In this work, biodrying process was studied as a technology to reduce mass of horticultural wastes in order to improve handle and transport of organic wastes. During biodrying water is evaporated and some organic matter is degraded by microorganisms, thus organic waste is stabilized. Six static piles were prepared inside a greenhouse, where three contained whole wastes, three with shredded wastes and a test pile outside. Ventilation duct was put in two piles for aeration improving.

Air temperature and relative humidity were monitored inside and outside the greenhouse. Mass loss, humidity, organic mater and total nitrogen in the wastes were measured. No difference in mass loss was observed between piles with and without ventilation duct, and between the shredded and whole wastes, but the loss of mass and weight were lower in the pile outside the greenhouse. Piles inside the greenhouse showed decreases of 80% and 75% in weight and volume, respectively. The data obtained in this work suggest that stabilization and volume reduction as result of biodrying improve the handle and transport of horticultural wastes minimizing the pollutant impact
