Liquid smoke has a very large use, it is a result of condensation or condensation of pyrolysis vapor, directly or indirectly from wood materials such as cashew nut shells. Cashew nut shell is an abundant biomass of cashew nut processing industry but its utilization is not optimal. The purpose of this study was to make liquid smoke from cashew nut shell waste (technological aspect) and conduct economic analysis (economic aspect) to determine economic feasibility. Liquid smoke is made by pyrolysis at a temperature of 150-450oC in a simple batch type reactor. The results obtained were analyzed for its chemical components using Gas Chromatography-Mass Spectroscopy (GC-MC) spectrophotometer analysis. The largest liquid smoke production was obtained at a temperature of 450oC and a time of 2.5 hours with a yield of 19.46%. The main chemical components contained in liquid smoke are phenol (36.310%), acid (12.947%) and carbonyl (16.715%) respectively. With a liquid smoke production capacity of 200 tons per year, liquid smoke products can be sold at a price of IDR 3,620,137,785/years. Total Production cost 2,572,976,800/years. Annual net profit 733,012,689. Investigation of the economic feasibility of liquid smoke production, seen from the Rate of Rate on Investment, is 15.65%, Pay Out Time is 2.99 years and Break Event Point is 49.05%

AbstractIn 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 carbon for removal of heavy metals and methylene blue (MB). Solvent extraction yielded 24.6 ± 0.4%, 38.2 ± 0.4% and 40.1 ± 0.9% for petroleum ether, hexane and ethanol respectively. Phytochemical screening showed presence of alkaloids, carbohydrates, saponins, phenols, tannins, flavonoids, amino acids, terpenoids, proteins, steroids, glycosides and carboxylic acids. The CNSL had a pH of 3.2, viscosity (104.6 ± 1.8 mPa s), moisture (6.5%), ash (1.6 ± 0.1%), refractive index (1.52 ± 0.001), specific density (0.9561 ± 0.0002 g/cm3), acid value (118.7 ± 9.2 mg KOH/g), free fatty acid value (60.1 ± 4.7%), saponification number (138.1 ± 3.2 mg KOH/g) and iodine value (188.1 ± 2.3 mgI 2/100 g). The average percentage removal of Cu (II), Pb (II), Cd (II) and Zn (II) was 99.4 ± 0.5, 95.4 ± 1.5, 99.5 ± 0.1, 98.4 ± 0.1%, and removal efficiency of MB at 50, 150, 250 and 350 mg/L was 99.63, 97.66, 96.48 and 94.81%, respectively. Equilibrium data were best described by the Freundlich isotherm model. The maximum monolayer adsorption capacity was 12.1 mg/g. The adsorption kinetics conformed to pseudo-second-order model. ∆G° was negative and a ∆H° of + 22.76 kJ/mol indicated that adsorption was endothermic. The ΔS° (+ 0.086 kJ/mol/K) showed that there was spontaneous interaction of the solution and adsorbate. These results show that CNSW is a potential bioresource for CNSL production for use in the paints, varnishes, surface coatings, agrochemicals and ethnomedicine industries. Residual shells can be exploited as fuels or converted to activated carbon for use as low-cost filters in water purification.

Temperature Time

Liquefied wood is one of the phenolic resin. However, unlike commercial phenolic resins that are normally synthesized by the chemical reaction between phenol and formaldehyde, liquefied wood is usually produced by reacting phenol with wood-derived materials, and catalyst at 120-180◦C. Depending on whether the catalyst is a base or a acid, the formed resin is a thermoset or a thermoplastic. In this study, wood liquefaction was prepared from a cashew nut shell waste (CNSW), phenol, and sulfuric acid catalyst. The cashew nut shell waste is taken from Binh Phuoc province - Vietnam and crushed to a size of less than 500 mm. Phenol and sulfuric acid catalyst are chemical experiments. The powder of cashew nut shell waste, phenol, and sulfuric acid were mixed and reacted at 150oC for different soaking times. An optimal soaking temperature time was determined through a cashew nut shell waste residue content in wood liquefaction products. The wood liquefaction products also were determined by a number average molecular weight (Mn) and a weight average molecular weight (Mw) by Gel permeation chromatography method (GPC); the function groups by Fourier Transform Infrared method (FT-IR). The results showed that the formed resin is thermoplastic and the optimal soaking time to prepared liquefied wood is 180 minutes. This sample has a residual cashew nut shell waste ratio of 9.44%, a number average molecular weight of 7552, and a weight average molecular weight of 10640. The liquefied wood from cashew nut shell waste can be used as a binder in the manufacture of the medium density fiberboard (MDF) or as a material to promote the sintered process in the production of woodceramic materials. In addition, the liquefied wood can also be pyrolyzed to form carbon fiber. Carbon fiber can be applied as reinforcing materials for ceramic products.

The energy and mass flow of the steam cooking operation of three readily defined small-scale cashew processing industries was studied to estimate the availability of cashew nut shell. The proximate analysis of cashew shell waste was carried out using ASTMD 73–75 method. The calorific value of the cashew shell was carried out using bomb calorimeter (ASTME 711). The thermogravimetric analysis of the cashew shell was carried out using TG-FTIR with 10∘C/minute heating rate. The study revealed that, the small-scale cashew processing industries followed steam-cooking process with average energy consumption accounted to be 2969.7 MJ per 1000 kg of raw cashew seed. The cashew shell waste generated in small-scale cashew processing industries was found to be 67.5% of total weight of cashew seed, which can be utilized as fuel for thermal energy supply. The average higher calorific value of the cashew nut shell was found to be 4890 kcal/kg. The thermogravimetric analysis revealed that 85% weight of cashew nut shell has been degraded at 500∘C and in 13 minutes. The availability and fuel analysis of the cashew shell as a fuel revealed its suitability as a supplementary fuel for thermal application through pyrolysis in the industry.

<p class="A-ISIABSTRAK">A study was conducted to explore the bioactive substances of some local plants in order to find their effectiveness as antioxidant, antibacteria and antifungi to be used as feed additives. Twelve plants material were used in this study. The total phenol, tannin and saponin contents in the plant extract were assayed. The extracts were also assayed on their antioxidant activities and on their ability to depress in vitro gas production of microbes obtained from chicken’s guts, their ability to inhibit growth of bacteria (E. coli and Salmonella enteridis) and fungi (A. niger). The results showed that the highest total phenol and total tannin contents were found in clove leaf extract, while the highest saponin content was found in Sapindus rarak fruit pericarp. The highest antioxidant activity was found in the leaffruit extract. Gas produced by microorganims was reduced to the level similar to antibiotic addition were found with addition of hexane- extract of leaffruit, kapok seed or methanol- extract of mangosteen fruit rind pulp or clove leaves. The best inhibitory effect on E. coli growth (measured by clearing zone) was found in methanol extract of S. rarak fruit. However, the most effective growth inhibitor for both E. coli and Salmonella was the liquid smoke of cashew nut shell. The best growth inhibitor for fungal growth was found in extract of clove leaves. Therefore, clove leaves extract (anti fungi), liquid smoke of cashew nut shell (antibacteria) and leaffruit (antioxidant) may have potential to produce feed additives to substitute antibiotic growth promoters.</p>
