“…Cantabria has been traditionally an agricultural region although, at the present time, this sector only represents the 4% of the GDP [14]. Primary sector generates waste streams from different sources: livestock, agriculture, forestry and food industry, which suppose a high variety of type of waste [15]. These wastes are generated in a dispersed manner, and in some cases in large quantities.…”

When there is a need to move smoothly and effectively from an abundance of detailed fi eld data to summarized information, indicators and indices are used. Indicators are important tools that assist decision-makers in formulating and implementing plans for the management of waste at different geographic levels. In Cantabria, a northern Spanish region, all waste streams generated are covered through four specifi c Waste Plans recently adopted. The present study is focused on the Primary Sector, Health & Veterinary Services Waste Plan (PHWP), which is the framework to the decision-making processes related to the generation and management of forest, agricultural, livestock, food industry and health & veterinary wastes. In this work, 16 indicators have been proposed to track the evolution over time of the management of these waste streams in the region and the degree of achievement of the policy objectives. This article discusses the way to obtain, analyse and evaluate valuable information to build the indicators, fi nding that only eight indicators can be applied at short term. In addition, a summary of these indicators is included, showing in general, a good trend of the evolution of primary sector, health & veterinary waste management. Finally, different actions to improve the quality of data used for the indicators development are proposed in order to obtain more useful waste indicators to the stakeholders.

“…Agricultural residues used as soil amendments or fertilizers may represent an excellent recycling strategy [54]. They are important to improve soil physical (e.g., structure, infiltration rate, plant available water capacity), chemical (e.g., nutrient cycling, cation exchange capacity, soil reaction), and biological (e.g., SOC sequestration, microbial biomass C, activity, and species diversity of soil biota) properties as organic soil conditioners [55][56][57][58].…”

“…Incorporation of vegetable crop residues affects soil quality not only in terms of nutrient supply but also by influencing soil food web organisms and improving soil physicochemical properties, resulting in a better environment for crop growth and improved productivity [62][63][64][65][66][67][68][69]. The application of organic residues on carbon and nitrogen mineralization and biochemical properties in an agricultural soil led to a significant increase in soil microbial biomass size and activity [54].…”

This chapter provided an overview of the physical properties of soils and their importance on the mobility of water and nutrients and the development of a vegetation cover. It also gives some examples of why the use of agricultural residues can affect positively soil physical properties. The incorporation of agricultural wastes can be a sustainable practice to improve soil characteristics, favoring a model of zero waste in agricultural production and allowing better management of soils. We review and analyze the effect of the use as amendments of different agricultural residues, on physical properties of the soil (e.g., bulk density, porosity, and saturated hydraulic conductivity), especially related to the movement of water in the soil.

Biochar derived from plant biomass has great potential for the decontamination of aqueous media. It is the need of the hour to test biochar derived from economical, easily available, and novel materials. In this regard, the present study provides insight into the sorption of two heavy metals, i.e., cadmium (Cd) and nickel (Ni), using native Arachis hypogaea and its biochar prepared through pyrolysis. The effect of different factors, including interaction time, initial concentration of adsorbate, and temperature, as well as sorbent dosage, was studied on the sorption of Cd and Ni through a batch experiment. Characterization of the native biowaste and prepared biochar for its surface morphology and functional group identification was executed using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Results revealed the presence of different functional groups such as −OH on the surface of the adsorbent, which plays an important role in metal attachment. SEM reveals the irregular surface morphology of the adsorbent, which makes it easy for metal attachment. Thermogravimetric analysis shows the stability of A. hypogaea biochar up to 380 °C as compared with native adsorbent. The adsorption efficacy of A. hypogaea was found to be higher than that of native A. hypogaea for both metals. The best adsorption of Cd (94.5%) on biochar was observed at a concentration of 40 ppm, an adsorbent dosage of 2 g, a contact time of 100 min, and a temperature of 50 °C. While the optimum conditions for adsorption of Ni on biochar (97.2% adsorption) were reported at a contact time of 100 min, adsorbent dosage of 2.5 g, initial concentration of 60 ppm, and temperature of 50 °C. Results revealed that biochar offers better adsorption of metal ions as compared with raw samples at low concentrations. Isothermal studies show the adsorption mechanism as physical adsorption, and the negative value of Gibb's free energy confirms the spontaneous nature of the adsorption reaction. An increase in entropy value favors the adsorption process. Results revealed that the sorbent was a decent alternative to eliminate metal ions from the solution instead of costly adsorbents.
