In this paper, we report extraction of cashew nut shell liquid (CNSL) from cashew nut shell waste (CNSW) and further use of residues for generation of activated …
The shell of the nut is approximately 1/8 inch thick. Cashew nut shell liquid is the pericarp fluid of the cashew nut. Natural CNSL is a mixture of phenolic compounds with aliphatic side chains, and these are 70% anacardic acid, 5% cardanol, and 18% cardol [57] (Fig. 3.6). Several methods can extract CNSL: hot oil process, solvent extraction ...
Groundnut shell ash (GSA) is one of the potential waste materials to be used for cement replacement. This article includes an experimental investigation on the …
Shell compartments comprise around 21–29% of the ground nut by weight [24, 25]. So, ground nut shell waste of around 11 million metric tons from the groundnut industry is generated per annum [26]. Also, a reasonable amount of groundnut shell is used as biomass for energy purposes. However, more groundnut shells are being disposed of …

Often their production is linked to a local agricultural resource, such as camellia plantations, in China, which produce energy-rich waste camelia nut shells (Zhang et al. 2015). Two …
Based on the findings of the study, the following recommendations are formulated: (1) the application of dried pili nut shell as aggregate to concrete based on like the specimen is suitable only for non-load bearing members the weaknesses of the s slab-on-fill and partition walls; be tested also in different parameters and characteristics of ...
The findings of the study emphasize that, although the replacement of ground nut shell ash for cement did not improve strength, GSA incorporated earth blocks were durable. Moreover, the earth blocks incorporated with even 40% GSA exhibited sufficient compressive strength, which is sufficient to be used for one or two-story …
Transportation of heavy crude oil through pipelines poses a great challenge in oil and gas industry. Crude oil chokes the pipelines when the temperature drops below the pour-point temperature. In the present study, a bio-based additive, i.e., Cashew Nut Shell Liquid (CNSL) has been tested as a flow improver for heavy crude. CNSL was …
