“…while generally producing some type of biomass waste. This biomass (from the above systems) can be used for energy but need to be studied from the logistical-environmental standpoint [5][6][7][8][9][10][11][12][13], analysed from the physical-chemical perspective [14][15][16], and submitted to different transformations (physical or chemical), to produce so-called biofuels [17][18][19][20][21][22].…”

“…One of the main characteristics of this organic biodegradable material generated in greenhouses is its high water content (60%) and its low weight to volume ratio [50,66]. However, this waste is typically mixed with non-biodegradable clips and raffia [95,96] used for tutoring plants, which makes its direct use non-viable and increases the costs of its exploitation as a by-product [94,97]. The estimation of the annual average production of waste biomass per crop was calculated by applying ratios of biomass generated by each crop type, previously determined by past studies [94, 97,98], to the average crop cover between 2014 and 2018.…”

The Management of Agricultural Waste Biomass in the Framework of Circular Economy and Bioeconomy: An Opportunity for Greenhouse Agriculture in Southeast Spain

et al. 2020

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).

“…[8] An additional environmental problem appears when these residues are deposited in an uncontrolled way. [4][5][6][7][9][10][11][12] An interesting procedure to diminish the impact of these residues and to profit them is the formation of compost. However, in that case, the generation of residues of high lignin content is an additional problem because lignin produces slower decomposition processes, with a lack of sustainable waste management practices.…”

“…Greenhouse crop residues from Almería (SE Spain) have been studied as an interesting source of renewable energy. [2][3][4][5][6][7][8] The energy potential has been reported, and models have been developed for the prediction of their higher heating value of biomass materials. [6,7] In any case, ashes are generated.…”

Characterization of ashes from greenhouse crops plant biomass residues using X‐ray fluorescence analysis and X‐ray diffraction

et al. 2017

A characterization of ashes obtained by thermal treatments on greenhouse crops plant biomass residues is presented. The chemical analysis, by X‐ray fluorescence (wavelength‐dispersive X‐ray fluorescence), and phase analysis, by X‐ray diffraction, of the resultant ashes are reported. Thermal treatments of selected samples of these residues increase the relative amounts of inorganic Mg, Si, P, and S in the ashes, being these amounts as high as increasing temperature. As an opposite effect, Na, Cl, and K contents decrease as increasing temperature by a volatilization process of the chlorides, as confirmed by X‐ray diffraction. The crystalline phase analysis of the ashes demonstrates the formation of inorganic constituents of the biomass, including alkaline chlorides and calcium salts (calcite, anhydrite, and apatite). Progressive thermal treatments induce the formation of new silicate phases (akermanite and grossularite) and silica (α‐quartz and cristobalite). Furthermore, the particle size of the starting biomass samples does not influence the evolution of the crystalline phases by thermal treatments. In contrast, a previous leaching using water and subsequent heating at 1,000 °C produces the formation of periclase (MgO), lime (CaO), and the silicate gehlenite, without the presence of anhydrite. This study is interesting for future investigations on the residues as a profitable biomass source for energy production and sustainable large‐scale management. Some potential applications of the resultant ashes can be proposed.
