“…In fact, in this sort of plant an LHV above 8,500-10,000 kJ/kg is recommended, which is a value that was accomplished in the majority of cases (Table 2). These values are similar to other works as dried municipal solid wastes (8,200 -13,813 kJ/kg) (Zhang et al 2009;Sugni et al 2005), On the other hand, the levels of S, C and N were not high enough to cause problems due to atmospheric emissions. Furthermore, the volume of ash after incineration was not very high Therefore, aerobic fermentation, heat from the sun and chimney effect provides an increase in temperature that promotes the evaporation of the water content in the waste.…”

“…This method is different than other works of biodrying because they uses an external airflow to drag moisture (Sugni et al 2005;Navaee-Ardeh et al 2006;Zhang et al 2008;Zhang et al 2009;Velis et al 2009; NavaeeArdeh 2010).…”

“…In this experiment gardening and harvest wastes have similar initial moisture than other types of wastes as municipal solid wastes (66.7 -75%) (Adani et al 2002;Zhang et al 2008;Zhang et al 2009), or pulp and paper mixed sludges (75%) (Navaee-Ardeh 2006).…”

Abstract:Biodrying is a process that consists in reducing the moisture content and stabilizing organic compounds to obtain a useful product, such as a fuel, or as a previous step to landfilling. This is achieved by using the heat generated in the aerobic fermentation of organic compounds. The main parameters that control the process are aeration, the temperature reached in fermentation, and the initial level of moisture. In this work, the substrate was composed of agricultural harvest and gardening waste from an area in the east of Spain.The biodrying process was carried out in a greenhouse, where both the heat generated in the fermentation and the heat of the sun were used. In order to promote aeration, two factors were taken into account: one was the capacity of the shredded prunings to act as a bulking agent and the other one was a perforated floor, which allowed air to pass through. An air outlet was installed at the top of the greenhouse to promote the "chimney effect". With this setup, drying times of 12 to 30 days were achieved (depending on the month), together with volume reductions greater than 50%. The time of the trial has been assess when the waste has received 75 kW/m 2 . The final waste with a low level of moisture (7 -15%) had a heating value suitable for use as fuel (around 15,000 kJ/kg).

“…It has been used lately especially in the treatment of municipal organic solid wastes [12,13,14,15,16,17,18] . Its main advantage is the use of the thermal energy generated by the aerobic biodegradation of waste organic matter to evaporate water, thus, achieving self-drying [19] .…”

“…Biodrying biodegrades organic matter and reduces both the moisture content and pH of dissolved carbon and other substances [20] . This technique still needs further studies for final product and process improvement [12] . Among the drying methods presented, this review describes only the conventional drying methods which use hot air as a heat source.…”

The proper treatment of organic or inorganic solid wastes meets economic and especially environmental interests. Added-value by-products of market interest can be obtained through the recovery, reuse and treatment of solid wastes, which are otherwise discarded inappropriately in large quantities in the environment. In this review, the drying process is presented as an alternative environmental technology for the thermal treatment of residues of different natures from different origins. The main techniques applied to solid waste drying are described and in parallel the most relevant studies found in the literature which approaches this theme are analyzed. Moreover, the main dryers used nowadays are presented, as well as their most important characteristics. Some general aspects of the thermal and energetic performance of these dryers fundamental for process feasibility analysis are also discussed in this review. Essential aspects of the solid waste drying process are primarily presented with the purpose of showing the particularities that this theme offers when it comes to putting the theory into practice.
