“…Its use should be able to bring an economically favorable impact for a sustainable development if the price of the biodiesel can be made at par with or lower than the current fossil diesel's price. The use of jatropha oil as an inedible feedstock, in particular, has considerable potential due to its low cost of jatropha seed (0.10 USD/kg), low cost of biodiesel conversion (339 USD/ha/yr) and stable supply [1,2]. In addition, the use of biodiesel from biomass has been reported to reduce the environmental degradation [1].…”

Improving the yield of Jatropha curcas's FAME through sol–gel derived meso-porous hydrotalcites

a b s t r a c tThe conversion of fatty acid methyl ester (FAME) from triglycerides using heterogeneous catalysis has gained increasing interest due to the prospect of increased yield at reduced operating costs and reaction conditions. In this paper, meso-porous hydrotalcite was used to catalyze jatropha oil into FAME with relatively higher yield at atmospheric pressure and relatively low reaction temperature. The molar ratio of methanol to oil required was relatively low and the conversion was completed within few hours of reaction time. The reaction was promoted when moderate calcination temperature was applied, the disordered structure of the catalyst was maintained, counterbalance anions was removed, and phase transitions within the oxide lattice was induced. Despite the observed deactivation during successive reaction cycles due to adsorption of residual triglycerides, the catalyst performance was restored effectively by air-re-calcination.

“…Jatropha is being promoted widely and large scale production is found mainly in South America, Africa, India, and Southeast Asia (Openshaw, 2000). In Indonesia, J. curcas plantation has been promoted by the national government and reached 256,545 hectare in 2012, producing 513,082 tons seed per year (Lestari et al, 2015;Wahl et al, 2012). Up to 50% of the plant oil is pressed from the oil--containing seeds of J. curcas, leaving a press--cake (JPC) as waste.…”

Purpose The objective of this study was to identify the availability, possible applications, and economic potential of proteins that are present in different parts of the rubber tree. Proteins from non-food sources can be used in e.g. animal feed or biochemicals production with no or little competition with food production, rendering them important biobased feedstock. Rubber tree is primarily grown for its latex that is used in rubber production. Indonesia has the largest rubber plantation area that is mostly owned and run by smallholder farmers. Using non-latex fractions from the rubber tree may generate additional income, and increase the economics of rubber plantations in general. Methods Several biomass streams from the rubber tree and subsequent latex processing were considered. Data were compiled from literature, a case study, and interviews with researchers, smallholder farmers, and managers at rubber processing plant and plantation. Results Latex waste streams, seeds, and leaves were considered to have the highest potential based on the amount of available proteins, and processes to isolate proteins from these streams were proposed. Isolation of specific functional properties from natural sources requires complex (and expensive) separation processes and therefore only economically feasible when specific use of the protein(s) for high value applications can be identified. Purification of many interesting proteins from latex fractions has already been described. Processing of seeds and leaves may also yield useful proteins for food, other purposes, and also still unknown high value applications. Conclusions A biorefinery concept can be applied to obtain multiple products from the seeds and leaves, and protein extraction can be performed with available knowledge and technology. Small scale processing can be more beneficial for the farmers, especially if the products are used locally for feed.
