“…Therefore, the use of alternatives to improve the nutritional status, such as designs with mixed plantations that include nitrogen fixing species [155] or alternative fertilization through the use of sewage sludge or waste water, have gained prominence in recent years [184][185][186]. Besides not having to use traditional fertilizers, these materials are purified and/or reused and the plantations thus act as phytoremediators [187]. All these alternative fertilization techniques have also been tested in poplar SRC plantations in Spain in recent years, although all in experimental plantations [42,188,189].…”

“…The reusing of water from different sources represents a new approach in the context of SRC [187,188], with a solid background in the past [215,216]. In any case, it is necessary to increase the amount of research into the breeding of plants for production under conditions of water scarcity at a global level, especially in regions that suffer from water restrictions.…”

“…Other associated ecosystem benefits include an increased biodiversity (phytodiversity and zoological diversity) [32,331], erosion control and soil conservation [332], improvements in the water quality [333], and the role of the crop in phytoremediation [334][335][336]. In the case of Spain, the potential of the genus in the phytoremediation of soils has been evaluated through examples of the restoration of coal mining areas in northern Spain [131,337,338], or water phytodepuration [42,187,216,339]. Research has also focused on nutrient fluxes, evaluating the role of annual leaf litter in soil fertility throughout the rotation [340]; the quantification of accumulated carbon in both above-and below-ground fractions (reaching values of around 6.5 Mg C ha −1 year −1 in the above-ground woody biomass, around 1.0 Mg C ha −1 year −1 in the below-ground biomass [262], and around 2.5 Mg C ha −1 year −1 in the case of the litter [341]), as well as the economic implications of CO 2 capture [342].…”

“…Different options aimed at minimizing or achieving more efficient irrigation in Mediterranean environments have been mentioned in Section 3.3.4. The application of wastewater in poplar plantations not only constitutes an attractive method for producing biomass through the regeneration of wastewater, but also implies a reduction or suspension of fertilizer application [42,187,188]. Hence, this approach not only provides a sustainable way to minimize water use, but also takes advantage of the ability of these plantations as vegetation filters.…”

Developing a circular bioeconomy based on the sustainable use of biological resources, such as biomass, seems to be the best way of responding to the challenges associated with global change. Among the many sources, short rotation forest crops are an essential instrument for obtaining quality biomass with a predictable periodicity and yield, according to the areas of cultivation. This review aims to provide an overview of available knowledge on short rotation coppice Populus spp. plantations under Mediterranean conditions and specifically in Spain, in order to identify not only the status, but also the future prospects, for this type of biomass production. The analysis of available information was conducted by taking into consideration the following aspects: Genetic plant material; plantation design, including densities, rotation lengths and the number of rotations, and mixtures; management activities, including irrigation, fertilization, and weed control; yield prediction; biomass characterization; and finally, an evaluation of the sustainability of the plantation and ecosystem services provided. Despite advances, there is still much to be done if these plantations are to become a commercial reality in some Mediterranean areas. To achieve this aim, different aspects need to be reconsidered, such as irrigation, bearing in mind that water restrictions represent a real threat; the specific adaptation of genetic material to these conditions, in order to obtain a greater efficiency in resource use, as well as a greater resistance to pests and diseases or tolerance to abiotic stresses such as drought and salinity; rationalizing fertilization; quantifying and valuing the ecosystem services; the advance of more reliable predictive models based on ecophysiology; the specific characterization of biomass for its final use (bioenergy/bioproducts); technological improvements in management and harvesting; and finally, improving the critical aspects detected in environmental, energy, and economic analyses to achieve profitable and sustainable plantations under Mediterranean conditions.

“…In this system, wastewater treatment is a combined effect of soil, plants, and subsequent thrive of microorganisms. The treatment efficiency of this system has been reported (Aronsson andPerttu 2011, de Miguel et al 2014;Martinez-Hernandez et al 2018). In such systems, the main processes of contaminant attenuation include physical filtration, sorption onto the soil, biodegradation and plant uptake.…”

This study evaluated the combination effect of soil amendments with sandy soil on wastewater contaminants removal, and the ultimate impact on soil restoration. A soil column experiment was conducted with sandy soil (CK) or soil amended with 4% (w/w) compost, biochar or maize straw. Wastewater infiltration was recorded, and alfalfa was planted subsequently. Results showed that amendment of biochar and straw significantly decreased domestic wastewater infiltration rate in sandy soil, with a reduction of 62 and 50% compared to CK. All combination of soil and amendments had removal ability for wastewater contaminants, as indicated by the sorption capacity and the resist for desorption. The largest sorption capacity was found in biochar-amended soil. Plant and soil microbes also played important role in contaminants removal. The amendment of biochar and compost significantly improved plant growth, microbial abundance and diversity. The plant biomass of compost and biochar treatments was 3.8 and 4.6 folds of CK. After plant harvest, straw and compost treated soil had increased soil aggregates compared to CK. It is concluded that sandy soil-organic amendments-plant system could be used as an efficient wastewater treatment strategy for nutrient and pathogen removal. Moreover, wastewater input and plant cultivation could improve structure of the coarse-sandy soil.

This is a review of the literature published in 2018 on topics related to hazardous waste management in water, soils, sediments, and air. The review covers treatment technologies applying physical, chemical, and biological principles for contaminated water, soils, sediments, and air.Practitioner points The management of waters, wastewaters, and soils contaminated by various hazardous chemicals including inorganic (e.g., oxyanions, salts, and heavy metals), organic (e.g., halogenated, pharmaceuticals and personal care products, pesticides, and persistent organic chemicals) was reviewed according to the technology applied, namely, physical, chemical and biological methods. Physical methods for the management of hazardous wastes including adsorption, coagulation (conventional and electrochemical), sand filtration, electrosorption (or CDI), electrodialysis, electrokinetics, membrane (RO, NF, MF), photocatalysis, photoelectrochemical oxidation, sonochemical, non‐thermal plasma, supercritical fluid, electrochemical oxidation, and electrochemical reduction processes were reviewed. Chemical methods including ozone‐based, hydrogen peroxide‐based, persulfate‐based, Fenton and Fenton‐like, and potassium permanganate processes for the management of hazardous were reviewed. Biological methods such as aerobic, anaerobic, bioreactor, constructed wetlands, soil bioremediation and biofilter processes for the management of hazardous wastes, in mode of consortium and pure culture were reviewed.
