“…While energy has become a central topic on the European and Italian political agenda, bioenergies have attracted the attention of researchers, operators and policy makers [1,2]. In particular, in Italy, energy production from biomass is significantly subsidized through incentive schemes designed to economically sustain investments.…”

Evaluation of Net Energy Obtainable from Combustion of Stabilised Olive Mill By-Products

This work is aimed at calculating the energy content of the residues from olive oil production. Olive pulp, olive husk and sludge (a mixture of olive pulp and husk) have been analyzed separately. Olive Mill Effluents (OME) are normally a problem for olive mill farms, yet they may be used as feedstock for biomass-fuelled power plants. Nonetheless, OMEs are characterized by a relatively high humidity content and are produced only during the olive season. Thus, OME need a stabilization process to be employed as a solid biofuel throughout the year. The analyses conducted attempt an evaluation of the energy consumption of a three-stage stabilization process: drying, milling and pelletising. The net electrical energy available from OME is then calculated as a difference between gross energy available and energy consumed for stabilization. The gross available electrical energy was calculated based on direct energy conversion of the stabilized feedstock on a small scale direct combustion and Organic Rankine Cycle (ORC) turbine. Results show that OME are suitable for energy production. Approximately 4500 kJ/kg of net electrical energy may be obtained out of olive sludge or olive pulp, while olive husk shows a potential gross energy of 3400 kJ/kg.

“…Examples of products manufactured by recycling wastes include wood chips manufactured from scrap wood (Li, Koseki & Momota, 2006), refuse-derived fuel (RDF) manufactured from household-generated waste (Fu, 2005;, refuse paper and plastic fuel (RPF) manufactured from waste paper and plastic and sludge fuel manufactured from sewage sludge . Existing studies have shown that fermentation may lead to heat generation and fire (Koseki, 2011).…”

Trends of wastes-recycle generated from the food industry have started to appear. There are some cases in which food wastes or products manufactured by recycling have generated heat at the low temperatures because of fermentation or oxidization, resulting in spontaneous ignition during transport or storage. In addition, the case in which depletion of oxygen in the storage area owing to fermentation and oxygen deprivation causing death of workers has been reported.In this study, Soy sauce squeezing residue produced during the brewing of soy sauce and Fish meal produced during the processing of Fish residue were considered. Hazard assessment tests focusing on heat analysis were conducted, aiming to acquire basic data for recurrence prevention.

Sustainable Production of Bio-Combustibles from Pyrolysis of Agro-Industrial Wastes

Evaluation of the sustainability of biomass pyrolysis requires a thorough assessment of the product yields and energy densities. With this purpose, a laboratory scale fixed bed reactor (FBR) was adapted from the standard Gray-King (GK) assay test on coal to conduct fixed bed pyrolysis experiments on agricultural and agro-industrial by-products. The present study provides results on the pyrolysis of two types of biomass: chipped olive tree trimmings (OT) and olive pomace (OP). Solid (char) and liquid (tar) product yields are reported. Mass yields are determined and compared with values obtained in similar works. Results indicate that char yield decreases from 49% (OT-db) and 50% (OP-db) at 325 °C to 26% (OT db) and 30% (OP-db) at 650 °C. Tar yield is almost constant (42%) at different reaction temperatures for OT, while it decreases slightly from 42% to 35% for OP. Energy density of the products at different peak temperatures is almost constant for OT (1.2), but slightly increases for OP (from a value of 1.3 to a value of 1.4).
