Breve descripción de la práctica óptima
Euphorbia tirucalli can be planted as feed-stock for bio-gas. The plant can be easily propagated by cuttings and establishes quickly. Within 1 year up to 2 years depending on plant density a fully ground covered plantation can be reached. The plant can be coppiced up to 20 centimeter from ground level and will grow back in 1 year. Depending on the availability of water and nutrients, temperature and radiation biomass production can vary from 3 to 50 MT of Dry Matter per hectare per year. The plant can be harvested and used at anytime in the year. Cut off branches are ground in a hammer-mill or other device and can then be used as primary or secondary feed-stock for bio-gas production. The residues of bio-gas production (slurry) is fed back to the plantation to ensure nutrient recycling. The bio-gas can be used for cooking or production of electricity, thus creating local energy security and independence from fossil fuels from abroad.|

¿En base de qué criterios o indicadores (no relacionados con la Estrategia) se ha considerado la práctica propuesta y la tecnología correspondiente como ‘óptima’?
The plant tolerates saline soils. The plant tolerates extreme dry spells. The plant biomass can be harvested all year round and used as feed-stock. It has a potential to produce large amounts of biomass per hectare per year. Once a plantation is established it will produce for a least 20 years before having to replant.
