Abstract
Biomass is a renewable energy source that, due to its high seasonality, needs to be stored, handled and managed in suitable conditions for its optimum use. Sustainable storage is, therefore, a key process in which biomass can lose much of its qualities as fuel. The article presents an exhaustive bibliographic review of the factors that affect the quality of biomass during storage and the interactions that occur among them. Humidity, type of product, granulometry, size of the stockpile, airflow, temperature, and microbial action are analysed as the main factors affecting biomass during storage, and the results are compared with the tests that have been carried out on biomass from olive groves and olive oil industry. Recommendations are presented so that, using a correct storage method, losses, degradation and self-ignition risks are reduced and the energy quality of the fuel could be improved, taking advantage of the storage process to optimize the net energy yield.
Highlights
Since prehistoric times, humans have used wood and other organic waste as a source of energy
Zabetti et al [26] highlights how the ISO classification maintains as biomass quality parameters those strictly related to the energy content of the wood chips, such as moisture content, while it is more tolerant in terms of particle size classification
The action to be taken on biomass during the storage process, from start to finish, will depend mainly on the physicalchemical characteristics that the product is collected with
