A series of epoxidized oils were prepared from rubber seed, soybean, jatropha, palm, and coconut oils. The epoxy content varied from 0.03 to 7.4 wt %, in accordance with the degree of unsaturation of the oils (lowest for coconut, highest for rubber seed oil). Bulk polymerization/curing of the epoxidized oils with triethylenetetramine (in the absence of a catalyst) was carried out in a batch setup (1 : 1 molar ratio of epoxide to primary amine groups, 100°C, 100 rpm, 30 min) followed by casting of the mixture in a steel mold (180°C, 200 bar, 21 h) and this resulted in cross‐linked resins. The effect of relevant pressing conditions such as time, temperature, pressure, and molar ratio of the epoxide and primary amine groups was investigated and modeled using multivariable nonlinear regression. Good agreement between experimental data and model were obtained. The rubber seed oil‐derived polymer has a Tg of 11.1°C, a tensile strength of 1.72 MPa, and strain at break of 182%. These values are slightly higher than for commercial epoxidized soybean oil (Tg of 6.9°C, tensile strength of 1.11 MPa, and strain at break of 145.7%). However, the comparison highlights the potential for these novel resins to be used at industrial/commercial level. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42591.

“…The global shortage of fossil fuels and environmental concerns has sustained the interest in biodiesel production [19][20][21][22][23][24][25][26][27][28][29][30]. Biodiesel is a mixture of esters of long chain fatty acids and short chain monohydric alcohols (MeOH or EtOH).…”

Background: Replacing chemical catalysts with biocatalysts is a widely recognized goal of white biotechnology. For biocatalytic processes requiring low water containing media, enzymes for example commercial preparations of lipases, show low catalytic efficiencies. Some high activity preparations for addressing this concern have been described. Protein coated microcrystals (PCMC) constitute one such preparation. The present work describes a Combi-PCMC for synthesis of biodiesel from the oil extracted from spent coffee grounds. Results: Different lipases were screened for biodiesel synthesis from crude coffee oil out of which Novozym 435 gave the best conversion of 60% in 4 h. Optimization of reaction conditions i.e. % water, temperature and purification of coffee oil further enhanced conversion upto 88% in 24 h. A mixture of Novozym 435 and a cheap commercially available 1,3-specific lipase RMIM (from Mucor miehei) was used in different ratios and 1:1 was found to be the best trade-off between conversion and cost. The commercial preparations then were replaced by a novel biocatalyst design called Combi-Protein coated microcrystals (Combi-PCMC) wherein CAL B and Palatase were co-immobilized with K 2 SO 4 as the core and this performed equivalent to the commercial preparations giving 83% conversion in 48 h.

Abstract-Estimation of production cost and sensitivity analysis for small scale production of rubber seed oil and biodiesel was studied. The production unit is projected to be built in the ex-Mega Rice Project area south of Palangkaraya, Indonesia which has a serious land degradation and deforestation problem. The valorization of rubber seed to produce bioproducts is seen as a contribution to revitalize the area. The production cost for rubber seed oil and rubber seed biodiesel in a small-scale (55 ton/y) was estimated to be €0.42/L and 1.00/L, respectively. This value is comparable with the price of diesel in remote areas in the ex-Mega Rice Project area close to Palangkaraya (up to €1.25/L). The effects of capital investment, production capacity, price of co-product credit, employees' salary and price of raw materials towards the production cost of rubber seed oil and biodiesel were investigated in the sensitivity analysis. The cost of capital investment has a relatively minor impact on the production cost of the rubber seed oil and biodiesel. The production capacity has a very strong influence in the production cost of rubber seed oil. The effect of other input variables is significant and all are showing about equal sensitivity.
