The melliferous potential and prospect of valorization of waste biomass of Coriandrum sativum, Salvia hispanica and Lavandula angustifolia for renewable energy

Abstract

We investigated some biological peculiarities of Coriandrum sativum, Salvia hispanica and Lavandula angustifolia. It was established the studied plant species is characterized by an extended flowering period, providing food for bees from June to mid-August, with a honey potential of 60-330 kg/ha. The analysis of lignocellulose composition of collected waste biomass - dry stalks suggested that dry matter contained 357-504 g/kg cellulose, 197-248 g/kg hemicellulose, 72-135 g/kg acid detergent lignin and estimated theoretical ethanol yield from cell wall carbohydrates varied from 398 to 533 L/t. The physical and mechanical properties of dry stalks biomass from studied plant species was 3.36-4.48% ash, 73.17-79.39% volatile matter, 17.19-19.83 MJ/kg HHV, 15.86-18.46 MJ/kg LHV and can serve as feedstock for production solid densified fuel-pellets for renewable energy production.
