Combustible bio-oil was obtained by pyrolysis of *Cymbopogon flexuosus* distillation wastes in a fixed-bed reactor. Due to the low lignin content of the biomass, the bio-oil had a lower content of phenolic compounds than those obtained from other biomasses. It also had low concentrations of polyaromatic hydrocarbons and nitrogenous compounds. Combustion heat in the order of 30 MJ/kg was measured for this bio-oil [36].

The use of lavender (*L. angustifolia* Miller) distillation residues in mushroom production was examined by cultivating *Pleorotus ostreatus* on substrates composed of shredded lavender waste and barley straw, maintained at 24°C and 65–70% humidity for 50–60 days. Once the mushrooms were removed, the exhausted substrate was used as a soil conditioner or to produce biocompost. The entire mushroom production process was established to be cost-effective [37].
