Abstract
Combustion tests and gaseous emissions of olive mill solid wastes pellets (olive pomace (OP), and olive pits (OPi)) were carried out in an updraft counter-current fixed bed reactor. Along the combustion chamber axis and under a constant primary air flow rate, the bed temperatures and the mass loss rate were measured as functions of time. Moreover, the gas mixture components such as O2, organic carbon (Corg), CO, CO2, H2O, H2, SO2, and NOx (NO + NO2) were analyzed and measured. The reaction front positions were determined as well as the ignition rate and the reaction front velocity. We have found that the exhaust gases are emitted in acceptable concentrations compared to the combustion of standard wood pellets reported in the literature (EN 303-5). It is shown that the bed temperature increased from the ambient value to a maximum value ranging from 750 to 1000 °C as previously reported in the literature. The results demonstrate the promise of using olive mill solid waste pellets as an alternative biofuel for heat and/or electricity production.

Summary
Agro-industrial by-products are viable alternatives to fossil fuels to reduce greenhouse gases emissions such as CO2 and NOx [1,2,3] Among these by-products, olive mill solid wastes (OMSWs) are generated in large quantities in the leading producers in the olive oil industry, including Spain, Italy, Greece, and Tunisia. Olive pits (OPi ) are a major bio-fuel in Spain [6], which is used in combustion processes to produce heat [7] owing to its low moisture content, high heating value, uniform size, and relatively high bulk density [8] Using this material as a biofuel can be considered as an economically viable alternative to fossil fuels [9]. Both OP and OPi can be processed into cylindrical pellets
