“…In addition, in light of increasing concerns regarding material security, shortages and environmental pollution, realistic frameworks have emerged for processing waste as a resource in many parts of the world [26][27][28]. More broadly, waste recycling and reuse can provide a viable opportunity to augment traditional resource supplies, at the same time reducing the need for waste disposal [29].…”

Conventional waste management practices focusing principally on waste collection, treatment and disposal or even minimisation often prove insufficient to address resource management challenges in a sustainable manner. Taking into account the relationship between water provision, energy security and resource efficiency, a systems approach that delivers a strong information basis and provides opportunities for resource use optimisation at various levels of application provides opportunities for synergies that could deliver real benefits when cross-sectoral solutions are applied. By-products from sewage treatment in combination with organic solid waste such as food waste can provide a valuable source of energy if managed properly and utilised effectively. This way, waste can be seen as a raw material than can be turned into a resource rather than simply be discarded. As such, AD (anaerobic digestion), the co-digestion of food waste with sewage sludge, could become a strategic and cross-sectoral solution, if carefully applied, with the potential to convey beneficial synergies for the water and the waste industries. However, barriers to the development of such systems are diverse and often interlinked. Institutional frameworks, decision making constraints, and regulatory boundaries might still appear to require an answer for three different problems, but this can be overcome if presented as just three different parts of the same answer. Such synergies could deliver economic benefits from the additional renewable energy generated and its associated incentives, and savings on costs for the infrastructure required for the exclusive digestion of food waste.

The technique of volumetric reintegration in severely deteriorated stone materials is of major importance for the restoration of architectural heritage. In using mortars for restoration it is important to control aspects such as the colour and textural similarity in relation to the adjacent stone, minor or equal strength and equal or greater porosity/permeability with respect to the original stone. This latter aspect is of particular complexity because the percentage distribution of pore-size ranges should not differ from that of the original stone material. The invention patent (with numbers of publication ES2187245 A1 and B1 16. 06. 2004), owned by the University of Granada, allows the production of excellent porous stones for decorative work in construction and mortar for restoration of stone materials with controlled porosity. Both materials consist of ornamental rock waste, so that a particular recycling purpose is given to this type of material which is difficult to reuse. In this paper we present the manufacturing process of these artificial stones and porous mortars with decorative and restorative purposes, from the controlled mixture of aggregates of ornamental rocks, organic and inorganic binders and generators of porosity. Once the curing and hardening has been done it is worth noting that one of the most important aspects of the product is the generation of a complex connected porous system as a result of the incorporation of crushed expanded polystyrene, which is activated after hardening through the application of organic solvents.
