An exploratory study of fibre microplastics pollution in different process stages of salt production by solar evaporation in Spain
Cledera Castro, María del Mar; Hueso Kortekaas, Catalina; Sanchez Mata, Carlos; Morales Polo, Carlos; Calzada Funes, Javier; Delgado Mellado, Noemí; Caro Carretero, Raquel (2024-06-15)Microplastics are a pollutant of growing concern. Several studies have found microplastics in table salt worldwide in the last decade, although most have focused on already prepackaged salt. To the best of our knowledge, ... -
Anaerobic digestion in wastewater reactors of separated organic fractions from wholesale markets waste. Compositional and batch characterization. Energy and environmental feasibility
Morales Polo, Carlos; Cledera Castro, María del Mar; Hueso Kortekaas, Catalina; Revuelta Aramburu, Marta (2020-07-15)The food industry is one of the major industrial sectors in Europe and Spain, and therefore one of the major waste emitters, especially organic ones that can be classified into three different fractions (fruit and vegetables, ... -
Anaerobic digestion of organic fraction combinations from food waste, for an optimal dynamic release of biogas, using H2 as an indicator
Morales Polo, Carlos; Cledera Castro, María del Mar; Revuelta Aramburu, Marta; Hueso Kortekaas, Catalina (2023-01-20)The objective of this study is to assess the effects of mixing the three elemental organic waste fractions (fruit and vegetable, meat, and fish) during anaerobic digestion. Batch experiments were carried out with fraction ... -
Bioconversion process of barley crop residues into biogas: energetic-environmental potential in Spain
Morales Polo, Carlos; Cledera Castro, María del Mar; Revuelta Aramburu, Marta; Hueso Kortekaas, Catalina (2021-04-01)Barley fields reach 1.7 million hectares in Spain, of which 320,000 are used to produce malt, generating 450,000 tons of crop residue from barley intended for malt production. One way to treat this waste in an environmentally ... -
Enhancing energy recovery in form of biogas, from vegetable and fruit wholesale markets by-products and wastes, with pretreatments
Morales Polo, Carlos; Cledera Castro, María del Mar; Revuelta Aramburu, Marta; Hueso Kortekaas, Catalina (2021-07-01)Residues and by-products from vegetables and fruit wholesale markets are suitable for recovery in the form of energy through anaerobic digestion, allowing waste recovery and introducing them into the circular economy. This ... -
Environmental analysis of the use of plant fiber blocks in building construction
Revuelta Aramburu, Marta; Verdú Vázquez, Maria Amparo; Gil López, Tomás; Morales Polo, Carlos (2020-07-10)Construction is a sector which produces high greenhouse gas emissions, which cause global warming. As such, it is becoming increasingly important to use sustainable materials which reduce the environmental impacts. The ... -
Ground source heat pump driven by reciprocating engine firing biomethane from wastewater treatment plant sludge in a cogeneration for district heating and cooling. A case study in Spain
Serrat Albano, Lorenzo; Linares Hurtado, José Ignacio; Cledera Castro, María del Mar; Morales Polo, Carlos; Hueso Kortekaas, Catalina (2023-01-25)Wastewater treatment plants are a key facility in municipalities to reach the required water quality before returning to the environment. Their energy consumption constitutes the most critical cost in their operation, ... -
