Jatropha voor duurzame biobrandstoffen, veevoer en lignocellulose

<ul> <li><em>Jatropha curcas</em> is a perennial tropical species which has been hailed for numerous claims that still have to be proven at larger scale in many tropical countries. <em>J. curcas</em>’ productivity in terms of oilseed production in relation to environmental conditions and crop management is still uncertain, amongst others because of unsystematic and unreliable data collection. Jatropha producers are looking for options to increase the crop’s profitability by looking for the use of <em>Jatropha curcas</em> by-products (pruning wood and press cake) for BbE. There is a need for knowledge development on jatropha (by-) products in sustainable tropical production systems, especially on the oil, press cake and lignocellulose productivity in response to management options.</li> </ul>

Jatropha producers are looking for options to increase the crop’s profitability by looking for the use of Jatropha curcas by-products (pruning wood and press cake) for BbE. There is a need for knowledge development on jatropha (by-) products in sustainable tropical production systems, especially on the oil, press cake and lignocellulose productivity in response to management options.


Projectdoelstelling

Knowledge development on the use of multiple jatropha products (oil, press-cake for feed and lignocellulose), the exploitation of non-phorbol ester (non-toxic) jatropha and the organization of sustainable agro-production systems that integrate multiple functions, including food and feed and bioenergy production.

Werkwijze

Agronomy trials (factorial design with fertilizer, and density) with low-phorbol ester and toxic jatropha accessions in different countries are analysed for the productivity of different jatropha products, ranging from fruits, seeds, oil and press-cake to lignocellulose materials from plant residues and pruning material. Experiments have been planted in 2010, have been redesigned in 2011 and will continue until 31-12-2015. As a perennial we need long term experiments. In 2013 the project will 1) analyse preliminary results on crop oilseed and by-product productivity of different jatropha accessions in Indonesia, 2) the project will contribute to the Jatropha curcas breeding programmes, by applying internationally developed descriptor lists of EU FP7 JATROPT, and 3) a business case for jatropha oil and by-products in Indonesia will be designed

Projectresultaat

Quantitative analyses of the productivity of jatropha products in different environments, production systems and with different management options, quantitative and qualitative data for plant breeding purposes, and a business case for local jatropha products.
