Biomethane Yield from Energy Plants in Latvia

Adamovič , V. Dubrovskis & I. Plume
Introduction of new energy plants for biogas production is necessary for Latvia in renewable energy development. Investigations were provided on sunflower, hemp and sorghum to evaluate its suitability for biomethane production in Latvia. Sunflower (Helianthus annuus L.) is used for decades for fodder production. Hemp (Cannabis sativa subsp. sativa) is variety allowed by legislation and was sown on 59 ha in Latvia in 2006.
