Vermicomposting of Lavender Waste: A Biological Laboratory Investigation

In the present work, lavender waste, a residue of essential oil extract industry, was used to feed Eisenia andrei with mature horse manure at ratios 0:100, 25:75, 50:50, 75:25 and 100:0 on dry weight basis. Vermicomposting carried out for 70 days in laboratory conditions. Biological parameters such as population build-up, total biomass, mortality cocoon production were observed measured. Increasing concentrations waste affected positively growth reproduction worms significant way. The 100% combination showed best even tripled their biomass first week. A seed germination test also made, where no evidence toxicity found. index range was, general terms, above 100. results indicated that earthworm E. able transform into compost thus play major role industrial management apply circular economy.
