Wine Production Wastes, Valorization, and Perspectives

, 2023
The wine sector generates high quantities of residues that are still poorly exploited as feedstock. Normally, these wastes are directly discarded into the fields or burned, thus causing environmental problems. Wine production wastes, like vine pruning and grape pomace, are available at relatively low prices and are considered prime materials for ...

Food and Market Waste–A Pathway to Sustainable Fuels and Waste Valorization [PDF]

Energy & Fuels, 2019
Food and market waste (FMW) is one of the most abundant unrecycled products which poses waste management issues and negative environmental impacts. Thermo-catalytic reforming (TCR) is a pyrolysis based technology which can convert a wide range of biomass wastes into energy vectors bio-oil, syngas, and char.

Laccase pretreatment for agrofood wastes valorization

Bioresource Technology, 2018
Apple pomace, potato peels, and coffee silverskin are attractive agrofood wastes for the production of biofuels and chemicals, due to their abundance and carbohydrate content. As lignocellulosic biomasses, their conversion is challenged by the presence of lignin that prevents hydrolysis of polysaccharides, hence demanding a pretreatment step.

Separation and Valorization of Chlorine From Tail Gas Streams

Angewandte Chemie International Edition, EarlyView.
A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

Zero-waste valorization of agricultural products: the model case of mixed fermentation in kombucha

Environmental Challenges
The augmented cultivation and processing of horticultural crops, coupled with insufficient handling techniques and infrastructure, have culminated in a massive accumulation of fruit and vegetable waste. This phenomenon presents challenges in the scope of

Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify
