The environment is constantly exposed to a variety of chemical loads from natural and anthropogenic causes (xenobiotic substances). However, anthropogenic origin is the main source of xenobiotic substances, such as heavy metals in the environment. Moreover, the presence of these elements in water and soil has significant consequences because they are not easy to remove or deactivate. It is well known that irrigation and composted material can add heavy metals to the soil and deteriorate the quality of soil and plants, as well as the agricultural production with a high risk for food safety. Even more, when compost is been used, increases the metal content in the soils. This paper makes an overview regarding the presence of heavy metals and the methods to remove them and minimize the environmental risk based on the use of zeolites as a sustainable and successful example.

The soil has lost organic matter in the past centuries. Adding organic matter to soils is one of the management practices applied to recover the levels of soil carbon of the past and to improve soil properties. Is it a good practice to reduce global warming? In fact, one of the practices promoted to combat climate change is increasing soil organic matter. However, the addition of organic residues to the soil could facilitate the liberation of CO2 and wastes could also have no positive effects on soil properties (i.e., pollution). In this sense, what it is important is: (a) to know which is the expected effect of the organic matter added to the soil; (b) how this application alters the soil processes; (c) which are the management practices that should be applied; (d) how much is the real amount of carbon sequester by the soil and; (e) the balance at short and long period after the application of the organic matter. The adequate strategy should be to favour the increment of biologically stabilized soil organic matter considering medium and long time. However, it is necessary to adapt the strategies to the local environmental conditions.

The European Union (EU) is one of the major producers of municipal solid wastes and has a common policy based on circular economy to reuse the wastes. However, there are differences between countries and the methods for disposal and treatments. Municipal solid waste (MSW) can be composted and recycled as a source of plant nutrients and improves soil properties. This chapter analyzed the production in the EU and the effects on plant nutrients and environmental pollutants when MSW is added to the soil. The origin of the waste and the compost-like output (CLO) derived is important to determine the expectative of nutrient availability and other possible risks. MSW is so heterogeneous, but after a good pretreatment, an organic-rich matter mix can be composted giving a stabilized organic matter. The addition of the CLO to the soils can improve the nutrient status and favor the bioavailability of nutrients (macronutrients and micronutrients). In general, an increment of N and P was found in the soils. Moreover, important micronutrient availability (Fe, Mn, Cu, and Zn) has been described. However, the presence of pollutants and their mobility should be considered as an environmental risk.

This study conducts a comparative analysis between Chilean and Spanish reality in regard to the recycling of aggregates and their reuse in road works and urban roads. The current situation of both countries was reviewed through different sources of information such as technical and legal regulation, projects and executed works, to then validate them in Chile by way of interviews to various professionals in the field of urban and interurban road construction, as well as others belonging to government bodies. Spain has extensive experience on this issue, as it has a culture of recycling and reusing aggregates that has produced excellent results, a situation which was taken into account to compare it to Chile’s reality. The conclusion is that currently, in Chile, although the existence of recycled aggregate use is known, this is not the case on a technical level for professionals in the sector. It lacks a specific government body that is in charge of this issue and does not have appropriate infrastructure for its treatment. The materials with a promising future within the construction sector are the production of crushed granular bases and the creation of low-resistance concretes, which cannot be used, as laws that regulate them are still being drafted.

The great extent of degraded soils in southeast Spain makes it necessary to carry out restoration and rehabilitation strategies. In addition, the great amount of wastes produced need to be properly managed. Several types of wastes and amendments (organic and inorganic) can be applied for soil rehabilitation and land restoration. When large areas must be restored several aspects should be considered, such as availability of the waste, its characteristics, and transport. This research focuses on the characterization and the cost of 12 waste types and amendments (such as sewage sludge compost, brown peat, black peat, fertilized peat, earthworm humus, straw hay, palm tree leaves, pine bark, exfoliated vermiculite, expanded perlite, limestone outcrops, and volcanic crushed stones) obtained from four different sources. All of them were characterized following the UNE standards for soil amendments and the cost was obtained as a mean value of four different sources. The results indicate a great variability of properties between organic and inorganic materials, as was expected. Depending on the type of restoration, the characteristics, and the cost, the materials can be selected for an adequate purpose. Sewage sludge compost is a good alternative for application in large areas related to its characteristics (organic matter content and nutrient availability) and low cost. For inorganic amendments, natural limestone outcrops were the low-cost alternative. The use of both wastes (composted sewage sludge and limestone raw materials) for soil rehabilitation can facilitate the reduction of landfill disposal and add value for these wastes. Moreover, the results are very useful for scientists and engineers who deal with the development of rehabilitation and restoration strategies.

The use of composted sewage sludge (SW) and limestone outcrop residue (LR) as water filter systems has been tested. An experimental design based on the use of columns (0–30 cm) was used with both wastes under a heavy irrigation regime (2000 mL/week) for 12 weeks. Half of them were irrigated with nonsaline water (NS) and the others with saline water (S). Four treatments combining the quality of the irrigation water and wastes were obtained: SW-NS, SW-S, LR-NS, and LR-S. The chemical oxygen demand (COD), biochemical oxygen demand (BOD5), and suspended solids were measured. The results indicated that COD and BOD5 were higher in the treatments with SW than LR, whereas saline irrigation did not modify BOD5 compared with nonsaline irrigation, but COD increased in both wastes. The environmental concern due to organic matter displacement in waters should be taken into account when using these wastes, especially SW. Moreover, the use of S may increase the COD with the consequent risk for natural water. When designing a filter system considering inert and organic matter, SW and LR can be effective materials and should be taken into consideration.

This article analysed the presence of trace metals (essential elements and pollutants) and soil properties in rural abandoned soils of a Mediterranean region. The soil properties determined were texture, pH, equivalent calcium carbonate, soil organic matter, availability of micronutrients (Fe, Mn, Cu, and Zn), and acid microwave digestion extraction to measure the trace metals considered as main pollutants (Cu, Zn, Cd, Cr, Ni, and Pb). Descriptive statistics and correlations were used to determine the relations among these parameters. pH, soil organic carbon (SOC), and clay were the main properties that controlled the availability of essential metals. pH was the main factor related to these metals in these calcareous soils. However, SOC, which can be incremented by adding organic fertilizers for soil rehabilitation as a sustainable practice, played an important role. Mean values of the metal composition in soils (Cu, Zn, Cd, Cr, Ni, and Pb) obtained in this study were similar to values reported for other areas in the Mediterranean basin.

For the first time, it has been investigated if the vitrification of palm biomass wastes that result from conservation works in a protected forest area would be possible. In order to reduce these types of wastes and to exploit their capability for obtaining materials with useful applications, previous chemical analysis and thermal behaviour at high temperatures have been investigated by XRF (X-ray fluorescence) and HSM (hot stage microscopy). Location of these biomass residues in phase diagrams and possible formation of crystalline phases are previoulsy outlined from the XRF chemical analysis and the HSM.

This article analyzed the use of composted sewage sludge and limestone outcrop residue as a source of saline pollution to groundwater due to their use in soil rehabilitation and land restoration. This experiment analyzed the salinity and some important anions and cations related to those wastes under an experimental design based on the use of columns (0–30 cm) formed by both wastes and a heavy irrigation regime. Two different quality waters (saline and nonsaline) were used for irrigation. The pH, electrical conductivity, anions (Cl−, SO42−, PO43−, and HCO3−), cations (Na+, K+, Ca2+, and Mg2+), and heavy metals (Fe, Mn, Cu, Zn, Cd, Cr, Ni, and Pb) were analyzed. The environmental risk of salinization due to the species associated with the use of these materials was important, although chloride and sodium were the most important favoring the salinization of water. The effect was especially detected in the first weeks, while sewage sludge added important amounts of salts to leachates. After that, salinity coming from the irrigation determined the salinization of the groundwater. The combination of saline water for irrigation with the compost has to be seriously considered as a source of salts and heavy metal pollution for surface and ground waters. Phosphate and trace elements pollution are clearly associated to the use of the composted sewage sludge.

Contamination of soils by potentially toxic elements (e.g. Cd, Ni, Cr, Pb) from amendments of biosolids is subject to strict controls within the European Union. Today, the use of biosolids to improve the nutrient content in a soil is a common practice. The present research was conducted to determine electrical conductivity in biosolid pellets (dry wastes) using an innovative methodology. On the other hand, the present study was designed to examine the partition of selected heavy metals in biosolid pellets and also to relate the distribution patterns of these metals.

The use of composted sewage sludge and limestone outcrop residue in land rehabilitation, soil improvement, and technosol making can influence the mobility of nitrogen compounds in groundwater. This experiment analyzed this source of possible pollution under an experimental design based on the use of columns (0–30 cm) formed by both wastes and a heavy irrigation regime. Two waters of different quality (saline and non-saline) were used for irrigation. The presence of nitrate, nitrite, and ammonium in the leachates was checked. The environmental risk due to the presence of nitrogen species associated with the use of these materials was very low in general, although nitrate was the most important compound affected by the use of sewage sludge compost and saline water. The combination of saline water for irrigation with the compost has to be seriously considered as a source of pollution for surface and ground waters, and the use of both resources may be a key factor to be studied (low-quality water and sewage sludge compost).

On-line monitoring of wastewater parameters is a major scientific and technical challenge because of the great variability of wastewater characteristics and the extreme physical-chemical conditions that endure the sensors. Wastewater treatment plant managers require fast and reliable information about the input sewage and the operation of the different treatment stages. There is a great need for the development of sensors for the continuous monitoring of wastewater parameters. In this sense, several optical systems have been evaluated. This article presents an experimental laboratory-based approach to quantify commonly employed urban wastewater parameters, namely biochemical oxygen demand in five days (BOD5), chemical oxygen demand (COD), total suspended solids (TSS), and the ratio BOD5:COD, with a visible and short wave near infrared (V/SW-NIR) spectrometer (400–1000 nm). Partial least square regression (PLSR) models were developed in order to quantify the wastewater parameters with the recorded spectra. PLSR models were developed for the full spectral range and also for the visible and near infrared spectral ranges separately. Good PLSR models were obtained with the visible spectral range for BOD5 (RER = 9.64), COD (RER = 10.88), and with the full spectral range for the TSS (RER = 9.67). The results of this study show that V/SW-NIR spectroscopy is a suitable technique for on-line monitoring of wastewater parameters.

The substitution of clayey raw materials for other wastes, in this case sludge rich in calcium carbonate, in the production of traditional ceramics could give rise into cost savings due to the utilisation and recycling of wastes as a secondary raw material. At the same time, it can be helpful for solving environmental problems associated with such wastes. This research shows the results of the addition to a clay of a calcium carbonate residue in different proportions (15, 20, 25, 30 and 35%) in a ceramic body. The most suitable products were selected regarding the mineralogical composition of the resulting ceramic material and its technological behavior. In order to evaluate the ceramic properties of the obtained material, several properties of processing and product (linear contraction, water absorption capacity, bending strength) have been determined. With regard to the technological properties of the final ceramic bodies, there seems not to be any clear relation between the values of linear contraction and the percentage of residue. However, the increase in water absorption with the increase in the residue percentage is evident. The addition of residue gives rise to a decrease in the bending strength. The selection of the adequate percentage of sludge to be added to the ceramic body will be controlled by the usual standards applied to specific construction materials.
