The role of Andalusian agri-food waste co-composting in greenhouse gas emissions

F.J. Ruiz-Castilla, M.C. Gutiérrez, José Ángel Siles, A.F. Chica et autres

Alperujo (AL), a by-product of the olive oil industry typically stored in evaporation ponds, poses valorisation challenges in Mediterranean regions. Co-composting with organic wastes—pig slurry ( PS ), sewage sludge ( SS ), and organic fraction of municipal solid waste ( OFMSW …

Advanced extraction of caffeine and polyphenols from coffee pulp: Comparison of conventional and ultrasound-assisted methods

Johanna Andrea Serna‐Jiménez, Laura Sofía Torres‐Valenzuela, A. Sanín Villarreal, C. Roldan et autres

Two extraction methods of caffeine and total polyphenols from coffee pulp waste were evaluated using water as solvent: conventional solid-liquid extraction (CSLE) and ultrasound-assisted extraction (USAE). A central rotary experimental design was applied in each case, after evaluating the effect of the …

Exploiting waste derived from Musa spp. processing: Banana and plantain

Johanna Andrea Serna‐Jiménez, José Ángel Siles, A.F. Chica

Abstract Banana and plantain ( Musa spp.) are among the most popular crops especially in tropical and sub‐tropical zones. Musa spp. is a unique, perennial, single‐harvest plant that after fruit harvesting is decapitated and generates large amounts of waste and by‐products: leaves …

Kinetics of combined hydrothermal pretreatment and anaerobic digestion of lignocellulosic biomass (pepper plant and eggplant)

K. Hamraoui, José Ángel Siles, A.F. Chica, M.A. Martı́n et autres

A large quantity of lignocellulosic biomass is generated annually across the world which leads to environmental pollution and requires valorization. This study investigated the effect of hydrothermal pretreatment on the anaerobic digestion and co-digestion of the residual pepper plant and eggplant with …

Identification and simulation of atmospheric dispersion patterns of odour and VOCs generated by a waste treatment plant

M.C. Gutiérrez, M.A. Hernández-Ceballos, P. Márquez, A.F. Chica et autres

The impact of odorous gases emitted from waste treatment plants (WTP) has been a major concern of communities living near these facilities. This paper describes the methodology used to estimate the dispersion of odorous and volatile organic compound (VOC) emissions from a …

A Review on the Applications of Coffee Waste Derived from Primary Processing: Strategies for Revalorization

Johanna Andrea Serna‐Jiménez, José Ángel Siles, M.A. Martı́n, A.F. Chica

Coffee is an extremely popular beverage worldwide. To obtain it, the berry must be depulped, fermented, washed, dried, and roasted, producing residues: pulp and husk, mucilage, and parchment. Recently there has been an interest in generating high-value products. In this article, advances …

Evaluating the thermal regeneration process of massively generated granular activated carbons for their reuse in wastewater treatments plants

P. Márquez, Almudena Benítez, A.F. Chica, M.A. Martı́n et autres

Wastewater treatment plants (WWTPs) use granular activated carbons (GACs) as odor retainers because of their high surface area and porosity. The volatile compounds retained in these GAC beds saturate their pores and are periodically replaced by pristine GACs, which are frequently made …

Valorisation of banana peel waste as a precursor material for different renewable energy systems

Johanna Andrea Serna‐Jiménez, Fernando Luna‐Lama, Álvaro Caballero, M.A. Martı́n et autres

The following different valorisation processes of banana peel waste (BPW) were evaluated: combustion, production of activated carbon/batteries, and biomethanisation. This study showed that the combustion of BPW is an interesting option with a zero-carbon cycle. A mass balance demonstrated a low concentration …
