The composting is a process by which the natural conditions of decomposition of organic matter are stimulated, and the expenditures are considerably lower than those when the incineration of waste is carried out
The aromatic Plant biomass can be converted into useful compost or can be used for alternate purposes. Distillation techniques currently employed to produce essential oils from aromatic plants use large quantities of plant biomass often derived by cutting trees. With advances in solar power technology, it is theoretically possible to produce steam and use it for essential oil production. Solar-power home/office water heaters are already in use. It is time for someone to conceptualize and develop solar-power distillation units for essential oil production. Your ideas, views, suggestions and remarks are welcome. Compost is an organic fertiliser and soil enhancer formed by the controlled bio-oxidant decomposition of various mixtures consisting primarily of different plant residues, which are sometimes mixed with organic fertilizers and/or animal residues, and it contains limited quantities of mineral matter. Vermicompost (VC) produced from distillation waste of geranium (Pelargonium graveolens)
Composting is recommended in organic farming as a management tool for controlling weeds, pests and diseases. The incineration of organic materials is not allowed in organic farming, i.e. all organic waste from a farm has to be composted and returned back into soil in the form of compost. Mature compost must be hygienically correct and odour-free, with minimal amounts of pathogenic microorganisms or weed seeds
Well, the residues of aromatic plant distillation will be your substrate for composting. But, using only residues of this mentioned material will not give a good quality product. You need to add amendments that is, other organic substrates like animal manure, kelp, pumice, clay, biochar, sago waste, pomace, rock powders, coconut husk, sewage sludge etc... in order to balance the C/N ratio and moisture content.
