the use of chemicals. And reduce waste agricultural waste and Community Research finds that The cashew nut shell. When buming the charcoal. The moisture content is 5. 26 % with charcoal to absorb odors as well. The carbon shell of cashew nuts are finely ground can absorb it very well the pH of the solution averaged 8.17 ability to absorb the smell of charcoal bark seeds cashew nuts in a container that is stale take 3-5 days to product. Absorbs odors welL Vase Grapes on the product used the time to absorb the smell more than 5 days and less ability to absorb odors. The shell is made from cashew nut products odor removal is a method that can reduce the use of chemicals to eliminate any odor and reduce global warming and the other one.

The research in the aim for useless material from cashew nut shell produce are heating energy briquettes to use recompense energy fine wood and charcoal from natural. By the flour paste is join together pass procedure heating briquettes with hand press implement. It is cashew nut shell can make to burn with earthen stove high temperature stove and steel stove from cashew nut shell are still shape and have bring into fine crush machine receive dust charcoal. It is mixed dust charcoal with flour in ratio 5:1 (by melt flour into hot water one liter until flour paste) mixed and bring into heating briquettes with hand press implement receive heating energy briquettes are no broken. When we bring expose to the sun until dried. After that to test efficiency of heating energy to see that cashew nut shell can to produce are heating energy briquettes. It use heating energy in home family in community replace to use from fire wood and charcoal from natural and heating energy briquettes from cashew nut shell can to use a make cooking well no broken fire well and height heater. It is suitable to produce heating energy for to use home family communities or commercial production and industries are use heating energy from fire wood and charcoal.
