“…On the other hand, other models have used proximate analysis [7][8][9][10] or structural analysis [9][10][11]. Indirect calculation of the higher heating value by means of these types of models is justified by the expensive cost of the use of calorimeters [3,12]. The aim of this chapter is to compare the resources used in direct heat value determination with that used in indirect calculation from elemental analysis by means of prediction models in three common lignocellulosic materials coming from pruning Mediterranean fruit trees.…”

Pruning of fruit trees produces a great quantity of biomass each year that can be used for energy production. For this purpose, it is necessary to carry out an energy characterization of these pruned wastes, where the determination of heating value is significant. This value is usually measured by an adiabatic or isoperibolic calorimeter, which causes high economic costs and wastes time. The present study is focused on the development of indirect models for heating value prediction of biomass from orange trees Citrus × sinensis Osbeck, almond trees Prunus dulcis (Mill) D.A. Webb, and olive trees Olea europaea L. from an elemental analysis in order to reduce the time of determination as well as the economic costs. Residual biomass was classified and characterized according to CEN regulations such as received, without drying. Also, moisture content wet basis, bark ratio, density, heating value, and elemental composition (carbon, hydrogen, nitrogen, and sulfur) were measured. The influence of these variables on the heating value was analyzed. Finally, mathematical models were developed to predict this value for this studied species. These models showed coefficients of determination between 0.83 and 0.97, being suitable for industrial use.

“…In particular, it is possible to observe that the lower heating value of jatropha wood resulted in the range from 14 to 18 MJ·kg −1 , corresponding firstly to the value of herbaceous biomass, such as giant reeds, and the latter to lignocellulosic biomass, such as olive and vine prunings. It is well known that lignin is the component that has a greater effect on raising the HHV compared to other compounds in the wood [38][39][40]. In fact, lignin, cellulose, and hemicellulose have an HHV of 26.5 MJ·kg −1 , 17.5 MJ·kg −1 , and 16 MJ·kg −1 , respectively.…”

Jatropha (Jatropha curcas, L.) is an energy crop mainly cultivated for the oil-seed, and the oil is usually used as bio-fuel. However, few studies have reported information about the utilization of the wood as a fuel for boiler heating systems. With 2500 jatropha trees per hectare, it is possible to produce about 3 t·ha −1 ·y −1 of woody biomass from pruning. In addition, jatropha trees are commonly cut down to a height of 45 cm once every 10 years, with a production of 80 t·ha −1 of dry matter of woody biomass. The use of this biomass has not yet been investigated. During the European project JatroMed, woody biomass from jatropha pruning was collected in Morocco. Chemical and physical characteristics of the wood were conducted according to UNI EN ISO standards. The following jatropha wood characteristics have been analyzed: Moisture and ash contents, the ash melting point, heating value, and concentrations of C, H, N, and S. This research focused on the evaluation of the potential use of jatropha pruning for energy production, and the results represent critical data that is useful for future studies and business potential.

“…All the strategies mentioned previously, included in the framework of the bioeconomy strategy, combined with concerns about more expensive processes linked to efficient management of crop waste [61,95], and the latter's immense recycling potential [69], for many years (2008 to 2019, according to Scopus data) have created a need for research investigations and specific studies on the analysis of the properties of agricultural waste biomass from greenhouses in the province of Almeria, as well as the most viable alternatives for its exploitation and recovery. Results of these studies indicate that some crops, such as pepper, tomato and aubergine, have a higher lignin and cellulose content than others, for example, watermelon, melon and courgette [109,110]. Given the relationship between the contents of these components and their energy properties, the use of all plant waste could be limited to the production of energy.…”

For decades, non-renewable resources have been the basis of worldwide economic development. The extraction rate of natural resources has increased by 113% since 1990, which has led to overexploitation and generation of vast amounts of waste. For this reason, it is essential that a sustainable development model is adopted—one which makes it possible to produce more food and energy with fewer fossil fuels, low pollutant gas emissions and minimal solid waste. Certain management policies and approaches, such as the strategy of a circular ecocomy or bioeconomy, are oriented towards sustainable production and consumption. The present study focuses on the importance of intensive horticulture in the Mediterranean region, specifically in the province of Almería (Spain). After having conducted a study of the main crops in this area, it was determined that the waste biomass generated presented strong potential for exploitation. With the proper regulatory framework, which promotes and prioritises the circularity of agricultural waste, there are several opportunities for improving the current waste management model. In the same way, the results of the economic evaluation demonstrate that the alternative of self-management of waste biomass is profitable, specifically from tomato crops. Compost and green fertilizer production also prove to be a key strategy in the transition towards a more circular and sustainable agricultural production model. As for the said transition, government support is vital in terms of carrying out awareness campaigns and training activities and providing financing for Research and Development (R&D).
