Nowadays, drying methods for municipal solid waste quality improvement have been adopted in the developed and developing countries to valorize wastes for a renewable energy source, reduce dependency on fossil fuel and keep safer disposal at landfills. Among them, biodrying, biostabilization, thermal drying and solar drying are the most common. Drying of municipal solid waste could offer several environmental and economic benefits. Therefore, this review highlighted the drying methods for municipal solid waste quality improvement around the world and compared them based on the reduction of moisture, weight and volume of municipal solid wastes against drying temperature and time by using statistical analysis. It was observed that the drying temperature of different drying methods accounted for 115 ± 40°C for thermal drying, 59 ± 37°C for solar drying, 55 ± 15°C for biodrying and 58 ± 11°C for biostabilization. Among the drying methods, thermal drying provided the shortest drying time. The moisture reduction, weight reduction, volume reduction and heating value increase of municipal solid waste could vary with drying temperature and time. Finally, the benefits and drawbacks of different drying methods were specified, and recommendations were made for the future efficient drying.

“…timber) is based on Fick's law of diffusion for mass transfer and Fourier's law for heat transfer, and is linked to the energy flow model through the mass and energy exchanges between the circulating air and the timber stack. Since the description of these fundamental equations in the drying model has been given in many previous papers, including Bentayeb et al (2008), Cabardo et al (2006), and Haque and Langrish (2001), only the governing equations related to the drying model are presented here.…”

“…Indeed, studying solar wood dryers through a combination of mathematical modeling and experiments permits the improvement of the energy efficiency of solar dryers and to quantify the variability in solar energy inputs and wood properties. A modeling and simulation of a wood solar dryer in a Moroccan climate have been proposed by Bentayeb et al (2008). A fairly simple model that considers an average temperature of the dryer (air, wood and walls) gave reasonable results.…”

“…The drying time was found to be closely linked to glass partitions and wood thickness, however, the type of ventilation was found to have no effect on the drying time. In the study of Bentayeb et al (2008), no comparison between simulated results and experimental measurements was presented. Considering this first approach insufficient for modeling an actual dryer, a second approach that considers for each element of the dryer and practical drying temperature has been recently developed by Bekkioui et al (2009).…”

This work presents verification of a mathematical model for drying of a wood stack in a greenhouse type solar dryer. A simplified heat and mass transfer numerical model has been developed with input parameters based on the actual metrological data of a Moroccan climate. For its validation, a comparative study is performed in this work; the present model is solved to simulate the solar drying of pine wood using experimental data of previous wood drying experiments. The average relative discrepancies between the model predicted and experimental data are 1,2% for wood moisture content, 1% for drying air temperature and 5% for the air relative humidity. The close agreement between the predicted and experimental results shows the ability of the model to reproduce experimental drying data for wood.
